Tools Needed

For Hi-Yield 38-Plus you will need a type of hand held sprayer, back pack sprayer, or hose end sprayer to treat a large area.

How to Use

• Step 1: Determine the size of the area to be treated with the Hi-Yield 38-Plus by measuring the area's length and width, and then multiplying them together (length X width = square footage). The mix rates will vary depending on what you are treating for, but typically you will use between 0.4 fl. oz. to 0.8 fl. oz. of Hi-Yield 38-Plus per 1,000 sq. ft.
• Step 2: To mix, fill your sprayer halfway with water, pour in your measured amount of product based on your treatment area, and then fill your sprayer the rest of the way with water. Shake your sprayer to ensure an even mix.
• Step 3: To treat the perimeter of your residential building, first apply a 6 to 8 ft. wide band of soil around the perimeter of home then treat the foundation wall to a height of 2 to 3 ft. Use a spray volume preferably with a hose end sprayer between 2 to 10 gallons of hi-yield 38-plus with 0.5% emulsion per 1,000 sq. ft. For treating wood destroying pests, use 0.5% emulsion to fill in voids and damages in the spaces between the wood frames and structures of the foundation. For most broadcast applications, you will want to apply a coarse spray application that evenly covers plant surfaces, spraying to wet but not run-off. For mound drench treatments, you will apply with a type of hand held sprayer to easily apply a 4-foot diameter circle around the mound until it is completely wet.
