Morphological, cultural, pathological and molecular variability among F. oxysporum f.sp. Bacteria secrete pectolytic enzymes degrade and break the cells providing more food for the bacteria. Just press one button and get the necessary element! It is also soil and seed-borne disease. Learn more about the importance, transmission, diagnosis, and control of plant diseases. zingiberi differed in their aggressiveness [99]. Fr. Observations on the etiology of rhizome rot of ginger are presented for Fiji and Australia. The best time to plant ginger is in spring. Syrphid fly may be a threat to ginger when the crop becomes dormant. 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. Diseases of ginger (Zingiber officinale Rosc.) She often works with her clients’ advisors such as financial planners and accountants. In Fiji, losses from soft rot are common, with 30-100% of the fields destroyed in the wetter parts of the country. Several rhizobacteria were reported to possess strong antagonistic activity on P. myriotylum growth [60]. [77] reported that neem seed cake with least average mortality (20.3%) followed by poultry manure (22.7). The ginger is also affected by various insects like Conogethes punctiferalis, Aspidiella hartii, rhizome scale, rhizome fly and thrips. These include Eumerus marginatus (Grims) (syrphid fly), Euxesta quadrivittata (Macq.) The plants which are infested by the disease stand persistently and do not collapse. 1. Isolates of F. oxysporum f. sp. Pests and diseases of ginger abound in Sikkim. The Chinese rose beetle, Adoretus sinicus (Burm. [39] developed PCR-RFLP based detection of isolates of Pythium by studying the genetic variation between P. myriotylum. A manual on the most important pests and diseases of the major food crops grown by smallholder farmers in Africa. Among the 11 species, P. myriotylum and P. aphanidermatum cause severe damage in warm climates. If you continue browsing the site, you agree to the use of cookies on this website. Diseases of turmeric (Curcuma longa L.) and their management. Adoption of Integrated Pest (Disease) Management against the diseases encountered in vegetable crops is of paramount importance as most of the vegetable crops are not harvested at the end of the crop season but it is spread over a long duration by way of several pickings, as in case of tomato, okra, cucurbits, pea, beans, etc. Nageshwar Rao G. T. 1995. in height,. Our readership spans scientists, professors, researchers, librarians, and students, as well as business professionals. Fights Germs. Chlorotic fleck symptoms on ginger leaf (source: 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. Bird's eye spot Cercoseptoria ocellata = Cercospora theae Pseudocercospora theae = Septoria theae = Cercoseptoria theae. The various strategies like seed protection (biologically, physically or in combination), seed disinfestations (to control spores on the seed surface), seed disinfection (to eliminate pathogens living inside the cells) such as chemical infusion protect the seed from the infection as well as improve the germination of seeds [42]. Soil solarization with biological control methods is beneficial to plant growth and antagonistic to many pathogens like fungi, bacteria, nematodes, and arthropods. The importance of these insects in ginger production remains to be determined. Udaspes folus causes leaf roller in ginger (source: Ref. Symptoms Wilt is observed in patches. In some people, ginger can have mild side effects such as abdominal discomfort, heartburn, diarrhea, and gas. Using a high-tech ultrasound device, the researchers measured plaque volume in the upper body’s carotid artery. Diseases: Ginger is prone to several diseases, some of which may cause heavy losses. Strains from ginger in Hawaii showed less similarity for the strains from tomato (race 1) and heliconia (race 2) [18]. Nelson [16] observed that the host range of race 4 of biovar III of R. solanacearum is restricted to edible ginger. It is considered as the second most important destructive bacterial pathogens identified to date. Its antiinflammatory ability may be helpful in arthritis, cancer prevention, prostate disease, and general inflammatory processes. Licensee IntechOpen. 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. 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. The virus is transmitted through the sap to different plants which are believed to the hosts of CMV [4]. Ginger is protected from the shoot borer by collecting the entire emerged adult, destroying and by installing light trap for adult mass trapping, destroying infested plant and by chemical application of Metarhizium and treating with Beauveria bassiana. and Tithonia diversifolia A. J. of Spices & Aromatic Crops 4: 49-56. Butler on 1907, recorded this disease first time in Surat district of Gujarat, India [33]. Indrasenan et al. xanthi, N. tabacum var. © 2019 The Author(s). Ginger is cultivated in most of the states in India. Rots caused by bacteria and fungi and grubs of insects were common in all districts and often resulted in crop … Plant diseases can be classified as infectious or noninfectious, depending on the causative agent. Bacterium causes rapid wilt in … Rhizome treatment with copper oxychloride followed by neem extract, suppresses the soft rot disease [88]. Yellowing starts from the lower-most leaves which gradually progresses upwards. 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. Brief introduction to this section that descibes Open Access especially from an IntechOpen perspective, Want to get in touch? Yu et al. [149] reported that mancozeb fungicides compared to carbendazim is best chemical to protect the rhizome for the longer period from the fungus infection. Different workers obtained variable results and none of the tested cultivars showed high degree of resistance [137, 138]. It was first described by Simmonds [90] from Queensland. The content oil in ginger can prevent UVB. zingiberi isolates with DNA amplification fingerprinting (DAF) segregated the isolates into three haplotypes based on 17 polymorphic bands generated with five primers [100]. Ginger leaves are occasionally damaged by grasshoppers. [110] reported lowest yellows disease while treating with Ridomil Gold along with poultry waste, Bavistin 50WP, Dithane M-45 and saw dust in the soil at 240th days of planting. Infected pseudo stem comes off from the rhizome with a gentle pull. Fungal mycelia discolored the surface of rhizome accompanied with dry rotting and decaying (Figure 5). For the development of yellows disease, a temperature range of 15–30°C is favorable (the optimum being 23–29°C) with very high humidity and continuous presence of free water [103]. Verma and Vyas [134] observed higher protection while spraying carbendazim (0.15%) and mancozeb (0.25%) and due to this higher yield also obtained. Nageshwar Rao G. T. 1995. Similarly, T. harzianum and T. saturnisporum also showed strong antagonism against P. splendens [59]. Rhizomes become soft and watery with a creamy discoloration of the vascular system and cortical rot. J. of Spices & Aromatic Crops 4: 49-56. Nematode produces root knot disease and virus’s causes mosaic and chlorotic fleck in ginger plants reduce the yield of the rhizome. Among the various nanoparticles synthesized from plants, a sulfur nanoparticle has high inhibitory effect on F. oxysporum [118]. Molecular variability revealed 0 to 80% variation among 19 isolates and they were grouped into two different major groups each comprising of 10 and 9 isolates, respectively. It is one of the commonly consumed dietary condiments in the world and has high medicinal properties. In Himachal Pradesh, India none of the tested material of ginger was rated resistant to P. zingiberi, however, eight lines showed moderate resistance [137]. (2013b) studied genetic variability of 32 Fusarium isolates from diseased ginger rhizomes from Western Himalayas in India. The plants perform best when planted in a light, well draining, organic loam with a pH between 6.0 and 7.0. In the advanced stage, infected ginger exhibit intense yellowish and wilting symptoms (Figure 2). The prevalence of GERD symptoms appeared to increase until 1999. Singh A. K. 2000. The virus is transmitted by insect vectors such as Myzus persicae, M. certus, M. humuli, Macrosiphum euphorbiae and Rhopalosiphum insertum. 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. Later, chlorosis from the older leaves progress to younger leaves start developing a similar symptom progression until the entire plant dies [35] (Figure 3). No obvious symptoms occur on the rhizomes. Pythium ultimum, Fusarium oxysporum and Verticillium chlamydosporium are responsible for storage rot. populations. Mancozeb and carbendazim together treatment on ginger rhizomes protect the rhizomes from the rot [146, 147]. Inflorescence a spike on a distinct scape; flowers densely arranged, bisexual, irregular, each subtended by a persistent scarious bract. Plant disease-free ginger by using pathogen-free seed. Green ginger leaves roll and curl due to the water stress caused by the bacteria that block the vascular systems of the ginger stems. Spraying 0.1% malathion at monthly interval from July to August will check out this. In: The Agronomy and Economy of Turmeric and Ginger: The Invaluable Medicinal Spice Crops. periods, and thus can be marketed … This presentation talks about the production, management, its disease, pest and their management/control practices. Later, the spots developed as white papery center and dark brown margins surrounded by yellow halos [125]. Pythium survive in plant debris as perennating oospores, an important source for infections. At a later stage root infection is also noticed. Ginger, when used as a spice, is believed to be generally safe. Disease cause significant losses during warm and humid conditions. Decomposition of soil amendments (dry or green crop residues, oil cakes, meals, sawdust, FYM etc.) [130] found that PGS-16, PGS-17 and Anamica as moderately resistant out of 135 ginger cultivars tested. During storage, rhizomes soft are affected by fungi [71] and bacteria. [141], Cladosporium tenuissimum, Gliocladium roseum Bainer, Graphium album (Corda) Sacc., Mucor racemosus Fresen., Stachybotrys sansevieriae, Thanatephorus cucumeris (Frank) donk and Verticillium chlamydosporium Goddard [142]. Chlorotic fleck in ginger is due to ginger chlorotic fleck virus (GCFV). Symptoms first appear on the aerial parts of the plant. It is an olive green caterpillar with a distinct black head. Often the epidermis is left unscathed, keeping the rotten flesh contained within until a crack allows the ooze to leak out and infect others around it. Mycelial growth in the form of white, peach or buff colored cushions can be seen on the surface of rhizomes [93]. Initially, water soaked patches or linear streaks appear at the collar region of the pseudo stem and then progresses both upwards and downwards. The leaf margins of the affected plant turn bronze and curl backward. Myzus persicae and M. certus are comparatively more efficient vectors for this virus. Plants may show a premature drooping, wilting, yellowing, drying in patches or in whole bed and show stunting. Old leaves dry first and then younger leaves. Fungus is the next major pathogen causes rhizome rot, soft rot, Sclerotium rot and yellows disease. High temperatures, saturated soils and injury during seed preparation all tend to exacerbate the disease. Physical control methods like solarization and hot water treatment have proved to be effective against the pathogen. The infective stage of the nematode is the second stage juveniles, which have lightly sclerotized cephalic framework. Fungal diseases; Anthracnose Colletotrichum theae-sinensis = Gloeosporium theae-sinensis. Holotrichia responsible for white grub in ginger (source: Ref. Bacterial wilt of ginger is the most serious rhizome-borne diseases. Clipping is a handy way to collect important slides you want to go back to later. Identifying Pythium resistant ginger is an ideal for effective soft rot disease management. [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. Native to South eastern Asia is used in dishes as delicacy, medicine / spice. Ginger: Zingiber officinale is quoted as "World's healthiest food". them and causing pain, and ginger can be highly effective in managing it. Yellowing starts on the margins of the lower leaves which gradually spreads and cover the entire leaves. The lesions serve as entry points for bacteria and fungi, invade, extend the injury into other tissues and destroy the rhizomes. Planting the disease free rhizomes is the best method to manage the disease [71]. It affects roots and rhizome severely. 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. Disease symptoms The infection starts at the collar region of the pseudo stem and progresses upwards as well as downwards. The symptoms of root knot are very similar to root gall. Having soil solarization for longer periods reduces Pythium spp. Poor drainage system and water logging increases the intensity of the disease. Ginger An Overview of Health Benefits Keith Singletary, PhD Ginger (Zingiber officinale Roscoe) is a member of the Zingiberaceae family of plants. Insect involved in spreading the pathogens responsible for the diseases and also involved in damaging the foliage and rhizomes. It can lower your triglycerides and cholesterol, but it might cause a drug interaction. 2.1.1 Ginger Can Help Fight Against Gingivitis and Gum Disease; 2.1.2 Active Ingredient #1: Raffinose for Plaque Defense; 2.1.3 Active Ingredient #2: Gingerol for Fighting Infection; 3 How to Consume Ginger for Your Oral Health. Rotting of rhizome due to the infestation of F. oxysporum (source: Indrasenan and Paily [79] identified Maran cultivar resistant against P. aphanidermatum. Ginger is being cultivated in the various parts of the world. Diseases of Ginger Ginger Bacterial Wilt Ginger Leaf spot Ginger Soft rot. Diseases of Ginger (Zingiber officinale) in Hawaii. It causes extensive damage to cortical tissues of root. Ginger crops on this infested soil severely affected and completely lost to the disease [16]. Annually, India produces 385.33 thousand tons of ginger [1]. The viral diseases of ginger are controlled in tissue cultures by heating at 50°C for 5 min [8]. The eggs, which are laid in the soil, hatch in about 4 days, and the entire life cycle from egg to adult takes about 6–7 weeks. 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]. Singh A. K. 2000. diffusa (L.) Hook. Diseases of Ginger, Ginger Cultivation and Its Antimicrobial and Pharmacological Potentials, Haiping Wang, IntechOpen, DOI: 10.5772/intechopen.88839. If you continue browsing the site, you agree to the use of cookies on this website. Rakesh et al. Steeping of rhizomes in carbendazim (0.1%) for 60 min before storage also controlled storage rots and reduced the disease incidence from 71.4 to 18.2% [112]. This pest is prevalent in the field at low elevations [160]. Two haplotypes showed very little genetic variation (98.6% similarity), whereas the third haplotype was quite distinct in terms of its molecular profile (77.2% similarity). Growing the crop under the partial shade reduce the severity of Phyllosticta leaf spot. Important also is the fact that disease­ free rhizomes can be stored for longer . Among the biotic factors, bacteria are most important, causes wilt and soft rot. Ginger plantation is majorly affected by deuteromycetous group of fungi cause variable symptoms [31]. 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]. is the best biocontrol agents for soft rot. Infestation of the nematodes causes yellowing of leaves and dry rot on rhizome. Young ginger plants are very susceptible to sunburn when the temperatures exceed 90°F due to high light intensity. Mild sunburn affects only the leaves, but acute sunburn damages the entire shoot [158]. The rot that occurs on ginger is typically a wet weather disease, influence by heavy rains after planting. It is imperative to know the symptoms of the disease, the organism responsible and the protection measures. The leaves of infected plants show chlorotic flecks, 1–10 mm long on the centered and parallel to the veins (Figure 1). The leaf margins turn into brown and curl back -wards. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. in height,. Yellows disease is serious problems of ginger causes stem and rhizome rot. The new season has a clip of South Park's version of his video.Follow me on It is widespread and exceedingly destructive for the ginger grows in tropical, subtropical and warm temperate regions of the world. [80] identified Supraba and Himachal Pradesh cultivars showing less than 3% soft rot incidence. It differs from mosaic virus in particle properties, host range and serology. 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]. is soil borne pathogen survive in the soil for a long period [46]. Six to seven months old plants are prone to infection of Phyllosticta and 2 weeks old leaves are most susceptible. 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. Ginger: Zingiber officinale Hawaii Agricultural Experiment Station, University of Hawaii. Detection of R. solanacearum from rhizomes and soil through PCR was developed for bacterial wilt [19, 20, 21]. From the family Zingiberaceae. Later this disease was reported from Hawaii [91] and India [92]. 2.1 Key Oral Health Benefits of Ginger. The purified virus particle showed positive to serological reaction for cucumber mosaic virus (CMV) antiserum. This disease is prevalent in ginger crop throughout the growing period. Diabetes. Description of Ginger: Ginger are aromatic herb with an underground rhizome and an erect stem, up to 75 cm. The resistance is due to the presence of a resistance (R) gene of CC–NBS–LRR [123]. Diseases of tumeric (Curcuma longa L.) and their management. Bacterial wilt of ginger is the most serious rhizome-borne diseases. Though entire plant is refreshingly aromatic, the underground rhizomes of this crop are valued as spice. and followed by three applications of talc-based formulation (3 × 106 CFU/g) to the soil at 15 day intervals from the time of planting [67]. Adam M. Kaye PharmD, FASCP, FCpha, in Anesthesia and Uncommon Diseases (Sixth Edition), 2012. These flies breed in decayed plant tissues of ginger. Symptoms appear first on younger leaves. Metalaxyl formulations (Ridomil 5G and Apron 35 WS) in soil and treating the seed gave very good protection against soft rot [55]. Nageshwar et al. The water mould can destroy rhizomes in 1-2 weeks. Among the various diseases, soft rot, yellows, Phyllosticta leaf spot, storage rot, bacterial wilt, mosaic, and chlorotic fleck are important. Treating the rhizomes with mancozeb, ziram, guazatine, propineb and copper oxychloride for 30 min effectively control this pathogen [47, 48]. Treating the rhizome with aureofungin (0.02%) and Benomyl (0.2%) before the Storage, control the disease [148]. 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. Severe Nematode infestation can lead to rhizome rot disease. Pycnidia of Phyllosticta survive in the leaf debris even during the summer. The rhizome gives foul smell. The Diseases of Ginger. 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 … 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]. It folds the leaves and stays inside the fold and defoliates the leaves from the tip and margins. The secondary spread of the disease can also take place through irrigation water and by mechanical means. Rhizomes are stored for seed and commercial purpose. It can be produced in many countries but it does best in moist, tropical conditions. In the old leaves, initially, yellowing (chlorosis) symptoms appear in the tips, which then spread downward along the margin involving the rest of the leaf blade and, eventually, the leaf sheath. Disease causes 74% of reduction in rhizome weight. The plant grows well in cool weather but will tolerate a range from 9–28°C (48.2–82.4°F). The seasonal carryover of fungus inoculum takes place through infected rhizomes and soil. Nematodes in the soil increase the incidence of wilt in ginger [15]. Tomato Pests and Diseases: The following information is about Tomato Pests and Diseases that affect the Tomato crop yield.. The fungus survives in soil as chlamydospores which may remain viable for many years in the field. This disease affects inflorescence stalk may lead to severe damage to the seed crop. Ginger likes warm and humid climate. Inflorescence a spike on a distinct scape; flowers densely arranged, bisexual, irregular, each subtended by a persistent scarious bract. 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. CorporateComplexSimplicity - Presenters should always have a story as a presentation backbone. Tropical group native to India and Malaysia ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on - id: 127763-YjViZ 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]. 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]. Dr. Sudhakar Kokate Temperature, 34°C is optimum for the germination of P. aphanidermatum and P. myriotylum spores. [159]). The disease is formed in both air black and sandy loam soil and losses upto 80 % of plants has been reported. rustica, N. glutinosa, Elettaria cardamomum, Curcuma longa, and C. aromatica. Native to South eastern Asia is used in dishes as delicacy, medicine / spice. The entire crop may be lost in severely infested plantations. 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. Immersing the rhizome in carbendazim (0.1%) for 60 min reduce the disease from 71.4 to 18.2% [112]. Fly ) and their management seed solarization at 47°C for 30 min ) also reduces P.!
