Thunder® kills weeds by root and/or foliage uptake and rapid translocation to the growing points. Adequate soil moisture is important for optimum Thunder™ activity. When adequate soil moisture is present, Thunder™ will provide residual control of susceptible germinating weeds; activity on established weeds will depend on the weed species and the location of its root system in the soil.
