Chlorpyrifos is a highly toxic insecticide, and it has a long residual time in the soil. Therefore, it should be taken care of when using it. Otherwise, it is easy to cause phytotoxicity. Let's follow it with Xiaobian.
1. Tobacco is more sensitive to chlorpyrifos and is prohibited.
2. The safety interval of chlorpyrifos for cotton, soybean, corn and wheat is 14 days; the safety interval of peanuts, hops and vegetables is 21 days; and the interval between rice and sugarcane is 7 days.
3. In the current prevention and control of brown planthopper, in order to improve the anti-effect, chlorpyrifos can be mixed with buprofezin (Pu Lingling) and Ruijinte to improve the contact, insect poisoning and fumigation of brown planthopper pests.
4. In the later stage of rice application, it is necessary to pay attention to the amount of spray. In the case of the recommended dosage per acre, the dosage should be increased or decreased with the spray liquid. In the later stage of rice, the upper limit of the dosage should be recommended. The sprayer of manual sprayer should be more than 50 liters per acre, and the sprayer of the stretcher-type motorized sprayer should be more than 300 liters per acre.
5. Observe the safe use of pesticides and do a good job in labor protection.
6. The grain and mulberry mixed plant area should be used away from the sericulture area to avoid the pollution of mulberry leaves and silkworm poisoning.
