Hello again, . I applied pre emergent containing Dithiopyr 3,5,-pyridinedicarbothioic acid,2-difluoromethyl-4-2-methylproply-6-trifluoromethyl-s,s-dimethyi ester. April 3, From your answers, please confirm that I re apply 6 weeks later. Also is it preferable if grass is cut prior to application? I am concerned that the grass may have been a bit tall but I wanted to get it on before the rain. Thanks. P.S. I wrote this in another ask an expert format but I don't know if it was the correct way so writing again.

You can apply 6-8 weeks later. You can cut the grass before application. Follow label directions regarding watering the product in and application.
