Fusarium wilt in chickpea (Cicer Arietinum L.) caused by Fusarium oxysporum f. sp. ciceris management through combination of Essential oils and bioagents

Abstract

Chickpea is one of the most important pulse crops contributes as largest producer in India with 75% of world acreage and production. Chickpea is grown in Rabi season. Chickpea is known to be infested by 172 pathogens (67 fungi, 3 bacteria, 80 nematodes and mycoplasma) from all over the world. Wilt of Chickpea caused by Fusarium oxysporum f.sp. ciceri is the most important disease, causing maximum economic damage to the crop. In the December month of 2018 to check the effect of seed treatment with bio-agents and essential oils against Chick pea wilt diseases to minimize the disease intensity. The treatments were Control (water irrigation), Neem oil 5%, Eucalyptus oil 5%, Trichoderma viride 5%, Pseudomonas sp. 5%, Neem oil 2.5%¬ + Trichoderma viride 2.5%, Neem oil 1.25%¬ + Trichoderma viride 1.25% + Pseudomonas sp. 1.25%, Neem oil 1.25%¬ + Trichoderma viride 1.25% + Eucalyptus oil 1.25% seed treatment was done. Among all the treatment in managing the wilt disease, Neem oil + Trichoderma viride + Pseudomonas sp. showed better results.
