Trying to kill crab grass and some broad leaf weeds

It is not recommended to apply Quinclorac 75 DF or any other herbicide when temperatures above 90 degrees Fahrenheit as this could burn turfgrass. Be sure to apply in the early morning or late evening so that the product has had time to dry before temperatures exceed 85 degrees.

Quinclorac 75 DF should be applied only in temperatures below 85. You should apply in the early morening or late evening on hot temperature days. The product label does state the following regarding crabgrass: Complete control may not be achieved under certain conditions to crabgrass at 2 - 4 tiller stage. In these cases you will need to make a sequential application for control. For best results apply with methylated seed oil either before the second tiller stage or as the weed grass mataures. You should treat whenever the crabgrass has just emerged or after it has matured for best results, whenever this is in your area. You can also check with your local cooperative extension office for the best advice on timing.

Quinclorac 75 DF is not recommended to be used in a hose end sprayer. The first thing you need to know when using an herbicide is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.

You should be able to safely mix the Quinclorac 75 DF with the Speedzone 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. Per the Quinclorac 75 DF product label, only use on fine fescue if its incorporated into a fescue blend as some turf damage or discoloring could occur if its a fine fescue lawn only.

Q

Can Quinclorac 75 be mixed with Trimec?

A

When applying any two herbicides at the same time you will need to do a jar test and check for compatibility and emulsion of the two products. If the Quinclorac 75 DF and Trimec mix well and emulsify after agitation it would be ok to mix and apply them together.
