Cypermethrin, an orchid insecticide

Also known as an Lubao, Xingmianbao. Brown-yellow viscous liquid, non-volatile, easy to dissolve in water, strong lipophilicity, stable to light, heat, acid and neutral solution, and easy to decompose in case of alkali. It has the functions of contact killing, stomach killing and anti-feeding. The application range and control object are similar to cypermethrin, but the effect on mites is poor, and the activity of cypermethrin is lower than that of deltamethrin, so the dosage should be 3 / 4 higher than deltamethrin in order to achieve the same effect. It has low toxicity to humans and animals, strong lethality to fish, bees and silkworms, safe to plants and little pollution to the environment.

Dosage form: 10% EC, 25% EC, 5% EC.

Prevention and control objects and usage:

L. Mainly control leafhopper, thrips, aphids and other pests. It is generally sprayed with 2500 to 3500 times liquid.

2. The borer should be sprayed during hatching or 1-2 days before hatching in order to achieve good results.

Note:

1. Cypermethrin has no internal absorption, so it is required to spray evenly and thoughtfully.

2. It should not be mixed with alkaline pesticides.

3. Cypermethrin has poor acaricidal power, such as when it is used to control mites, it must be mixed with acaricides.

4. Cypermethrin is toxic to natural enemies, so attention should be paid to it.

5. This medicine has irritating allergic reaction to the skin of some people, so pay attention to protection when using it. (Liu Zhongjian)
