Frontier Optima

Frontier Optima is a selective pre-emergence herbicide formulated as an emulsifiable concentrate containing 720 g/L dimethenamid-P. Absorbed through the roots of germinating weeds, it controls annual grasses and several broadleaf weeds in corn, soybean, pea, sugar beet, sunflower and potato. It is applied by spraying before or after sowing but ahead of crop emergence, or on corn up to the six-leaf stage, at 0.8 to 1.2 litres per hectare. Its high water solubility keeps performance stable even in dry soils.
