Will Atrazine kill (spurweed (burweed) in my lawn?


Southern Ag Atrazine Weed Killer for St Augustine Grass does list spurweed (burweed) on the label if used as directed.  Spurweed (burweed) is best controlled with a pre-emergent before the weed germinates. This winter annual germinates in the fall. A fall pre-emergent and spring pre-emergent are suggested prior to ground temperatures reaching 55 degrees. Pendulum 2G is labelled for both Cool and Warm Season established lawns. Please refer to the product label for your lawn type and application rates.
