Tools Needed

To apply Atrazine a backpack sprayer, handheld pump sprayer, hose-end sprayer or professional skid sprayer is needed. When applying Atrazine 4L to residential lawns, a handheld pump sprayer or backpack sprayer is recommended.

How to Use

• Step 1: To figure out how much Atrazine 4L you need, you will need to determine the treatment area. To do this, multiply length x width to get the total square footage to be treated. Atrazine 4L's label recommends applying the product at a rate of 1.5 fl. ozs. per 1,000 square feet in a gallon of water or 4 pints per acre in 15 gallons of water. For example, if you have a 3,000 square foot area to be treated, you would need 4.5 ozs of Atrazine mixed with 3 gallons of water. If you need to treat 3 acres, you need 12 pints in a minimum of 45 gallons of water.
• Step 2: Start the mixing and agitation process and pour the correct amount of product into the spray tank. Fill the spray tank with water until it is about 90% full and then add emulsifiable oil, oil concentrate or tank-mix herbicide(s) after the product is thoroughly mixed. The type of crop and land areas being treated will determine the required amount of additives needed and will also determine if the treated area requires irrigation. Fill the rest of the tank with the remaining amount of water and agitate to ensure it is well-mixed.
• Step 3: Apply the mixture to designated areas, preferably in a fan nozzle spray setting for even coverage until all or most of the solution is used.
