3. Uses & Target Spectrum
Primary Crops: Soybean (main), groundnut (peanut), pulses/legumes, alfalfa (newly seeded), and direct-seeded/transplanted rice.
Application Timing: Pre-emergence and early post-emergence (when weeds are at the 2–3 leaf stage).
Target Weeds (Examples): Cyperus rotundus (Purple nutsedge), Echinochloa spp. (Barnyard grass), Dinebra arabica, Digitaria sp. (Crabgrass),                                                  Brachiaria mutica, Commelina spp., Euphorbia geniculata, and Cyanotis axillaris.
Mode of Action: Systemic herbicide with both foliar contact and soil residual activity. It inhibits acetohydroxyacid synthase (AHAS), blocking the                                   biosynthesis of branched-chain amino acids (isoleucine, leucine, and valine), resulting in rapid weed growth arrest and plant death.

4. Dosage Reference
Soybean (General Reference): 100 g/ha formulation (70 g a.i./ha) diluted in 500 L/ha of water.
Alfalfa (Newly Seeded): 140 g/ha + non-ionic surfactant at 200 ml/100 L water (0.2% v/v); effective against broad-leaved weeds with high crop     

                                    safety up to 160 g/ha.
Application Note: Always calibrate dosage according to local registration guidelines, weed spectrum, and crop growth stage. Adding an adjuvant                          (surfactant or ammonium sulfate / AMS) is recommended for optimal post-emergence efficacy.
