White oil
From Wikipedia, the free encyclopedia
White oil is a home made insecticide spray used for controlling a wide range of insect pests in the garden. The spray works by blocking the breathing pores of insects causing suffocation and death. It is effective in the control of aphids, scale, mealybug, mites, citrus leaf miner and smooth skinned caterpillars.
"White oil" is also an alternative name for mineral oil.
Recipe
The quantities vary depending on the source, but a typical mixture is 4 parts of vegetable oil to one part of dish-washing detergent (for washing by hand). Blend in a mixer until homogeneous and store. Dilute 1:50 with water for use, spraying leaves from above and below.
