The pathogenic effect of Trichoderma harzianum, T. viridae, T. pseudokoningii, T. aureoviridae, and T. glaucum on crops like rice, corn, pechay, tomato, and soybean was evaluated in the laboratory and greenhouse. Stunting and toppling down of affected seedlings caused by the Trichoderma spp. were observed on pechay and soybean but not on corn seedlings under the laboratory test. Under greenhouse test using sterile soil, pechay, and tomato seeds coated with T. harzianum and T. viridae, respectively, showed stem rotting. Stunting and yellowing of corn, tomato and pechay plants grown in soil with Trichoderma spp. were observed. On the other hand, improved growth was observed on soybean grown in soil with T. pseudokoningii and T. glaucum. Similar observation was noted on rice grown in soil with T. pseudokoningii
