Eggplant has always been the main species of vegetable cultivation, but eggplant cultivation is often infested by powdery mildew. So, how to treat eggplant powdery mildew? At present, eggplant powdery mildew has two methods of agricultural control and drug control. Let's take a look down with Xiaonong.com.
Agricultural control
1 Eggplant seeds should be exposed to the sun for a day before sowing. Soak them in lime water for a day, soak them in water for half a day, and pick up the seeds. Or use a special accompanying seed medicine to plant seeds.
2 Remove the diseased eggplant stems left in the previous year, and the dry grass leaves around the vegetable fields. Remove the source of the disease.
3 Remove the wheat straw and McDull around the vegetable field to avoid the spread of wheat flour rust.
4 Eggplant should be deeped before planting and transplanting, and the deep soil should be turned over to reduce the bacteria.
5 clear the diseased leaves and reduce re-infection.
Drug control
Drug treatment should be very cautious, try to use pesticides with low toxicity.
1 Dilute 2500 times solution leaf spray with powder rust and bacteria.
2 with triadimefon plus chlorothalonil, diluted to 3000 times solution spray.
3 with methyl thiophanate plus chlorothalonil, diluted 3000 times solution with water spray.
4 with polysulfide plus carbendazim, diluted 3000 times solution with water spray.
Drug control should be carried out after lunch on sunny days and within 16 hours. The foliar absorption of the drug is fast and the effect is good. If it rains within ten hours, it will be sprayed immediately to prevent the disease from getting worse.
The above is the prevention and treatment method of eggplant powdery mildew organized by Huinong. In short, vegetable diseases are focused on prevention, pesticides are used as little as possible, pesticide residues are reduced or not, pollution is reduced, and efforts are made to achieve green safe and reliable food.
