Detailed Pictures

A. Long-Lasting Residual Control: Provides weeks of effective weed control through soil residual activity, reducing the need for multiple herbicide applications and saving labor costs.

B. Dual Action Flexibility: Effective as both pre-emergence (applied before weed germination) and early post-emergence (applied to young weeds) herbicide, offering application flexibility.

C. Crop Safety in Established Plantings: When applied as directed, it is highly selective for established deep-rooted crops like sugarcane, citrus, and grapes, providing season-long weed suppression without crop injury.

D. Superior Formulation Safety: The low-dust WDG formulation significantly reduces operator exposure during handling. It is solvent-free, non-flammable, and generates minimal odor, enhancing workplace safety.

Mixing, Dosage & Critical Usage Instructions

Dosage Rate: Typical range: 1.0 - 3.0 kg/ha. Rate depends on soil type (use higher rates on heavy soils, lower on sandy soils), target crop, and weed pressure. Always follow locally registered label rates.

Critical Application Timing:

Pre-emergence: Apply to clean, prepared soil immediately after planting/sowing but before weed seeds germinate. Light irrigation or rainfall (5-10 mm) within 7 days is essential to activate the herbicide.
Early Post-emergence: Apply to young, actively growing weeds (1-3 leaf stage) in tolerant crops.

DUAL-ACTION WEED SPECTRUM 
 
Effectively targets both annual grasses and broadleaf weeds, delivering comprehensive weed management in a single product.

FAQ

Q1: What is the main difference between WDG and WP (Wettable Powder)?
A: WDG is a low-dust, granular formulation that is safer and cleaner to handle, with better flowability and easier measuring. WP is a fine powder that can generate more dust. WDG is the modern, user-friendly evolution of WP.

Q2: Can Diuron be used in newly planted orchards or vineyards?
A: Generally not for very young plants. It is typically recommended for established plantings (e.g., citrus trees older than 2-3 years, established grapevines) where the root system is deep enough to avoid uptake of the herbicide from the treated soil zone. Always check crop-specific guidelines.

Q3: How long does the residual effect last, and does it affect crop rotation?
A: Residual control can last 6 to 12 weeks, depending on soil and rainfall. It can affect rotation to sensitive crops (e.g., vegetables, small grains). Always consult the label for specific crop rotation restrictions (plant-back intervals) for your region.

Q4: Is this product suitable for use in aquatic environments or ditch banks?
A: No. Diuron is toxic to aquatic organisms. It is not labeled for use in or near water, including ditches, canals, or ponds. It is intended for terrestrial agricultural and industrial use only.

Q5: What is the MOQ, packaging, and lead time?
A: Standard MOQ is one 20ft container (approx. 18-20 MT). We offer 1kg and 25kg bags. Lead time is 25-35 days after deposit to major ports. Contact us for a precise CIF/FOB quote.
