I have been unable to get control of the POA in my lawn. I need to overseed every fall, as the POA Annua dies in the summer and leaves many bare spots in my lawn where my fescue has not been able to thrive. Most treatment plans for POA annua require that you do not over seed. What is the best way for me to use this product?
Blindside Herbicide WDG is only labeled for suppression of poa annua (annual bluegrass) however it will not fully control it. For tall fescue, apply at the rate of 0.075 - 0.15 oz per 1000 sq ft. A non ionic surfactant would be recommended to use in the tank mix for best results. Since poa annua and cool season grasses are so closely related, there are few products that will kill the poa annua without also harming the lawn. The only one we are currently aware of is called Prograss which can kill & prevent poa and can be applied at seeding, however it can only be applied to residential lawns by licensed applicators. You may want to see if a service local to you can provide this chemical treatment to your lawn. Your only other option would be to spot-treat with a Roundup-type product and then reseed with the desirable grass type in those areas. Pre emergent applications in late fall and early spring can help prevent poa annua from germinating but if overseeding, you would need to wait until after the 2nd mowing of the newly established turf to apply a pre emergent. Dimension 2EW or Pendulum 2G applications will help prevent weeds from germinating and typically a split treatment in the fall will yield to longer and better prevention of the weeds. Please view our Poa Annua Treatment Guide for more information.
