Dark brown necrotic lesion is observed in nematode infected rhizomes. 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. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Reduction of leaf spot and sun burn on leaves occurred while growing plants under shade have increased the number of tillers per clump recommends the growing of ginger in partial shade to avoid the fungicidal spray [107]. Treatment resulted in increased rhizome production with reduced yellows. In: The Agronomy and Economy of Turmeric and Ginger: The Invaluable Medicinal Spice Crops. Increased yield of rhizome and decrease disease incidence was found while treating the rhizome and doing foliar spraying with Bordeaux mixture (1%), Companion (0.2%), Indofil M-45 (0.25%), Unilax (0.2%) and Baycor (0.05%) [129]. Diseases of Ginger (Zingiber officinale) in Hawaii. The incidence of the disease is severe in ginger grown under exposed conditions. Tsang and Shintaku [26] reported that bacterial wilt pathogen is eliminated when the rhizome is exposed to heat for 30 min at 50°C and 45 min at 49°C, respectively. It was first described by Simmonds [90] from Queensland. [28] observed that streptomycin and streptopenicillin are superior over the other antibiotics against the bacterial wilt pathogen. xanthi, N. tabacum var. Soft rot is a complex disease problem and various methods should be applied to combat the disease. [83] found that only 7% of the accessions have the relative resistance to the Pythium sp. 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. (2013b) studied genetic variability of 32 Fusarium isolates from diseased ginger rhizomes from Western Himalayas in India. The virus is transmitted through the sap to different plants which are believed to the hosts of CMV [4]. These small lesions merge and rot the rhizome. Major problems of Ginger crop growing. Seed solarization at 47°C for 30 min within a polyethylene sheet is ideal for Pythium sp. 8. Thomas [6] from Australia reported the chlorotic fleck in ginger is because of ginger chlorotic fleck virus (GCFV). Ginger plantation is majorly affected by deuteromycetous group of fungi cause variable symptoms [31]. Looks like you’ve clipped this slide to already. The moth lay eggs on the growing bud, petiole or leaf of the young plants. Disease cause significant losses during warm and humid conditions. Senapati et al. The disease is spread mainly through contaminated rhizomes. Growing the crop under the partial shade reduce the severity of Phyllosticta leaf spot. With a Master of Laws (LL.M) in taxation, Ginger is uniquely capable of providing families and businesses with tax-sensitive estate planning and administration. Treating with Burkholderia cepacia and T. harzianum showed production efficiency of 84% with reduction of disease incidence of 79.7% [67]. (Figure 8). Initially, water soaked patches or linear streaks appear at the collar region of the pseudo stem and then progresses both upwards and downwards. Ramakr. 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. Among the biotic factors, bacteria are most important, causes wilt and soft rot. Sacc., F. equiseti (Corda) Sacc., F. graminearum Schwabe, F. moniliforme Sheld and some unidentified Fusarium spp. Leaf roller is caused by Udaspes folus (Figure 9). The Diseases of Ginger. Decomposition of soil amendments (dry or green crop residues, oil cakes, meals, sawdust, FYM etc.) Drake G. N. 1995. Hasnat et al. 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. Drought and lack of water may cause the same effects as sunburn. Leaving the land fallow for 2 consecutive years reduce the pest population. In: The Agronomy and Economy of Tumeric and Ginger: The Invaluable Medicinal Spice Crops. SIBO & GINGER. The present chapter includes the symptoms, causative agent, disease cycle, epidemiology and host resistance, cultural, biological, chemical, and integrated management of these diseases. Incidence of disease is higher and yield of rhizome is reduced when the ginger is cultivated continuously without the rotation of the crop [131]. Insect involved in spreading the pathogens responsible for the diseases and also involved in damaging the foliage and rhizomes. The water mould can destroy rhizomes in 1-2 weeks. 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. Maintain the field sanitation and application of Bacillus thuringiensis (1–2 g/l) prevents the leaf roller. zoospores germination and spreading. Maximum disease incidence occurred when soil temperature ranged from 24 to 25°C and the soil moisture from 25 to 30% [104]. Dr. Sudhakar Kokate 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]. [159]). The spots increase in size and coalesce to form larger lesions which lead to the reduction of effective photosynthetic area on the leaves. It also by planting in well-drained soils, rotating susceptible plants with non-susceptible plants. Shoot borer caused by Dichocoris punctiferalis (Figure 7). In the advanced stage, infected ginger exhibit intense yellowish and wilting symptoms (Figure 2). CorporateComplexSimplicity - Presenters should always have a story as a presentation backbone. It is one of the commonly consumed dietary condiments in the world and has high medicinal properties. Nematode infections aggregate the fungus and bacterial infection. More than 87% of the seed pieces germinated without adverse effect on growth. The plants which are infested by the disease stand persistently and do not collapse. In the infected plants, leaf sheaths look yellowish to dull green. Leaf spot disease is becoming increasingly important in many places of India due to severe leaf rot and blight it causes. How? Page 409-426. Planting the disease free rhizomes is the best method to manage the disease [71]. Affected pseudo stem becomes water soaked and the rotting spreads to the rhizome resulting in soft rot. and their management. Leaves of ginger are simple, alternate, linear-lanceolate, sheathing at the base, sessile, acuminate at apex, glabrosus, up to 15 cm.long. [77] reported that neem seed cake with least average mortality (20.3%) followed by poultry manure (22.7). Native to South eastern Asia is used in dishes as delicacy, medicine / spice. Ginger is very easy to grow in containers. Among the various diseases, soft rot, yellows, Phyllosticta leaf spot, storage rot, bacterial wilt, mosaic, and chlorotic fleck are important. Biotype III from India causes the wilt in ginger [11]. Ginger. Diseases: Ginger is prone to several diseases, some of which may cause heavy losses. 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. Source-TamilNadu Agritech Portal . Symptoms Wilt is observed in patches. The most effective way to prevent this disease is simply keeping sanitary growing 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 … See our Privacy Policy and User Agreement for details. Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions. Rakesh et al. are major nematodes cause significant loss to ginger. Ginger (Zingiber officinale Roscoe) is a member of the Zingiberaceae family of plants. The grubs are creamy white and live in soil. The immune system defends our body against invaders, such as viruses, bacteria, and foreign bodies. 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. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. Nageshwar et al. The rhizomes of Zingiber officinale Roscoe (Zingiberaceae), commonly known as ginger is an important kitchen spice and also possess a myriad health benefits. The mycelial growth was inhibited at 5 and 35°C [127]. The rot that occurs on ginger is typically a wet weather disease, influence by heavy rains after planting. Reaction of ginger germplasm to Phyllosticta zingiberi. Sometime, the eggs laid on the decaying flower stalk, develop into larva, reaches the rhizome and reduce the quality of rhizome [160]. Seit 1585 prägt sie den Wissenschaftsstandort Graz und baut Brücken nach Südosteuropa. Elsevier Inc. Trujillo E. E. 1964. Cortex of the rhizomes becomes lumpy and cracked during the severe infection. 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. 3. Ginger Skinner enjoys providing expert advice and personable service to her clients to address their personal and corporate legal needs. Diabetes. The larvae apparently feed on decaying plant material; pupation occurs in the soil. Immersing the rhizome in carbendazim (0.1%) for 60 min reduce the disease from 71.4 to 18.2% [112]. Isolates of F. oxysporum f. sp. Ginger crop is being affected by insect pests, and pathogenic and non-pathogenic diseases cause production constraints. Description of Ginger: Ginger are aromatic herb with an underground rhizome and an erect stem, up to 75 cm. 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]. Researchers think ginger may help protect the liver, but this remains uncertain. During storage, rhizomes soft are affected by fungi [71] and bacteria. Nematode produces root knot disease and virus’s causes mosaic and chlorotic fleck in ginger plants reduce the yield of the rhizome. It is seed and soil borne disease carried by two ways: (1) Through diseased rhizomes scales [40] and (2) through soil as oospores. 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]. 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. Ginger has been used to treat nausea, vomiting, motion sickness, and vertigo. Biotic factors include virus, bacteria, fungus and nematodes [2, 3]. Serological relationship and electron microscopic observation of this virus conclusively suggested that ginger mosaic virus could be the CMV group. It causes extensive damage to cortical tissues of root. High temperatures, saturated soils and injury during seed preparation all tend to exacerbate the disease. It has been a part of healing strategies in Asia, India, Europe, and the Middle East for Due to the infection, rhizomes appear soft, brown, water soaked, rotten, and decay gradually [34] (Figure 3). Growing of resistant crops such as sunflower also checks the buildup of grub population. Disease is not found in well-drained soils. In the field the disease is observed one month after transplanting. HeadquartersIntechOpen Limited5 Princes Gate Court,London, SW7 2QJ,UNITED KINGDOM. The leaves of infected plants show chlorotic flecks, 1–10 mm long on the centered and parallel to the veins (Figure 1). 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. However, losses still occur in the Plot. ), (Figure 10) is pale reddish-brown and has nocturnal feeding habits. 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]. Director PPRC, India Sprouts, roots, developing rhizome and collar region of the pseudo stem are highly prone to infection. Crop Pests and Diseases. Bacterial wilt of ginger is the most serious rhizome-borne diseases. The favorable conditions like wet soil conditions, high soil moisture and soil temperature influence the development of the oospore [41]. She often works with her clients’ advisors such as financial planners and accountants. It can be produced in many countries but it does best in moist, tropical conditions. Ginger: Zingiber officinale is quoted as "World's healthiest food". Nematode feeds rhizomes, roots and base of the pseudo stems. Pests and diseases of ginger abound in Sikkim. Nelson [16] observed that the host range of race 4 of biovar III of R. solanacearum is restricted to edible ginger. J. of Spices & Aromatic Crops 4: 40-48. It affects roots and rhizome severely. Among different species of Fusarium, F. oxysporum causes decaying of ginger rhizomes [36]. zingiberi isolates with DNA amplification fingerprinting (DAF) segregated the isolates into three haplotypes based on 17 polymorphic bands generated with five primers [100]. Infected plants show yellow leaves with less number of shoots and stunted growth. Nematodes in the soil increase the incidence of wilt in ginger [15]. It also improved fatty liver disease and high triglycerides in rats by “turning off” fat-producing liver genes [40, 41]. 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. Mild drooping and curling of leaf margins of lower leaf is the first prominent symptom occurred after the infection, then the infection spread upwards later. 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. (otitid scavenger fly) and sciarid gnat fly. Using disease-free seeds is an essential step to prevent the contamination of Pythium [41]. Eleven species of Pythium are responsible for the soft rot diseases in ginger are identified so far. Diseases of Ginger, Ginger Cultivation and Its Antimicrobial and Pharmacological Potentials, Haiping Wang, IntechOpen, DOI: 10.5772/intechopen.88839. However, states namely Karnataka, Orissa, Assam, Meghalaya, Arunachal Pradesh and Gujarat together contribute 65 per cent to the country’s total production. Later, chlorosis from the older leaves progress to younger leaves start developing a similar symptom progression until the entire plant dies [35] (Figure 3). Risk factors for complications of GERD include advanced age, male sex, white race, abdominal obesity, and tobacco use. zingiberi differed in their aggressiveness [99]. The available physical, chemical, biological, methods and cultural practices to manage this pathogen are discussed below. Inflorescence a spike on a distinct scape; flowers densely arranged, bisexual, irregular, each subtended by a persistent scarious bract. Setty et al. Using soil with higher clay content and lower pH, suppress P. zingiberum and F. oxysporum [45]. Management: Healthy rhizomes have been obtained. The bacteria started to feed liquids released from injured cells and multiply. The base of the infected pseudostem and the rhizome emit foul smell. Though entire plant is refreshingly aromatic, the underground rhizomes of this crop are valued as spice. [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. In some people, ginger can have mild side effects such as abdominal discomfort, heartburn, diarrhea, and gas. Inflorescence a spike on a distinct scape; flowers densely arranged, bisexual, irregular, each subtended by a persistent scarious bract. Ginger and its polyphenols have been shown to target multiple signaling molecules that provide a basis for its use against multifactorial human diseases. 2.1 Key Oral Health Benefits of Ginger. Yellowing starts from the lower-most leaves which gradually progresses upwards. Hawaii Agricultural Experiment Station, University of Hawaii. Page 409-426. 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]. Kumar et al. Two cultivars: SG 666 [121] and Kerala local [122] are reported to have disease resistant. Genetic variation of F. oxysporum f.sp. Diameter of gall is 3.3 cm. 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. A reduction of production costs by elimi nating diseases would make Hawaiian ginger more competitive in the market. In Indonesia, the race 1 of biovar III is responsible for bacterial wilt in ginger [14]. Several species of Pratylenchus namely P. brachyurus, P. coffeae, P. indicus and P. zeae are infecting ginger. Grass is thrown out of the holes and central shoot becomes yellow and withers. None of the 18 cultivars tested in Karnataka, India were resistant to Phyllosticta leaf spot [136]. Consult these CTAHR publication for more information: 1) "Producing Bacterial Wilt-free Ginger in Greenhouse Culture" (2004); 2) "A Simplified Method of Multiplying Bacterial Wilt-Free Edible Ginger (Zingiber officinale) in … Control measures:. Verma and Vyas [134] observed higher protection while spraying carbendazim (0.15%) and mancozeb (0.25%) and due to this higher yield also obtained. J. of Spices & Aromatic Crops 4: 49-56. Here are five diseases that ginger can help treat and prevent.. Stroke. M. Kosta had a career story to tell and asked me to illustrate it. Temperature of 23–28°C with intermittent rain favored the occurrence of this disease. [22] reported the complete genome sequence of R. solanacearum SD54, a race 4 biovar 4 (R4B4) strain from a diseased ginger plant. 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]. Plants may show a premature drooping, wilting, yellowing, drying in patches or in whole bed and show stunting. Infected pseudo stem comes off from the rhizome with a gentle pull. Senapati and Sugata [81] found one resistant cultivar and eight others with moderate resistance while screening 134 ginger varieties available in Koraput, Orissa, India. Identifying Pythium resistant ginger is an ideal for effective soft rot disease management. 85% of the rhizomes possess the mold growth of Penicillium brevicompactum [143]. 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. The virus is transmitted by insect vectors such as Myzus persicae, M. certus, M. humuli, Macrosiphum euphorbiae and Rhopalosiphum insertum. This is not considered as a major problem in ginger, but periodic outbreaks occur when ginger is planted in waterlogged soil [12]. Singh A. K. 2000. These include Eumerus marginatus (Grims) (syrphid fly), Euxesta quadrivittata (Macq.) Symptoms: this disease mainly affects the radial leaves of transplanted seedlings at 3- 4 leaf stage during late March and early April. [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. 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. Rotting of roots is common. Excessive liming or abundant coral sand in the soil may cause yellowing of the blades and poor growth. Built by scientists, for scientists. The symptoms of root knot are very similar to root gall. 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. Mild sunburn affects only the leaves, but acute sunburn damages the entire shoot [158].
