Two of the newer chemicals show outstanding possibilities for the commercial grower's use to control mites injurious to citrus in California. The materials are specific acaricides—mite-killers—and therefore they are relatively nontoxic to beneficial insects, so treatments result in a minimal effect on insect parasites and predators as well as bees. Nor does their application effectively reduce populations of injurious insects.
