Is Blindside safe to use on fescue lawns during fall overseeding or on new fescue growth?
JG on Aug 23, 2016
BEST ANSWER: Yes Blindside is safe for Fescue Lawns, *Blindside Herbicide has demonstrated tolerance on both cool and warm season turfgrasses. However, not all varieties have been evaluated. Turfgrass managers desiring to treat newly released varieties should first apply Blindside Herbicide to a small area prior to treatment of larger areas.
If turf discoloration occurs after an application of Blindside Herbicide turfgrass will
generally recover with new growth. Discolored leaf tissue will be removed with mowing. To reduce potential for discoloration, do not apply Blindside Herbicide on turfgrass that is weakened by weather, mechanical, chemical, disease or other related stress. Maintain proper cultural practic
Can I use Blindside in the early fall to prepare my lawn for seeding in the early spring?
Mark D on Sep 4, 2017
BEST ANSWER: Blindside Herbicide is a selective post- emergence herbicide which controls
annual grasses, broadleaf weeds and sedges in established turf
areas including, but not limited to, residential, commercial and institutional
lawns, athletic fields, commercial sod farms, golf course fairways
and golf course roughs.
Blindside Herbicide is formulated as a WDG (Water Dispersible
Granule) containing 0.66 lb of active ingredient per pound of product. Blindside Herbicide is absorbed by shoots, foliage and roots.
A post emergent application of Blindside Herbicide is improved when
adequate soil moisture is present at application. Best weed control
results will be obtained when no rainfall or irrigation occurs within 24
hours after application. If no rainfall or irrigation occurs within 7 days
after application of Blindside Herbicide in the amount of 0.5 inches, then
irrigation of at least 0.5 inches is recommended.

Application to reseeded, overseeded or sprigged areas:
Reseeding, overseeding or sprigging of treated areas within one (1)
month after application of this product could inhibit the establishment of
desirable turfgrasses. A spring application of Blindside Herbicide may
aid in overseeded ryegrass transition in Bermudagrass, transition efficacy
may be species depentent. Overseeding of bermudagrass with
perennial ryegrass at six (6) to eight (8) weeks after an application can
be done if slight injury to perennial ryegrass can be tolerated. Best
results are obtained for reseeding or overseeding when mechanical or
power seeding equipment (slit seeders) are used to give good seed to
soil contact and proper soil cultivation, irrigation and fertilization practices
are followed.

Is this safe on an older st Augustine grass lawn that has a lot of annual bluegrass in it when the st Augustine is just now beginning to grow?
Harold E on May 1, 2018
Can you mix Blindside with bifen? This would really save a ton of time. Thank you in advance for your help.
Jim on Mar 1, 2017

It is not recommended to mix any herbicide with any insecticide together. We actually recommend using two different sprayers one for the insecticide and one for the herbicide. You can spray your blindside and the bifen on the same day.
Is this a concentrate that one mixes with water?

Worked well
Waited until I had at least 2 days with no rain. Applied and saw results the next day. Very happy with results at this point.
