What is Prodiamine?

Prodiamine is the active ingredient found in the popular herbicide Barricade and other lawn and garden products, such as Prodiamine 65 WDG (Generic Barricade).  It is labeled as a pre-emergent herbicide to control crabgrass, broadleaf weeds and a number of undesirable grasses including spurge, bluegrass and witchgrass.

More about pre-emergent herbicides:

It is important to make the distinction that pre-emergent herbicides, like prodiamine, do not destroy weeds entirely but rather prevent growth. That is why you must apply pre-emergent herbicides annually to retain desired results.

Prodiamine inhibits plant cell growth so that weeds are unable to grow.
