Summary

Field experiments were carried out to study the effect of a highly purified paraffinic oil on the efficiency of some insecticidal sprays used for the control of thrips and cotton leafworm. The results show that the oil used separately at the rate of 7·51/ha significantly reduced the population of thrips, but oil-insecticide combinations were superior to oil or insecticides applied alone. The mineral oil increased the efficiency of candidate insecticides against both thrips and cotton leafworm two-fold or more.
