Abstract

The present invention belongs to the field of microorganisms, and specifically relates to a Trichoderma strain antagonistic to melon root-knot nematode disease and wilt disease and its application. Trichoderma breve Application of HLST422‑7 in the control of root-knot nematodes and wilt diseases. Trichoderma breve There are no reports on the use of HLST422‑7 in the prevention and treatment of plant nematode diseases, and there has never been any relevant research on the combined infection of nematodes and wilt. T.short Compared with T069, Trichoderma breve HLST422‑7 has better control effects on root-knot nematodes and wilt, and can also improve plant growth in the presence of nematodes, further demonstrating the great advantages of this strain in plant disease prevention and control.
