Evaluation of varieties and fungicides against anthracnose and fruit rot of Chilli

Twelve chilli genotypes were screened both in vitro and in vivo conditions to observe their disease reaction against anthracnose and fruit rot. Evaluation of chilli genotypes revealed that the genotype VNR-317 appeared to be moderately resistant, whereas four genotypes viz. VNR-333, 277, 10 and 315 were found moderately susceptible against fruit rot disease. Six fungicides viz. calixin (0.2%), copper hydroxide (XL-77 and XL-57) (0.3%), cholorothalonil (0.3%) and mancozeb (0.3%) were assessed to test their efficacy on growth, sporulation of Colletotricum capsici and development of fruit rot of chilli in vitro condition. Complete inhibition of mycelial growth of C. capsici was recorded by calixin, copper hydroxide (XL-77 and XL-57) and mancozeb. No sporulation of C. capsici was observed in calixin, copper hydroxide and mancozeb, whereas calixin, copper hydroxide (XL-77), copper hydroxide (XL-57) and mancozeb were highly effective to inhibit the disease development.
