In order to increase the use of pesticides, some farmers’ friends have continuously increased their doses. “We are not afraid that the heads are not bad, we are afraid to add two pounds of charcoal”. In fact, this is only necessary when the pests have developed drug resistance, and the drug resistance problem requires specific analysis of specific drugs and cannot be generalized. In order to be efficient, safe, reduce pollution, and delay the development of drug resistance, I hereby propose the following five points, in which the correct diagnosis, symptomatic remedy, and enhanced predictions are the key to improving the effectiveness of pesticide use.

The first is the correct diagnosis, the right medicine. Correct diagnosis is the key again. Only when the diagnosis is correct can a reasonable countermeasure and choice of pharmaceutical agents be determined. On the other hand, it is also necessary to be familiar with the medicinal properties of various pharmaceutical agents and their targets for prevention and treatment. Correspond to each other, can be used.

Strengthen predictions and fight drugs in due course. All kinds of pests and diseases have a natural disaster process. Like a fire, they must be controlled in the early days. Once it becomes popular, prevention and control will become a “cannon of fire”. Moreover, no matter what pharmacy has a certain period of validity. Timely and timely drug use is the key to ensure the effectiveness of prevention and treatment. To do this, we need to constantly check the condition, pest situation and do a good job of forecasting.

Choose equipment, high quality and efficient. Because many fungicides mainly play a protective role, many insecticides rely on stomach poisoning and contact killing to kill pests, which requires that the agents spread evenly, not heavyly and without leakage. To this end, in order to achieve timely prevention and control, especially for large-scale prevention and control, it is necessary to continuously improve the spraying equipment and increase the degree of mechanization.

Accurate dispensing, application in place. Accurate dosage is the guarantee of efficacy, and it is difficult to eliminate the amount of the drug. The mistakes that often occur in the real world are that the unreasonable increase in the amount of drugs and the total amount of water is obviously insufficient.

Delayed resistance, mixed use. Pest resistance has become an important production issue. It is an adverse consequence of the continuous use of a single agent over a large area. The use of agents that alternately use or mix different insecticidal and bactericidal mechanisms will cause the control subjects to lose a stable direction of mutation and delay the improvement of resistance. This will not only improve the control of the farmland, but also help protect the pesticide resources.
