Tools Needed

To apply Monterey Neem Oil Insecticide you will need a hand-pump sprayer, backpack sprayer or hose-end sprayer.

How to Use

• Step 1: Identify the areas where preventive treatment or where immediate treatment is needed. A typical application will use 2 to 4 tablespoons (1 to 2 fl. oz.) of Monterey Neem Oil per gallon of water.
• Step 2: Shake the container well before using. Pour in half of the amount of water into sprayer tank, add measured amount of Monterey Neem Oil, and fill the rest of the way with remaining half of water.

Do not add water for hose-end sprayer as water will automatically mix with the product as you spray.
• Step 3: Point the nozzle of your sprayer towards infested plants and areas and spray in a sweeping motion until all surfaces of the plant area wet including the top and bottom of leaves. Respray the area every 14 days for continued control of diseases and insect infestations.
