Abstract
Fusarium head blight of wheat causes significant reductions in yield, test weight, and seed quality and may be associated with mycotoxin contamination of grain. The objective of this study was to evaluate certain fungicides for effects of head blight severity, deoxynivalenol level, yield, and test weight under conditions of high disease pressure in the field. Fungicides (benomyl, chlorothalonil, fenbuconazole, flusilazole, myclobutanil, potassium bicarbonate, propiconazole, tebuconazole, thiabendazole, and triadimefon plus mancozeb) were applied to wheat cv. Florida 302 at heading stage in 1992 and 1993. Plots were inoculated three times with macroconidia of Fusarium graminearum and misted to promote severe head blight epidemics [...]
