Cucumber powdery mildew, commonly known as "white disease", suffers the most from leaf damage, followed by petiole and stem, and generally does not harm the fruit.
At the early stage of disease, white or nearly circular small spots appear on the front or back of the leaves, gradually expanding into large areas of white powder with indistinct edges, and covered with foliage, as if a layer of white powder had been scattered. When the white powder is erased, the leaf surface is chlorotic and yellowish and brittle. When the disease is severe, the leaves are covered with white powder and turn grayish until the entire leaves die. After powdery mildew infects the petiole and tender stems, the symptoms are similar to those on the leaves. Only the lesions are smaller and the powder is less.
Prevention:
1. Selection of disease-resistant varieties: Generally, cucumber varieties resistant to downy mildew are more resistant to powdery mildew.
2, improve the cultivation and management: avoid excessive planting, base fertilizer increased phosphorus, potassium, pay attention to field drainage and ventilation. When powdery mildew occurs, small water can be poured between rows of cucumbers to increase air humidity. In combination with spraying, disease can be controlled in one fell swoop. Additional measures include avoiding over-application of nitrogenous fertilizers, increasing phosphorus and potassium fertilizers, and removing diseased tissues after pulling.
3. Disinfection of facilities: When planting indoors, before planting, use 250 grams of sulfur powder, 500 grams of sawdust, or 250 grams of 45% chlorothalonil smoke agent per 100 cubic meters of space. To kill the bacteria in the entire shed.
4. Chemical control: Before the onset of disease, spray 27% lipid membrane 100 times liquid to protect the leaves. During the onset of illness, 25% of triadimefon WP may be 2000 times wave, or 70% of thiophanate-methyl WP may be 500-800 times, or 50% of Suspension of Sulphur 300x, or 2% of VA Agent 200 times, or 20% antimycotic 200 times, or 12.5% ​​diniconazole 2500 times spray control. Spray once every 7 days, continuous control 2-3 times. In addition, 5% chlorothalonil dust can also be sprayed.
