Empirical Formula

Toxicology

• Acute Toxicity (Rat):

  • Oral LD₅₀: > 5,000 mg/kg (Practically non-toxic)

  • Dermal LD₅₀: > 2,000 mg/kg (Low toxicity)

  • Inhalation LC₅₀: > 5.3 mg/L (Low toxicity)

• Ecotoxicity:

  • Fish LC₅₀ (96h, Rainbow trout): > 100 mg/L (Low toxicity)

  • Honeybee LD₅₀ (Contact): > 25 μg/bee (Low risk)

• Irritation: Non-irritating to skin and eyes (EPA classification).

• Environmental Fate: Soil half-life ~20-60 days; stable to hydrolysis and photolysis.

Applications

• Primary Use: Sulfonylurea herbicide for controlling broadleaf weeds and some grasses (e.g., velvetleaf, crabgrass) in cotton and sugarcane fields.

• Target Crops: Cotton, sugarcane (post-emergence directed spraying).

• Mode of Action: Inhibits acetolactate synthase (ALS), blocking branched-chain amino acid synthesis.

• Application Rate:

  • Cotton: 15-30 g a.i./ha (i.e., 20-40 g/ha of 75% WDG formulation).

  • Sugarcane: 20-45 g a.i./ha (i.e., 27-60 g/ha of 75% WDG formulation).

• Precautions:

  • Avoid spray drift to sensitive crops (e.g., soybeans, vegetables).

  • Soil pH > 7.5 may increase residual phytotoxicity risk.
