Physiological Effects of Petroleum Oil Sprays on Citrus

Abstract

A discussion of the injurious effects of petroleum spray oils on citrus is given. The 2 main factors are: the chemical burning by the unsaturated hydrocarbon molecules or other toxic molecules and the result of plugging of intercellular spaces and the surrounding of the plant cells with oils which prevent the movement of gases such as CO2 and O2 out of and into the cells.
