The common name of Qingtaijing is promethazine, and its main component is 4,6-diisopropylamino-2-methylthio-s-triazine. It is a gray powder with a slight pungent odor. It is a selective systemic and conductive herbicide, which can be absorbed from the roots, or penetrated into the body from the stems and leaves, and transported to the green leaves to inhibit photosynthesis, and the poisoning weeds gradually become dry and die due to chlorosis. Promatogin's selectivity is related to the differences in plant ecology and biochemical reactions, and it has the best control effect on newly germinated weed moss.
Dosage: Dilute with more than 300 times of water, evenly splash or spray, 0.18-0.26 grams per 1 cubic meter of water, 116-175 grams per acre of water depth of 1 meter; the amount can be appropriately increased locally for places where moss grows concentratedly. One cubic meter should not exceed 0.35 grams, that is, the product should not exceed 234 grams per acre of water with a water depth of 1 meter. Once a day Use for 1-2 days
Precautions for use: ①Do not use with other drugs at the same time; ②Prohibited in hypoxic waters; Prohibited in rainy days; ③Promptly increase oxygen for more than 3 hours after using this product; ④Use the drug on sunny days and when the algae has just grown, the effect is best; ⑤Algae After death, it should be taken out in time, and the water should be changed appropriately; ⑥Use with caution when aquatic animals are in the nursery and seedling period, and when shrimps and crabs are about to shell out or concentrated shelling; ⑦When the water temperature is lower than 20℃, the dosage can be increased appropriately. However, it should not exceed 0.4 mg/L; ⑧If there are too many algae, the area used at one time should not exceed one-third. ⑨ Use caution when there are aquatic plants in the pond; ⑩ Destroy the packaging after use.
Limojing kills moss quickly and thoroughly, and is widely used.
The trade names of Promatojing's fish medicines are: Rongzaojing; Mizaojing; Kezaoling; Mizaoling; Taizaojing and so on. When buying medicine, pay attention to choosing whether the main ingredient is promethazine.
When using, you must pay attention to immediately remove the dead algae, change the water in time, re-fertilize the water, and cultivate the microalgae. Many industrial households killed the moss with medicine. Due to the inability or neglect to change the water in time, the decay of dead algae polluted the water quality and caused a large number of deaths of sea cucumbers, shellfish and other cultured products.
[Storage] shading, sealed, and stored in a dry place at room temperature.
