As long as you perform a tank mix test first to check for compatibility between the two chemicals, you can tank mix the Quinclorac 75 DF and the Tebuconazole fungicide to apply together. You will want to mix the Quinclorac into the tank first since it is the dry chemical that will need more time to dissolve into the water before adding the other chemical.
It is required to mix Quinclorac 75 DF with a MSO surfactant, but we recommend reading the product label to see if the product can be tank mixed with any type of fertilizers.
Quinclorac 75 DF is labeled for several types of foxtail as well as field bindweed. Be sure to review the full product label for complete mixing and application instructions.
Since the Quinclorac 75 DF is not typically spread in a hydroseeder, we recommend reaching out to the manufacturer, Quali-Pro for more information. Their phone number is 800.242.5562.
Quinclorac 75 DF would harm ground cover, including Periwinkle. We would recommend Grass Out Max as it is safe to kill grassy weeds in flowers, shrubs, broadleaf crops or other broadleaf plants.
Quinclorac 75 DF is not labeled to control spurge at all. We would recommend Q4 Plus Turf Herbicide instead with also contains quinclorac and 3 other actives for broader weed control.
No, Quinclorac 75 DF Herbicide is not labeled to be applied to Bahiagrass, carpetgrass, St. Augustinegrass, Centipededgrass, Dichondra or lawns or turf where desirable clovers are present.
Please review the product label for more information and the Restrictions Section on page 7 for more limitations.
Per the product label, if soil is dry before a Quali-Pro Quinclorac 75 DF application, irrigation of the turfgrass may improve weed control. For best results, DO NOT water or irrigate for 24 hours following the application. Irrigate the treated turfgrass with atleast ½ inch of water 2 to 7 days after application if no rainfall is received within that period.
Depending on how many square feet the 4 gallons of mixed solution covered, you may need to do a repeat application for better weed control. Per the product label, the mix rate is 0.73 oz per 1000 sq ft or 1 tbsp per gallon of water.
Quinclorac 75 DF Herbicide is not labled to kill chickweed. We do have alternative products here depending on your turfgrass type.
The product label for Quinclorac 75 DF does not restrict applications during transition. However, since Quinclorac 75 DF may yellow hybrid Bermudagrass, and Bermuda in general is more sensitive during transition, we recommend that you wait until the Bermuda is fully green before applying this herbicide. Quinclorac will be most effective when air temperatures are around 60-85 degrees and there is good soil moisture, so those conditions may not exist until the Bermuda is fully green. You can add some chelated iron or liquid nitrogen fertilizer when using Quinclorac 75 DF on hybrid Bermuda to help reduce risk of discoloration, per the product label.
Quinclorac 75 DF is used at the rate of 0.367 oz per 1000 sq ft when applied as a broadcast appliation or spot treatment in a minimum of 0.5 gallons of water. If you are just spot treating with a specific amount of water, for example 1 gallon, you would use the 1 tbsp per gallon of water. So if you are treating the entire lawn, you could use 1.25 oz in 4 gallons to treat the entire lawn.
The manufacturer of Quinclorac 75 DF Herbicide suggests not storing diluted solution for more than 24 hours to avoid losing efficacy.
Quinclorac 75 DF should be used with a Methylated Seed Oil (MSO) surfactant such as Prime Source Duo Stick. Generally speaking, triclopyr does not require a surfactant and is normally applied in cooler temperatures whereas quinclorac is applied in warmer temperatures. Using triclopyr with an MSO may be too harsh on any desirable turfgrass. There is a specific window (time frame) these types of products could be applied if they were to be applied together for a situation labeled safe for that type of use. We would recommend contacting your local cooperative extension office for more information on the best timing to treat the specific weeds in your specific region.
Quinclorac 75 DF Herbicide comes included with a measuring device that should assist with the precise amount, if you do not have the measuring cup, you will need a scale to measure it as it is done by weight and not volume as a dry product. Please refer to the product label for application rates and instructions, and use as directed.
If the Marathon turgrass you have is a Tall Fescue seed blend then yes, Quinclorac 75 DF Herbicide would be safe to apply as Tall Fescue is a tolerant turfgrass per the product label. For spot treatment of weeds, it is recommended to use a MSO surfactant for better adhesion and faster burndown of weeds.
Quinclorac 75 DF should not be applied to exposed feeder roots of trees, ornamentals or within the dripline of trees and other ornamental species.
After applying Quinclorac 75 DF Herbicide crabgrass will first discolor and then over a long period of time start to breakdown. You will have discolored spots for some time unless you choose to remove the dead crabgrass physically.
You should be able to safely mix the Quinclorac 75 DF and a 2,4-D product to get a wider range of weed and weedy grass control with no issues. As with any chemical mixture, be sure to do a tank-mix test first to make sure no clumping or mixing issues occur and spot test a small area to be sure no undesirable effects occur from the mixture and use. Always follow the most restrictive label of the two for use and refer to each product label for complete instructions regarding tank mixing.
Quinclorac 75 DF should be applied when the ground is not frozen and rainfall/snow is not expected for more than 24 hrs. You want to treat when the weeds when they are actively growing for the best results. We recommend to make the application in the cooler times of the day also when temps are between 65-80 degrees.
