CAO CHONG JING

[Characteristics] Yellow liquid.

[Product Features] Suitable for eliminating harmful aquatic insects in fish, shrimp, and crab culture ponds, with remarkable results.

[Main Functions]

1. Primarily used to remove chironomid larvae and dragonfly nymphs in shrimp and crab ponds, preventing their eggs from growing and reproducing in the water.

2. Effectively controls aquatic pests such as ciliates attached to aquatic plants, red worms (Chironomus larvae), aquatic earthworms, and “grass-eating insects” on aquatic plants in crab ponds, thereby protecting the aquatic plants and improving the survival rate of shrimp and crabs.

[Usage and Dosage] Dilute with water at a ratio of 1:3000, then evenly spray over the entire pond. For each mu (≈0.0667 ha) with 1 meter water depth, use 50–100 ml of this product (i.e., one bottle for 1–2 mu).

[Precautions]

1. Ensure the required dilution ratio is met and spray evenly.

2. Use with caution in the early stage after stocking fry.

3. For polyculture of different special aquatic species, conduct a small-scale trial first to determine a safe and reasonable dosage.

4. Use in clear weather; do not use in cloudy, foggy, rainy, or oxygen-deficient conditions.

[Packaging] 100 ml/bottle.
