Pull out the diseased plant and take it out of the field.
Second, chemical control:
When the diseased leaf rate in the field is 1% to 5%, spray with 20% triadimefon EC 1000 to 1500 times, or 12.5% ​​diniconazole wettable powder 1500 to 2000 times, and then control it once every 7 to 10 days.
1. Triazolinone: Triadimefon is a triazole fungicide with high efficiency, low toxicity, low residue, long duration, and strong absorbability.

2. diniconazole: also known as speed Poly; triazole fungicide is a broad-spectrum fungicide that protects, treats, and eradicates; works on fungal cell membranes, thereby acting as a bactericidal agent, and has a long duration of efficacy. For humans and animals, beneficial insects, and environmental security.

In addition to alkaline substances, it can be mixed with most pesticides. It has the functions of protection, treatment, eradication and other bactericidal effects on diseases, and it has internal absorption and upward conduction. The pesticide application process avoids contaminating the skin; the medicament should be stored in a cool, dry place; after the application, the growth of a few plants is inhibited.
Precautions:
(1) It cannot be mixed with alkaline pesticides; it should not be used for a long time and should be used interchangeably with other types of fungicides;
(2) It is necessary to strictly control the concentration of use. When the dosage per unit area is too large, it is easy to inhibit the growth of cucumbers and zucchini; (3) It should be stored in a dry, ventilated, cool place. Http://
