Tools Needed

To use Weedar 64 Herbicide, a backpack sprayer, handheld pump sprayer, or skid sprayer is needed. We suggest using a handheld pump sprayer when making spot treatment applications and small ornamental turf and lawn areas.

How to Use

• Step 1: Determine how much Weedar 64 Herbicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length x width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acre). For ornamental turf areas (excluding grasses grown for seed or sod farms), apply 2 to 3 pints of Weedar 64 Herbicide in 50 gallons of water per acre. For conservative reserve program areas (including perennial grasslands not in agricultural production), use 1/2 to 2 pints of product in 3 to 10 gallons of water per acre for annual broadleaf control or 2 to 4 pints of product in 20 to 100 gallons of water per acre for biennial and perennial broadleaf weed control. For spot treatments with a handheld sprayer, apply 1.5 to 3 fl. oz. of product in 1 to 3 gallons of water per 1,000 sq. ft. However, the spot treatment varies in certain application sites. For this reason it would be best to refer to the product label for specific application rates and restrictions.
• Step 2: Fill your sprayer halfway with the required amount of water. Add the correct amount of Weedar 64 Herbicide to the spray tank and mix by shaking the spray tank. It is also suggested to mix Weedar 64 Herbicide with a surfactant to enhance weed control, so this is the time to add that in as well and agitate the sprayer.
• Step 3: Apply the Weedar 64 Herbicide mixture to areas where unwanted vegetation is currently growing, preferably on a fan spray setting to ensure even coverage. 

Where to Use

Weedar 64 Herbicide is for the control of many broadleaf weeds in asparagus, blueberries, cereal grains, corn, cranberry, fallowland and crop stubble, orchard floor, rice, sorghum, soybeans, strawberries, sugarcane, forests, rangeland and established grass pastures, in non-crop areas including lawns, ornamental turf, drainage ditchbanks, fence rows, rights-of-way. For aquatic use, Weedar 64 Herbicide may be used on banks of canals and irrigations ditches as well as ponds, lakes, reservoirs, marches, bayous, drainage ditches, ricers, and streams that are slow-moving.

When to Use

For best results, Weedar 64 Herbicide should be applied during warm and calm weather conditions when targeted vegetation is actively growing, before adverse conditions like cold or extreme heat are present.

Safety Information

Weedar 64 Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product. Do not allow people or pets to enter treated areas until 48 hours have passed after application.

Special Considerations

Any weed population may contain or develop plants naturally resistant to this product and other similar products. To mitigate this, alternating products is necessary when repeated use of herbicides are used.
