Problems solved by technology

[0002] Fruit trees, vegetables, wheat, potatoes, beans, melons and other crops are susceptible to diseases such as leaf mold, botrytis, early blight, scab, black bean, leaf spot, scab, leaf spot , although difenoconazole is widely used as a fungicide at present, there are still several problems as follows: 1. It has a good therapeutic effect mainly on leaf spot, powdery mildew, rust and scab; 2. Due to the use of It takes a long time, so it needs to increase the dosage to be effective, resulting in excessive pesticide residues in agricultural products; 3. In addition, due to long-term use, the above-mentioned diseases have developed serious drug resistance to difenoconazole, resulting in poor or even ineffective control effects
