High-efficiency, broad-spectrum organophosphate insecticide - chlorpyrifos, has contact, stomach poisoning and fumigation effects on pests, especially for the control of brown planthopper. The relevant application technologies are introduced as follows:
First, the product features:
1, chlorpyrifos 蜱 domestically there are emulsifiable concentrates, granules, microemulsions and other dosage forms. Among them, 40.7% emulsifiable concentrate (the same Shun, Le Siben) has the highest content; most of them are 40% emulsifiable concentrate (Xinongbao, chlorpyrifos, Bole), the most used in the use of emulsifiable concentrate, the effect is good; 5% of granules are mainly used for The prevention and control of underground pests of vegetables and melons is an excellent variety to replace the highly toxic pesticide 3% furan granules; 30% microemulsion is being gradually promoted.
2. Chlorpyrifos is a poisonous pesticide. It is highly toxic to fish and aquatic organisms. It is toxic to bees. The residual period on leaves is generally 5-7 days, and the residual period in soil is longer. It has no phytotoxicity to most crops, but is sensitive to tobacco and tomato leaf spray.
3. In the current 5th generation of brown planthopper eggs or in the field where the amount of insects is low, 25% buprofezin can be used plus 40% or 40.7% chlorpyrifos EC (Shun Shun, Xinnongbao, Bo Le, Le Siben) 80-100 ml / mu, or 5% Regent 30-40 ml / acre plus 40%, 40.7% chlorpyrifos EC 80-100 ml / mu spray. When applying the medicine, the field maintains a water layer of 2-3 cm. It has a high density of rice fields, and it is difficult to spray the liquid to the rice fields at the base of the rice. It is sprayed with a large-capacity sprayer. It is used for rice leaf roller and rice horses. 40.7% chlorpyrifos EC 80-120 ml per mu with a mist sprayer; for Plutella xylostella, Pieris rapae, soybean pests, 40.7% chlorpyrifos EC 80-150 ml fine spray per acre; for citrus leaf miner, red Spiders, tea mites and other pests, 40.7% chlorpyrifos emulsifiable concentrate diluted 1000-2000 times.
Second, matters needing attention
1. 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. 2. In the late stage of rice use, 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. 3. Obey the safe use rules of pesticides and do a good job in labor protection. 4, grain mulberry mixed plant area, should be careful to use drugs away from the sericulture area to avoid contamination of mulberry leaves and silkworm poisoning by rice fields.
