Uses:Malathion is a contact insecticide popularized nationally in 1980 for insect control (malathion), which has a good touch killing effect on maize, wheat, sorghum and many other grass crops, especially the major pest of rice, Chinese rice locust, and malathion can also be used to control vegetable yellow streak skipping, aphids, forest tree locusts, fruit tree pentatoms, aphids Many pests such as tea tree Landrace, weevil, cotton cecropism, aphid, rice planthopper, thrips, leaf cicada, wheat slime worm, aphid, legume heartworm, bridge forming insect. In recent years, there have been registries on malathion products
Product Application:Malathion crude drug is a superior crude drug, which can compound with other crude drugs and play a good synergistic effect. It can be made as a single agent or compounded with various pesticides such as avermectin, phoxim, dichlorvos, Fenvalerate and deltamethrin to form series products.
Product Feature:Malathion has good contact, gastric toxicity and a certain fumigant effect without internal absorption. Into insects it oxidizes to malaoxon, thereby being more virulent, whereas into warm blooded animals it is hydrolyzed by carboxylesterases not found in the insect body, thus losing its toxicity. Malathion has low toxicity, short residue duration and is effective against pests of chewing mouthparts.
Packing:250kg / barrel (also available upon customer request).
Malathion (also known as marathon) is a parasympathetic insecticide made of organic phosphorus. It will irreversibly combine with cholinesterase and has low toxicity to humans. In the former Soviet Union, this chemical is called "carbophos", in New Zealand and Australia as "maldison", and in South Africa as "mercaptothion". It is an over-the-counter pharmaceutical product in Hong Kong. Malathion is highly volatile and has low toxicity to humans and animals. As long as it is placed in a ventilated place, its toxicity will be reduced immediately. Marathon pesticides will be dispersed into the environment when they are manufactured and used in large quantities. If the spraying process falls into the soil, the marathon will combine with the soil and will be hydrolyzed quickly without polluting the groundwater source.
