<p>¹ Tav, Tmin, Tmax = average, min, and max daily temperature; RHav, RHmin, RHmax = average, min, and max daily relative humidity; WDt = total wetness duration; RH90 = hours with RH > 90%; VPD = vapor pressure deficit; Rt = total rain.</p><p>² 0 = days with no ascospore discharge or no ascospore peaks; 1 = days with ascospore discharge or ascospore peak.</p><p>³ Ascospores were sampled with a volumetric spore sampler from the air above maize stalk residues bearing mature <i>F</i>. <i>graminearum</i> perithecia.</p><p>⁴ Peaks are defined as days with ≥ 30 ascospores / m³ air.</p><p>⁵ Probability level of the <i>t</i>-test for differences between the two ascospore groups (0 = no, 1 = yes).</p><p>⁶ Probability level of the <i>t</i>-test of differences between presence and peak of ascospores.</p><p>Weather data during periods with and without discharge of <i>Fusarium graminearum</i> ascospores, and with and without peaks of discharge, in North Italy in 2012 to 2014.
