Abstract: The control targets of 200 million CFU/mL HNI-1 suspension concentrate were tomato root-knot nematode and tomato mosaic disease. For tomato root-knot nematode control, root irrigation was carried out when tomatoes were transplanted. 200 million CFU/mL HNI-1 suspension concentrate was applied 2—3 times per crop season, with the dosage of 400—600 mL/667 m2. The application period for tomato mosaic disease was chosen before or at the early stage of the disease. HNI-1 was sprayed 2—3 times per season, with the dosage of 180—240 mL/667 m2. HNI-1 is pure biological preparation, and no drug harm has been found after application. There is low toxicity or no effect on predators and parasitic predators.
