EINECS No.: 216-353-0
Application:
Carbofuran is a broad-spectrum, efficient, low residue and highly toxic carbamate insecticidal, acaricidal and nematicidal agent. It has the effects of internal absorption, contact and stomach toxicity, and has a certain egg killing effect. It has a long duration. Generally, the half-life in soil is 30 ~ 60 days. It can be used to control rice borer, rice thrips, rice leaf curler, rice planthopper, rice leafhopper, rice weevil, corn borer, corn root cutter, cotton aphid, cotton bollworm, soybean aphid, soybean heartworm, mites and nematodes. The general dosage is 6.8 ~ 10g active ingredient / 100m2, or 225 ~ 300g / 100m2 3% granules. In cotton seed treatment, cotton seeds can be depilated with sulfuric acid and then coated with 35% seed coating agent (the effective component is 1% of seed dry weight), which can control cotton aphids, ground tigers and other pests.
Health hazards:
The poisoning manifestations include salivation, tears, pupillary narrowing and muscle bundle tremor. However, compared with organophosphorus pesticides, the inhibition of cholinesterase lasted for a shorter time. After stopping contact, cholinesterase recovered rapidly.
