In agricultural production, it is inevitable to use pesticides, how to choose pesticides, how to control pests at low cost and high efficiency, is not a very simple thing. What is the insecticidal range of cypermethrin? What are the issues to be aware of?
Cypermethrin, also known as kung fu permethrin, high efficiency cypermethrin and cypermethrin trifluoride, is a pyrethroid insecticide, a wide range of insecticides, resistant to rain erosion, for lepidoptera, coleoptera, diptera, tauroptera, orthoptera, hemiptera and mite pests have a good control effect, insecticidal toxicity is 4 times higher than cypermethrin, 8 times higher than cypermethrin.
Cypermethrin has an inhibitory effect in the early stage of mite occurrence, and when the number is large, the effect is not good. It can be used as a pesticide for insect mites and cannot be used as a special acaricide. Cypermethrin is ineffective against eggs and can be mixed with acaricides to control mites.
Cypermethrin is mainly used in food crops to control pests such as wheat field aphids, corn borers, armyworms, and rice leafminer flies.
Cyfluthrin can control soybean heartworms, soybean aphids, pod borers and bean borers.
Cypermethrin can be used to control cruciferous vegetables such as aphids, twill moths, kale moths, beet moths, tobacco moths, vegetable borers and greenhouse whiteflies, etc. In some areas, small cabbage moths have developed resistance and can not continue to use cypermethrin.
Cypermethrin can control fruit tree aphids, citrus leafminers, borer shell insects, jujube trees, pears, apple moths, small leaf curl moths, bag moths, pear small heartworms, peach heartworms and peach borer borers.
Cypermethrin can be used to control tea inchworm, tea caterpillar, thorn moth, tea moth and tea aphid
Cypermethrin can be used for parasite control in animals for the treatment of tobacco aphids and tobacco insects, and has a good effect on sanitary pests such as mosquitoes and flies.
1. Cypermethrin is mainly touch killing and gastric toxicity, there is no systemic effect, when spraying pesticides, be sure to spray in place to avoid reducing the use effect.
2. Cypermethrin has a disadvantage, that is, long-term use, pests will produce resistance, therefore, need to do experiments first, if resistance is generated, it should be replaced with other pesticides. Until resistance is developed, it is recommended to alternate between different pesticides to avoid resistance.
3. It cannot be mixed with alkaline pesticides, nor can it be used for soil treatment.
4. Cypermethrin is prohibited in paddy fields.
5. Cypermethrin is highly toxic to bees, fish and shrimp, and silkworms, and should be kept away from bee farms, fish ponds, rivers, and mulberry gardens.
6. Safe interval: 5 days for tomatoes, 7 days for leafy vegetables, 15 days for tea, 15 days for peaches, 21 days for food crops, 30 days for apples.
