Drive XLR8 Herbicide should be applied where there is no rain in the forecast for at least 24 hours. Depending on how long after applying and how much rain you received, you may need to reapply again.
As long as both products do not contain the same active ingredient, and both have labels that allow tank mixing in general then you should be able to. Per the Drive label: The most restrictive labeling applies with any tank mix.
To increase spectrum of control of broadleaf and other weeds, Drive XLR8 may be tank mixed with 2,4-D, Triclopyr, and other broadleaf herbicides. Make sure to do a tank mix test first for any clumping or discoloring before applying to the lawn.
Please note: Drive XLR8 requires the use of a methylated seed oil surfactant for best results. Since most broadleaf weeds killers do not require the use of a surfactant and the use of a surfactant can reduce selectivity on tolerant turfgrasses causing injury to the lawn.
If tank mixing, we recommend doing a small test spot spray application to target weeds to test for any discoloration or injury before broadcasting over the entire lawn area.
We would not recommend tank mixing Triplet or Battleship with Drive XLR8 Herbicide Crabgrass Killer.
Drive XLR8 Herbicide Crabgrass Killer requires the use of a methylated seed soil surfactant to effectively kill actively growing weeds. The Triplet Selective Herbicide and Battleship 3 do not recommend the use of a surfactant therefore tank mixing these 3 together could damage your turfgrass.In order to ensure you are using a sufficient volume of water, you will want to use a 1-2 gallon hand pump sprayer to apply the mixed solution of Drive XLR8 Herbicide Crabgrass Killer (1.45 oz per 1000 sq ft) and the 2 teaspoons of DyneAmic Surfactant.
Water is acting as the carrier therefore you want to be sure you are using enough water to evenly and thoroughly cover 1000 sq ft.
View our How to Apply Drive XLR8 Crabgrass Killer Video for more information.
You want to make sure to use the diluted solution within 24 hours of mixing. The shelf life of Drive XLR8 Herbicide Crabgrass Killer undiluted is 3 years.
Drive XLR8 Herbicide can safely be used on your Kentucky Bluegrass if applied as directed per the product label. Be sure you are using sufficient volumes of water to evenly spray the 1.45 oz of Drive over 1000 sq ft.
The product label does advise in the footnotes below Table 1 on page 8 that “Yellowing that occurs on these species can be reduced by the addition of chelated iron or sprayable soluble nitrogen fertilizer.”
To avoid any turf damage, Drive XLR8 should be applied when temperatures are between 65-85 degrees. It would be best to apply in the early morning or in the evening when temperatures are at their lowest so that the product has sufficient time to dry before temperatures get above this range. If temperatures are above 85 degrees, you should wait to apply the product when temperatures are lower. Please be sure to review the product label for more information and complete application instructions before use.
Drive XLR8 is rain fast within just an hour or so, so if you had several hours between application and when the rain occurred you should be good to go without need for reapplication. You will however need a surfactant mixed in if you want to see control over the crabgrass, so on your follow up applications you need to add about 2 tsp of a MSO type surfactant, such as Duo Stick.
Drive XLR8 Herbicide Crabgrass Killer should only be applied to fully established turf grass, and used as directed on the manufacturer's product label. Generally, a lawn is considered to be fully established after it has been mowed at least three times.
If you have not had a soil analysis done on the lawn, we would recommended doing one to determine what nutrients your lawn has or may need. This can help with establishing new turfgrass and overall lawn health.
Please view our Soil Test Kits or contact your County Extension Office for assistance with a soil analysis.
