Abstract

Organic enriched composts viz., himcompost, vermicompost, farm yard manure, poultry manure and NADEP and organic formulations namely cow urine, beejamrit, panchgavya, tamarlassi, vermiwash and biosol were evaluated against Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris under in vitro conditions. Among all the organic formulations, Panchgavya showed maximum mycelial inhibition of 92.22 per cent followed by Biosol i.e. 72.22 per cent at 10 per cent concentration against the pathogen whereas, Tamarlassi was found least effective with 15.56 per cent mycelial inhibition. The extracts of all five organic composts showed antifungal properties against the pathogen even at 5 per cent concentration. At 25 per cent concentration Himcompost yielded maximum mycelial inhibition of 71.11 per cent followed by Vermicompost i.e. 65.27 per cent against the pathogen whereas, NADEP was found least effective i.e. 44.17 per cent inhibition. Hence, Himcompost and Panchgavya can be used as soil amendment and seed dresser, respectively for ecofriendly management of Fusarium wilt of chickpea.

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%).
