Mass multiplication of biocontrol agent Chaetomium brasiliense using different substrates under South Gujarat condition

Abstract

Agricultural substrates were used for mass multiplication of Chaetomium brasiliense (C2). Experiment carried out in laboratory condition where significantly higher spore population was found in pigeonpea stalk (55.00 c.f.u/g) followed by paddy straw, sugarcane trash, sorghum stalk, sugarcane stalk, FYM and cotton stalk. Least sporulation was observed in wheat straw (30.67 c.f.u/g). C. brasiliense population was gradually increased up to 30 days of inoculation and then it was decreased within 60-90 days.
