According to the Hi-Yield Crabgrass Weed Control product label you should wait at least 8 weeks after a single application if you used the 1/2-2 lbs pounds of active ingredient per acre rate or 12-16 weeks if you used the higher application rate of 2-3 lbs of active ingredient per acre. The product label also recommends that you increase the amount of seed used and use equipment designed to put the seed in contact with the soil.
