In the present study, the biological control agent (BCA) Trichoderma harzianum strain Th4d was entrapped in biopolymeric compositions applied as film forming seed coat on oil seed crops viz., soybean, groundnut and safflower. Results revealed that high entrapment efficiency of 89- 92% with viability for 24 months without much reduction and persistence of Trichoderma in soil was studied which is having minimum spore count of 1X106 CFUs till 90 days of application in biopolymer-based Trichoderma seed coating treatment. Field evaluation of biopolymer-based Trichoderma seed coatings was done in soybean, ground nut and safflower exhibited higher productivity in biopolymer-based Trichoderma formulations over control.
