Timing of Pesticide Applications - Can be improved by making applications when the
pest is susceptible to an application based on its biology, exposure, or climatic
conditions

actively growing.
When to control annual weeds? - Easiest to control in the early spring while they are
still small.
When to control biennial weeds? - Should be treated in the fall or early spring when in
the rosette stage.
When to control Perennial weeds? (Dandelion, white clover) - Can be controlled with a
herbicide application made in the early bloom stage or in the fall.
pesticide resistance - The ability of a pest species that was once effectively controlled
by pesticide is now no longer effective.
