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, and smooth skinned caterpillars.
[edit] Recipe and Directions
For the concentrate mix 1 cup of cooking oil with 1 teaspoon of dish washing liquid and 1/2 cup of water. To prepare the concentrate for use, dilute 40ml in 1 litre of water, mix the spray well and spray pests, and plants about once a fortnight. Avoid spraying on palms, ferns, or plants with hairy foliage and do not spray in hot weather as this can cause leaf burn.
