Dimethoate
[Features] Dimethoate is an organophosphorus systemic insecticide with contact and certain stomach toxicity, no steaming effect; easy to be absorbed by plants and transported to the whole plant to be oxidized to higher toxicity in insects. The omethoate, its insecticidal mechanism is to inhibit the activity of acetylcholinesterase in insects, hinder the transmission of nerve information and lead to insect death. The insecticidal activity of the drug is significantly enhanced with the increase of temperature, and the temperature is below 15 °C. Poor effect, effective period of 5~7 days
