Although pesticides have been available for a long time, as an important type of pesticide processing, it has been a great development in research and application in the past 10 years. This is mainly due to the increasingly difficult development of new pesticides, pests. The problem of pesticide resistance is very prominent, and it is also developed in response to various needs in agricultural production. The main purpose of pesticide mixture development is very clear, summarized as follows:
1. Delay and control resistance
In order to reduce the field resistance of certain pesticide varieties with high risk of drug resistance, to delay and control the resistance of Cordyceps and to prolong the economical service life of pesticides, it is one of the important purposes of developing mixtures in recent years.
2. Broaden the scope of use of pesticides
With the advent of new pesticides, the mixture was developed mainly to broaden the use of the new pesticides to reduce the expensive price. At the same time, these mixtures are used in the prevention and treatment of those with reduced resistance frequency, which is undoubtedly prevention. A good way to entangle the resistance of textile objects.
3. Improve the efficacy
Because the Lange or multiple single agents in the mixture synergize with each other, the virulence and emulation of certain pesticides can be improved, and the dosage per unit area can be reduced, thereby reducing the cost and delaying the pest resistance.
4. Expand the target of prevention and treatment
The single machine in the mixture can complement each other and complement each other, and expand the spectrum and scope of use of the pesticide, which expands the use of the mixture.
5. Reduce the price and cost of certain pesticides
To reduce the price of certain pesticides and agricultural production costs. It is an effective method for pesticides that are very effective but are difficult for farmers to accept because of their high price.
6. Development of new uses for old pesticide varieties
7. To control certain objects, reduce the number of pesticides used to save labor and time, and configure the mixture to reduce the toxicity of certain pesticides.
8. Improve economic efficiency
Obtain significant economic and social benefits. On the basis of pesticide toxicology research, pesticide mixtures developed through strict technical and operational procedures can often achieve significant economic and social benefits.
