Drive XLR8 Herbicide Crabgrass Killer is only available in a half gallon.
QuinKill Max Crabgrass and Weed Killer uses the same active ingredients as Drive XLR8 and comes in a 16 oz and 32 oz size bottle for smaller quantities.
We typically recommend waiting atleast 24 hours up to 7 days in between applying herbicides and fertilizers to avoid overstressing the turfgrass unless previous applications have shown tolerance to using a fertilizer and herbicide together.
The Drive XLR8 Herbicide Crabgrass Killer does advise that a liquid nitrogen fertilizer can cause some yellowing therefore a small test application would be recommended if deciding to tank mix.
Please review the product label for tank mixing instructions prior to mixing in your sprayer.
Drive XLR8 Herbicide Crabgrass Killer is only a post emergent herbicide and will only kill actively growing weeds. To prevent new crabgrass from germinating, a pre-emergent needs to be applied when soil temperatures are around 55 degrees.
Dimension 2EW is one of the most successful pre-emergents for crabgrass prevention.

How long you will need to wait to make an application of Drive XLR8 will depend on the type of turfgrass you are overseeding with.
Please refer to Table 4 on page 10 of the product label to view the Seeding/Overseeding/Sprigging Timing Chart to help determine the correct timing for your needs.
Drive XLR8 is applied at 63 fl oz in 20 gallons of water to cover 1 acre (add a MSO or equivalent to the mix for more effective control-we offer Duo Stick or DyneAmic).

In California many varieties of crabgrass are resistant to quinclorac, which is the main ingredient used to control it across the country. The active ingredient Quinclorac in Drive XLR8 Herbicide Crabgrass Killer is safe for fescue but resistance is possible.
Q4 Plus which is quinclorac and sulfentrazone together for the crabgrass, or Tenacity which is a completely different active ingredient all together. Tenacity though works bests as spot treatments for post emergent control, and the manufacturer suggests only targeting young crabgrass with it as mature large clumps will take multiple applications or may not see complete control when at that growth stage.
Make sure every spring you are using a pre emergent like Dimension 2EW or Pendulum 2G Herbicide to prevent the crabgrass seeds from germinating so you do not have to treat for it later in the growing season. Pre emergents should go down right at or just before soil temps reach 55 degrees consistently.
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 so that the product has sufficient time to dry before temperatures get above this range.

Drive XLR8 can take up to 3 weeks to see full results on targeted weeds and a second appliation may be needed for more established weeds. Keep in mind, for best results, applications should be applied to listed weeds when they are young and actively growing and temperatures are between 65-85 degrees. For actively growing crabgrass, Drive XLR8 is mixed at 1.45 fl oz per 1000 sq ft along with adding 0.16 - 0.48 fl. oz Duo Stick per gallon of water. If only treating 500 sq ft, you would cut those rates in half, mixing Drive XLR8 at 0.72 fl oz in one gallon of water along with the 0.16 to 0.48 fl oz of Duo Stick Surfactant.
It is important to follow the recommended rates per the product label and not overmix or overtreat to avoid burning or injury to your turfgrass. You may see some discoloration, burning or wilting of your turfgrass as the rate applied of 2 fl oz Drive + 1 fl oz Surfactant over 500 sq ft is double the labeled rate.
Drive XLR8 Herbicide Crabgrass Killer is not recommended to be applied using hose end sprayer as it is difficult to regulate the amount of water coverage and to ensure adequate water volume is coming out to evenly and thoroughly distribute the recommended 1.45 fl oz per 1000 sq ft mix rate.
Per the product label, use at least 20 gallons of water per acre or 0.5 gallons of water per 1000 sq ft at a low pressure setting of 20 to 40 psi to provide uniform spray distribution. A methylated seed oil surfactant is also recommended to be tank mixed with Drive XLR8 for best results.

Drive XLR8 is for turfgrass areas only and cannot be used on ornamentals, flowers, or landscape beds where Bifen IT is also labeled for lawns but also commonly applied to treat insects as a foliar spray to bushes, trees, shrubs, etc. Be mindful that you are only applying your herbicide in the correct areas.
Herbicides and insecticides can be tank mixed together in a tank mix as long as there are no tank mixing restrictions on the product label for the other product that you are using. We recommend performing a small jar test for compatibility any time you are using two new products together for the first time.
Please view our Tank Mixing Herbicide Video showing how to do a “Jar Test”.

Drive XLR8 Herbicide Crabgrass Killer requires the use of a methylated seed oil surfactant for best results and one is not required when using Dismiss so it would not be recommended to tank mix the products together in a single application.

Drive XLR8 is not labeled to treat panic veldt grass. Using a glyphosate product (Roundup) applied as a foliar spray at 2 percent concentration with added surfactant was shown to be effective against Panic-Veldt. Using a product like Roundup QuickPRO will give you both treatments in one. QuickPRO has two active ingredients: 73.3% glyphosate and 2.9% diquat. The addition of diquat, along with the surfactant, gives you even faster burndown. It controls broadleaf and grass weeds, or woody brush and trees - roots and all.
Using a chemical method along with chemical treatment, will help with control unless you are able to to identify where this weeds originates. Regardless of the method used, more than one year of treatment will be necessary, due to its extensive seedbank, the persistence of which is unknown.
