Properties and stability
It is unstable in nature and will easily decompose and fail in the presence of sunlight, air, high temperature, moisture, alkaline substances, etc. Relatively stable under dry conditions
Storage method
Plastic bag sealed packaging. Store in a cool, dry and ventilated place. Do not store with food or feed. Keep away from children.
Synthesis method
1. Extract rotenone-containing plants with organic solvents, such as the roots of plants of the genus Rotenone, Buddleia or Gray Leaf, then concentrate the extract and filter it to obtain crystallized products.
Purpose
1. This product is a selective insecticide and acaricide that can be used on rice, vegetables, and fruit trees to control aphids, cotton spider mites, sawflies, etc. No harmful effects.
2.Under light, rotenone is easily oxidized into dehydrorotenone and loses its insecticidal activity. Mainly used for vegetables, fruit trees, tea trees, flowers and other crops to control various aphids, mites, stink bugs, melon flies, cabbage exigua, Spodoptera litura, thrips, yellow-striped flea beetles, yellow cucumbers, twenty-eight-spotted ladybugs, Tea caterpillars, tea loopers, etc. can also be used to prevent and control sanitary pests such as mosquitoes, flies, fleas, lice, etc.
