I'll be using Prodiamine (half max in Sept, half max in Feb), along with Princep in Oct, Pennant Magnum in early April, and Dimension in June and late July. I'll be using a bit less than the various annual recommended maximums for all of these and wondered if by using so many I will cause turf damage.
The amount per acre per year is for the Prodiamine 65 WDG (Generic Barricade) not the calculation of other pre-emergents used on the turf at other times of the year. If each product is applied at the appropriate times and as directed on the product label for your turf species type, it should not cause injury to the established turf.
