Insecticide chlorpyrifos
2023-06-29

Introduction:Chlorpyrifos,chemically known as O,O-diethyl-O-(3,5,6- trichloro-2-pyridyl) thiophosphate, with the molecular formula C9H11Cl3NO3PS, is a white crystalline substance with a slight mercaptan odor. It is a non absorbable broad-spectrum insecticide and acaricide with high volatility in the soil.

Features: 1. It has a triple effect of gastric toxicity, contact killing, and fumigation, and has good control effects on various chewing and thrusting mouthparts pests on rice, wheat, cotton, fruit trees, vegetables, and tea trees.

2. The mixture has good compatibility and can be mixed with various insecticides with obvious synergistic effects (such as chlorpyrifos and triazophos).

3. Compared with conventional pesticides, it has low toxicity and is safe for natural enemies. It is the preferred agent to replace highly toxic organic phosphorus pesticides (such as 1605, methamidophos, omethoate, etc.).

4. It has a wide insecticidal spectrum and is easy to combine with organic matter in the soil. It has a special effect on underground pests and can last for more than 30 days.

5. No internal absorption effect, ensuring the safety of agricultural products and consumers, suitable for the production of pollution-free and high-quality agricultural products.

Note: 1. In the current prevention and control of brown planthopper, in order to improve the control effect, chlorpyrifos can be mixed with thiazide and pyraphid to enhance its contact killing, stomach toxicity, and fumigation effects on brown planthopper pests.

2. In the later stage of rice application, more attention should be paid to the adequate amount of spray. In the case of the recommended amount per mu, the amount should be increased or decreased with the spray solution. In the later stage of rice production, the upper limit of the recommended dosage should be more than 50 liters per mu for manual spray and more than 300 liters per mu for stretcher powered spray.

3. Comply with the regulations for safe use of pesticides and ensure proper labor protection.

4. In the mixed planting area of grain and mulberry, it is necessary to stay away from the silkworm breeding area and use medication with caution to avoid contamination of mulberry leaves and silkworm poisoning in rice fields.
