In vitro evaluation of fungicides against Fusarium oxysporum f. sp. ciceri

Abstract

Chickpea (Cicer arietinum L.) is one of the most important pulse crop grown all over India. Chickpea wilt caused by Fusarium oxysporum f. sp. ciceri is one of the major disease on chickpea in Northern Karnataka, which is soil and seed borne. Heavy inoculum in the soil and favorable environment condition results in the death of infected plant and therefore total yield loss. Experiment was conducted for selection of superior fungicides for the management of chickpea wilt disease, three combi product fungicides, three systemic fungicides and three non-systemic fungicides were evaluated against Fusarium oxysporum f. sp. ciceri in in-vitro condition with two concentrations each. Among the non-systemic fungicides copper oxychloride was effective in inhibiting the mycelial growth with 82.97% and 86.02% at 2000 and 3000 ppm concentration. Among the systemic fungicides carbendazim exhibited 79.81% and 82.03% inhibition of mycelial growth at 1000 and 2000 ppm concentration. Among the combi product fungicides Carbendazim12%+ Mancozeb 63% exhibited 100% inhibition of mycelial growth at 1000 and 2000 ppm concentration.
