Insecticides

Indoxacarb has a unique mechanism of action. It exerts its insecticidal activity through contact and gastric toxicity. Insects enter the body after contact and feeding. Insects stop feeding, dyskinesia and paralysis within 3 ~ 4 hours, and generally die within 24-60 hours after treatment. Indocarb has excellent insecticidal activity against almost all important agricultural Lepidoptera pests such as cotton bollworm, tobacco bud noctuid, Plutella xylostella, cabbage caterpillar, beet armyworm, pink armyworm, blue armyworm and apple bark moth, and also has certain effects on some Homoptera and coleoptera pests such as small green leaf cicada, potato leaf cicada, peach aphid and potato beetle.

Cartap is a toxin insecticide of sand silkworm, which has the advantages of high efficiency, broad spectrum, low toxicity and low residue. It has many functions such as internal absorption, stomach toxicity and contact killing. It invades the junction of nerve cells, blocks the acetylcholine secreted by the former nerve cell to transmit to the latter nerve cell, and makes the nerve cell not excited, makes the insect nerve paralyzed, unable to eat, unable to move, stops development, and even dies. It has good control effect on Chilo suppressalis and Chilo suppressalis, and can also control Cnaphalocrocis medinalis, leafhopper, armyworm, Plutella xylostella and Phyllotreta striolata.

Acetamiprid is a new insecticide, belonging to nitromethylene heterocyclic compounds. It acts on the nicotinic acetylcholine receptor at the synapse of insect nervous system, interferes with the stimulation conduction of insect nervous system, causes the blockage of nervous system pathway, and causes the accumulation of neurotransmitter acetylcholine at the synapse, resulting in insect paralysis and final death. It has contact killing and stomach toxicity, strong penetration, good quick effect and long duration. Acetamiprid can be used to control aphids, planthoppers, thrips, Lepidoptera and other pests in rice, vegetables, fruit trees and tea trees. At the concentration of 50 ~ 100 mg / L, it can effectively control cotton aphid, vegetable aphid and peach fruit borer, and kill eggs.

Methoxyfenozide is a new type of specific phenylhydrazide insecticide with low toxicity. It has high selective insecticidal activity against Lepidoptera pests, mainly contact killing effect and certain internal absorption effect. The agent belongs to biomimetic ecdysteroid insect growth regulator. After eating the agent, pests will produce molting reaction and begin molting. Because they can not molt completely, the larvae will dehydrate and starve and die. The action mechanism of the agent is opposite to that of the agent for inhibiting the molting of pests. It can be used in the whole larval stage of pests. It is mainly used for vegetables and farmland to control Lepidoptera pests on vegetables (melons, eggplant fruits), apples, corn, cotton, grapes, kiwi fruit, walnuts, flowers, sugar beets, tea and field crops (rice, sorghum, soybean).

Indoxacarb is an organochlorine insecticide.
