Prevention and treatment of cut rose powdery mildew

Powdery mildew is the most common disease in the rose leaf. It should be prevention-based and combined with prevention and treatment to achieve substantial results.
Prevention methods include: 1. Before germination in early spring, spray a carbendazim WP 600 times to kill overwintering germs. After the Chinese rose plant leaves are planted in the Chinese Spring, the carbendazim wettable powder 1000 times solution is sprayed every half month for 3 to 4 consecutive times to consolidate the preventive effect; or every other half of the same amount of Bordeaux mixture is used after the leaf is spread. Spray once, for 3 to 4 times, to form a good protective film on the leaves of the rose to prevent the invasion of pathogenic spores. 3. Use 27% of high-fat film emulsion 50 to 100 grams, add 7 liters of water before onset or during onset, evenly spray on the positive and negative sides of the leaves, spray once every other week, 2 to 3 times in succession, can form a The light-permeable and air-permeable protective film not only prevents the invasion of pathogen spores, but also does not affect the photosynthesis and respiration of the leaves. In addition, greenhouse cultivation cut rose, ventilation should be increased, and give adequate light, increase plant resistance, can significantly reduce the occurrence of powdery mildew; also avoid excessive nitrogen fertilizer, appropriate application of phosphorus and potassium fertilizer, pruning and burning in early spring and sick The foliage is also very important.
Treatment methods: 1. For disease-free period, use 40% polysulfide suspension (a broad spectrum fungicide made from a mixture of carbendazim and sulfur) 15 to 20 grams, add water 7.5 to 10 liters to spray the leaves, every 7 Spraying once every 10 days, 2 to 3 times in a row, the effect is quite good. 2. Control with fluconazole, spraying the first drug at the early stage of the disease, spraying it twice at 10 days intervals, generally using 30% of fluconazole 800 to 1000 times; pay attention to wash hands and feet, etc. immediately after application. Sites, and mouthwash, do not pour the remaining pesticides into paddy fields, rivers or fish ponds to avoid harm to humans and livestock; it is the preferred pesticide for the treatment of powdery mildew. 3. Choose 50% thiophanate-methyl 1500-fold solution, 20% rust-free emulsifiable concentrate 3000 times solution, and 50% benzene-based wettable powder 1000-times solution. Optionally, spray the plant once a week. For 2 to 3 consecutive times, there is also a good control effect.
