Is it true that 8 to 12 lbs of Devrinol 50-DF Ornamental can effectively control dandelions?

Dandelions are often a significant issue in ornamental and turf settings, and their control requires a thorough understanding of herbicides. Devrinol 50-DF is a pre-emergent herbicide primarily effective against certain weed seeds rather than established weeds like dandelions.

Pre-emergent herbicides function by preventing the germination of seeds. In the case of dandelions, they are perennials that reproduce via seeds and vegetative means, meaning that merely applying a pre-emergent during the recommended rate of 8 to 12 lbs may not effectively control them once they are already established.

For effective dandelion control, post-emergent herbicides designed to eliminate existing plants would be the appropriate choice rather than relying on a pre-emergent application. Thus, the notion that applying Devrinol at the specified rate would effectively control dandelions is indeed false.
