Vinetur reports that a peer-reviewed study of 313 non-organic Swiss winegrowing farms found a striking divide in approaches to pesticide reduction, with 52% classified as relatively low users of integrated pest-management measures and 48% adopting a much broader range of alternatives. Researchers examined 21 practices, including disease forecasting, mechanical weed control, pheromones, beneficial insects, resistant grape varieties and precision spraying technology. Growers with higher adoption rates tended to operate larger farms, market wine themselves and make greater use of agricultural advice and information, leading the researchers to argue that policies encouraging combinations of measures, rather than individual techniques in isolation, may be more effective.
