Control of Mites on Citrus with Chlorobenzilate1

The citrus bud mite, Aceria sheldoni (Ewing), is one of the most serious pests of lemons in the coastal areas of California. In 1941, Boyce & Korsmeier found that petroleum oil sprays were effective in control of this mite pest, and since that time these sprays have been largely relied on for control. In citrus culture, however, there are many situations in which it is inadvisable to apply petroleum oil sprays. Therefore, studies directed toward findng a substitute chemical control have been in progress at this station for several years.
