GrazonNext HL Herbicide is not labeled to control chufa which appears to be in the sedge family. That being said we would recommend testing over a small area before a full broadcast just to be sure.
Per the product label for GrazonNext, "Manure from animals that have grazed forage or eaten hay harvested from treated areas within the previous 3 days may only be used on pasture grasses, grass grown for seed, wheat and corn."
New cereals and corn can be planted one year after treatment.
Please refer to the product label for full application instructions and precautions.
GrazonNext HL Herbicide is a post-emergent herbicide so it can be used any time the weeds are in an actively growing state. If the weeds are apparent now, then you can use the product now to try and eliminate them. The rate range for GrazonNext HL Herbicide is 1.2 to 1.5 pints (19 to 24 fluid oz) product per acre. Please provide details on your application for specific information. Thank you!
Since GrazonNext HL is labeled for use in grazing areas, you can allow chickens and other livestock to return to the area once the application is dry. Be sure you read all restrictions and precautions on the label before using this product.
GrazonNext HL Herbicide is not directly labeled to kill fruit trees. However, an application could damage them and you would have to discard the fruit for over a year. We would recommend keeping applications outside the dripline of the trees.
There are no restrictions for when you can allow animals to graze on areas treated with GrazonNext Herbicide. We would always recommend waiting for the application to dry completely before allowing animals to re-enter a treated area.
As long as you apply on a non windy day to limit drift of GrazonNext HL Herbicide and do not spray the corn directly or allow overspray to contact it, there should not be an issue applying to the fenceline around a corn field.
GrazonNext HL Herbicide is not labeled for use on millet. NuFarm Weeder 64 would be a better option for pigweed and other broadleaf weeds and is safe over millet as directed on the product label.
Unfortunately we are not always given an exact reason as to why a product like GrazonNext HL Herbicide is restricted in certain states. Usually it has to do with continual misuse of the product resulting in hazards to streams, lakes, public water systems, etc. You may contact your states Dept of Agriculture or the manufacturer Dow AgroSciences at 317-337-3000 for more information.
Unfortunately the GrazonNext HL Herbicide is not labeled to get rid of chamberbitter. If you need a pre or post-emergent herbicide, please let us know what type of turfgrass you have and how much area you are treating so that we can make an appropriate recommendation for you.
