Description

What is Chlorfenapyr

Chlorfenapyr is a new type of azole insecticide, acaricide and nematicide. It has contact and stomach poisoning effects, and has certain systemic effects. Its mechanism of action is by acting on the mitochondria of cells in the pest’s body. Block its oxidative phosphorylation and disrupt the energy production process in cells. Thereby the cell failure is achieved and the purpose of killing pests is achieved. The killing speed is fast and the duration of effect is medium.

Three major features of Chlorfenapyr

(1) Highly efficient and broad spectrum. Decarnitrile can control various pests such as cabbage caterpillars, cotton bollworms, leafminers, thrips, and vegetable aphids. It can be used for cruciferous vegetables such as Chinese cabbage, Chinese cabbage, cabbage, and kale. Melons, eggplants, pears and other fruit trees, as well as tea trees, poplars and other cash crops and forest trees. It is used to control pests and mites that are resistant to pesticides such as organophosphates, carbamates, and pyrethroids. It also has good effects.

(2) Good quick effect. Trichotoxic and contact poisonous effects on pests. It also has good permeability and certain systemic conductivity. It kills insects quickly and can usually kill pests within 1 hour after application. The peak of dead insects is reached in 24 hours, and the prevention efficiency reaches more than 85% on the same day.

(3) Good mixability. Difenfenil is a new type of azole insecticide and has no cross-resistance with mainstream insecticides currently on the market. It can be mixed or used alternately with emamectin, abamectin, indoxacarb, lufenuron, spinosad, methoxyfenozide and other insecticides.

Two major disadvantages of Chlorfenapyr

Although chlorpyronil has been on the market, it has performed well in controlling lepidopteran and other pests. However, due to reasons such as cost-effectiveness and resistance. It has also brought some adverse effects to the market promotion of fenfentrile, but the main reasons why many people are unwilling or afraid to use fenfentrile rashly are the following two aspects:
(1) It has no egg-killing effect. Acaronitrile can be used to control many types of pests such as Lepidoptera, Homoptera and harmful mites. It is especially effective against adults of lepidopteran pests, but it has no control effect on eggs. In actual use, this situation will occur. Existing pests may be eliminated quickly after application of pyrofenil. But in about a week, the eggs will hatch, and a new wave of pests will emerge, which will continue to harm crops. This also gives people the illusion that the insecticides treated by fenfonitril are “incomplete”.

The risk of drug injury is high.

Melon crops are sensitive to pyrofennitrile, and if used improperly, they are prone to phytotoxicity problems. For cruciferous crops, if pyrofenil is used before 10 leaves, macular damage is also likely to occur. This greatly increases the threshold for the use of fenfonitrile.
