Abstract

Freshly grown conidia of Trichoderma harzianum were suspended in oils along with 2% dextrose and vigorously agitated to find out its inhibition properties on uredospore and conidial germination of rust and late leaf spot. Paraffin oil + neem oil based formulation was most effective in inhibiting rust and late leaf spot causing organisms (87.08% and 91.76%, respectively) followed by neem oil based formulation (81.33 and 84.71% respectively).
