Repeat applications for up to five years. However,the waxy leaf surface and the <br /> dense growth of this weed can make it difficult to obtain adequate coverage with the herbicide,so Aakw <br /> apply the chemical carefully and thoroughly for effective control. • <br /> Top photo,©Kelly Uhing,Colorado Department of Agriculture.Calophasia lunula larva <br /> photo©Bob Richard,USDA APHIS,Invasive.org.
