Summary: This trial was designed to evaluate reduced risk insecticides as possible replacements for the grower standard insecticides. This trial was conducted on ‘Granny Smith’ apple trees in a commercial orchard near Hollister, CA. Nineteen treatments were replicated four times in a RCB design. Each replicate was a group of two to four trees. The trees were about 12 ft tall. Treatments were applied with a handgun orchard sprayer operating at 200 psi and delivering a finished spray volume of 150 gpa (5 gal/replicate). Application timings were based on DD. DD were calculated with a biofix of 1 Apr for the first generation of CM and a biofix of 26 Jun for the second generation using a single sine horizontal cutoff model with a lower threshold of 50°F and an upper threshold of 88°F. Maximum and minimum air temperatures were obtained from the HOLLISTR. A (CIMIS #126) weather station in San Benito, CA. Flight activity of male CM was monitored weekly from 18 Mar through 24 Aug with a Suterra 1X Patch and a Trécé DA Combo lure in Trécé 1CP traps placed high in the canopy of two trees and was used to determine biofix. Control of CM was evaluated at the end of the 1st generation on 24 Jun by inspecting 125 fruit per replicate on the tree. CM infestation damage was evaluated on 25 Aug at commercial harvest by removing 250 fruit per replicate and inspecting them in the laboratory. CM stings and strikes as well as total infestation were recorded for the harvest evaluation while only total infestation was determined for the first generation evaluation. Data were analyzed using ANOVA and means were separated using Fisher’s protected LSD (P ≤ 0.05).
