The label of Triad Select Herbicide states to apply only to dormant St. Augustine (common, Raleigh, and Seville varieties grown in TX, LA, MS only. Otherwise, this product will injure or kill these types of turfgrass.
The product label for Triad Select Herbicide suggests the use of a non-ionic surfactant, if one is to be added to the spray solution. Since the Monterey Herbicide Helper contains petroleum distillates, we recommend exercising caution if mixing this with a selective herbicide such as the Triad Select. An oil concentrate can increase selectivity on the desirable turfgrass, especially if it is a more sensitive species.
We suggest testing a small area for tolerance before treating a large area with the Monterey Herbicide Helper or using a non ionic surfactant as suggested on the Triad Select product label instead.
Triad Select Herbicide will not control Poa Annua.
For warm season lawns, Image Kills Nutsedge Concentrate (small lawns) or for larger lawns, Certainty Herbicide - 1.25 oz. or Negate 37WG Herbicide (Zoysia or Bermuda only).
For cool season lawns, poa annua is so closely related to cool season turfgrass that the best option is to spot treat with a non selective such as Roundup QuikPRO - 5 x 1.5 oz. packs and then reseed any barespots after 2 weeks if needed.
Please view our Poa Annua Treatment Guide for more information.
