The objective of the study was to evaluate the efficacy of insecticides for control of aphids on cauliflower under desert growing conditions. Cauliflower “Cumberland” plants were transplanted into single row beds on 40-inch centers on 1 November 2013 at the University of California Desert Research and Extension Center, El Centro, CA.
