HEC5725:: A novel leaf-systemic strobilurin fungicide

HEC5725 is a leaf-systemic broad-spectrum fungicide from the chemical class of dihydro-dioxazines currently being developed for use mainly in cereal crops. The compound provides both a rapid initial effect and prolonged activity due to its protective and leaf systemic properties. Applied as a foliar spray in cereals, HEC5725 provides excellent control of Septoria leaf spot (Septoria tritici), Septoria leaf and glume blotch (Leptosphaeria nodorum), rust (Puccinia recondita, P. striiformis, P. hordei), Helminthosporium diseases in wheat and barley (Pyrenophora tritici-repentis, Pyrenophora teres) as well as scald (Rhynchosporium secalis) and powdery mildew (Blumeria graminis spp.). Furthermore, seed and soil-borne diseases like snow mould (Monographella nivalis) and common bunt (Tilletia caries) are also efficiently controlled, when BEC5725 is used as a seed treatment. Mixtures of HEC5725 with selected fungicides often result in an increased biological activity against these diseases. BEC5725 has a favourable regulatory profile.
