Management: The disease can be controlled by spraying Copper oxychloride 0.25 % or Mancozeb 0.2%. Kadam et al. Ginger can have the bacteria either from the infected seed, or from direct inoculation, through wounds or natural openings. Rots caused by bacteria and fungi and grubs of insects were common in all districts and often resulted in crop … It has been a part of healing strategies in Asia, India, Europe, and the Middle East for centuries for treatment of such disorders as arthritis, stomach upset, asthma, diabetes, and menstrual irregularities, to name a few. [83] found that only 7% of the accessions have the relative resistance to the Pythium sp. Later, the yellowing diffuse to older leaves. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Application of Metalaxyl in soil is effective to control the soft rot [53]. Irregular round galls and spindle-shaped enlargements appear on the tap and side roots. See our User Agreement and Privacy Policy. Bacillus subtilis strain 1JN2, Myroides odoratimimus 3YW8, B. amyloliquefaciens 5YN8, and Stenotrophomonas maltophilia 2JW6 are used as biocontrol showed efficacies greater than 50% against bacterial wilt of ginger [29]. The effective management of ginger against the pathogen is depends up on the various factors. January 05,2017(grade4 ornamental plants), No public clipboards found for this slide. Nematodes can attack ginger and turmeric such as root-knot nematode (Meloidogyne incognita).This nematode has a very wide-host range and heavy infections may render drastic reduction of ginger yield. It is wide spread and prevailed in warm and humid environmental conditions. Le et al. them and causing pain, and ginger can be highly effective in managing it. Bacterial wilt of ginger is the most serious rhizome-borne diseases. Leaving the land fallow for 2 consecutive years reduce the pest population. Atherosclerosis, a journal focusing on the major disease of arteries, has just published a randomized, double-blind, placebo-controlled study showing that garlic appears to prevent plaque buildup in arteries. Maximum disease incidence occurred when soil temperature ranged from 24 to 25°C and the soil moisture from 25 to 30% [104]. India is the leading producer and exporter of ginger in the world. Free PowerPoint templates download takes just a few seconds and does not cause difficulties. Published on Apr 9, 2014 Ginger: Zingiber officinale is quoted as "World's healthiest food". It can be produced in many countries but it does best in moist, tropical conditions. In order to protect the plant from the persistence nature of the pathogen in soil, crop rotation with rice and corn (tolerant to pathogens of ginger) can be done to minimize the recurrence of pathogen in the next harvest [42, 43, 44]. Source-TamilNadu Agritech Portal . Affected pseudo stem becomes water soaked and the rotting spreads to the rhizome resulting in soft rot. Biotype III of the bacterium cause slow wilt and biotype IV causes rapid wilting and death [12]. J. of Spices & Aromatic Crops 4: 49-56. The disease is more prevalent in rhizomes that have formed deep in the ground. In: The Agronomy and Economy of Tumeric and Ginger: The Invaluable Medicinal Spice Crops.

This presentation talks about the production, management, its disease, pest and their management/control practices. Caused by a bacteria that enters the vascular tissue of ginger plants and multiplies until the shoots and leaves are unable to get enough water and nutrients to survive, bacterial wilt is evident by signs of water stress despite adequate watering … Erwinia chrysanthemi is the only Erwinia species responsible soft-rot of ginger. Ginger is utilized widely as a spice, for pickles, candies and as a medicinal herb. (otitid scavenger fly) and sciarid gnat fly. Virus particle contains a major coat protein with molecular weight of 29 kDa and single stranded RNA with molecular weight of 1.5 × 106 Da. populations. The plant grows well in cool weather but will tolerate a range from 9–28°C (48.2–82.4°F). At a later stage root infection is also noticed. Later, the spots developed as white papery center and dark brown margins surrounded by yellow halos [125]. The leaves of infected plants show chlorotic flecks, 1–10 mm long on the centered and parallel to the veins (Figure 1). She often works with her clients’ advisors such as financial planners and accountants. The adults are dark brown beetles and measures about 2.5 mm x 1.5 mm in size. Sinha et al. It is imperative to know the symptoms of the disease, the organism responsible and the protection measures. Fungal mycelia discolored the surface of rhizome accompanied with dry rotting and decaying (Figure 5). Incidence of storage rots is reduced while the rhizome is treated with benomyl (750 ppm) and/or gibberellic acid (150 ppm) before the storage [144]. It differs from mosaic virus in particle properties, host range and serology. Neurodegenerative diseases may be aided by ginger's ability to inhibit nitrous oxide production and proinflammatory cytokines. Virus produces mosaic disease in 18 cultivars of ginger and 23 other plant species [4]. sible with effective disease control. Among six Streptomyces species, SSC-MB-02 was effective against F. oxysporum [115]. zoospores germination and spreading. During the rainfall, the dispersal of spore occurred. Biotype III is restricted to ginger plant and its weeds whereas biotype IV infects a wide host range including potato, tomato, eggplant, Capsicum frutescens, Zinnia elegans and Physalis peruviana. Ramakrishnan [125] reported this disease first time from Godavari district of Andhra Pradesh and Malabar area of Kerala. Nematode infections aggregate the fungus and bacterial infection. The plants which are infested by the disease stand persistently and do not collapse. Srivastava [56] effectively managed P. aphanidermatum by drenching Zineb or Mancozeb in the soil after treating the rhizome with carbendazim. Similarly, T. harzianum and T. saturnisporum also showed strong antagonism against P. splendens [59]. Pathogenicity test is available for Acremonium murorum, Acrostalagmus luteo-albus, Fusarium sp., F. oxysporum, Lasiodiplodia theobromae and Sclerotium rolfsii associated storage rot [36]. The moth lay eggs on the growing bud, petiole or leaf of the young plants. Treating seed with a mixture of metalaxyl and captafol and treating the soil with the same chemicals after 3 months of planting controlled the disease [54]. Mild sunburn affects only the leaves, but acute sunburn damages the entire shoot [158]. Developing a Fusarium resistant variety would be ideal for effective yellows disease management. Six to seven months old plants are prone to infection of Phyllosticta and 2 weeks old leaves are most susceptible. Table of Contents. Maintain the field sanitation and application of Bacillus thuringiensis (1–2 g/l) prevents the leaf roller. A reduction of production costs by elimi­ nating diseases would make Hawaiian ginger more competitive in the market. As the plants put forth fresh leaves, these get infected subsequently. is soil borne pathogen survive in the soil for a long period [46]. For a class presentation, Cartman delivers a hate speech, against what he calls "gingers": people with red hair, freckles, and pale skin due to an alleged disease called "Gingervitis".He describes them as being disgusting, inhuman, unable to survive in sunlight, and having no souls. They are sedentary, endoparasitic and produce gall. It also by planting in well-drained soils, rotating susceptible plants with non-susceptible plants. Ginger leaves are occasionally damaged by grasshoppers. Assessing the concentration of virus in various parts of ginger revealed that leaves and flower possess higher concentration of virus than rhizome, stem and other parts of the plant. Five plant species were investigated to evaluate their antibacterial activity against food poisoning bacteria including two strains of Gram positive bacteria (B. cereus & S.aureus) and three strains of Gram negative bacteria (E. coli, S. typhi & P. aeruginosa) using disc diffusion method.Evaluation of antibacterial activity of these plant extracts was recorded in Table 2 and illustrated in Fig. Read our new publication: "Bacterial Wilt of Edible Ginger in Hawaii" (Oct 2013)Symptoms of bacterial wilt of ginger include: "Green wilt" is the diagnostic symptom for the disease.This symptom occurs early in the disease cycle and precedes leaf yellowing. Identifying Pythium resistant ginger is an ideal for effective soft rot disease management. [50] reported that rhizomes are protected from Pythium while treating the seed with Fytolan (copper oxychloride) (0.2%), Ridomil (500 ppm), Bavistin (carbendazim) (0.2%) and Thimet. Exposing ginger seed pieces to hot air at 75% RH until their temperatures attained 49°C for 30 and 60 min and 50°C for 30 min, resulted in minimal injury to the hosts. Mixing organic matter with poultry manure and sawdust enriched the soil microbial populations in the ginger growing soils [73] and enhance the soil carbon levels and water infiltration rates, support the growth and yield of ginger [51, 76]. Chlorotic fleck symptoms on ginger leaf (source: https://www.plantwise.org). Caterpillars bore through the central shoots, feed the growing buds resulting in withered and dried shoot referred to as “Dead Heart”. Ginger essential oil prevented liver disease and maintained healthy lipid levels in obese mice fed a high-fat diet. Available from: Physical Methods for Stimulation of Plant and Mushroom Development, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, India, Department of Plant Sciences, School of Biological Sciences, Madurai Kamaraj University, India. Application of Boerhavia diffusa leaves and seed powder of Azadirachta indica in the soil before the planting reduces the infection [63]. Metalaxyl formulations (Ridomil 5G and Apron 35 WS) in soil and treating the seed gave very good protection against soft rot [55]. Later the lesion enlarges, coalesce and cause the stem to rot and collapse [34]. Leaf spot disease is becoming increasingly important in many places of India due to severe leaf rot and blight it causes. Nematode feeds rhizomes, roots and base of the pseudo stems. Gray showed 100% resistance against F. solani [117]. Disease is not found in well-drained soils. rustica, N. glutinosa, Elettaria cardamomum, Curcuma longa, and C. aromatica. Several species of Pratylenchus namely P. brachyurus, P. coffeae, P. indicus and P. zeae are infecting ginger. Rhizomes packed in PVC film preserve the weight but has high chance of disease [150]. Built by scientists, for scientists. Disease symptoms The infection starts at the collar region of the pseudo stem and progresses upwards as well as downwards. Isolates of F. oxysporum f. sp. Screening 650 ginger accessions by Bhai et al. World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. The ginger is also affected by various insects like Conogethes punctiferalis, Aspidiella hartii, rhizome scale, rhizome fly and thrips. The disease is formed in both air black and sandy loam soil and losses upto 80 % of plants has been reported. Can be Used as a Therapy for Preventing Skin Damage. Reaction of ginger germplasm to Phyllosticta zingiberi. Nelson [16] observed that the host range of race 4 of biovar III of R. solanacearum is restricted to edible ginger. Ginger root (Zingiber officinale) is an herb that belongs to the same family as turmeric and cardamom.Aside from being a common cooking spice, ginger is also a powerful medicinal herb. Application of Beauveria bassiana or Metarhizium anisopliae with vermicompost (5 g/kg) or drenching the soil with these entomopathogenic fungi (5 g/l) reduces the pest. This disease affects inflorescence stalk may lead to severe damage to the seed crop. Researchers think ginger may help protect the liver, but this remains uncertain. Inflorescence a spike on a distinct scape; flowers densely arranged, bisexual, irregular, each subtended by a persistent scarious bract. Presentations Designers may illustrate them in a metaphoric way and deliver simplicity from complex work. Reaction of ginger germplasm to Phyllosticta zingiberi. Dr. Sudhakar Kokate Following a single approach is not ideal way to a have soft rot resistant. Strains from ginger in Hawaii showed less similarity for the strains from tomato (race 1) and heliconia (race 2) [18]. This is not considered as a major problem in ginger, but periodic outbreaks occur when ginger is planted in waterlogged soil [12]. Observations on the etiology of rhizome rot of ginger are presented for Fiji and Australia. Addition of organic matter from various plants, oil seed cakes and neem cake, reduce the incidence of soft rot [74, 75]. The prevalence of GERD symptoms appeared to increase until 1999. Treating with 1% formaldehyde and then planting the ginger under shade had lower incidence (19.4%) of soft rot as without shade (41.3%) [57]. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. The available physical, chemical, biological, methods and cultural practices to manage this pathogen are discussed below. Management: Healthy rhizomes have been obtained. Ginger plantation is majorly affected by deuteromycetous group of fungi cause variable symptoms [31]. The disease is spread mainly through contaminated rhizomes. Temperature above 30°C and high soil moisture climatic conditions favors this disease. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. Young ginger plants are very susceptible to sunburn when the temperatures exceed 90°F due to high light intensity. The rhizome gives foul smell. Page 409-426. Harrison special, N. tabacum var. Later, chlorosis from the older leaves progress to younger leaves start developing a similar symptom progression until the entire plant dies [35] (Figure 3). Extracts from Jacaranda mimosifolia and Moringa oleifera gave the best inhibitory effect of 27.7% against P. aphanidermatum [69]. Phytosanitation is needed when the symptoms of soft rot appear in the ginger plantations. Flowering ginger is a member of the Alpinia genus of Zingiberales order of Zingiberaceae family. [138] screened 100 accessions of ginger for their reaction and tolerance to leaf spot under field conditions and of them, 11 accessions were found tolerant and further 42 were moderately tolerant. It includes removing all plant debris from storage ware houses and disinfecting walls and floors with either formaldehyde or copper sulfate between harvests, maintaining low humidity and temperature of the storage facility with an adequate ventilation system. Selecting the disease free seeds, sowing the disease free seed on disease free land based on previous history, following 4–5 years of crop rotation with non-solanaceous plants, planting on raised beds (help to avoid water stagnation during rainy season), giving thick mulching (to avoid weed growth and to conserve soil moisture), reduces the disease causing potential of the soil. In Fiji, the disease generally develops during hot, wet conditions in March and April, and often causes losses of more than 50% in seed crops. Ramakr. It can lower your triglycerides and cholesterol, but it might cause a drug interaction. Soil solarization with fungicides effectively reduces the P. myriotylum [84]. Ginger is cultivated in most of the states in India. Chlorotic fleck in ginger is due to ginger chlorotic fleck virus (GCFV). Symptoms Wilt is observed in patches. were the best mulches with respect to inhibit soft rot caused by P. aphanidermatum. The importance of these insects in ginger production remains to be determined. In India, fungal diseases reduce the potential yield to a greater extent in field, storage and market and may cause losses of even more than 50% [32]. Tomatoes are one of the most cultivated crops, Tomato crops can be easily grown under proper conditions and regular maintenance.Tomato crops can host of production problems and pathogens when conditions and maintenance are not ideal. The entire crop may be lost in severely infested plantations. Grech and Frean [133] observed that spraying mixture of benomyl (0.1%), mancozeb (0.2%) and soluble boron (0.1%) and iprodione (0.2%) reduces the production of disease. It is also soil and seed-borne disease. Diseases of turmeric (Curcuma longa L.) and their management. Help us write another book on this subject and reach those readers. Due to the infection, rhizomes appear soft, brown, water soaked, rotten, and decay gradually [34] (Figure 3). Seed solarization at 47°C for 30 min within a polyethylene sheet is ideal for Pythium sp. Senapati and Sugata [81] found one resistant cultivar and eight others with moderate resistance while screening 134 ginger varieties available in Koraput, Orissa, India. We share our knowledge and peer-reveiwed research papers with libraries, scientific and engineering societies, and also work with corporate R&D departments and government entities. Small, circular, water soaked, slightly brown lesions with mature females of the nematode (Figure 6) below the epidermis of the rhizomes are quite numerous in severely infected rhizomes. Symptoms : It is the most serious disease and the symptoms can be noticed form July-August. You can change your ad preferences anytime. in the nematode infested field not only reduce the nematode but also alter the physical, chemical and biotic conditions of the soil which improve the plant growth. Pycnidia of Phyllosticta survive in the leaf debris even during the summer. Ginger essential oil prevented liver disease and maintained healthy lipid levels in obese mice fed a high-fat diet. The base of the infected pseudostem and the rhizome emit foul smell. In Fiji, the disease generally develops during hot, wet conditions in March and April, and often causes losses of more than 50% in seed crops. Green ginger leaves roll and curl due to the water stress caused by the bacteria that block the vascular systems of the ginger stems. Fusarium oxysporum f.sp. and their management. Treatment of Bacillus cepacia and T. harzianum, increased the production of rhizome as well as protect the plant from yellow disease [59]. [18] studied the genetic diversity of R. solanacearum strains collected from ginger plants growing in Hawaii island with amplified fragment length polymorphisms (AFLPs) showed a high degree of similarity between the strains with the value of 0.853. It can be readily purified from the virus ginger leaves through ultracentrifugation with a sedimentation coefficient of 111 s. The purified virus is an isometric nature with size of 28–33 nm. During the daytime, adults are usually found hiding in loose soil or among dead leaves. reduce the soft rot, 2–3 times less than that of the untreated control [66]. Soft rot is a complex disease problem and various methods should be applied to combat the disease. Hawaii Agricultural Experiment Station, University of Hawaii. 1. Treating the rhizome with aureofungin (0.02%) and Benomyl (0.2%) before the Storage, control the disease [148]. Post-harvest losses in ginger are a serious concern. None of the 18 cultivars tested in Karnataka, India were resistant to Phyllosticta leaf spot [136]. Gastroesophageal reflux disease (GERD) is the most prevalent gastrointestinal disorder in the United States, and leads to substantial morbidity, though associated mortality is rare. Decomposition of soil amendments (dry or green crop residues, oil cakes, meals, sawdust, FYM etc.) Symptoms: this disease mainly affects the radial leaves of transplanted seedlings at 3- 4 leaf stage during late March and early April. Rotting of rhizome due to the infestation of F. oxysporum (source: pestnet.org). The viral diseases of ginger are controlled in tissue cultures by heating at 50°C for 5 min [8]. Other species of Fusarium such as F. solani (Mart.) Die Karl-Franzens-Universität ist die größte und älteste Universität der Steiermark. Ginger (Zingiber officinale Roscoe) is a member of the Zingiberaceae family of plants. [159]). Physical control methods like solarization and hot water treatment have proved to be effective against the pathogen. 1. Among the various diseases, soft rot, yellows, Phyllosticta leaf spot, storage rot, bacterial wilt, mosaic, and chlorotic fleck are important. floating row covers can help to protect plants until they are old enough to withstand attacks by the beetle. The secondary spread of the disease can also take place through irrigation water and by mechanical means. Biocontrol agents like Paecilomyces lilacinus, Pasteuria penetrans and Pseudomonas fluorescens are effective against M. incognita. Adding neem cake in the soil also found to suppress P. aphanidermatum [64]. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. Dipping the rhizomes in the Allium sativum extract or immersing in a suspension of P. fluorescens and T. harzianum (0.5% for 30 min) before storage, reduce disease incidence [151]. The spots increase in size and coalesce to form larger lesions which lead to the reduction of effective photosynthetic area on the leaves. Treating with Burkholderia cepacia and T. harzianum showed production efficiency of 84% with reduction of disease incidence of 79.7% [67]. The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The Chinese rose beetle, Adoretus sinicus (Burm. Two cultivars: SG 666 [121] and Kerala local [122] are reported to have disease resistant. Soft Rot diseases caused for Pythium aphanidermatum. Fungus like F. oxysporum Schlechtend ex Fr., P. deliense Meurs and P. myriotylum Drechs. J. of Spices & Aromatic Crops 4: 40-48. Banana bract mosaic virus (BBrMV) (Potyvirus genus of the family Potyviridae), Canna yellow mottle virus (CaYMV) and Banana streak virus (BSV) of Badnavirus genus of the Caulimoviridae family are reported to infect flowering ginger [9]. It is an olive green caterpillar with a distinct black head. Moreover, most of the known activities of ginger components are based only on in vitro and in vivo studies, except for a … Increased protection is due to increase in defense enzymes such as chitinase, β-1,3-glucanase and polyphenol oxidase and promote plant growth and rhizome [67]. [149] reported that mancozeb fungicides compared to carbendazim is best chemical to protect the rhizome for the longer period from the fungus infection. To support this, last year (2018), a group from Malaysia identified that the mosaic disease in ginger was due to the CMV which is based on the partial nucleic acid sequence of coat protein (GenBank: MH355647.1). [70]. You can observe small yellowish to orange flecks or streaks in the middle of the leaves, which gets elongated spindle shaped spots surrounded by pinkish margin.. Old leaves dry first and then younger leaves. Applying organic manure, tillage and crop rotation reduces the yellows disease [76]. These include Eumerus marginatus (Grims) (syrphid fly), Euxesta quadrivittata (Macq.) Incidence of disease is higher and yield of rhizome is reduced when the ginger is cultivated continuously without the rotation of the crop [131]. Mycelium of Phyllosticta grows at 25.0–27.5°C with maximum and minimum of 32.5 and 10.0°C, respectively. Sowing of trap crops such as sorghum, maize and onion reduce the white grub infestation. Ginger has been used to treat nausea, vomiting, motion sickness, and vertigo. Fights Germs. Though entire plant is refreshingly aromatic, the underground rhizomes of this crop are valued as spice. Besides being able to prevent UVB, the content of ginger is also able to prevent skin damage. [73] found that fungal and bacterial populations were significantly greater in soil when pasture grass (Digitaria eriantha subsp. Dichocoris punctiferalis cause shoot borer in the ginger (source: Ref. Non-volatile and volatile compounds from T. viride inhibit the growth of P. myriotylum [58]. Kavita and Thomas [82] reported that Zingiber zerumbet accession is suitable candidates to obtain soft rot resistance for ginger. Indrasenan et al. Detection of R. solanacearum from rhizomes and soil through PCR was developed for bacterial wilt [19, 20, 21]. Among the biotic factors, bacteria are most important, causes wilt and soft rot. High temperatures, saturated soils and injury during seed preparation all tend to exacerbate the disease. R. solanacearum is a soil-borne disease spreads from the soil by adhering to hands, boots, tools, vehicle tires and field equipment; through water during irrigation and rainfall; and through infected ginger rhizomes [23]. In Himachal Pradesh, India none of the tested material of ginger was rated resistant to P. zingiberi, however, eight lines showed moderate resistance [137]. Severity of disease is influenced by high rainfall and when rhizomes planted in heavy clay soil with poor drainage. Botanical Facts. [39] developed PCR-RFLP based detection of isolates of Pythium by studying the genetic variation between P. myriotylum. Risk factors for complications of GERD include advanced age, male sex, white race, abdominal obesity, and tobacco use. Nageshwar Rao G. T. 1995. The above ground shoot is erect and reed-like with linear leaves that are arranged alternately on the stem. Clipping is a handy way to collect important slides you want to go back to later. It is widespread and exceedingly destructive for the ginger grows in tropical, subtropical and warm temperate regions of the world. diffusa (L.) Hook. [28] observed that streptomycin and streptopenicillin are superior over the other antibiotics against the bacterial wilt pathogen. Booster PCR method to detect P. myriotylum from the infected ginger rhizomes has been established [37]. Meloidogyne sp., Radopholus similis and Pratylenchus sp. Drake G. N. 1995. The favorable conditions like wet soil conditions, high soil moisture and soil temperature influence the development of the oospore [41]. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. Senapati et al. Nematodes in the soil increase the incidence of wilt in ginger [15]. Two sprays of neem oil 0.15 EC (1500 ppm) at 3 ml/l at 15 days interval is found to be effective. Ginger. Nambiar and Sarma [5] failed to absorb the sap transmission from ginger to ginger, ginger to Nicotiana tabacum var. 2.1 Key Oral Health Benefits of Ginger. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Infected plants show yellow leaves with less number of shoots and stunted growth. Pythium survive in plant debris as perennating oospores, an important source for infections. Fungus is the next major pathogen causes rhizome rot, soft rot, Sclerotium rot and yellows disease. Lecture 25 - Diseases of Crossandra Wilt: Fusarium solani Economic Importance In India it was first reported from Tamil Nadu in 1976. These small lesions merge and rot the rhizome. Temperature, 34°C is optimum for the germination of P. aphanidermatum and P. myriotylum spores. The affected plants wilt and dry up but do not fall on the ground in contrast to soft rot and bacterial wilt. However, states namely Karnataka, Orissa, Assam, Meghalaya, Arunachal Pradesh and Gujarat together contribute 65 per cent to the country’s total production. Chinese rose beetle (source: Vikaspedia). From the soil, this bacterium enters into the ginger plant through the roots and rhizomes via the openings where lateral roots emerge or through wounds caused while handling and by root-knot nematodes or parasitic insects [24]. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The Diseases of Ginger. The post-harvest losses are affected by various biotic and abiotic causes. Soil solarization with biological control methods is beneficial to plant growth and antagonistic to many pathogens like fungi, bacteria, nematodes, and arthropods. Control measures:. Roots are often stunted and deformed. Some common diseases. Of two major clusters formed, one was dominated by F. oxysporum and the other by F. solani. Ralstonia solanacearum Yabuuchi causes bacterial wild disease in ginger. Setty et al. Tropical group native to India and Malaysia ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 127763-YjViZ 3. Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions.
