Abstract: The contact, residual, and ingestion efficacy of two conventional insecticides was compared with that of another five environmentally friendly agrochemicals in a laboratory for the control of the European snout beetle. Very good efficacy was observed for the conventional product Reldan 22® after all types of exposures. The conventional Mospilan® 20 SP showed good efficacy after ingestion. SpinTor® was very effective 72 h after ingestion and contact, and Siltac® EC showed comparable efficacy with conventional insecticides 72 h after ingestion and residual contact. SpinTor® and Siltac® conform to the principles of organic farming and integrated pest management (IPM) and are able to replace both the tested conventional products in young fruit plantations and nurseries. Pyrethrum PNC - 17, FerrumOil, and Boundary SW did not sufficiently control the beetle.
