Daniel, Claudia and Wyss, Eric (2004) Efficacy of different insecticides and a repellent against the European pear sucker (Cacopsylla pyri). [Wirkung verschiedener Insektizide und Repellentien gegen den Gemeinen Birnenblattsauger (Cacopsylla pyri).] In: Boos, Markus (Ed.) Ecofruit - 11th International Conference on Cultivation Technique and Phytopathological Problems in Organic Fruit-Growing: Proceedings to the Conference from 3rd February to 5th February 2004 at Weinsberg/Germany, pp. 35-40.
The efficacy of different insecticides (neem, pyrethrin, spinosad, and rotenone) and a repellent (kaolin)
applied with different strategies (single or repeated applications) against the over-wintering pear
suckers (Cacopsylla pyri) and nymphs of the first generation was tested in a field trial in Switzerland
in spring 2003.
Rotenone, the only admitted product in Swiss organic agriculture, showed good effects. But, since
Rotenone is toxic for non-target insects we looked for an alternative. The application of spinosad
(Audienz) in combination with rape oil (Telmion) as well as the application of pyrethrum showed
similar efficacy as rotenone. Neem had no or a very low impact on the pear sucker populations. The
repellent kaolin (Surround® WP) showed the best efficacy against the European pear sucker: triple
application of kaolin before blossom was most efficient. Since kaolin is not toxic for beneficials this
product might be an alternative to rotenone.
