Analytical study on In vitro efficacy of fungicides against Colletotrichum capsici (Syd.) Butler and Bisby, causing anthracnose of chilli using CRD design

Abstract

Chilli [Capsicum annuum L.] crop is being affected by several fungal, bacterial, viral and nematode induced diseases. However, Anthracnose, caused by Colletotrichum capsici (Syd.) Butler and Bisby has been common occurrence, causing quantitative as well as qualitative losses in chilli. Therefore, present in vitro study was planned in CRD in vitro, in eight treatments replicated thrice, to assess the efficacy of fungicides against Colletotrichum capsici, at the Department of Plant Pathology, College of Agriculture, VNMKV, Parbhani (MS). Results revealed that, all of the eight (03 systemic, 03 contact and 02 combi-products fungicides (each @ 500, 1000 and 1500 ppm), evaluated in vitro were found fungistatic and exhibited significant mycelial growth inhibition of C. capsici, causing Anthracnose of Chilli. However, the fungicide (T2) Propiconazole 25% EC (92.62%, 100% and 100%) was found to be most effective there by inhibiting the maximum mycelial growth, followed by fungicide (T7) Azoxystrobin 18.2% + Difenoconazole 11.4% SC (89.44%, 94.44% and 100%), each @ 500, 1000 and 1500 ppm, respectively.
