Anthracnose disease caused by Colletotrichum gossypii is an emerging problem of cotton. Present study was carried out to evaluate the efficacy of neo fungicides under in vitro and in vivo conditions against C. gossypii causing anthracnose disease of cotton during Kharif season of 2020 and 2021. Maximum growth inhibition was recorded with the fungicide Azoxystrobin 18.2% + Difenoconazole 11.4% SC (90.48%) followed by Metiram 55% + Pyraclostrobin 5% WG (84.57%). Minimum disease intensity was observed with the fungicide Azoxystrobin 18.2% + Difenoconazole 11.4% SC in cotton cultivars i.e. Bt (7.01%) and non Bt (8.20%) during the years of evaluation with maximum seed cotton yield of 2590 kg/ha and 2105 kg/ha, respectively. The results of this experiment reported that all the fungicides tested have great potential in managing anthracnose disease of cotton and recorded fruitful results as compared to untreated check.
