Evaluation of fungicides against Gray mould (Botrytis cinerea Pers. Fr) and Leaf mould [Fulvia fulva (Cooke) Cif. (Cladosporium fulvum Cooke)] of tomato

Abstract

Gray mould (Botrytis cinerea Pers. Fr) and Leaf mould, [Fulvia fulva (Cooke) Cif. (Cladosporium fulvum Cooke)] are major disease of tomato causing significant yield losses under protected conditions. Twelve fungicides, including systemic, protectant, coformulations and bicarbonate salts were tested against mycelial growth of Botrytis cinerea and Fulvia fulva, at 25, 50, and 100 μg ml-1 concentration. Among the fungicides tested azoxystrobin + tebuconazole was found to be most effective showing complete inhibition of mycelial growth even at lowest tested concentrations for both the pathogens. Bicarbonate salts of sodium also gave cent percent mycelial growth inhibition of the pathogens
