CYMBUSH^® is ICI America's new broad-spectrum pyrethroid insecticide. During the past five years in ICI's Research and Development and Technical Service programs, CYMBUSH has demonstrated a high degree of activity on many cotton insect pests. When compared to commercially available pyrethroids, CYMBUSH generally gives a more rapid knockdown of insect pests and a broader spectrum of control. There are two commercially available formulations of CYMBUSH, a 3.0 lbs per gallon emulsifiable concentrate (E.C.) to be used with water, and CYMBUSH OL, a 3.0 lbs per gallon oil liquid formulation designed specifically for use in oil-based sprays.
