Malathion is an ingredient used in agricultural insecticides. You will find it listed under the active ingredients section of an insecticide product label. If you are experiencing a problem with insects attacking your fruit trees, purchase a product with malathion in it to get rid of them. Malathion successfully kills aphids, Japanese beetles, mealybugs and spider mites, among others.
Put on a long-sleeved shirt, and a pair of long pants before using the insecticide with malathion. The Gowan Company also recommends wearing socks and shoes. This will prevent the chemical from accidentally splashing on your skin.
Put on a pair of chemical-resistant gloves, a mask and a pair of goggles.
Pour 1 1/4 pt. of insecticide containing malathion in a garden sprayer.
Add 12 gallons of water to the garden sprayer and mix the two ingredients together.
Spray the insecticide directly onto the foliage, as well as the fruit on your fruit tree. If your fruit tree is tall, you may need a ladder to reach the top of the tree. It is easier if you start at the top of the tree, and work your way down.
