Lipids are vital to the integrity of cell membranes and to new plant growth.
Broad-leaf plants are tolerant to these herbicide families, but almost all perennial and annual grasses are susceptible. These herbicides are taken up by the foliage and move in the phloem to areas of new growth. Sugarbeet is not injured by cyclohex-anediones even at high rates. Sugarbeet is not injured by aryl-oxyphenoxypropionates used alone but would be injured by mixtures with other herbicides such as in Dakota, Tiller or Cheyenne.
