Management of Chickpea Wilt Incited byFusarium oxysporum f.sp. ciceri (Padwick) Snyder and Hansen

Chickpea (Cicer arietinum L.) is an important pulse crop, which belongs to family Leguminose. Chickpea wilt caused by Fusarium oxysporum f.sp. ciceri is one of the most important disease in India. Yield losses vary between 10 to 100% depending on varietal susceptibility and agroclimatic conditions. Considering, the importance of disease the present study was undertaken during, Rabi 2010–11. Pot culture experiment conducted at Department of Plant Pathology, College of Agriculture, Latur and field experiment was conducted in wilt sick plot at ARS Badnapur to asses fungicidal seed treatment on wilt incidence. Results revealed that all fungicidal applied as seed treatment, significantly reduced the wilt incidence in chick pea. However, Propiconazole (25% EC) was found most effective with significantly least wilt incidence (2.00%), followed by Penconazole (3.53%), Thiophenate methyl (3.66%), Hexaconazole (4.37%); while Kasugumycin was found least effective with highest (76.54%) wilt incidence.

Test pathogen inoculated soil using chickpea cv. JG-62 to evaluate the effect of different seed treatments wilt disease. Result revealed of pot culture experiment that seed treatment with Carbendazim + Thiram was most superior with least wilt incidence (16.63%), highest wilt control (80.49%), vigour index (1410.7) and dry matter (20.95g), followed by Carbendazim + SAAF, with wilt incidence of 17.43 per cent and wilt control of 79.80 per cent, over untreated control (86.56% wilt incidence). Among the soil amendments, minimum wilt incidence was observed with cotton cake (48.93%), followed by groundnut cake (59.16%). Of the bioagents, minimum wilt incidence was recorded with T. viride (29.67%), followed by T. harzianum (35.60%). Among the phytoextracts, Neem seed kernel extract recoded minimum wilt incidence (36.36%), followed by garlic bulb extract (47.93%).
