Usage of avermectin in aquatic products

Avermectin is used to kill insects. There are two types of avermectin, which can be used in plants and aquatic products. What is the method of using aquatic avermectin?

I. usage of aquatic avermectin

1% avermectin diluted with water 2000 times and sprinkled evenly throughout the pool. The water depth is 1 meter per mu, and each bottle of 100ml can use 4-6 mu. To control red insects, use 8-10 mu per bottle of 100ml.

Introduction of aquatic avermectin

Avermectin is a white or yellowish crystalline powder or yellowish solution, which is a new type of broad-spectrum, high-efficiency and low-toxic antibiotic antiparasitic drugs. the killing effect of avermectin is to increase the release of the inhibitory transmitter r-aminobutyric acid (GABA). And open the glutamate-controlled Cl- channel to enhance the permeability of the nerve membrane to Cl-, thus blocking the transmission of nerve signals, resulting in nerve paralysis, losing the contractile ability of muscle cells and leading to the death of worms. 0.3%, 0.5% and 1% avermectin solutions are commonly used in the market. Used to kill all kinds of fish, shrimp, crab, shellfish and other monoculture and mixed culture ponds and proliferating water bodies and parasitic parasites on the body surface of fish, such as Anchor head, Chinese mackerel, fish fish, nematodes, ring worms, third-generation worms, pine algae worms, water centipedes and other aquatic insects.

Matters needing attention of aquatic avermectin

1. It is forbidden to use before and after hypoxia and floating head.

2. Increase oxygen for a long time after use.

3. When the water quality deteriorates, it is prohibited after flooding the pond.

4. Do not mix with disinfectants

5. Shellfish culture in tidal flat should be used with caution.

6. the use of seedlings should be halved.

The use of avermectin needs to be calculated according to water quality and product content, not blindly.
