- Pre-emerge Herbicide / Natural Fertilizer

From

0

Developed by researchers at Iowa State University, this remarkable alternative to chemical herbicides offers an all-natural pre-emergent control of crabgrass and other persistent, annual grassy and broadleaf weeds.

Dynaweed technology is also a natural fertilizer at 10% organic nitrogen content.

Dynaweed granules are derived from a byproduct of making corn syrup. The main ingredient in Dynaweed is commonly used as a pet food ingredient. Since the discovery of its herbicidal activity in 1988, it has been thoroughly documented as an effective alternative to chemical weed controls.

Dynaweed stops the root development of germinating weed seeds and without feeder roots to provide nutrition, weeds don’t develop. Dynaweed granules are very high in protein and, as they decompose after application, they reduce the need for nitrogen fertilizers.
