Publisher's Synopsis
Excerpt from Evaluation of Polybutenes as Miticides
Resistance of mites to many miticides has become a matter of major concern. The problem of controlling phytophagous species in Canada by che 'cal means and the need for a new approach to control were cited by Fisher (ll in his initial report on the polybutenes. The United States has similar problems and needs in controlling mites on deciduous fruit trees, especially apple. This report gives the results of biological and chemical studies of the use of polybutenes for controlling mites on apples, which were undertaken after exploratory field studies conducted in 1959 showed that these materials had a deterrent effect on the development of mite populations. This effect is due to their nondrying, highly viscous characteristics. The mites are trapped mechanically and prevented from feeding and reproducing.
