To assess the effectiveness of fungicides against anthracnose disease of chilli in vivo

Abstract

Economic losses caused by the disease are mainly attributed to lower fruit quality and marketability which was losses of up to 100% under congenial environment conditions (Pakdeevaraporn et al., 2005). In India, a calculated loss of from 10-54 per cent has been reported (Lakshmesha et al. 2005) and 10-80 per cent of the marketable yield loss of chilli fruits reported by Than et al., (2008). Hence the present study is aimed to assess the status of anthracnose disease prevailing on chilli so that future strategies for crop protection are devised with a focus on anthracnose disease Average disease intensity recorded during study of field efficacy of fungicides were ranged from 46.63 (Propineb) to 70.23 (Propiconazole). However, significantly maximum average disease intensity was recorded with Propineb fungicide. This was followed by the treatments viz., Copper oxychloride Hexaconazole, Difenconazole, Tricyclazole, Tebuconazole, Azoxystrobin, Carbendazim 12% + Mancozeb 63% and Propiconazole.
