Difenoconazole is a kind of Systemic fungicide with a novel broad-range activity protecting the yield and crop quality by foliar application or seed treatment.
1. Suitable for crops and safety.
Tomatoes, beets, bananas, cereal crops, rice, soybeans, horticultural crops, and various vegetables. When wheat and barley are treated with stems and leaves (wheat plant height of 24 to 42 cm), the leaves sometimes show discoloration, but they do not affect the yield.
2. Control object.
For the subcapsular subphylum, Basidiomycotina and including Alternaria, Diptera, Cercospora, S. genus, Coccidia, Pleurotus, Cylindrosporium, Cercospora Semi-known bacteria, such as the genus of the genus, the genus of the genus Phytophthora, the rust fungus and certain species of pathogens have long-lasting protection and therapeutic activity. At the same time, beet brown spot, wheat blight, leaf blight, rust and mildew caused by several pathogenic bacteria, apple scab, powdery mildew, grape powdery mildew, potato early blight, peanut leaf spot, Net spot disease has good therapeutic effects.
Mainly used for foliar treatment and seed treatment. Among them, 10% difenoconazole water-dispersible granules are mainly used for stem and leaf treatment, and the dosage is 30-125g(ai)/hm2. The application of 10% difenoconazole water-dispersible granules is mainly used to control pear black. Star disease, apple spotted leaf disease, tomato plague, watermelon blight, pepper anthracnose, strawberry powdery mildew, grape anthracnose, black pox, citrus scab and the like.
★Pear scab. In the early stage of the disease, the granules are dispersed with 10% water, 6000-7000 times, or 14.3-16. 6g per 100 L of water (effective concentration 14, 3-16, 6 mg/L). When the incidence is serious, the concentration can be increased. It is recommended to use 3000~5000 times liquid or 20~33g of water preparation per l00L (effectiveness 20~33mg/L), and spray 2~3 times continuously at intervals of 7~14d.
★Apple spotted leaf disease. In the initial stage of the disease, use 2500 ~ 3000 times liquid or 33 ~ 40g per 100L water (effective concentration 33 ~ 40mg / L), 1500 ~ 2000 times liquid or 50 ~ 66.7g per 100L water addition when the disease is serious (effective concentration 50 ~66.7mg / L), interval 7 ~ 14d, continuous spraying 2 to 3 times.
★Grape anthracnose, black pox disease. Use 1500 ~ 2000 times liquid or every 100L, water plus preparation 50 ~ 66.7g (effective concentration 50 ~ 66.7mg / L)
★Citrus scab. Spray with 40 to 50 g (effective concentration 40 to 50 mg/L) of 2000 to 2500 times or every 100 L of water.
★Watermelon vine wilt disease. The preparation per acre is 50-80 g (active ingredient 5-8 g).
★Strawberry powdery mildew disease. The preparation per acre is 20-40g (active ingredient 2~4g).
★Difenoconazole should not be mixed with copper preparations. Because the copper preparation can reduce its bactericidal ability, if it is really necessary to mix with the copper preparation, it is necessary to increase the dosage of difenoconazole by more than 10%. Although difenoconazole is systemic, it can be transported to the whole body of the plant through the transporting tissue. However, in order to ensure the control effect, the water consumption must be sufficient when spraying, and the whole plant should be sprayed evenly.
★The spray volume of watermelon, strawberry and pepper is 50L per acre. The fruit tree can determine the amount of liquid spray according to the size of the fruit tree, the spray volume of the large fruit tree is high, and the spray volume of the small fruit tree is the lowest. The application should be carried out in the morning and evening when the temperature is low and there is no wind. If the relative humidity of the air is lower than 65%, the temperature is higher than 28 °C, and the wind speed is greater than 5m per second, the application should be stopped.
★Although difenoconazole has the dual effects of protection and treatment, in order to minimize the damage caused by the disease, the protective effect should be fully exerted. Therefore, the application time should be sooner rather than later, and the spraying effect should be best in the early stage of the disease.
