Princep Liquid is manufactured by Syngenta and was formerly known as Simazine 4L. It’s a preemergent herbicide which controls a wide range of weeds, including Poa annua (ragweed), Crabgrass and more than 40 other annual and broadleaf weeds.

Princep Liquid Herbicide is a pre-emergent weed killer that prevents a wide range of broadleaf and grass weeds, including crabgrass, goosegrass and groundsel (see the label for more information).

Princep will kill any weeds already present, but not those that are yet to emerge. Princep is also effective in protecting crops from weeds.

Princep Liquid Herbicide can be used before or after weeds are visible.
