Acetone is a normal constituent of the environment and produced endogenously in plants, animals and humans. In search of safe natural crop protection materials, potential of acetone for use as a fumigant against three major greenhouse pests in Antalya, Turkey, the carmine spider mite Tetranychus cinnabarinus (Boisd.), the cotton aphid Aphis gossypii Glov., and the western flower thrips Frankliniella occidentalis (Pergande), was demonstrated. Laboratory assays were carried out by exposing the test mites and insects to acetone vapours. The time required for 99 % mortality in the adults of T cinnabarinus A. gossypii and adults and larvae of F occidentalis was 95.5, 67.6, 34.7 and 34.3 h, respectively, at 80 mul acetone/l air. T cinnabarinus eggs were the most tolerant stage and a much longer exposure period, 229.1 h, was required. No damage was detected in eggplant, pepper and tomato seedlings exposed to 80 mul acetone/l air for 96 It and carnation seedlings for 72 h. No health and environmental risks are anticipated from use of acetone for fumigation. Acetone seems a promising fumigant in a number of places including greenhouses where higher standards of worker and consumer safety are sought.
