What is the name of the pesticide that makes river shrimps dizzy?

There are many pesticides that can make river shrimps dizzy, the most common ones are pyrethroid pesticides, such as cypermethrin and so on. This drug, also known as diazinon, is a new type of pyrethroid insecticide with high efficiency, low toxicity and broad spectrum, which is particularly effective against Lepidoptera larvae and Homoptera pests. However, it is toxic to river shrimps. Therefore, once poisoning occurs due to pyrethroid pesticides, three methods can be used to detoxify: spraying baking soda throughout the pond, turning on the aerator, and changing the water.

The correct use of cypermethrin

1. Targets of prevention and treatment

It is mainly used to prevent and control agricultural pests, and has a good killing effect on many pests such as cotton bollworm, pink bollworm, cabbage worm, diamondback moth, fall armyworm, tobacco budworm, leaf-feeding beetles, aphids, blind tree species, stink bugs, leafhoppers, borers, leaf miners, spiny moths, caterpillars, loopers, bridge-building insects, armyworms, borers, locusts, etc.

2. Usage

Cypermethrin is mainly used for spraying to control pests, and sometimes it can be mixed with soil and spread as needed. Among them, the spray method is the most commonly used method of this medicine. If it is used in vegetable gardens, crops, and Chinese herbal plants, add 40-50 ml of 2.5% emulsion or 25 g/L emulsion or 2.5% microemulsion, 60-120 catties of water, and spray one acre of land. If used in orchards, tea trees, and flowers , use 1500-2000 times dilution of 2.5% emulsion or 25 g/L emulsion or 2.5% wettable powder or 2.5% microemulsion and spray evenly. If cypermethrin is needed, it can also be mixed with soil and spread.
