Abstract
The objective of the study was to evaluate the efficacy of foliar insecticide spray applications for control of worm pests (BAW and CL) and SWF on iceberg head lettuce under desert growing conditions. Head lettuce (Keeper, M.I.) was direct seeded on 18 Sep 2013 at the University of California Desert Research and Extension Center, El Centro, CA into double row beds on 40 inch centers. Stand establishment was achieved using overhead sprinkler irrigation, and irrigated via furrow irrigation thereafter. Plots were four 40 inch beds (13.3 ft) wide by 50 ft long with one non-planted bed between plots and 5 ft between blocks. Four replications of each treatment were arranged in a RCB design. Insecticidal compounds, formulations and application rates are provided in the tables. All insecticide treatments were foliar sprays applied with a Lee Spider Spray Trac Tractor, 4-row sprayer with three TJ-6
