Horticultural Oil is a mineral oil-based insecticide to be used as a dormant and/or summer spray. It is an odorless, nonstaining organic control especially designed for usage in environmentally sensitive areas. Can be used to control some diseases as well.
The mode of action for Horticultural Oil is suffocation of eggs, larvae and nymphs of insects, mites and adults of soft-bodied insects. This mode of action necessitates total spray coverage. As a fungicide this product interferes with the attachment of the pathogen to the host and acts as a suffocant.
This product may be used to control mite and insect pests in the egg stage, including: spider mites, eriophyid mites, armored scale, soft scale, mealybugs, psyllids, whiteflies, aphids, leafrollers, leaftiers, webworms, cankerworms, plant bugs, leafhoppers and adelgids. This product will kill other immature forms if spray covers the insect.
Horticultural Oil Mixing Instructions
Mix 2.5 – 5.0 tablespoons per gallon of water and spray as needed. Use enough spray solution to completely penetrate the leaf canopy and cover both top and bottom of all of the leaves until wet without significant runoff. Most mature standard trees will require 3 to 4 gallons of spray solution per tree although citrus trees may require 8 to 15 gallons of spray solution per tree. Fruits, vegetables, and ornamentals generally require 1 to 2 gallons of spray solution per 1,000 sq. ft.
