I applied an application of prodiamine in early march (NC) on my zoysia. I had some poa come through in some spots and would like to kill it and further prevent anything else coming up. If they can be tank mixed, how long should i wait to water in the prodiamine?
While Certainty and Prodiamine can be mixed together with no issue, Prodiamin is only going to prevent spring germinating weeds from coming up and only if you are getting it down prior to soil temperatures reaching 50-55 degrees as that is when seeds germinate. Also, poa annua is a fall germinating weed so a spring application will not prevent anymore of it coming up. You would need to use something like the Prodiamine in the fall around Sept-Oct 15th to effectively prevent it the next year.
