Evaluation of Bioagents against Fusarium oxysporum f. sp. pisi Causing Wilt Disease in Pea

Abstract

In this study, in vitro potential of six selected species of Trichoderma, including Trichoderma viride, Trichoderma virens, Trichoderma harzianum, Trichoderma longibrachiatum, Trichoderma ressei and Trichoderma asperellum as well as the of two bacterial isolates Pseudomonas fluorescens and Bacillus subtilis were evaluated against Fusarium oxysporum f. sp. pisi causing wilt of pea. Trichoderma virens recorded maximum percent growth inhibition (81.97%). In volatile compounds percent growth inhibition 86.80 % was recorded highest in Trichoderma harzianum and percent growth inhibition in non-volatile compound will increase as concentration of bioagents increases and 100% growth inhibition was recorded in Trichoderma viride, Trichoderma virens, Trichoderma harzianum and in Trichoderma ressei at 15% concentration.
