Southern Ag Vantage Grass Killer is for post-emergent control of perennial and annual grass weeds in non-crop sites, non-food sites, and ornamentals. Southern Ag Vantage Grass Killer is a selective herbicide effective against a wide variety of weeds, but does not control broadleaf weeds or sedges. Basically all grasses are affected by Southern Ag Vantage Grass Killer including grass crops like corn, sorghum, rice, and small grains, as well as, turfgrass and ornamental lawns. In order to control all vegetation you may need to use a broadleaf herbicide.
Vantage grass killer works on thin bladed grasses, like Bermuda, without killing centipede. Using as directed, it does a decent job, with results in about 2 or 3 weeks. The only problem, as anyone dealing with the "devil's weed Bermuda" knows, it is next to impossible to completely eradicate the stuff. This is the best product I have found that at least keeps it at bay and doesn't harm the centipede. You will need to retreat emerging Bermuda about every 2 months or so.
This stuff works quite well on centipede lawns. You must be accurate with measuring. Follow directions exactly on precautions; dress appropriately!!! Works well around flower beds. Again, read directions as to which plants are tolerant to this product.
In North Florida with a centipede grass lawn which has a small area of burmuda grass, using a 3 gallon hand sprayer, how many ounces of VANTAGE should I use per 3 gallons to kill the burmuda grass? And when should I apply it?
You would use 0.5 - 1.4 oz. of Southern Ag Vantage Grass Killer per 1,000 sq. ft (the amout of water is not as important as applying the proper amount of herbicide to the 1,000 sq foot section) for a broadcast application or 2 - 3 oz per gallon of water for spot treatments.
is it safe to use VANTAGE on a centipede lawn during the lawns dorment perion to control bermuda and/or bahia
i have a centipede lawn with localized bermuda and/or bahia infestitation. is it ok to use vantage in the fall/winter when the grasses(including centipede) is dorment ?
While it is safe to use it on your lawn when it is dormant, it will be a complete waste of money and product as it will not kill what is currently there. Post emergent products like Vantage will only kill the weeds you are targeting when they are in an actively growing state and are absorbing nutrients. If they are dormant already, it will not absorb the product at all and will not be affected by it.
Liriope is actually listed as a tolerant shrub to the Vantage Grass killer.
Unfortunately, once the liriope are up and thriving the only way to kill it is to carefully spot treat with a glyphosate product such as Agrisel Gly Pho-Sel Pro. Agrisel Gly Pho-Sel Pro is a non-selective herbicide which means it will kill most types of vegetation including desirable turfgrasses, so care must be used when applying this product to the turf areas.
