Subject: Preemergence Crabgrass Control

Forsythia has started to bloom in some parts of the state. Preemergence crabgrass and annual weed control products for turf should be applied before forsythia flowers drop. Products should be watered in. Apply products before a light to moderate rainfall is expected. If rainfall does not occur within a few days, use an irrigation event of at least 1/4 inch to water in product. Preemergence products that do not receive rainfall or irrigation may not work effectively, this was a problem during the 2001 growing season. Remove winter debris from turf to insure application uniformity. Siduron should be used if a spring renovation or overseeding is being done.
