To go further: OPTIDOSE
- L? IFV offers an online computer module that presents winemakers with approved dose reductions to request treatments according to three criteria:?The average phenological stage at the time of treatment; ?the volume of the foliar seto (calculated from a dozen measurements made at different points of the plot: height of the foliage to be protected.
- Width of foliage and distance between rows); parasitic pressure.
This technique was tested in 2016 Tauxières.La a 15% reduction in anti-mildiou compared to the operating reference programme had no significant consequences. In fact, at the beginning of the winter, foliar attack intensities were 2.1% in Optidose mode compared to 1.9% in clusters, crop loss was 3.5% and 3%, respectively.
