During the infection process, female nematode attains the maturity and emerges from the gall by breaking the epidermis of the rhizome which gives corky in appearance for rhizome. 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. Bacterium causes rapid wilt in ginger within 5–10 days of the infection [10]. Diseases of Ginger Ginger Bacterial Wilt Ginger Leaf spot Ginger Soft rot. (21,22,23,24,25) Gastric Distress: Ginger's ability to ease gastric distress is superior, and it does more than simply ease pain. The disease is formed in both air black and sandy loam soil and losses upto 80 % of plants has been reported. [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. Control measures:. Basic requirements Garlic is a hardy perennial which can be grown in a variety of soil types. Smith and Abbas [51] focused on cultural practices with strict quarantine procedure to manage the disease. Gastroesophageal reflux disease (GERD) is the most prevalent gastrointestinal disorder in the United States, and leads to substantial morbidity, though associated mortality is rare. Soft rot is a complex disease problem and various methods should be applied to combat the disease. 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]. If you continue browsing the site, you agree to the use of cookies on this website. Chlorotic fleck in ginger is due to ginger chlorotic fleck virus (GCFV). Identifying Pythium resistant ginger is an ideal for effective soft rot disease management. Extracts from Jacaranda mimosifolia and Moringa oleifera gave the best inhibitory effect of 27.7% against P. aphanidermatum [69]. It is an olive green caterpillar with a distinct black head. Applications of bioagents such as T. harzianum, P. fluorescens and B. subtilis together reduce the disease than individually on the rhizomes (8.64%) as well as on tillers (12.50%) [87]. Diameter of gall is 3.3 cm. Disease cause significant losses during warm and humid conditions. The lesions serve as entry points for bacteria and fungi, invade, extend the injury into other tissues and destroy the rhizomes. Sowing of trap crops such as sorghum, maize and onion reduce the white grub infestation. 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. The effective management of ginger against the pathogen is depends up on the various factors. 1.1 Economic and Social Impact of Ginger In the 1980s, ginger world production was estimated at 100,000 t, but because of the several Strains from ginger in Hawaii showed less similarity for the strains from tomato (race 1) and heliconia (race 2) [18]. The presence of a bore hole on the pseudo stem through which frass is extruded and withered and yellow central shoot is a characteristic symptom of pest infestation. 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]. This presentation talks about the production, management, its disease, pest and their management/control practices. Soil drenching with Zineb, captafol, methyl bromide, mercuric chloride, thiram, phenyl mercury acetate, copper oxide and mancozeb protect the ginger crop from soft rot disease [52]. The presence of Mancozeb was observed at 120th days of storage. Planting the seed rhizome (size of 50–75 g) with spacing of 25 × 30 cm is ideal for good yield and lower disease incidence [120]. Plot. January 05,2017(grade4 ornamental plants), No public clipboards found for this slide. Rhizome treatment in hot water at 47°C for 30 min and drenching of soil T. harzianum, followed by mancozeb are most effective in inhibiting Pythium sp. rustica, N. glutinosa, Elettaria cardamomum, Curcuma longa, and C. aromatica. Application of fungicides such as metalaxyl, Ridomil, Maxam XL (fludioxonil) and Proplant (propyl carbamate hydrochloride) on seed give significantly better result for P. myriotylum than carbendzim alone [51]. It has been a part of healing strategies in Asia, India, Europe, and the Middle East for This chapter emphasizes the importance of diseases of ginger by including the symptoms, causative agent, epidemiology and protection from these diseases. Submitted: April 10th 2019Reviewed: July 26th 2019Published: September 24th 2019, Home > Books > Ginger Cultivation and Its Antimicrobial and Pharmacological Potentials. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. It is caused by the plant parasitic nematode, Meloidogyne sp. Native to South eastern Asia is used in dishes as delicacy, medicine / spice. How? Dark brown necrotic lesion is observed in nematode infected rhizomes. Erwinia chrysanthemi is the only Erwinia species responsible soft-rot of ginger. Old leaves dry first and then younger leaves. The plants perform best when planted in a light, well draining, organic loam with a pH between 6.0 and 7.0. Spraying 0.1% malathion at monthly interval from July to August will check out this. 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. Using soil with higher clay content and lower pH, suppress P. zingiberum and F. oxysporum [45]. Cultural practices such as seed selection, crop rotation, organic amendment, tillage, drainage and quarantine practicing in ginger plantation not only control the disease but also limit the spread of Pythium spp. Ginger Skinner enjoys providing expert advice and personable service to her clients to address their personal and corporate legal needs. Kavita and Thomas [82] reported that Zingiber zerumbet accession is suitable candidates to obtain soft rot resistance for ginger. The fungus spreads through infected seed rhizomes and about 87% of field infection is due to infected rhizomes [102]. Application of nematicides like Thimet or Phorate (12–15 kg/ha) followed by light irrigation before the sowing reduce the incidence of nematode. Diabetes. Free PowerPoint templates download takes just a few seconds and does not cause difficulties. The rot that occurs on ginger is typically a wet weather disease, influence by heavy rains after planting. Roots are often stunted and deformed. It is consumed across the globe and has immense healing power for various disorders such as High BP, Osteoarthritis, Migraine, Gastrointestinal problems, etc. 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]. Abiotic factor causes sunburn (due to high light intensity) and lime-induced chlorosis (due to excessive liming in soil) in the ginger crop. Reaction of ginger germplasm to Phyllosticta zingiberi. The seasonal carryover of fungus inoculum takes place through infected rhizomes and soil. But the health point of human, carbendazim treated rhizomes is safe than mancozeb treated rhizome Pre-storage treatment of rhizome with Topsin-M and Bavistin (each at 0.2% concentration for 60 min) reduce the appearance of disease on rhizome, increase the weight of rhizome, surface shriveling and sprouting of rhizomes [31]. Pathogen form watery and brown lesions in the collar region of the pseudo stem. 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 … ), (Figure 10) is pale reddish-brown and has nocturnal feeding habits. Sinha et al. Rhizomes become soft and watery with a creamy discoloration of the vascular system and cortical rot. Verma and Vyas [134] observed higher protection while spraying carbendazim (0.15%) and mancozeb (0.25%) and due to this higher yield also obtained. 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]. Streptocyclin (20 g/100 l water) treatment on seed and drenching the soil with 0.2% copper oxychloride, protect the seed from the bacteria infection. populations with lower disease incidence [86]. Certain chemical compounds in fresh ginger help your body ward off germs. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Elsevier Inc. Trujillo E. E. 1964. Inflorescence a spike on a distinct scape; flowers densely arranged, bisexual, irregular, each subtended by a persistent scarious bract. The pseudo stems from the infected plant can be easily separated with a gentle pull and can be broken off at the base. See our User Agreement and Privacy Policy. Higher precipitation along with high wind give greater impact on dispersion of spores to many leaves which are in longer distances [128]. zoospores germination and spreading. Bacterial Wilt. Ralstonia solanacearum Yabuuchi causes bacterial wild disease in ginger. World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. It is wide spread and prevailed in warm and humid environmental conditions. The entire crop may be lost in severely infested plantations. Treating the plant with Bordeaux mixture, zineb and maneb are effective in treating the disease [132]. Moreover, most of the known activities of ginger components are based only on in vitro and in vivo studies, except for a … Major problems of Ginger crop growing. 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. The fingers are severely affected by this nematode. Biotype II is reported to infect only potato plants [13]. Senapati et al. J. of Spices & Aromatic Crops 4: 40-48. Sometime, the eggs laid on the decaying flower stalk, develop into larva, reaches the rhizome and reduce the quality of rhizome [160]. Some experts recommend that people with gallstone disease use caution with ginger because it may increase the flow of bile. Adding neem cake in the soil also found to suppress P. aphanidermatum [64]. In: The Agronomy and Economy of Tumeric and Ginger: The Invaluable Medicinal Spice Crops. Later the lesion enlarges, coalesce and cause the stem to rot and collapse [34]. China, India, Nepal and Thailand are the major producers of ginger in the world. [62] showed inhibition of P. aphanidermatum with treatment of fresh and stored cow urine at a concentration of 20% (v/v). India is considered as a ‘magical land of spices’ with diverse variety of spices. A reduction of production costs by elimi­ nating diseases would make Hawaiian ginger more competitive in the market. Disease causes 74% of reduction in rhizome weight. This is not considered as a major problem in ginger, but periodic outbreaks occur when ginger is planted in waterlogged soil [12]. Application of Jeevatu based organic liquid manure in the field, control the soft rot and the spreading of this disease [65]. Thw., Boerhavia repens L. var. Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. The larvae apparently feed on decaying plant material; pupation occurs in the soil. Hot-water and hot-air treatments of affected rhizomes at 45 and 50°C for 3, 6, and 12 h does not alleviate symptoms [5]. Die Karl-Franzens-Universität ist die größte und älteste Universität der Steiermark. Pythium survive in plant debris as perennating oospores, an important source for infections. 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. The leaf margins of the affected plant turn bronze and curl backward. Hawaii Agricultural Experiment Station, University of Hawaii. The virus is transmitted by insect vectors such as Myzus persicae, M. certus, M. humuli, Macrosiphum euphorbiae and Rhopalosiphum insertum. Nematode produces root knot disease and virus’s causes mosaic and chlorotic fleck in ginger plants reduce the yield of the rhizome. Diseases of ginger (Zingiber officinale Rosc.) The damage on the foliage is characteristic, being peppered or shot with holes, or more or less skeletonized. 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]. Post-harvest losses in ginger are a serious concern. [78] also reported that Schima wallichii and Datura spp. Ginger crop is being affected by insect pests, and pathogenic and non-pathogenic diseases cause production constraints. Fungus is the next major pathogen causes rhizome rot, soft rot, Sclerotium rot and yellows disease. Their severity, plus the fact that ginger is the only cash crop of a majority of small farmers, was a decisive factor in choosing the crop for ISPS assistance. 3.1 Ginger in the Raw; 3.2 Ginger Tea Recipe The resistance is due to the presence of a resistance (R) gene of CC–NBS–LRR [123]. Different workers obtained variable results and none of the tested cultivars showed high degree of resistance [137, 138]. 1. 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]. Further, sulfur nanoparticles with fungicides like bavistin, ridomil gold, sunflex and streptocycline were evaluated for the inhibition of the fungus showed that sulfur nanoparticles with bavistin with high inhibition. The above ground shoot is erect and reed-like with linear leaves that are arranged alternately on the stem. However, losses still occur in the [80] identified Supraba and Himachal Pradesh cultivars showing less than 3% soft rot incidence. Observations on the etiology of rhizome rot of ginger are presented for Fiji and Australia. The moth lay eggs on the growing bud, petiole or leaf of the young plants. Biocontrol agents like Paecilomyces lilacinus, Pasteuria penetrans and Pseudomonas fluorescens are effective against M. incognita. Other species of Fusarium such as F. solani (Mart.) It is widespread and exceedingly destructive for the ginger grows in tropical, subtropical and warm temperate regions of the world. is soil borne pathogen survive in the soil for a long period [46]. Hawaii Agricultural Experiment Station, University of Hawaii. Yellowing starts on the margins of the lower leaves which gradually spreads and cover the entire leaves. [159]). The disease is spread mainly through contaminated rhizomes. [30] suggested selection of healthy seed rhizomes, eradication of weeds and adoption of an effective crop rotation as control measures for the disease. [22] reported the complete genome sequence of R. solanacearum SD54, a race 4 biovar 4 (R4B4) strain from a diseased ginger plant. Management: Healthy rhizomes have been obtained. Fungal mycelia discolored the surface of rhizome accompanied with dry rotting and decaying (Figure 5). Gray showed 100% resistance against F. solani [117]. 3. Soft Rot diseases caused for Pythium aphanidermatum. Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. Incidence of disease is higher and yield of rhizome is reduced when the ginger is cultivated continuously without the rotation of the crop [131]. Pythium myrotylum causes a serious disease. It is considered as the second most important destructive bacterial pathogens identified to date. Treating rhizomes with Ridomil MZ (metalaxyl and mancozeb) and soil drenching with Thimet (Phorate) and Ridomil MZ after planting gave the best control of P. myriotylum. Poor drainage system and water logging increases the intensity of the disease. Some diseases of minor importance have also been reported on ginger like Cercospora leaf spot caused by Cercospora zingibericola [153], anthracnose caused by Colletotrichum zingiberis [154], Pyricularia leaf spot caused by Pyricularia zingiberi [155], basal rot caused by Sclerotium rolfsii [92, 156] and Septoria leaf spot caused by Septoria zingiberis [157]. It is an important to have a multiple approach. Sacc., F. equiseti (Corda) Sacc., F. graminearum Schwabe, F. moniliforme Sheld and some unidentified Fusarium spp. Ginger is cultivated in most of the states in India. Microorganisms like Trichoderma harzianum and Gliocladium virens [112], T. viride and T. harzianum [113], T. viride [114] inhibits F. oxysporum. Meloidogyne sp., Radopholus similis and Pratylenchus sp. The leaf margins turn into brown and curl back -wards. [73] found that fungal and bacterial populations were significantly greater in soil when pasture grass (Digitaria eriantha subsp. Brown lesions on the root knot nematode infected rhizome (below) (source: http://www.eastbranchginger.com). Symptoms Wilt is observed in patches. 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. It is very difficult to control this. 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. Ginger is one of the high value commercial crop of Nepal. Ginger essential oil prevented liver disease and maintained healthy lipid levels in obese mice fed a high-fat diet. Though entire plant is refreshingly aromatic, the underground rhizomes of this crop are valued as spice. Infested plants show stunting, chlorosis and marginal necrosis of leaves. It is consumed across the globe and has immense healing power for various disorders such as High BP, Osteoarthritis, Migraine, Gastrointestinal problems, etc. Pest infestation leads to yellowing of the leaves. It is also soil and seed-borne disease. © 2019 The Author(s). Storing the rhizomes in lower temperature avoid weight loss, increase the sprouting but with higher risk of infection when comparing with storage at room temperature. Difficulties are associated with controlling this pathogen due to its endophytic nature, survive in deep soil, travel along water, and its relationship with weeds. Reduction of soft rot occurred when seed was first disinfested with HOCl (1%) followed by soaking in Trichoderma spp. Login to your personal dashboard for more detailed statistics on your publications. The severity of the disease is occurred due to the rapid spread of the pathogen happens during the favorable environment conditions like high rain fall and warm weather. Younger sprouts are the most susceptible to this disease. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? None of the 18 cultivars tested in Karnataka, India were resistant to Phyllosticta leaf spot [136]. The total production of ginger in the world is 1683 thousand tons with the total acreage of 310.43 thousand ha [1]. Rhizome Flies: Treating seed with Ridomil MZ (1.25 g/L) increase the survival of rhizomes (about 30%) in comparison to hot water treatment (at 51°C for 30 min) [49]. Non-volatile and volatile compounds from T. viride inhibit the growth of P. myriotylum [58]. The affected plants wilt and dry up but do not fall on the ground in contrast to soft rot and bacterial wilt.
