Abstract:
Cotton (Gossypium hirsutum L.) is one of the most important fiber crops playing a key role in the economic and social scenario of the globe. India is one of the major cotton growing countries in the world. India ranks first in area and second in the total production of cotton in the world. Cotton is grown worldwide for its natural fiber and oil. Cotton is primarily a raw material for a thriving textile industry and is also one of the most ancient and essential commercial crops, second only to food grains. In the present experiment, five different bioagents were screened in vitro for the growth inhibition of C. cassiicola by dual culture method, which inhibited the growth of pathogen by 65.55 to 80.97 percent. Among the Trichoderma isolates, T. viride followed by T. harzianum showed the most promising results compared to other isolates. The highest growth inhibition of C. cassiicola was recorded by T. viride (80.97%) followed by T. harzianum (76.25%). The least growth inhibition was recorded in T. fasciculatum (65.55%). B. subtilis (67.92%) and P. fluorescens (68.88%) were proved less effective as compared to fungal bioagents.
