10% Oxazolidine Water Dispersible Granule is a newly developed broad-spectrum, high-efficiency, systemic triazole fungicide by Shandong Dongtai Agrochemical Co., Ltd. This product effectively inhibits the growth of pathogenic bacteria by blocking the biosynthesis of ergosterol, a vital component of fungal cell membranes. It also strongly suppresses spore formation, making it highly effective in disease prevention and control. The fungicide offers three key functions: prevention, treatment, and eradication. It is rain-resistant, long-lasting, and suitable for various crops. It can protect against black spot disease, powdery mildew, leaf spot, rust, and anthracnose caused by ascomycetes, basidiomycetes, and deuteromycetes. A single application can manage multiple diseases, making it a versatile choice for farmers.
For apple spotted leaf disease, apply 2500–3000 times dilution (33–40 g per 100 liters of water) during early stages, or 1500–2000 times dilution (50–66.7 g per 100 liters) if the infection is severe. Spray every 7–14 days for 2–3 applications. It also helps control brown spot, mildew, and leaf spot on apples.
For pear black spot disease, use 6000–7000 times dilution (14.3–16.6 g per 100 liters) at the early stage, or 3000–5000 times (20–33 g per 100 liters) for more severe cases. Apply every 7–14 days for 2–3 times. It is effective against brown spot, powdery mildew, and leaf spot on pears.
In Chinese cabbage, apply 35–50 g per acre (3.5–5.0 g active ingredient) with water. Spray once every 14 days to manage black spot disease.
For tomato early blight, use 800–1200 times dilution (125 g per 100 liters) or 40–60 g per mu (4–6 g active ingredient). Spray every 7–10 days for two applications to treat both gray mold and leaf mold.
For watermelon anthracnose, apply 50–75 g per 100 liters (5–7.5 g active ingredient) every 14 days. It helps prevent watermelon blight.
For melon powdery mildew, use 2000–3000 times dilution and spray 2–3 times every 7–10 days.
For cucumber scab, apply 2000–5000 times dilution and spray every 7–14 days for 2–3 times.
For strawberry powdery mildew, use 1500–2000 times dilution and spray 2–3 times every 7–10 days.
For grape anthracnose and citrus scab, apply 2000–3000 times dilution and repeat every 7–14 days for 2–3 sprays.
For garlic leaf blight, use 1500 times dilution and spray 3–4 times every 7–10 days.
For celery spot blight, apply 1500 times dilution and spray 2–3 times every 7–10 days.
Oxazolidine is highly systemic and can be transported throughout the plant via vascular tissues. For optimal effectiveness, ensure sufficient water volume and even coverage. It provides both protective and curative effects, so early application is recommended to minimize damage. The best results are achieved when applied at the initial stages of infection.
Watermelon, strawberry, grape, cucumber, and tomato crops require about 50 liters of solution per mu. Fruit trees should be sprayed according to their size—larger trees need more water, while smaller ones require less. Applications should be made during cool, low-wind periods, preferably in the morning or evening. Avoid applying when humidity is below 65%, temperature exceeds 28°C, or wind speed is over 5 m/s.
The China Pesticide Network reminds users to follow these precautions:
1. Do not mix oxazolidine with copper-based products, as this may reduce its efficacy. If mixing is necessary, increase the oxazolidine dosage by over 10%.
2. No specific antiviral agent is available. If the product gets into eyes or skin, rinse thoroughly with water.
3. Do not dispose of leftover solution in fish ponds or rivers.
4. Store the product in a cool, dry, well-ventilated area, and keep it in the original packaging.
By following these guidelines, you can maximize the benefits of 10% Oxazolidine Water Dispersible Granule while ensuring safe and effective use.
Gate valve is a relatively common general-purpose valve, the use of a wide range of applications, mainly in water conservancy, metallurgy and other industries, its extensive use of performance has been recognized by the market.
Gate valve structure: gate valve is the use of the gate and seat to control the opening and closing of the valve. Gate valve mainly has a valve body, valve seat, gate, valve stem, valve cover, stuffing box, packing gland, stem nut, hand wheel and other components. Depending on the change of the relative position between the gate and the valve seat, the channel size can be changed and the channel can be cut off. In order to make the gate valve close tightly, the mating surface of the gate plate and the valve seat are ground.
