St. Augustine is very sensitive turf species and torpedo grass is very hard to treat. We apologize, but we are not aware of a product that will treat torpedo grass and not harm St. Augustine turf. You may want to consider spot treating with RoundUp and then reseed/resod the treated areas.
With the Roundup QuikPRO this product generally will start working within seven days of application. The type of weeds sprayed will depend on how long they take to die.
Unfortunately, most of the herbicides will only suppress the torpedograss for a short time, but will not kill it completely. It is recommended to spot treat the torpedo grass with a non-selective herbicide such as Round Up Quick Pro and then re-seed or re-sod in those areas.
Roundup QuikPRO does come with a surfactant in the formulation. There is no need to add an additional surfactant.
Unfortunately, we do not have a selective herbicide to kill carpetgrass in another turfgrass. You can use a non-selective herbicide such as RoundUp QuikPro to spot treat the carpetgrass and then reseed or resod as needed in any bare spots.
You will need to wait at least 2 weeks to plant any type of seed after using Roundup QuikPRO - 5 x 1.5 oz. packs.
Once mixed the shelf life of Round Up Quick Pro is only 24 hours so any mixed solution would need to be used in that time frame for effectiveness and to avoid any issues with clogging or corroding your sprayer.
Yes, Turf Mark Blue can be used with Roundup QuikPRO - 5 x 1.5 oz. packs to make the spray visible when applying
Roundup QuikPRO is a water-soluble granule.
Unfortunately, there are not a lot of options out there for removing bermuda grass from bahia lawns, as these are very similar grasses. Typically, anything that will kill the bermuda will also harm the bahia. It is usually recommended to spot treat the bermuda as much as possible with a product like Roundup QuikPro, and then replant with bahia in those areas in a couple of weeks when the bermuda is gone.
Each 1.5 oz. pack of Roundup QuikPRO makes 1 gallon of spray solution. For most applications, 1 gallon of mixed product will cover 1,000 square feet.
You can use Round Up QuickPro at the highest listed usage rate to help eliminate bamboo. You will be required to cut the bamboo down to a short stump and then apply the Round Up QuickPro. It can take several applications to achieve the desired results.
