Low-toxicity nematode pesticide

Abstract

The invention relates to a low-toxicity nematode pesticide comprising the following components: 10-20 parts of cypermethrin, 5-8 parts of dibutyl citrate calcium naphthalene sulfonate, 2-7 parts of xylene, 5-20 parts of common threewingnut root, 10-25 parts of Indian quassawood extract liquid, 12-22 parts of aromatic hydrocarbon liquid, 5-10 parts of ferrous sulfate, 20-25 parts of kerosene, and 20-40 parts of water. The pesticide also comprises 2-10 parts of tetramethrin. The pesticide comprises 15-20 parts of the Indian quassawood extract liquid. The low-toxicity nematode pesticide provided by the invention is suitable for various vegetable, melon, and fruit crops. With the pesticide, dosing frequency can be reduced, yield can be increased, melon and fruit sweetness can be improved, and cost can be saved. The pesticide has good practical value.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a nematode insecticide with low toxicity. Background technique [0002] Plant parasitic nematodes are important pathogens among crop pests. In addition to directly causing plant diseases, nematodes can also spread a variety of pathogenic microorganisms. Global crops have suffered great losses due to plant parasitic nematodes. In China, nematodes are very serious. In general, they can reduce the output of vegetable crops, melons and fruits, and harm getting worse. Due to the rapid expansion of the area of ​​vegetables in protected areas in China, uninterrupted planting throughout the year has resulted in a large accumulation of nematodes and other pathogenic microorganisms, resulting in reduced vegetable production, affecting vegetable quality and exports, and seriously threatening the production of protected area vegetables.
