BIOCONTROL POTENTIAL OF TRICHODERMA VIRIDE AGAINST MAJOR FOLIAR DISEASE OF SOYBEAN (GLYCINE MAX L.) UNDER IN MID HILL CONDITIONS OF HIMACHAL PRADESH INDIA

Soybean (Glycine max L.) is a major leguminous oil seed crop with high in vegetable protein and oil. It is the third most important oil seed of India after mustard and groundnut. The current study entitled “Biocontrol potential of Trichoderma viride on Soybean (Glycine max L.) in mid hill conditions of Himachal Pradesh” was carried out at Agriculture research farm in 2023 and 2024 at Abhilashi University. The results indicated that in year 2023, minimum Septoria brown spot disease incidence (12 %) was recorded in T4 (Seed treatment with Trichoderma viride @ 10 g / kg of seed + Mustard cake @ 1-2 kg/hectare). The results indicated that in year 2023, minimum Cercospora leaf blight disease incidence (9.2 %) was recorded in T4 (Seed treatment with Trichoderma viride @ 10 g / kg of seed + Mustard cake @ 1-2 kg/hectare). Similarly, results indicated that in year 2024, minimum Cercospora leaf blight disease incidence (12 %) was recorded in T4 (Seed treatment with Trichoderma viride @ 10 g / kg of seed + Mustard cake @ 1-2 kg/hectare). Similarly, results analysis for the year 2024 indicated that minimum pod blight disease incidence (10.4 %) was recorded in T4 (Seed treatment with Trichoderma viride @ 10 g / kg of seed + Mustard cake @ 1-2 kg/hectare). Whereas, maximum disease incidence (24 %) was recorded in T7 Control.
