Effect of fungicides on the production of amylase by Rhizopus oryzae.
Seven fungicides (Brassicol), captan, Dithane M-45, Fytolan, Parasan, Sulfex and Thiram) were tested for their effect on the production of amylase enzyme by Rhizopus oryzae. The activity of amylase was determined by cup-plate method. All the fungicides were found inhibitory for the synthesis of amylase. Out of these, Parasan was the most effective causing hundred percent inhibition at 0.025% concentration. No amylase production was recorded when Thiram, Fytolan, Brassicol, Captan and Dithane M-45 were used at 0.5, 1.5, 2.0, 2.0, and 2.0% concentration respectively. Sulfex was found to be less effective, as hundred percent inhibition of amylase production has not been recorded even at 3.0% concentration.
