Malathion ——High efficiency and low toxicity organophosphorus contact insecticide

Malathion, also known as marathon and 4049 marathon, is a highly effective and low toxic organophosphorus contact insecticide, which has strong internal absorption, good contact killing, stomach toxicity and certain fumigation. After contacting pests, the agent quickly enters the insect body through penetration and oxidizes into malathion, so as to quickly play its toxic role, Generally, pests can be knocked down a few minutes after application of the pesticide to effectively control the spread of locusts. Malathion enters warm blooded animals and is hydrolyzed by carboxylesterase, so it loses toxicity. The toxicity to warm blooded animals such as human body and livestock is very low and the residue period is short. It has become the first choice for locust control. The toxicity of malathion decreased when the temperature was low, and the dosage or concentration of malathion could be appropriately increased; Chewing mouthparts and stinging mouthparts pests; Contact killing and gastric toxicity, certain fumigation and penetration; Strong knockdown force against pests and good effect at high temperature; Short residual period; Sorghum, melons, beans, pears, grapes, cherries and other varieties are prone to drug damage and should be used with caution; Stop 10 days before fruit picking.

Main characteristics of malathion

Good quick effect: Malathion has a strong penetration effect. After contacting the agent, the pests quickly penetrate into the pests and can knock down the pests in 3 ~ 5 minutes, making the pests lose their flying ability. And finally kill pests.

Wide range of prevention and control: Malathion is mainly contact and stomach toxic, and has strong permeability. Therefore, it can be used not only to control Chinese locust, desert locust and other pests, but also to control yellow striped beetle, locust, aphid, long white scale, weevil, mirid bug, rice planthopper, thrips, leaf cicada, sticky insect, heartworm, bridge building insect and other pests.

Low toxic residue: Malathion is oxidized into malathion after entering the insect body, so as to play a toxic role. However, it is hydrolyzed by carboxylesterase in human and animal bodies and loses its activity. Therefore, malathion is only highly toxic to insects and low toxic to humans and warm blooded animals. Little impact on the environment. Malathion can be hydrolyzed as well as photolysis. Malathion remaining in soil is mainly degraded in water through biological pathway and hydrolysis. Its half-life in soil is 4 ~ 6 days and has little impact on the environment.

Cheap price: Malathion is produced on a large scale through chemical synthesis, with fast production speed and low cost. Compared with the biological insecticides currently used, malathion is more convenient for large-scale production, very cheap and can be used on a large scale.
