Q

What chemical can be used to selectively eradicate poa annua from my fescue lawn?

A

Because poa annua and and fescue are so closely related, there are few products that will kill the poa annua without also harming the fescue. The only one we are currently aware of is called Prograss. Your other options would be to either spot-treat with a Roundup-type product and then reseed with…

Because poa annua and and fescue are so closely related, there are few products that will kill the poa annua without also harming the fescue. The only one we are currently aware of is called Prograss. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the fescue in those areas, or you can use a preemergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.

For post-emergent control of Poa Annua in cool season grass there's only one that is labeled for it and it's Prograss. You can hit it with a high nitrogen fertilizer to burn it out or wait until temperatures hit 85 degrees and up for it to die out. The best time to treat is in the fall with a pre-emergent, one of the best ones for this is Pendulum or Dimension. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the cool season grass you have in those areas.

Q

Overseeding Safety Interval for Fine Fescue and Colonial Bentgrass?
What is the Overseeding Safety Interval (Weeks After Treatment) for Fine Fescue and Colonial Bentgrass? I have applied the second treatment on what is likely now a mostly perennial ryegrass lawn and would like to overseed with a fine fescue/colonial bentgrass mix. (10 % SR 7150 Colonial Bentgrass, 40 % SR 5210 Strong Creeping Red Fescue, 50 % SR 5100 or SR 5130 Chewings).

For specific recommendations on overseeding your yard, we recommend contacting your local Master Gardner. They are experts in your county that are familiar with the weather, soil and turf conditions and can best advise on a schedule that will best meet your needs.

Q

Is it too late for an early spring application of Prograss EC Herbicide on non-dormant bermudagrass?
I have a hybrid bermudagrass lawn that is NOT overseeded with rye. The lawn has been practically overtaken by poa annua, but the bermudagrass is now starting to emerge from dormancy. Is it too late for an early spring application, and will an application harm the bermudagrass? Do I need to wait until late fall/early winter to attempt to control the annual bluegrass?

A

You should not apply Prograss EC Herbicide to Bermudagrass during Spring transition. Per the product label: "The final PROGRASS Herbicide application should be made to Bermudagrass no later than February 1st or 4 weeks prior to breaking of winter dormancy.

You should not apply Prograss EC Herbicide to Bermudagrass during Spring transition. Per the product label: "The final PROGRASS Herbicide application should be made to Bermudagrass no later than February 1st or 4 weeks prior to breaking of winter dormancy. Late applications (within 4 weeks of breaking dormancy) to turf that will be breaking dormancy may temporarily delay resumption of active growth (spring green-up) of Bermudagrass in the spring." Another popular product for controlling poa annua in Bermudagrass is Certainty Herbicide. Certainty will also work best when the poa is young (before tillering). We do not recommend applying post-emergent herbicides to Bermudagrass during Spring green up. In warm areas, the poa will die out on its own in the summer, and then we would recommend using a pre-emergent herbicide such as Prodiamine 65 WDG in late summer and fall to prevent the poa annua going forward.
