Product Overview

Adama Direx 4L Herbicide is an excellent herbicide that provides selective control of weeds in crops and nonselective weed control on non-cropland sites. Contains diuron as its active ingredient which is mainly used in targeting and controlling weeds and mosses on non-crop areas and agricultural crops. It can be applied pre-plant, pre-emerge, or post direct, offering flexible application methods. The Adama Direx 4L Herbicide is specially formulated as a liquid flowable so it is easy to handle and convenient to use. It is proven to control weeds including crabgrass, pigweed, ragweed, wild mustard, pennycress, foxtail, horseweed, pokeweed, annual ryegrass, chickweed, and johnsongrass. Highly effective in managing Palmer pigweed or horseweed in cotton that is resistant to glyphosate. This herbicide is long-lasting, offering high-quality control of up to three and a half weeks. Safe to use because it is noncorrosive to equipment, nonvolatile, and nonflammable. For best results, apply the herbicide within two weeks before rainfall since moisture is required in activating the herbicide. Available in a 2.5-gallon jug container.

    This is my first time using this but it was highly recommended by a yard professional. I got my yard sprayed and then had nearly a foot of snow and a over a week of below freezing weather so we will see later on this year.

How much water is needed to mix 0.8 to 2.4 quarts of Adama Direx 4L Herbicide per acre for my application?

The recommend volume of water per acre for Adama Direx 4L Herbicide ranges from a minimum of 25 gallons to 100 gallons of water per acre depending on the application site and what state it is being applied in.

At a minumum, you will mix  0.8 to 2.4 quarts in 25 gallons of water per acre. Determine how much water it takes to cover 1 acre, this could be more than 25 gallons of water and that is fine. If treating less than 1 acre, determine the water volume needed to cover 1000 sq ft and adjust for that square footage.

Please view our How to Calibrate Your Sprayer Video that goes in depth on how to determine the amount of water volume needed per 1000 sq ft.
