For bulk application, such as use on yards or in large gardens, herbicides are often sold in concentrated form. Before you can use a concentrated herbicide, you must mix it with water. Herbicides that are sold as tank mix combine two or more herbicides, or combine an herbicide and fungicide, that can be mixed in the tank of a tank sprayer. Tank mixes are designed to work synergistically to combat a range of problems.
Read all literature that is included with your herbicide to become familiar with warnings and safety precautions. Herbicide poisons that will kill plants are also harmful to humans. Mixing instructions will vary among herbicide brands. The directions will indicate how much water to add to herbicides.
Wear protective clothing when handling and mixing herbicides, including rubber boots, a plastic apron, long sleeves, long pants, plastic gloves, breathing protection and safety goggles. Your skin might absorb the herbicides, so take a shower immediately after mixing or using them. If the herbicide splashes onto your skin, wash it off immediately.
Test the pH of your water before mixing it with herbicides using a swimming pool pH testing kit. Hard water with high pH might reduce the effectiveness of herbicides and cause incompatibility in tank mixes. Use water that is a neutral pH between 6.5 and 7.5 to mix your herbicide.
Measure out the correct amount of all component chemicals and water into measuring buckets with measurements marked on the side of the container. Or pour the component chemicals and water into a holding tank marked with measurements on the side. Always pour the chemicals and water in the order listed on the instructions that are included with the herbicide component chemicals.
Stir the herbicide mix with a stirring rod.
