Due to the recent low rainfall and high temperatures, the occurrence of cotton aphids has increased sharply, and the occurrence is significantly higher than the same period of last year. If there is continuous high temperature and little rain, the occurrence of cotton maggots will also increase, which will lead to the occurrence of a large number of blister defects. If the prevention and control do not take place in time, the cotton yield will be affected. Therefore, farmers must prevent and control in a timely manner and do a good job of preventing and controlling the damage.
1. Chemical control. 1 Spray with 3% acetamiprid or 10% imidacloprid EC 1000-1500 times; 2 spray with 2.0% MCC traceless EC 1000-1500 times; 3 use 30% DH vaccine 10,000-1.5 million times spray.
2. Note. 1 The cotton field should be used for prevention and treatment at one time. In regions where the locust occurrence is heavy, the dosage should be increased. The dosage should be repeated every 3-4 days. When taking medicine, it is necessary to make the liquid hit the back of the leaf so that the effect can be fully exerted. 2 do not mix and control the tapeworm when the tapeworm, because the aphid occurs serious plants, often smaller, more spray, the amount of shrinkage Ann large, the growth of plants is even more inhibited.
Fertilizer pump mounted directly on the pipe, the kinetic energy of pipe flow to drives the pump to work at a set ratio to suck high erconcentration drug or quantitative fertilizer in to the pump. After mixed with the water and delivered to downstream. No matter How to change the water pressure, Drug or fertilizer will be mixed and discharged according to a certain proportion.
