Efficacy of agrochemicals against Phyllobius oblongus

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.
