PRECISIONPAC® PF-100-0050 Herbicide / WEST / PRE-SEED

Give your wheat crop the clean start it deserves. PrecisionPac® PF-100-0050 herbicide is a flexible pre-emergent Group 2 & 15 herbicide for your spring and winter wheat. PrecisionPac® PF-100-0050 herbicide has burnoff activity as well as extended control on a wide range of grassy and broadleaf weeds. 

The active ingredient, tribenuron-methyl, in PrecisionPac® PF-100-0050 herbicide rapidly stops growth of susceptible weeds. However, typical symptoms (discoloration) of dying weeds may not be noticeable for 1 to 3 weeks after application, depending on growing conditions and weed susceptibility. 

The active ingredient, pyroxasulfone, in PrecisionPac® PF-100-0050 herbicide provides pre-emergent (extended) control of certain weed species. Moisture is necessary to activate PrecisionPac® PF-100-0050 herbicide in soil for pre-emergent weed control. Dry weather following applications of PrecisionPac® PF-100-0050 herbicide may reduce effectiveness. However, when adequate moisture is received after dry conditions, PrecisionPac® PF-100-0050 herbicide will control susceptible germinating weeds. The pyroxasulfone in PrecisionPac® PF-100-0050 herbicide may not provide extended control on weeds that germinate after application but prior to an activating rainfall/irrigation or weeds that germinate through cracks resulting from dry soil.
