Malathion 57%, manufactured by Control Solutions Inc., is a highly concentrated insecticide used to protect 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% can be applied to grass crops, trees, vegetables, and fruits to control aphids and more.

Tools Needed

To apply Malathion 57%, you will need either a backpack sprayer, handheld pump sprayer, or a professional skid sprayer. For large croplands, Malathion is primarily used with a professional skid sprayer or boom sprayer. For small fly control applications, we recommend a 1-gallon pump sprayer.

How to Use

• Step 1: First, you will need to determine how much Malathion 57% you will need for your application. Do this by measuring the targeted area's acreage and the crop or plant you intend to treat. The amount of Malathion 57% insecticide you will need depends on the type of crops you are treating. This amount can vary from 1-8 pints of Malathion per acre, depending on the crop, targeted pest, and harvest time. Please refer to the label for the appropriate amount of Malathion 57% and water to use. For small volume fly control of home foundations and fence rows, Malathion can be applied at a rate of 5 tablespoons per gallon of water per 1,000 square feet on painted surfaces, as well as 2 gallons per 1,000 sq. ft. on unpainted surfaces.
• Step 2: For proper mixing, fill your spray tank about three-quarters of the way full with water. Next, add your measured amount of Malathion for your targeted pest and treatment site. Fill your sprayer with the remaining amount of water, so that 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 for flies along home foundations and fence rows, apply at a low to medium spray with a fan-tip setting to ensure even coverage.

Where to Use

Malathion 57% 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 Malathion 57% 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 Malathion as you might have to wait a certain amount of days before harvest to apply. For fly control, apply when pests are active.

Safety Information

Malathion 57% is safe to use when applied according to label directions. Always wear proper personal protective equipment (PPE) before using this product. Malathion 57% is toxic to aquatic organisms and can contaminate water if wind drifts the spray. If you are applying Malathion 57% near a body of water, do so when there is little to no wind outside. Do not apply this product when bees are active in the treatment area.

Special Considerations

Malathion 57% 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.
