Kaolin is authorized in Swiss vineyards to control the Spotted-wing drosophila (Drosophila suzukii). Its efficacy against D. suzukii was demonstrated in 2016 in 26 field trials where kaolin achieved an average efficacy of 54%. Although the International Oenological Codex accepts it as a fining agent, kaolin contains aluminum (Al), which raises concerns about its presence in the food chain and its risks to human health. In order to study the influence of repeated applications of kaolin during grape ripening on the aluminum content of wines, a field experiment was set up in 2015 at the Agroscope site of Changins. Three applications of kaolin (Surround WP®) at 12 and 24 kg·ha-1 were realized on the red grape variety Mara shortly before harvest (worst-case scenario). Bottled wines, tasted in 2016, could not be distinguished from an oenological and gustatory point of view from the untreated control. The aluminum analysis of wines carried out in 2018 showed a dose response of kaolin applications. However, the levels observed remained well below the maximum recommended level for this metal (8 mg·L-1) with average values of 0.083, 0.184 and 0.211 mg·L-1 for the control, 3 x 12 kg·ha-1 and 3 x 24 kg·ha-1 kaolin, respectively. We therefore conclude that kaolin applications are effective against D. suzukii and do not cause any major risks to the environment, to the wine quality and to human health.
