Malathion 57% Insecticide

Malathion 57%, manufactured by Control Solutions Inc., is a highly concentrated insecticide that protects crops and other vegetation from various plant-destroying insects.

Its active ingredient, malathion, is an organophosphate that kills insects by damaging their nervous system, causing them to die within minutes.

Malathion 57% Insecticide can be applied to grass crops, trees, vegetables, and fruits to control aphids and more.

Tools Needed

You will need a backpack sprayer, handheld pump sprayer, or a professional skid sprayer to make applications.

This product is primarily used with a professional skid sprayer or boom sprayer for large croplands.

For small fly control applications, we recommend a 1-gallon pump sprayer.

How to Use

• Step 1: Determine how much Malathion 57% Insecticide to use by measuring the square footage of the treatment area. Do this by measuring the treatment areas' length and width in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres). The amount of Malathion 57% insecticide you will need depends on the type of crops you are treating. This amount can vary from 1 to 8 pints of Malathion per acre, depending on the crop, targeted pest, and harvest time. Refer to the label for the appropriate amount of product and water. For small-volume fly control of home foundations and fence rows, this product can be applied at a rate of 5 tablespoons per gallon of water per 1,000 square feet on painted surfaces and 2 gallons per 1,000 sq. ft. on unpainted surfaces.
• Step 2: Fill your spray tank about three-quarters full with water for proper mixing. Next, add the measured amount of Malathion for your targeted pest and treatment site. Fill your sprayer with the remaining water so the solution is agitated and mixed thoroughly.
• Step 3: Spray vegetation using a medium to coarse spray. Spray with sufficient water to ensure full coverage of foliage but not to the point of runoff. To treat flies along home foundations and fence rows, apply a low to medium spray with a fan-tip setting to ensure even coverage.

Where to Use

Malathion 57% Insecticide can be used on agricultural sites to treat a wide range of fruit and vegetable crops, fruit and nut-bearing trees, and foraging grasses. Malathion can also be used on non-agricultural sites, such as fence and hedge rows, home foundations, Christmas tree plantations, and ornamental trees, shrubs, and plants.

When to Use

Apply on calm, clear days when wind speeds do not exceed 15 miles per hour, and temperatures are over 65 degrees Fahrenheit. Make applications to labeled crops when signs of pest activity appear.

For crop applications, check the label before using this product, as you might have to wait a certain number of days before harvest to apply. For fly control, apply when pests are active.

Safety Information

Malathion 57% Insecticide is safe to use around children and pets when applied according to the product label instructions. Always wear proper personal protective equipment (PPE) when mixing and applying this product.

This product is toxic to aquatic organisms and can contaminate water if wind drifts the spray.

If you are applying near a body of water, do so when there is little wind outside.

Do not apply this product when bees are active in the treatment area.

Special Considerations

Malathion 57% Insecticide is labeled to use primarily with a professional skid sprayer on large land areas with trees, grasses, fruit, vegetable, and non-bearing crop vegetation. Be sure to read the label before applying Malathion, as the harvest time of the crop you want to treat will determine when applications are made.
