After applying Poa Constrictor Herbicide we do recommend waiting at least 24 hours before watering or irrigation for best results.
Poa Constrictor Herbicide per product label can be applied at same time as Tall Fescue overseeding.
The Poa Constrictor product label does not state that a surfactant/crop oil/adjuvant is needed so you would not need to add anything.
Poa Constrictor Herbicide does not give a max annual rate on the product label, it only lists that you can apply 2-3 times at 21-28 day intervals. The rate to use is 24-48 oz per acre or ¾ – 1/12 flo oz per 1000 sqft. The specific instructions for Turf Type Tall Fescue are as follows: Make applications in the fall. If overseeding with TTTF, application may be done at the same time as seeding.
Tenacity is only labeled to suppress poa annua when applied as a pre-emergent application. It would not be tank mixed with Poa Constrictor Herbicide as a post emergent application for control of it.
A second application of Poa Constrictor Herbicide can be applied 21-28 days following your initial applications. Results will vary depending on application, temperature, turf stress etc.
How much Poa Constrictor Herbicide is needed depends on the turf type you are applying to. You use any where from 9/16 fl oz to 2 ¼ fl oz per 1000 sqft per the product label.
Floratam is not listed on the Poa Constrictor label as having been tested for tolerance (only Raleigh St. Augustine is specified). Since Floratam is notoriously sensitive, and the product label does specify that the herbicide may cause discoloration on St. Augustine turfgrass, we recommend testing an inconspicuous area for tolerance before treating the entire lawn.
Yes, Poa Constrictor Herbicide is labeled for tall fescue when used as directed on the label.
No, Poa Constrictor Herbicide is only labeled to be applied on your lawn.
Poa annua germinates primarily in the fall, and turf type Tall Fescue is also typically overseeded in the fall rather than spring, because this is when the seed takes best in the year. That is likely why the Poa Constrictor label states only fall instructions in the seeding and timing rate table on the Product Label. In general, if its safe to be used in the fall, you should be able to do the same in the spring, its just not the normal season, and you would only get spotty poa annua prevention since the majority of the cycle occurred this past fall/winter.
Per the product label for Poa Constrictor Herbicide: Make applications to TTTF in the fall and if overseeding you may apply at the same time as seeding.
There is no wait time to apply Poa Constrictor Herbicide after aerating and fertiizing.
How much Poa Constrictor Herbicide is needed depends on the turf type you are applying to. You use any where from 9/16 fl oz to 2 ¼ fl oz. Please refer to the product label for complete instructions.
