I want to use a mixture Certainty and Dimension 2EW in my zoysia (which is now dormant). I have a lot of poa annua and a few other weeds. The application rates per the labels are different for each so may have to apply separately. Is it ok to spray Dimension 2EW and turn right around and spray Certainty or vice versa?
Dimension 2EW Herbicide can be applied prior to weed germination for listed weeds as directed in spring or fall. If applied per each product label instructions as directed they can be applied to established listed turfgrasses including zoysia. Poa annua germinates in the fall so applying Pendulum 2G or other pre-emergent herbicide labeled for the weed and zoysia can be applied at the appropriate timing in your region. Certainty Herbicide should be applied when weeds are actively growing and temperatures are between 65-85 degrees.
