Studies on the Efficacy and Management of Seed Borne Diseases and its Economics in Chickpea (Cicer arietinum L.)

Abstract

Background: Seed borne diseases are regarded as major constraints in chickpea production. Seed diseases are caused by biotic factor like fungi and abiotic especially by drought, resulted in decrease in seed yield and productivity. Hence studies on the efficacy and management of seed borne diseases and its economics of seed production in chickpea was attempted. Methods: The field experiment was carried out in Regional Agricultural Research Station, College of Agriculture, Vijayapur during rabi 2021-2022. The field experiment consisted eight treatments of fungicides and bioagents and combi- product of fungicide and bioagents viz., T1: Carboxin 37% + thiram 37% DS @ 2 g/kg of seeds, T2: Carbendazim 25% + mancozeb 50% WS @ 3.5 g/kg of seed, T3: Thiophanatemethyl 45% + pyraclostrobin 5% FS @ 4 ml /kg of seeds, T4: Seed treatment with Pseudomonas fluorescens @ 10/kg of seed, T5: Seed treatment with Trichoderma harzianum @ 10/kg of seed, T6: Seed treatment with Bacillus thuringenesis @ 10/kg of seed, T7: Seed treatment with Trichoderma harzianum @ 10/kg of seed + carbendazim 25% + mancozeb 50% WS @ 3.5 g/kg of seed T8: Control (without seed treatment) were used to study the efficacy of treatments on growth yield and economics and per cent incidence against R. bataticola in field condition. Result: Among the seed treatments carbendazim 25% + mancozeb 50% WS @ 3.5 g/kg of seed recorded significantly higher growth, seed yield, seed quality parameters and reduced per cent disease incidence and higher economics followed bythiophanatemethy 45% + pyraclostrobin 5% FS @ 4 ml/kg of seeds, as compared to control.
