EVALUATION OF MOVENTO 240SC FOR CONTROL OF SAN JOSE SCALE, 2010

Several programs of insecticides were applied at various timings through out the 2010 growing season to evaluate the effectiveness of Movento 240SC against San Jose Scale (SJS). Treatments were arranged in a RCB design and replicated four times in 4-tree blocks within a research orchard consisting of MacIntosh and Cortland planted at 20 ft spacings and 40 ft row spacing. These plots were sprayed at 150 gpa using a conventional air-blast sprayer manufactured by Durand Wayland Co. A full list of treatments including materials used and application timings and rates is listed in Table 1. Fruit was evaluated on the tree for 1 gen SJS damage on 23 Jun, 4 Aug for the 2 gen and final harvest readings were taken on 27 Aug by picking and inspecting the fruit. One hundred fruit/plot were sampled in each replication. Data was transformed and subjected to an ANOVA. Means were separated with Fisher’s Protected LSD Test (P<0.05).
