Influence of spray volume and oil concentration on the efficacy of petroleum spray oil against Myzus persicae (Sulzer) (Hemiptera : Aphididae)
Australian Journal of Entomology 37 (1), 70-73
Abstract: A Potter spray tower was used to assess the efficacy of petroleum spray oils against the green peach aphid, Myzus persicae. Increasing spray volume (1.00-5.65 mL) of C23 D-C-Tron NR resulted in a significant (P < 0.001) increase in aphid mortality when oil deposits were held constant (40 g/cm²). The practical implications of this result are discussed. LC95 (µg oil/cm²) values of 107, 147 and 87 against C20 Total Citrole, C21 Caltex Lovis and C23 Ampol D-C-Tron NR, respectively, were calculated using a 35 mm Petri dish. These values are higher than those previously recorded for M. persicae using a large 70 mm Petri dish which restricted air flow and reduced deposit.
