Anilofos 40% EC Herbicide | Selective Pre- & Early Post-Emergent Weed Control

Anilofos 40% EC (Emulsifiable Concentrate) is a selective organophosphate herbicide designed for pre-emergent and early post-emergent control of annual grasses and sedges in rice, cotton, and vegetables. As an acetyl-CoA carboxylase (ACCase) inhibitor, it disrupts lipid biosynthesis in target plants, providing residual soil activity and foliar uptake for broad-spectrum weed management. The EC formulation ensures rapid emulsification in water, delivering uniform coverage and systemic action.

Technical Specifications

Parameter	Details
Active Ingredient	Anilofos (CAS No. 64249-01-0)
Chemical Class	Organophosphate
Mode of Action	ACCase inhibitor (HRAC Group 1)
Formulation Type	40% EC (400 g/L active ingredient)
Appearance	Clear to pale yellow liquid
Solubility	0.7 mg/L in water (20°C)
pH Range	5.0–7.0
Density	1.05–1.10 g/cm³

Mode of Action

Dual Uptake:
- Soil absorption by emerging seedlings (pre-emergent)
- Foliar uptake by young weeds (early post-emergent)
Biochemical Inhibition:
- Blocks ACCase enzyme, preventing fatty acid synthesis for cell membrane formation.
Symptom Progression:
- 5–7 days: Stunted growth and chlorosis in meristematic tissues
- 10–14 days: Widespread necrosis and plant death

Application Guide

Crop	Target Weeds	Dosage (L/ha)	Application Timing
Rice	Barnyardgrass, crabgrass, sedges	1.0–1.5	Pre-emergence (0–3 days after sowing)
Cotton	Signalgrass, annual bluegrass	1.2–2.0	Pre-plant incorporated or pre-emergent
Vegetables	Foxtail, goosegrass	0.8–1.2	Pre-emergence or early post-emergence

Application Tips

Water Volume: 300–500 L/ha for uniform soil coverage
Adjuvants: Add non-ionic surfactant (0.2–0.5% v/v) for post-emergent applications
Tank Mixes:
- With pretilachlor for enhanced grass control in rice
- With pendimethalin for broad-spectrum control in cotton
Soil Conditions: Apply to moist soil for optimal activation; avoid dry or compacted soils

Key Advantages

Broad-Spectrum Grass & Sedge Control:
- Effective against 20+ grassy and sedge weeds, including resistant biotypes (e.g., ACCase-resistant barnyardgrass).
Residual Activity:
- Provides 21–30 days of soil residual control, reducing re-application needs.
Crop Safety:
- Formulated for minimal phytotoxicity in rice, cotton, and most vegetables when applied as directed.
Flexible Application:
- Suits both pre-emergent and early post-emergent strategies.
Environmental Profile:
- Low mammalian toxicity (LD₅₀ > 2000 mg/kg)
- Rapid soil degradation (DT₅₀ 10–15 days)

Safety & Environmental Notes

Toxicity:
- Moderate toxicity to fish (LC₅₀ 1–10 mg/L); avoid water bodies.
- Low toxicity to bees (LD₅₀ > 100 μg/bee).
Storage:
- Store in original container at 5–30°C; keep away from heat and open flames.
Handling:
- Wear protective clothing; avoid contact with skin and eyes.

Packaging & Compliance

Standard Packs: 1L, 5L, 20L COEX containers
Custom Solutions:
- Private labeling with multilingual instructions
Shelf Life: 3 years under recommended storage conditions

FAQ

Q1: Can Anilofos 40% EC be used in wheat or barley?
A: No, it is primarily registered for rice, cotton, and vegetables. Use for cereal crops may cause phytotoxicity.

Q2: What is the pre-harvest interval (PHI)?
A: PHI varies by crop:

Rice: 45 days
Cotton: 60 days
Vegetables: 30 days

Q3: How to handle resistance management?
A: Avoid consecutive applications; rotate with Group 2 (ALS inhibitors) or Group 15 (acetochlor) herbicides.

Q4: Can it be mixed with insecticides?
A: Generally compatible with most insecticides. Conduct a jar test before large-scale mixing.

Q5: What is the optimal soil pH for Anilofos efficacy?
A: Best performance in soil pH 5.5–7.5; avoid highly acidic or alkaline conditions.

Field Performance

Rice Trials in India:
1.2 L/ha controlled 92% of barnyardgrass and 85% of sedges at 30 days post-application.
Cotton Trials in China:
1.5 L/ha + pendimethalin reduced grass competition, increasing yields by 10–12%.
