A comprehensive pre-emergence herbicide solution for effective weed control in rice and corn fields, available through factory direct wholesale and OEM services.
Product Overview
Product Name
Acetochlor + Pretilachlor EC
Active Ingredients
Acetochlor + Pretilachlor, 500g/L total content
Formulation Type
EC (Emulsifiable Concentrate)
Chemical Class
Chloroacetamide (α-chloroacetamide) herbicides
HRAC Mode of Action Group
Group 15 (VLCFA – Very Long Chain Fatty Acid inhibitors)
Applicable Crops
Rice (direct-seeded and transplanted paddies), Corn
Target Weeds
Barnyard grass, crabgrass, Asian sprangletop, and other annual grasses; select sedges and broadleaf weeds
Acetochlor functions as a VLCFA synthesis inhibitor, disrupting cell membrane formation in germinating weeds by inhibiting very long-chain fatty acid synthesis. This prevents root and shoot development in emerging seedlings while remaining selective for tolerant crops like corn.
Pretilachlor operates through a similar mechanism but is specifically optimized for rice paddies. It inhibits protein and lipid biosynthesis necessary for cell division, targeting actively growing parts of weeds. Most commercial formulations include safeners like fenclorim to enhance rice crop safety.
Combination Benefits
The combination of acetochlor and pretilachlor provides comprehensive field coverage across different agricultural conditions:
Acetochlor: Optimized for dryland/upland conditions in corn fields
Pretilachlor: Specifically designed for flooded paddy conditions in rice cultivation
Broadens effective weed control spectrum while maintaining consistent mode of action
Simplifies application protocols for growers managing mixed cropping systems
Application Guidance
Timing:
Corn fields: Apply as pre-emergence soil treatment immediately after planting, before weed emergence
Direct-seeded rice: Apply 3-5 days after sowing, before rice seeds sprout or during early germination
Water Management (Critical for Rice): Maintain 2-3 cm water level during application for optimal herbicidal action in rice paddies.
Safety Considerations:
Conduct small-area trials for rice variety sensitivity assessment
Rotate with herbicides of different modes of action to delay resistance development
Always follow product label instructions and local regulatory recommendations
Frequently Asked Questions
Q: Are acetochlor and pretilachlor the same active ingredient? A: No. They share the same chemical class and mode of action but differ in registered crop use – acetochlor for upland crops like corn, pretilachlor for rice paddies.
Q: Is this a pre-emergence or post-emergence herbicide? A: Pre-emergence, soil-residual herbicide. Must be applied before weeds germinate or emerge.
Q: Will pretilachlor injure rice seedlings? A: Under correct application conditions, it is selective and safe for rice. Check for safener content and conduct trials for sensitive varieties.
Q: Is OEM or custom packaging available? A: Yes, we offer OEM processing and custom packaging tailored to export market requirements.
