Chickpea (Cicer arietinum L), wilt caused by Fusarium oxysporum f. sp. ciceri is the most destructive disease in India and also first reported from India in 1918. It is seed-borne as well as soil-borne pathogen. The results concluded that Soil inoculation with Fusarium oxysporum f. sp. ciceri @ 100g/ plot of soil. Seed dressed with bio-control agents @ 4g/ Kg of seed and fungi-toxicants viz. neem leaf and neem bark powder @ 4g/ Kg of seed, bavistin and Thiram @ 3 g/Kg of seed. Observation of wilt incidence was recorded at 30, 60 and 90 DAS. Root length, Shoot length, Root weight and Shoot weight were also recorded at 30, 60 and 90 DAS. The wilt incidence was recorded minimum with Bavistin, Thiram and Trichoderma viride. The Shoot weight, Root weight, Shoot length and Root length was maximum when treated with Pseudomonas fluorescence (T3), Trichoderma viride (T2).
Like other crops, chickpea is also attacked by various diseases and insect-pests, out of which fusarial wilt and pod borer of chickpea are most severe; there are many methods such as breeding and cultivation of resistant varieties, use of chemical fungicides and insecticides for management of fusarial wilt of chickpea. However, increasing use of chemical fungicides and insecticides in plant protection results in several serious hazardous problems. Continuous uses of these chemical substances disturb our ecological equilibrium, result in increase of human diseases, problems of resistance in pests, pathogens and weed population. This problem can be minimized by using biological control agents under an integrated pest/ disease management programme. Therefore, in the present investigation, it was observed that application of bio-pesticide formulations in the laboratory, as well as in the field conditions showed significant performance in controlling wilt diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
