The application of Dismiss Turf Herbicide will need to stay outside of the drip line of any fruit trees or any edibles to avoid uptake by the tree roots.
For weeds under the canopy or within the drip line of fruit trees, it s recommended to spot treat the weeds directly with Avenger Weed Killer Concentrate as this is a non selective herbicide.
Dismiss Turf Herbicide has no temperature restrictions unless it’s above 90 degrees. But the weeds would need to be actively growing in order for the proudct to be effective, and that is usually when temperatures are above 55 degrees. For control of bittercress in your fescue lawn at lower temperatures, you can use something with an Ester formula like SpeedZone. Keep in mind that the weeds would still need to be growing for best results.
Dismiss Turf Herbicide is labeled to kill Henbit and labeled safe for fescue and Bermudagrass. It's a post-emergent and will kill the weeds that are already popping up. For better control of Henbit, you can make a pre-emergent application using Prodiamine 65 WDG in the summer, fall or winter before weed seeds germinate.
We recommend using a product that specifically states bahia grass will tolerate it. Please look in to Fertilome Weed Free Zone. This product will treat many different types of broadleaf weeds and bahia grass will tolerate it. We recommed that you treat with SedgeHammer for the treatment of nutsedge in your lawn. Please read the product labels for both products prior to application for more detailed information.
Fertilome Weed Free Zone Product Label
Fertilome Weed Free Zone-Product Label States the following:
'Do not apply directly to or near water, storm drains, gutters, sewers, or drainage
ditches. Do not apply within 25 feet of rivers, fish ponds, lakes, streams,
reservoirs, marshes, estuaries, bays, and oceans. Do not apply when windy.
To prevent product runoff, do not overwater the treated area to the point of
runoff or apply when raining or when rain is expected that day. Rinse applicator
over lawn or garden area only.'
Dismiss Turf Herbicide can be applied anytime the target weeds are actively growing and healthy, just avoid spraying during high temperatures. You may need to apply in the morning or evening.
You could potentially apply Dismiss Turf Herbicide with a pre-emergent herbicide as long as neither label prohibits such use and both can be used in the same areas. However, you want to be sure that you are applying your products at the optimal time for the weeds you are targeting. Pre-emergents must be applied before weeds germinate, which is usually when soil temperatures are between 50-55 degrees. Post-emergent herbicides will be most effective when target weeds are young and actively growing; for most herbicides this is in the range of 60-85 degrees. Be sure to calibrate products properly, and if you are mixing two products that have not previously been verified to work together, it is best to do a small jar test for compatability first.
Dismiss Turf Herbicide is only a post-emergent herbicide, so it will not affect any seed heads that possibly split and have not yet germinated at the time of application and before the target plants have died. You may want to take the label rates for Table 2 (sedges) and split your application for optimal control of weeds like nutsedge and kyllinga.
Both Dismiss and Fertilome Weed Free Zone are excellent to treat cudweed and can be used on Centipedegrass. We do suggest alternating your active ingredients to avoid resistance buildup.
