Agricultural sulfur powder (Q/WXB02-2017)
I. Basic Information
1. Core ingredient: Sulfur (S), with a purity of 99.9%, meeting relevant agricultural standards.
2. Appearance: Pale yellow powder with a fineness of 200–400 mesh (facilitating dispersion).
3. Key characteristics: Stable at room temperature, insoluble in water; melts around 115℃ and releases sulfur dioxide upon combustion; low to slightly toxic, safe for natural enemies, and difficult for pathogenic bacteria to develop resistance against.
4. Mechanism of action: Disrupts the cell membranes and enzyme systems of pathogenic bacteria; converts into sulfate to replenish sulfur and regulate soil pH.
II. Core Features
1. Disease and pest control: Prevent fungal diseases (such as rust and powdery mildew), and provide supportive treatment for spider mites.
2. Soil Conditioning: Reduce the alkalinity of the soil to a pH of 6.0–7.0, improve soil structure, and enhance the availability of trace elements.
3. Nutritional supplementation: Use as a sulfur fertilizer to prevent growth problems caused by sulfur deficiency in sulfur-demanding crops such as rapeseed.
III. Usage Restrictions
1. Crop and Timing Restrictions: Prohibited or used with caution for cucurbits and stone fruits; prohibited under high temperatures (>30℃). Best applied at the early stage of disease onset or during spring and autumn for disease management.
2. Application method and dosage restrictions: Use at the recommended rate; do not mix with alkaline fertilizers or pesticides. Before mixing, conduct a compatibility test first.
3. Safety and Environmental Restrictions: Wear protective gear during operation; keep away from sources of ignition. Avoid contact with water, and dispose of leftover chemicals and packaging according to regulations.
IV. Scope of Application
Suitable for regulating soil nitrification and pH in agriculture, as well as for insecticidal and fungicidal purposes and for controlling powdery mildew.
