Problems solved by technology

[0006] However, when pesticides are used alone or unscientifically for many times, the use period of pesticides may be prolonged, and the amount of use may be increased, resulting in high cost of use, which is not conducive to popularization and application in production.
For example, apple spot defoliation, cucumber downy mildew, etc. have developed resistance to some common pesticides, resulting in a decline in control efficiency and rampant diseases, which in turn lead to frequent application of pesticides, resulting in increased drug costs and aggravated environmental pollution.
[0007] In order to overcome the above-mentioned deficiencies in the prior art, the inventors have combined the characteristics of the two compounds through a large number of market research, formula screening, field drug efficacy tests, etc., and screened out a compound preparation of pentothiastrobin and polyoxin , and the compound pesticide composition and application of benzathystrobin and polyoxin have not yet been reported
