Application Scenarios

FAQ

Q1: What is Diuron 63% SC and how does it work?
A: Diuron 63% SC is a selective, root-absorbed herbicide in a Suspension Concentrate formulation. It works by inhibiting photosynthesis (Photosystem II) in weeds. Applied to the soil, it is taken up by emerging weed roots and seedlings, stopping their growth.

Q2: What is it mainly used for, and which weeds does it control?
A: It is primarily used for residual, pre-emergence control of annual grasses and broadleaf weeds. It effectively controls problem weeds like barnyardgrass, crabgrass, chickweed, and pigweed. It is a key herbicide in asparagus, citrus, sugarcane, cotton, and non-crop areas like industrial sites and railroad tracks.

Q3: What is the key advantage of the SC formulation?
A: The Suspension Concentrate (SC) formulation offers excellent suspension in the spray tank, is easy to mix and handle, provides consistent coverage on the soil surface, and has low risk of clogging nozzles.

Q4: What are the most important factors for successful application?
A: Success depends on three factors:

Timing: Apply pre-emergence to weeds, typically before or immediately after crop planting/emergence.
Soil Activation: Requires light rainfall or irrigation (about 12mm) after application to move the herbicide into the weed germination zone.
Soil Type: Efficacy and safety are highly dependent on soil texture and organic matter. Follow label rates carefully based on your specific soil type to avoid crop injury or poor control.

Q5: Are there any important precautions regarding its use?
A: Yes, please note:

Crop Safety: Some crops are sensitive. Ensure it is registered for your specific crop and variety, and avoid root contact with established crops.
Rotation: Due to its soil persistence, observe label instructions for planting sensitive rotational crops (like small grains or vegetables) after use.
Environment: It can be toxic to aquatic organisms. Avoid application near water bodies or areas where runoff may occur.

Q6: Why should I choose this product for my weed management program?
A: Diuron 63% SC provides long-lasting residual weed control, reducing the need for multiple applications. It is a proven, cost-effective foundation for managing a broad spectrum of weeds in tolerant crops and non-crop areas under proper soil and management conditions.
