Field and greenhouse application of an attract‐and‐kill formulation based on the yeast <i>Hanseniaspora uvarum</i> and the insecticide spinosad to control <i>Drosophila suzukii</i> in grapes

Abstract

In comparison to typical spinosad spray applications, the use of H. uvarum in combination with spinosad as an attract-and-kill formulation against D. suzukii reduces pesticide residues on the fruits by targeting the treatment to the canopy and decreasing the amount of insecticide per hectare without compromising control efficacy.
