    Abstract


    The present experiment was conducted to determine the effectiveness of fungal antagonist formulations derived from Trichoderma viride (CP2, CP3 and CP4) in controlling some soil-borne fungal diseases of potato, ground-nut and soybean. The T. viride  was isolated from the soybean soils at Phu Thi – Gia Lam and some other locations.  For potatoes, tuber treatment  with 50 g CP2,  200g CP4 and mixed with 100 kg manures per 10 kg tubers  gave the highest control efficiency against southern blight disease (58.3%),  For soybean, spraying CP3 at a concentration of 15g in 3 litters  per 30 m2 at seedling stage gave good control efficacy after 21 days (75.5% for the damping-off  and 67.7% for the southern blight ). Peanut seed treatment with 5g CP3 or CP2 per kg seeds gave good control of damping-off disease (80,8% and 79.4%, respectively.  In field demonstration plots potato, soybean and peanut yield increased by 9.7% , 12.2 %. and 15.6 %, respectively in comparison with the control.
