For torpedograss, Quinclorac 75 DF Herbicide is advised to be applied at the rate of 0.245 oz in 1 gallon of water per 1000 sq ft doing 3 sequential applications at 14-21 day intervals. Per the product label, the addition of a Methylated Seed Oil Surfactant is needed for best results at the rate of 2 tbsp per gallon of water or 1.5 pints of MSO per acre. The timing can vary when weeds will start to show signs of dying or when they will die off completey when applying a post emergent. This can vary due to the weather conditions, the type of weed it is, how established the weed is, the specific active ingredients and the rates applied. Generally we advise to allow 1 to 3 weeks to begin seeing results before any follow up applications.

The manufacturer of Quinclorac 75 DF Herbicide suggests not storing diluted solution for more than 24 hours to avoid losing efficacy. It would not be tank mixed with Q4 as it contains quinclorac as well and does not need a surfactant. Per the product label: You should be able to safely mix the Quinclorac 75 DF with 2,4-D, triclopry, MCPA, MCPP, Three way products or other broadleaf herbicides. 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.
