Low volume sprays (LV = 50–100 gal/acre total spray) of petroleum oil and pesticides were applied to citrus trees to determine their effect on populations of citrus red mite, Panonychus citri (McGregor), and California red scale, Aonidiella aurantii (Maskell). Selection of LV equipment and its rate of travel, operating pressure, and the size of the nozzle orifices as well as their placement on the equipment was based on spray distribution studies. LV applications of most evaluated acaricides and the petroleum oil fractions effectively controlled citrus red mite. California red scale was not effectively controlled by LV applications of petroleum oils, malathion, azinphosmethyl, and carbaryl, but this scale was effectively controlled by the LV applications of parathion and by certain combinations of oil and malathion, oil and azinphosmethyl, or oil and carbaryl.
