Abstract:
Cotton (Gossypium spp.) is the most versatile and important fibre crop next to food grains and grown throughout the tropical and sub-tropical regions of the world. Globally, cotton is known as ‘White Gold’ and ‘King of Fibers’ and it has immense importance in providing basic raw material to textile industries. The anthracnose disease caused by Colletotrichum gossypii is becoming serious threat for cotton production. In current study, in vitro efficacies of five biological control agents were examined during year 2021 against C. gossypii. The radial growth was recorded minimum (31.16 mm) in the Petri plate inoculated with Trichoderma harzianum followed by Trichoderma viride (36.17 mm), hence providing mycelium growth inhibition of 65.37 and 59.81per cent, respectively as compared to untreated control. Pseudomonas fluorescens was found least effective and 50.63 per cent mycelial growth inhibition was recorded, however the radial growth of 44.43 mm was observed as maximum among all tested antagonists.
