Organic Management of Ascochyta Blight of Chickpea Caused by Ascochyta rabiei

Abstract

Organic management components viz., composts and organic formulations were evaluated against the Ascochyta rabiei under in vitro conditions. Four composts viz., Vermicompost, FYM, Sheep & goat manure and Poultry manure were evaluated against the pathogen at five different concentrations i.e. 5, 10, 15, 20 and 25 per cent using Spore Germination Method. Among composts, Vermicompost at 25 per cent test concentration was found best among all with 67.29 per cent inhibition of spore germination of A. rabiei followed by FYM (48.47%). Four organic formulations viz., Panchgavya, Jeevamrit, Beejamrit and Tamarlassi were procured from Department of Organic Agriculture and Natural Farming, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur and evaluated under in vitro conditions at 2, 4, 6, 8 and 10 per cent concentrations using Spore Germination Method. Among organic formulations, Jeevamrit at 10 per cent test concentration was found best with 89.16 per cent inhibition of spore germination of A. rabiei followed by Tamarlassi (33.13%), Panchgavya (32.51%) and Beejamrit (29.35%).
