Among 1000 peanut soil samples were collected from Nghe An province, Thanh Hoa province and Ha Tinh province, 44.90% samples occurred Trichoderma. The appearance ratio of Trichoderma in Nghe An, Thanh Hoa, Ha Tinh is 44.30%, 52.00% and 39.50%, respectively. By using in the dual culture method on PDA, The Percent Inhibition of Mycelial Growth (PIRG) was determined to be very high in 28 Trichoderma strains (made up 28.3% in total), 29 others strains was dertermined that to be high PIRG (made up 29,3% in total). The highest PIRG was 100%, occurred on T. harzianum (Tri.019(4).NC; Tri.053(1).TG; Tri.011(1).NL; Tri.002(2).NX strain), T. atroviride (Tri.020(2).NC; Tri.011(1).NC strain), T. reesci (Tri.007(1).NĐ), T. hamatum (Tri.039(1).TG), T. virens (Tri.014(4).NC) and T. pseudokonigii (Tri.014(1).NL).
