Chlorfenapyr, the English name is Chlorfenapyr, the trade name is Chlorfenapyr, the Chinese common name is Chlorfenapyr. It is a new type of heterocyclic insecticide, acaricide and nematicide successfully developed by American cyanamide company. With the introduction of the national policy on the substitution of highly toxic pesticides and the improvement of people's awareness of environmental protection, as a representative of the recommended pesticide varieties for pest control of pollution-free agricultural products, the application of low-toxic and high-efficiency chlorfenapyr is more and more widely used.
A novel pyrrole insecticide and acaricide. It has excellent control effect on drilling, sucking and chewing pests and mites. It is more effective than cypermethrin and cyfluthrin, and its acaricidal activity is stronger than dicofol and tricyclic tin. The agent has the following characteristics: broad-spectrum insecticide and acaricide; both gastric toxicity and contact killing effect; no cross-resistance with other insecticides; moderate residual activity on crops; Selective systemic activity; moderate oral toxicity to mammals, low transdermal toxicity; low effective dosage (100g active ingredient/hm2). Its remarkable insecticidal and acaricidal activity and unique chemical structure have attracted widespread attention and attention.
Features
Tetranil, also called bromfenpyr, is an arylpyrrole compound that has stomach toxicity, certain contact effects and systemic activity to pests. It has excellent control effect on borers, piercing and sucking mouthparts pests and harmful mites, with a medium duration. Its insecticidal mechanism is to block the oxidative phosphorylation of mitochondria. The product is a 10% suspension concentrate.
Instructions
Chlorfenapyr has a certain effect of killing eggs. Combined with the prediction and forecasting of pests, it is recommended that spraying at the peak of the pest's incubation or the peak of egg incubation can have a good control effect.
Since chlorfenapyr has good local conductivity in the plant body, it can penetrate and conduct from one side of the leaf to the other side, so the same effect can be obtained on the back of the leaf that the pests feed on.
The control effect is 90-100% within 1-3 days after the medicine, and the medicine effect can be stabilized at 90% within 15 days after the medicine. The recommended dosage is 30-40 ml per mu, and the safety interval is 15-20 days.
Use 34-50 ml of 10% suspending agent to control the diamondback moth, beet armyworm, and mu on cruciferous vegetables, and spray 40-50 kg of water as a regular spray. The dosage should be increased for older large insects, and the efficacy can be maintained for about 15 days. It should not be used more than 2 times in each growing season. It can be mixed with cis-cypermethrin, or used in rotation with hexaflumuron or lambda-cyhalothrin to enhance the oviparison effect.
toxicity
It is highly toxic to fish and bees, so care should be taken to protect it when using it.
