Alphacypermethrin is a pyrethroid insecticide with high biological activity. It has wide insecticidal spectrum, fast knockdown speed, contact killing and stomach toxicity, and its insecticidal activity is higher than that of cypermethrin. Alphacypermethrin can be used to control pests on crops such as cotton, vegetables, fruit trees, tea trees, soybeans and sugar beets. It has good control effects on Lepidoptera, Hemiptera, Diptera, Orthoptera, Coleoptera, tasselwing and Hymenoptera on cotton and fruit trees. It has special effects on cotton bollworm, cotton red bollworm, cotton aphid, litchi stink bug and citrus leaf miner. It is suitable for controlling pests and sanitary pests on cotton, vegetables, fruit trees, tea trees, forests and other plants. It blocks the movement of proteins to axons by blocking the transmission of sodium ion signals from sodium ion channels at nerve endings to nerve impulses. Usually this poisoning leads to rapid knockdown and death. Alphacypermethrin is a non absorbable insecticide with contact killing and gastric toxicity. It acts on the central and peripheral nervous system at a very low dose. Nerve axon poison can cause extreme excitement, spasm and paralysis of insects, and produce neurotoxin, which can eventually lead to complete blocking of nerve conduction, and can also cause unexpected pathological changes of other cells and tissues of the nervous system and death. Alphacypermethrin has contact killing and gastrotoxic effects, no internal absorption, and acts on the central and peripheral nerves of insects at low doses. It has egg killing activity. Alphacypermethrin is a pyrethroid insecticide with high biological activity. It is composed of high-efficiency isomers of cypermethrin. Its insecticidal activity is about 1 ~ 3 times that of Cypermethrin, so the dosage per unit area is less and the effect is higher.
In order to prevent and control aphids of cotton pests, 5% alphacypermethrin missible oil 20 ~ 30mL (effective component 1 ~ 1.5g) per mu was used for spraying water, spraying 10d 1 times, spraying 2~3 times continuously to control aphids. During the incubation period, the cotton bollworm was sprayed with 5% alphacypermethrin missible oil 25 to 40mL (active ingredient 1.25 ~ 2.0g) per mu.
Control of soybean heartworm: Soybean sprout can be effectively controlled by spraying water with 5% alphacypermethrin missible oil 20 ~ 30mL (active ingredient 1 ~ 1.5g) during the peak period of adults. This method can also effectively control soybean leaf roller.
Control flower pests: The flower aphids of chrysanthemum and Rosa chinensis were treated with 5% alphacypermethrin missible oil 5000~10000 times or 100 L water plus 5% CIS cypermethrin 10 to 20mL (effective component 5 ~ 10mg/L).
