| Flavescence dorée and the mandatory control of its vector Scaphoideus titanus pose important problems in organic vineyards. The goal of our field studies conducted in the Ticino was to develop a pest control strategy conform to the guidelines of organic production. Insecticides containing pyrethrin were the only organic products showing an efficacy higher than 90% against the immature stages of S. titanus. However, these products had no effect on adult leafhoppers. Repeated applications of pyrethrin proved to be toxic against the predatory mite species Amblyseius andersoni.
