Cucumber cultivation requires attention

Farmers grow cucumbers most afraid of rotten vines (also known as rotten stems). Rotten vines mean that when cucumbers begin to produce a lot of melons, if they run into high temperature and high humidity, in just a few days, melon vines will wil the whole ridge, and there are obvious spots on the vines. Cucumber leaf blight is caused by the Ascomycete fungus, which not only harms stem vines, but also damages leaves and fruits. When the stem is attacked, it shows oily spots near the nodules, oval or prismatic, grayish white, slightly concave, secreting an amber fluid. When dry, the diseased part is shrunk longitudinally and a large number of small black spots are scattered on the surface. The lesions spread rapidly when wet, and the upper half of the plants wilted and died, and the diseased part rotted around the stem. The lesions on the leaves are nearly circular, sometimes "V"-shaped or semi-circular, pale brown to yellow-brown, with many small black spots on the lesions. The fruits were mostly infected by flower buds during the young period of melons, and the flesh was light brown and soft, showing heart rot. Seed carriers and soil carriers are primary sources of infection. Storms and irrigation flow are the media for the disease. The bacteria invade through the stomata, water holes, and wounds, and the seed bacteria can directly infect the cotyledons. Soil moisture, stems often contact with water, the field of high relative humidity, are likely to cause disease. Melons are heavily planted, densely planted, with excessive nitrogen fertilizer application, poor ventilation in the field, or insufficient fertilizer, and declining growth will aggravate the occurrence of diseases. Prevention of cucumber blight is best not to melons continuous cropping, select well-drained deep-drying land, full of organic fertilizer, rational close planting. Seeds were disinfected before sowing, and 0.3% of Bolin was used for seed dressing. Immediately after the onset of the disease, the following agents should be sprayed to prevent and cure: 1, 600-800 times of behenyl or chlorothalonil (40% suspension). 2. Baoning (60% Duofu WP) 800-1000 times. 3, thiophanate-methyl (70% wettable powder) 800-1200 times. All fields need to be sprayed and sprayed once every 4-5 days for 2-3 consecutive times. In addition, the lesions on the cucumber stems can also be coated 50 to 100 times as much as the above-mentioned medicaments, and the effects are also excellent.
