Techniques for the use of 10% oxazolidine water-dispersible granules on plants

10% oxazolidine water dispersible granule is a broad-spectrum, high-efficiency, systemic triazole fungicide newly developed by Shandong Dongtai Agrochemical Co., Ltd. It inhibits the normal growth of pathogenic bacteria by inhibiting the biosynthesis of ergosterol, and strongly inhibits the sporulation of plant pathogenic bacteria. In the process of controlling diseases, it shows three major functions of prevention, treatment and eradication. It is resistant to rain and has long-lasting effects. It can effectively prevent black spot disease and powdery mildew caused by pathogens such as ascomycetes, basidiomycetes and deuteroms. Leaf spot, rust, anthracnose, etc., can prevent a variety of diseases in one dose. Oxepazole is safe for crops and can be applied to a variety of crops.
1. Pear black spot disease In the early stage of the disease, 10% oxazolidine water dispersing granules 6000-7000 times solution or 16.3~16.6 grams per 100 liters of water (effective ingredient 14.3~16.6 mg/liter). When the incidence is serious, the concentration can be increased. It is recommended to use 3000~5000 times liquid or 20~33 grams per 100 liters of water (effective concentration 20~33 mg/l), interval 7~14 days, continuous spraying 2~3 times. It can treat pear brown spot disease, powdery mildew and leaf spot disease.

2. In the early stage of apple spotted leaf disease, use 10% oxazolidine water to disperse granules 2500~3000 times liquid or 33~40 grams per 100 liters of water (effective concentration 33~40 mg/L). When the incidence is serious, use 1500~2000 Add liquid 50~66.7g (active ingredient 50~66.7mg/L) per 100L of water, interval 7~14 days, spray 2~3 times continuously. At the same time, it also treats apple brown spot disease, mildew disease, powdery mildew and leaf spot disease.
3. In the early stage of tomato early blight, use 10% oxazolidine water to disperse granules 800~1200 times liquid or add 83~125g per 100 liters of water (effective concentration 83~125mg/L) or 40~60g per acre ( The active ingredient is 4~6g). Between 7 and 10 days, continuous spraying twice, can treat both gray mold and leaf mold.
4. Chinese cabbage black spot disease In the early stage of the disease, 10% oxazolidine water dispersion granules 35 ~ 50 g / acre (active ingredient 3.5 ~ 5.0 grams) spray on the water surface, spray once every 14 days.
5. Watermelon anthracnose Before the onset or initial stage, use 10% oxazolidine water dispersing granules 50~75g (active ingredient 5~7.5g) per acre to spray on water leaf surface, spray once every 14 days. It can treat watermelon blight.
6. Melon powdery mildew In the early stage of the disease, use 10% oxazolidine water dispersing agent 2000~3000 times liquid, spray 2~3 times every 7~10 days.
7. Cucumber Scab Disease In the early stage of the disease, use 10% oxazolidine water to disperse granules 2000~5000 times, every 7~14 days, continuously spray 2~3 times.
8. Strawberry powdery mildew In the early stage of the disease, granules of 1500~2000 times are dispersed with 10% oxazolidine water, and sprayed continuously for 2~3 times every 7~10 days.
9. Grape anthracnose, citrus scab disease In the early stage of the disease, use 10% oxazolidine water to disperse granules 2000~3000 times, every 7~14 days, continuously spray 2~3 times.
10. Garlic leaf blight In the early stage of the disease, 1500 times solution of granules is dispersed with 10% oxazolidine water, and sprayed continuously for 3~4 times every 7 to 10 days.
11. Celery spot blight In the early stage of the disease, 10% oxazolidine water is used to disperse the granules 1500 times, 7 to 10 days apart, for 2 to 3 times.
Oxepazole is highly systemic and 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. Oxepazole has the dual effects of protection and treatment, and should fully exert its protective effect in order to minimize the damage caused by the disease. Therefore, the application time should be sooner rather than later, and the spraying effect should be best in the early stage of the disease.
The spray volume of watermelon, strawberry, grape, cucumber and tomato is 50 liters per mu. 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 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 the wind is low. On sunny days, the relative humidity of the air is lower than 65%, the temperature is higher than 28 °C, and the application should be prohibited when the wind speed is greater than 5 meters per second.
Note: 1. Oxepazole should not be mixed with copper preparations. Because the copper preparation can reduce the bactericidal ability of the oxadiazole, if it is really necessary to mix with the copper preparation, it is necessary to increase the amount of the oxazole more than 10%. 2. No special anti-virus agent, symptomatic treatment. If you accidentally splash into your eyes and skin, rinse with plenty of water. 3. Do not pour the remaining liquid into fish ponds or rivers. 4. In a cool, dry, ventilated place, the drug must be stored in its original packaging.
