Benzoylphenylurea insecticides
1. Chlorobenzuron: It has special effects on Lepidoptera larvae and can be used to control armyworms, rice leaf rollers, bean hawk moths, cabbage armyworms, cabbage worms, pine caterpillars and other pests. It can also control some sanitary pests, such as mosquitoes and fly larvae. The effective period is more than 30 days. After the larvae ingest chlorobenzuron, their activities become slow, their feeding decreases, their bodies turn black, and their epidermis becomes thinner, affecting normal molting.
2. Diflubenzuron: Low-toxic specific insecticide. It has stomach poison and contact killing effects, but no systemic effect. It has special effects on Lepidoptera and Diptera pests. Diflubenzuron is the first chitin synthesis. It can be used for pest control of various crops, and can effectively control pests that are resistant to organophosphorus and organochlorine.
3. Flufenuron: Flufenuron has good leaf retention, especially high activity against mites and pests. It is widely used on citrus, cotton, grapes, soybeans and corn. It is effective against herbivorous mites and many other pests, and safe against predatory mites and natural enemy insects.
4. Lufenuron: The latest generation of urea-replacing insecticide. The agent kills pests by acting on insect larvae and preventing the molting process. It has excellent prevention effects on leaf-feeding caterpillars such as fruit trees, and has a unique killing mechanism for thrips, rust mites and whiteflies. It is suitable for controlling pests that are resistant to synthetic pyrethroids and organophosphorus pesticides. For leaf rollers, night flies, apple rust mites, codling moths, etc., 5 grams of active ingredients can be sprayed on 100 kg of water. For tomato armyworm, beet armyworm, flower thrips, tomatoes, cotton bollworm, potato stem borer, tomato rust mite, eggplant fruit borer, diamondback moth, etc., 3-4 grams of active ingredient can be used to spray 100 kg of water. When using, pay attention to alternate use with other pesticides such as kulon, hysteromycin, and avermectin.
5. Novaluron: Novaluron is an insect growth regulator and a chitin synthesis inhibitor. It has excellent effects on the eggs and nymphs of whiteflies and is safe for parasitic wasps. It will be another important pesticide for the control of whiteflies. It is used to control lepidoptera, coleoptera, hemiptera and diptera larvae of whiteflies and leafworms in various crops such as fruits, vegetables, cotton and corn. Through ingestion and contact behavior. Prevent normal molting and kill pests.
6. Triflumuron: It is mainly a stomach poison and contact killing effect, inhibiting the synthesis of insect chitin, causing the larvae to molt, unable to form a new epidermis, and the insect body to die due to deformity. Due to its high efficiency, low toxicity and broad spectrum, it can be used to control coleoptera, diptera, and lepidoptera pests on corn, cotton, forests, fruits, and soybeans, and is harmless to natural enemies. It is mainly used to control Lepidoptera and coleoptera pests such as golden moth, cabbage worm, diamondback moth, wheat armyworm, pine caterpillar, etc. The control effect is more than 90%, and the efficacy period can reach 30 days.
Nereistoxin insecticides
1. Cartap: It has systemic, stomach poison and contact killing effects, and is particularly effective against Lepidoptera larvae, Hemiptera, and Homoptera pests. It is used to control rice, vegetable and fruit tree pests. Cartap is converted into nereis toxin in the insect body and acts on the acetylcholine receptors of the insect central nervous synapse. It has a long residual effect and is toxic to humans and animals.
2. Monosultap: Monosultap is a monosodium salt: it can effectively prevent and control rice stem borer, rice stem borer, rice leaf roller, and has good control effect on rice leafhoppers, lice, rice budworms, fruit tree aphids, etc. Monosultap is sensitive to cotton and certain beans and cannot be used on such crops.
3. Bisultap: Bisultap has stomach poison, contact killing and systemic effects. It has special effects on rice stem borer and rice leaf roller, and has good control effect on many fruit tree and vegetable lepidopteran pests. It can be sprayed, poisoned soil and root zone application.
4. Thiocyclam: Thiocyclam is a selective insecticide with stomach poison, contact and systemic effects. It can be transmitted to the top. The effective period for controlling Lepidoptera and Coleoptera pests is 7-14 days. It can also control parasitic nematodes, such as rice white tip nematodes, and has a certain preventive effect on rust and white spike disease of some crops. It can control yellow stem borer, rice leaf roller, striped stem borer, rice thrips, leafhoppers, rice gall midge, planthoppers, peach aphids, apple aphids, apple red spiders, pear star caterpillars, citrus leaf miners, vegetable pests, etc.
5. Bensultap: It has stomach poison, contact and systemic effects. It is used to control rice stem borer, yellow stem borer, diamondback moth, potato weevil, grape spike moth and other Lepidoptera and Coleoptera pests, especially for rice pests. The effective period is longer.
