Antifungal Activity of Plant Products for the Management of Fruit Rot Infection in Chillies
S. Sundaramoorthy, S. Usharani and Ancy P. George

Abstract:
The efficacy of 13 plant products were evaluated against chilli fruit rot and dieback incited by Colletotrichum capsici. Among them bulbs of A. sativum (20%) and A. cepa (60%) and seed extract A. indica 60% gave complete inhibition of the pathogen and were on par with carbendazim (0.1%) leaf extracts of D. metel, E. globulus and P. juliflora at 60% concentration totally inhibited the mycelial growth of C. capsici. Conidial germination of C. capsici was completely inhibited by A. sativum 20%, E. globulus, D. metel 60% and P. juliflora 60%. Plant products at their respective MIC=s totally inhibited the sporulation of C. capsici. Production of cellulolytic and pectinolytic enzymes the pathogen was also inhibited maximum with fungicide carbendazim (0.1%), followed by A. sativum and E. globulus. The same treatments recorded maximum seed germination (17.74%), seedling vigour and maximum control of disease incidence. Pots treated with A. sativum (20% conc.) recorded higher yield and fruit characters such as increased fruit length (43.53 cm) and fruit weight (36.19 g).
