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 Herbicide would not be safe to use in brassica fields, both because it would harm the plants as well as not being labeled for use in areas with edible vegetation. Grass Out Max and a Non Ionic Surfactant can be used over the top of brassicas and many other edibles to control grassy weeds growing within them, but we cannot say what the safety to Switchgrass would be. Its not labeled to target it, but it's also not labeled as safe or tolerant to the product, so you would need to test a small area for tolerance before making broader applications. We do not carry any herbicides for broadleaf weeds in those settings, you may need to reach out to your states Department of Agriculture for farming recommendations.
