Booster PCR method to detect P. myriotylum from the infected ginger rhizomes has been established [37]. in height,. The Diseases of Ginger. Diseases: Ginger is prone to several diseases, some of which may cause heavy losses. 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]. Plants may show a premature drooping, wilting, yellowing, drying in patches or in whole bed and show stunting. 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]. Disease symptoms The infection starts at the collar region of the pseudo stem and progresses upwards as well as downwards. Green ginger leaves roll and curl due to the water stress caused by the bacteria that block the vascular systems of the ginger stems. 8. Nematodes in the soil increase the incidence of wilt in ginger [15]. Old leaves dry first and then younger leaves. 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. Treating with Burkholderia cepacia and T. harzianum showed production efficiency of 84% with reduction of disease incidence of 79.7% [67]. January 05,2017(grade4 ornamental plants), No public clipboards found for this slide. Eleven species of Pythium are responsible for the soft rot diseases in ginger are identified so far. Syrphid fly may be a threat to ginger when the crop becomes dormant. Verma and Vyas [134] observed higher protection while spraying carbendazim (0.15%) and mancozeb (0.25%) and due to this higher yield also obtained. Among the 11 species, P. myriotylum and P. aphanidermatum cause severe damage in warm climates. Rhizomes become soft and watery with a creamy discoloration of the vascular system and cortical rot. The presence of Mancozeb was observed at 120th days of storage. Young ginger plants are very susceptible to sunburn when the temperatures exceed 90°F due to high light intensity. The lesions serve as entry points for bacteria and fungi, invade, extend the injury into other tissues and destroy the rhizomes. White grub caused by Holotrichia spp. Fungal mycelia discolored the surface of rhizome accompanied with dry rotting and decaying (Figure 5). Incidence of disease is higher and yield of rhizome is reduced when the ginger is cultivated continuously without the rotation of the crop [131]. Physical control methods like solarization and hot water treatment have proved to be effective against the pathogen. The present chapter includes the symptoms, causative agent, disease cycle, epidemiology and host resistance, cultural, biological, chemical, and integrated management of these diseases. Phyllosticta leaf spot is caused by Phyllosticta zingiberi T.S. zingiberi Trujillo is a causative agent for yellow disease [94]. (2013b) studied genetic variability of 32 Fusarium isolates from diseased ginger rhizomes from Western Himalayas in India. Now customize the name of a clipboard to store your clips. J. of Spices & Aromatic Crops 4: 40-48. Nageshwar Rao G. T. 1995. The resistance is due to the presence of a resistance (R) gene of CC–NBS–LRR [123]. [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. Rhizomes packed in PVC film preserve the weight but has high chance of disease [150]. 1. Using soil with higher clay content and lower pH, suppress P. zingiberum and F. oxysporum [45]. Temperature, 34°C is optimum for the germination of P. aphanidermatum and P. myriotylum spores. 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 Ginger (Zingiber officinale Roscoe) is a member of the Zingiberaceae family of plants. Addition of organic matter from various plants, oil seed cakes and neem cake, reduce the incidence of soft rot [74, 75]. them and causing pain, and ginger can be highly effective in managing it. The symptoms appear with yellowish and dark-green mosaic on leaves of ginger in the early stage and stunted of leaves and rhizomes at the late stage of infection. 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. Researchers think ginger may help protect the liver, but this remains uncertain. Diseases of Ginger Ginger Bacterial Wilt Ginger Leaf spot Ginger Soft rot. Trichoderma spp. Many properties namely size of particles, possession of ssRNA, salt-labile nature of particles and a limited host range of this virus are similar to sobemovirus group [7] but it, serologically unrelated to several sobemoviruses including lucerne transient streak virus, cocksfoot mottle virus, sowbane mosaic virus, Solanum nodiflorum mottle virus, southern bean mosaic virus, velvet tobacco mottle virus and turnip rosette virus. The response to the Facebook post (Ginger Nanoparticles Could Be Inexpensive, Nontoxic IBD Treatment) that I shared in 2017 was incredible!Researchers at the Atlanta VA Medical Center revealed that nanoparticles derived from fresh ginger root may be an effective treatment for Crohn’s Disease and Ulcerative Colitis. Later, the spots developed as white papery center and dark brown margins surrounded by yellow halos [125]. However, states namely Karnataka, Orissa, Assam, Meghalaya, Arunachal Pradesh and Gujarat together contribute 65 per cent to the country’s total production. Non-volatile and volatile compounds from T. viride inhibit the growth of P. myriotylum [58]. The plants which are infested by the disease stand persistently and do not collapse. Growing the ginger under the partial shade of mandarin orange increase the growth of the plant and reduce the disease intensity [135]. Plant disease-free ginger by using pathogen-free seed. Moreover, most of the known activities of ginger components are based only on in vitro and in vivo studies, except for a … Fights Germs. 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]. Ginger crop is being affected by insect pests, and pathogenic and non-pathogenic diseases cause production constraints. Sprouts, roots, developing rhizome and collar region of the pseudo stem are highly prone to infection. as well as improve the yield of ginger [89]. Soft rot is a complex disease problem and various methods should be applied to combat the disease. 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]. Similarly, dipping in garlic extract (20% w/v for 30 min) also reduces the disease incidence [152]. 3. Learn more about the importance, transmission, diagnosis, and control of plant diseases. zingiberi differed in their aggressiveness [99]. The secondary spread of the disease can also take place through irrigation water and by mechanical means. No obvious symptoms occur on the rhizomes. Leaf spot disease is becoming increasingly important in many places of India due to severe leaf rot and blight it causes. The fingers are severely affected by this nematode. It causes extensive damage to cortical tissues of root. Ginger leaves are occasionally damaged by grasshoppers. India is the leading producer and exporter of ginger in the world. Ginger is cultivated in most of the states in India. 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. Application of 0.3% Ridomil MZ during the storage condition causes the low infection [107]. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Kadam et al. In Himachal Pradesh, India none of the tested material of ginger was rated resistant to P. zingiberi, however, eight lines showed moderate resistance [137]. Among the various diseases, soft rot, yellows, Phyllosticta leaf spot, storage rot, bacterial wilt, mosaic, and chlorotic fleck are important. 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). Morphological, cultural, pathological and molecular variability among F. oxysporum f.sp. The various chemicals have been shown promising result against the pathogen [105, 106, 107, 108, 109]. The disease is formed in both air black and sandy loam soil and losses upto 80 % of plants has been reported. 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]. [149] reported that mancozeb fungicides compared to carbendazim is best chemical to protect the rhizome for the longer period from the fungus infection. Under the laboratory condition, pycnidiospores and mycelia of fungi alive for 14 months [126] and spores remain viable in soil even at 25 cm depth for 6 months. 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. Due to the infection, rhizomes appear soft, brown, water soaked, rotten, and decay gradually [34] (Figure 3). Symptoms appear first on younger leaves. 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]. Srivastava [56] effectively managed P. aphanidermatum by drenching Zineb or Mancozeb in the soil after treating the rhizome with carbendazim. Its antiinflammatory ability may be helpful in arthritis, cancer prevention, prostate disease, and general inflammatory processes. Management: The disease can be controlled by spraying Copper oxychloride 0.25 % or Mancozeb 0.2%. Pests and Diseases in Ginger Farming:- a) Pests found in Ginger farming: Shoot Borer: Symptoms: The symptoms It prepares holes in the pseudo stem. 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]. Mycelial growth in the form of white, peach or buff colored cushions can be seen on the surface of rhizomes [93]. GCFV is mechanically transmitted only to ginger but not like ginger mosaic virus, transmitted by Myzus persicae, Pentalonia nigronervosa and Rhopalosiphum maidis or R. padi. Ginger is being cultivated in the various parts of the world. It is widespread and exceedingly destructive for the ginger grows in tropical, subtropical and warm temperate regions of the world. Spraying 0.1% malathion at monthly interval from July to August will check out this. In the field the disease is observed one month after transplanting. The virus infected ginger possesses spherical particles with a diameter of 23–38 nm. Excessive liming or abundant coral sand in the soil may cause yellowing of the blades and poor growth. of diseases and it is believed that Si creates a physical barrier which can restrict fungal hyphae penetration, or it may induce accumulation of antifungal compounds. Treatment resulted in increased rhizome production with reduced yellows. The base of the infected pseudostem and the rhizome emit foul smell. 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. Armillaria root rot Armillaria mellea = Armillariella mellea Armillaria heimii = Armillaria fuscipes. Roots and rhizomes exhibit galling and rotting. 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. The plants perform best when planted in a light, well draining, organic loam with a pH between 6.0 and 7.0. Erwinia chrysanthemi is the only Erwinia species responsible soft-rot of ginger. Kumar et al. xanthi, 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). 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. Harvey and Lawrence [72] believed that crop rotations reduce Pythium spp. Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. Major problems of Ginger crop growing. We are a community of more than 103,000 authors and editors from 3,291 institutions spanning 160 countries, including Nobel Prize winners and some of the world’s most-cited researchers. 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]. Maximum disease incidence occurred when soil temperature ranged from 24 to 25°C and the soil moisture from 25 to 30% [104]. Mancozeb and carbendazim together treatment on ginger rhizomes protect the rhizomes from the rot [146, 147]. The immune system defends our body against invaders, such as viruses, bacteria, and foreign bodies. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Sowing of trap crops such as sorghum, maize and onion reduce the white grub infestation. They were analyzed by the unweighted pair group method with arithmetic averaging using randomly amplified polymorphic DNA amplicons. Fungus is the next major pathogen causes rhizome rot, soft rot, Sclerotium rot and yellows disease. Harrison special, N. tabacum var. 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. Using disease-free seeds is an essential step to prevent the contamination of Pythium [41]. Login to your personal dashboard for more detailed statistics on your publications. Severity of disease is influenced by high rainfall and when rhizomes planted in heavy clay soil with poor drainage. It is also soil and seed-borne disease. Leaf roller is caused by Udaspes folus (Figure 9). in height,. Drake G. N. 1995. F. solani is the second most important species [96, 98]. Ginger Root: Zingiber officinalis. Ramakrishnan [125] reported this disease first time from Godavari district of Andhra Pradesh and Malabar area of Kerala. High temperatures, saturated soils and injury during seed preparation all tend to exacerbate the disease. Bird's eye spot Cercoseptoria ocellata = Cercospora theae Pseudocercospora theae = Septoria theae = Cercoseptoria theae. Infected pseudo stem comes off from the rhizome with a gentle pull. China, India, Nepal and Thailand are the major producers of ginger in the world. 85% of the rhizomes possess the mold growth of Penicillium brevicompactum [143]. Two cultivars: SG 666 [121] and Kerala local [122] are reported to have disease resistant. 87 A study of the effects of ginger found that no subjects with vertigo taking ginger experienced nausea after caloric stimulation of the vestibular system, in contrast to those taking placebo. Symptoms: this disease mainly affects the radial leaves of transplanted seedlings at 3- 4 leaf stage during late March and early April. The plant grows well in cool weather but will tolerate a range from 9–28°C (48.2–82.4°F). Fungal diseases; Anthracnose Colletotrichum theae-sinensis = Gloeosporium theae-sinensis. Symptoms of spot on ginger leaf (source: Vikaspedia). It is an olive green caterpillar with a distinct black head. Advanced Medical Research. Ginger is utilized widely as a spice, for pickles, candies and as a medicinal herb. Diameter of gall is 3.3 cm. Applying organic manure, tillage and crop rotation reduces the yellows disease [76]. zingiberi isolates were studied by Gupta et al. Setty et al. 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. Symptoms : It is the most serious disease and the symptoms can be noticed form July-August. 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. Ginger benefits and side effects exist for your cardiovascular system. Other species of Fusarium such as F. solani (Mart.) Leaves of ginger are simple, alternate, linear-lanceolate, sheathing at the base, sessile, acuminate at apex, glabrosus, up to 15 cm.long. Immersing the rhizome in carbendazim (0.1%) for 60 min reduce the disease from 71.4 to 18.2% [112]. Biotic factors include virus, bacteria, fungus and nematodes [2, 3]. Reduction of soft rot occurred when seed was first disinfested with HOCl (1%) followed by soaking in Trichoderma spp. Botanical Facts. Certain chemical compounds in fresh ginger help your body ward off germs. Yellowing of leaves and oozing of rhizome due to bacteria wilt disease (source: Vikaspedia). The virus is transmitted by insect vectors such as Myzus persicae, M. certus, M. humuli, Macrosiphum euphorbiae and Rhopalosiphum insertum. [141], Cladosporium tenuissimum, Gliocladium roseum Bainer, Graphium album (Corda) Sacc., Mucor racemosus Fresen., Stachybotrys sansevieriae, Thanatephorus cucumeris (Frank) donk and Verticillium chlamydosporium Goddard [142]. The viral diseases of ginger are controlled in tissue cultures by heating at 50°C for 5 min [8]. Major problems of Ginger crop growing. From Australia, this virus is distributed to a number of countries which import ginger from Australia. The water mould can destroy rhizomes in 1-2 weeks. Diseases of tumeric (Curcuma longa L.) and their management. It differs from mosaic virus in particle properties, host range and serology. It is caused by the plant parasitic nematode, Meloidogyne sp. Virus isolated from affected ginger plants by So [4] named the virus as Ginger mosaic virus. Having soil solarization for longer periods reduces Pythium spp. Ginger is very easy to grow in containers. Talc-based formulations with rhizobacteria strain XXBC-TN (Bacillus subtilis) and a mixture of S2BC-1 (B. subtilis) and TEPF-Sungal (Burkholderia cepacia), inhibit F. oxysporum and F. solani. Of two major clusters formed, one was dominated by F. oxysporum and the other by F. solani. The pseudo stems from the infected plant can be easily separated with a gentle pull and can be broken off at the base. The affected pseudo stem and rhizome extrudes milky ooze from the vascular strands while they pressed gently. Tropical group native to India and Malaysia ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 127763-YjViZ Decomposition of soil amendments (dry or green crop residues, oil cakes, meals, sawdust, FYM etc.) diffusa (L.) Hook. It folds the leaves and stays inside the fold and defoliates the leaves from the tip and margins. Treating the plant with Bordeaux mixture, zineb and maneb are effective in treating the disease [132]. This presentation talks about the production, management, its disease, pest and their management/control practices. © 2019 The Author(s). Dichocoris punctiferalis cause shoot borer in the ginger (source: Ref. The best time to plant ginger is in spring. Phytosanitation is needed when the symptoms of soft rot appear in the ginger plantations. Ginger. Mild sunburn affects only the leaves, but acute sunburn damages the entire shoot [158]. Due to this, crop is severely affected without destroying the rhizomes. This chapter is distributed under the terms of the Creative Commons Attribution 3.0 License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Growing of resistant crops such as sunflower also checks the buildup of grub population. [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. Ralstonia solanacearum Yabuuchi causes bacterial wild disease in ginger. A manual on the most important pests and diseases of the major food crops grown by smallholder farmers in Africa. If you continue browsing the site, you agree to the use of cookies on this website. Indrasenan and Paily [79] identified Maran cultivar resistant against P. aphanidermatum. Strains from ginger in Hawaii showed less similarity for the strains from tomato (race 1) and heliconia (race 2) [18]. Poor drainage system and water logging increases the intensity of the disease. Post-harvest losses in ginger are a serious concern. Treating the rhizome with aureofungin (0.02%) and Benomyl (0.2%) before the Storage, control the disease [148]. Crop rotation with non-hosts such as graminaceous and a few antagonistic crops for 1 or 2 years reduces the nematode. 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]. 1. Chlorotic fleck in ginger is due to ginger chlorotic fleck virus (GCFV). Cortex of the rhizomes becomes lumpy and cracked during the severe infection. It is very difficult to control this. Ginger mosaic virus in standard extract is inactivated with 10 min exposure at 60°C [4]. Fungus like F. oxysporum Schlechtend ex Fr., P. deliense Meurs and P. myriotylum Drechs. is the best biocontrol agents for soft rot. India is considered as a ‘magical land of spices’ with diverse variety of spices. Soil solarization with biological control methods is beneficial to plant growth and antagonistic to many pathogens like fungi, bacteria, nematodes, and arthropods. Nageshwar et al.
