ABSTRACT

An in vitro experiment was conducted to evaluate the efficacy of different chemicals viz., tebuconazole + trifloxystrobin

75WG @ 0.05%, propiconazole 25 EC @ 0.1% and biocontrol agents viz., Trichoderma asperellum, Pseudomonas fluorescens, Bacillus subtilis on Rhizoctonia solani that causes banded leaf and sheath blight on barnyard millet. The chemicals were evaluated at the recommended dose, 50% of recommended dose, 25% of recommended dose and the results revealed that the growth of the pathogen was inhibited completely i.e., 100% and among the biocontrol agents Trichoderma asperellum was found to be more effective than Pseudomonas fluorescens, Bacillus subtilis. Trichoderma asperellum inhibited the growth of the pathogen upto 71.56%, while Bacillus subtilis and Pseudomonas fluorescens inhibited the growth of the pathogen upto 58.59% and 54.08% respectively.

 

KEYWORDS: Barnyard millet, banded leaf and sheath blight, chemicals, biocontrol agents.
