Insecticides

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.

Chlorfenvinphos is the common name of an organophosphorus compound that was widely used as an insecticide and an acaricide. The molecule itself can be described as an enol ester derived from dichloroacetophenone and diethylphosphonic acid. Chlorfenvinphos has been included in many products since its first use in 1963. However, because of its toxic effect as a cholinesterase inhibitor it has been banned in several countries, including the United States and the European Union. Its use in the United States was cancelled in 1991. The pure chemical is a colorless solid, but for commercial purposes, it is often marketed as an amber liquid. The insecticides, mostly used in liquid form, contain between 50% and 90% chlorfenvinphos. The substance easily mixes with acetone, ethanol, and propylene glycol. Furthermore, chlorfenvinphos is corrosive to metal and hydrolyzes in the environment. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.
