Abstract

Bakanae disease caused by Fusarium fujikuroi Nirenberg is one of the important diseases affecting the rice crop at different stages of the growth.  Twenty eight Trichoderma isolates were collected from the major rice growing areas of Nalgonda, Krishna and Khammam districts of Andhra Pradesh belonged to seventeen species. The isolates found effective invitro against the Fusarium fujikuroi for their antagonistic property in dual plate culture were selected to study for their ability to reduce growth inhibitory volatile and non-volatile metabolites against the pathogen.

Keywords

Antagonism Bakanae disease Fusarium fujikuroi Trichoderma.
