Processed Kaolin as an alternative insecticide against the European pear sucker, Cacopsylla pyri (L.)ClaudiaDanielauthorWPfammatterauthorPKehrliauthorEricWyssauthorApplication of processed kaolin particle film repels insects without lethal effects; hence side effects on beneficial arthropods are low. Processed kaolin may be an alternative to broad-spectrum insecticides used against European pear sucker, Cacopsylla pyri (L.), in organic and conventional pear production. Trials showed that the processed kaolin showed a very high efficacy, and the population of C. pyri was kept under a damaging level over the whole season. In conclusion, kaolin shows promise as an alternative control for C. pyri in organic and orchards of Integreted Pest Management. Crop health, quality, protection2005Journal paper
