Insecticide, fungicide, acaricide, herbicide characteristics summary
It is 10-100 times more active than avermectin in killing insects, mites and nematodes, and has a wider insecticidal spectrum; stomach poisoning is the main effect as well as touching; irreversible paralysis of pests occurs, and they stop feeding and die only after 2-4 days, so the insecticide speed is slow; the duration of effect is long, 10-15 days for pests and 15-25 days for mites. No endosmosis in crops, but can penetrate into epidermal tissues; very active against lepidopterans, mites, coleopterans and coleopterans, thrips, and not easily resistant to pests; easily degraded in soil; highly safe for all crops in protected areas or at 10 times the recommended dose; a second peak of insecticide occurs in 10 days or more;
Nicotine; touch, stomach poisoning and internal absorption; pest paralysis and death; good fast-acting, high efficacy in 1 day, residual period up to about 25 days; good insecticidal effect at high temperature; stinging-sucking oral pests; easily absorbed by crops and distributed to the top, with root-sucking effect;
