Breitsäscharen: Ablagetiefe und -qualität optimieren

Delaying the timing of the first hedge trimming is of limited technical value in vineyard canopy management. Its impact on lateral shoot growth and must composition is minimal.

Plant protection products contain active substances and co-formulants. Agroscope studied the residues of co-formulants on treated plants for the first time, thereby furnishing the basis for assessing risks posed to consumers.

The effectiveness of an application of foliar nitrogen at veraison depends on the initial level of vine nitrogen deficiency, an Agroscope study has shown. The threshold levels of assimilable nitrogen deficiency in the grape must are validated for Chardonnay but still need to be confirmed for Sauvignon Blanc.
