Foramsulfuron 2.5% SC Herbicide

Foramsulfuron 2.5% SC (Suspension Concentrate) is a premium selective herbicide belonging to the sulfonylurea family (HRAC Group 2), designed for post-emergent control of annual grasses and specific broadleaf weeds. As an acetolactate synthase (ALS) inhibitor, it disrupts amino acid biosynthesis in target plants, leading to stunted growth, chlorosis, and eventual death. The SC formulation ensures uniform suspension and easy mixing, making it ideal for precision application in corn, sugarcane, and turfgrass systems.

Technical Specifications

Parameter	Details
Active Ingredient	Foramsulfuron (CAS No. 173159-57-4)
Chemical Class	Sulfonylurea
Mode of Action	ALS inhibitor (blocks amino acid synthesis)
Formulation Type	2.5% SC (25 g/L active ingredient)
Appearance	Off-white flowable suspension
Solubility	0.12 g/L in water (20°C)
pH Range	5.5–7.5
Density	1.0–1.1 g/cm³

Mode of Action

Systemic Uptake:
- Absorbed by weed leaves and roots, translocated via xylem and phloem to meristematic tissues.
Biochemical Inhibition:
- Blocks ALS enzyme, preventing synthesis of valine, leucine, and isoleucine.
Symptom Progression:
- 3–5 days: Growth cessation and chlorosis in new leaves
- 7–14 days: Widespread necrosis and plant death

Application Guide

Crop/Setting	Target Weeds	Dosage (g ai/ha)	Application Timing
Corn (Maize)	Crabgrass, foxtail, barnyardgrass	150–250	Post-emergent, weeds at 2–6 leaf stage
Sugarcane	Annual grasses, lambsquarters	200–300	Post-emergent, weeds at 4–8 leaf stage
Turfgrass (Spot Treatment)	Crabgrass, annual bluegrass	50–100	Early post-emergent, weeds <5 cm tall

Application Best Practices

Water Volume: 200–400 L/ha for corn/sugarcane; 100–200 L/ha for turf spot treatment.
Adjuvants: Add non-ionic surfactant (0.2% v/v) to enhance leaf penetration.
Tank Mixes:
- With atrazine for broad-spectrum control in corn
- With glyphosate for non-selective applications in fallow fields
Weather Conditions: Apply in cool mornings (15–25°C); avoid spraying during rain or high winds.

Key Advantages

Selective Weed Control:
- Targets 20+ annual grassy and broadleaf weeds while sparing crops like corn and sugarcane.
Systemic Efficacy:
- Controls weeds from germination to 6-leaf stage with the ability to translocate to growing points.
Crop Safety:
- Rapid metabolic detoxification in crops reduces phytotoxicity risks when applied as directed.
Residue Management:
- Short soil half-life (10–15 days) allows flexible crop rotation.
Resistance Management:
- Ideal for rotation with Group 15 (acetochlor) or Group 14 (fomesafen) herbicides.

Safety & Environmental Notes

Toxicity:
- Low mammalian toxicity (LD₅₀ > 2000 mg/kg); moderate toxicity to fish (LC₅₀ 1–10 mg/L).
- Avoid application near water bodies; maintain 50 m buffer zone.
Environmental Fate:
- Degrades via microbial action and photolysis (soil DT₅₀ 10–15 days).
- Low volatility; minimal risk of vapor drift.
Storage: Store at 5–30°C, protected from sunlight and freezing.

Packaging & Compliance

Standard Packs: 1L, 5L, 20L COEX containers
Custom Solutions:
- Private labeling with multilingual instructions
- Regulatory support for global markets (EPA, EU, APAC)
Shelf Life: 2 years under recommended storage conditions

FAQ

Can Foramsulfuron 2.5% SC control broadleaf weeds?
Yes, but primarily targets grasses. It controls lambsquarters, pigweed, and other small broadleaf weeds when applied at higher rates.
What is the pre-harvest interval (PHI)?
- Corn: 60 days
- Sugarcane: 90 days
- Turf: No PHI (non-food crop)
Is it compatible with liquid fertilizers?
Yes, but conduct a jar test first. Avoid mixing with high-N solutions (>2% N).
How to manage resistance in target weeds?
- Rotate with herbicides from Groups 1, 15, or 14.
- Avoid consecutive annual applications.
Can it be used in genetically modified (GM) corn?
Yes, safe for use in Roundup Ready® and Liberty Link® corn when applied as directed.

Field Performance

Corn Trials in the US Midwest:
200 g ai/ha controlled 95% of crabgrass and foxtail at 14 days post-application, increasing corn yield by 12%.
Sugarcane Trials in Brazil:
250 g ai/ha + atrazine reduced weed competition, improving cane biomass by 15%.
