Tebuconazole is a systemic fungicide with protective, curative, and eradicant action. Rapidly absorbed into the vegetative parts of the plant, with translocation principally acropetally.
Used as a seed dressing, tebuconazole is effective against various smut and bunt diseases of cereals such as Tilletia spp., Ustilago spp., and Urocystis spp., also against Septoria nodorum (seed-borne), and Sphacelotheca reiliana in maize. As a spray, tebuconazole controls numerous pathogens in various crops: rust species (Puccinia spp.), powdery mildew (Erysiphe graminis), Rhynchosporium secalis, Septoria spp., Pyrenophora spp., Cochliobolus sativus and Fusarium spp. in cereals; Mycosphaerella spp., Puccinia spp. and sclerotium rolfsii in peanuts; Mycosphaerella spp. in bananas; Sclerotinia sclerotiorum and various pathogens of leaf and stem diseases in oilseed rape; Exobasidium vexans in tea; Phakopsora pachyrhizi in soya beans; Monilinia spp., rust species, powdery mildew and scab in pome and stone fruit; Botrytis spp., rust species, powdery mildew fungi, and (with dipping or spraying ) Sclerotium cepivorum in grapes and some vegetable crops.
