Tebuconazole is a broad-spectrum azole which is also effective against the fungus Botrytis cinerea. Tebuconazole does not reduce the rate at which the fungus produces spores, but it has clear-cut effects on the growth of the germ tube and mycelium. Tebuconazole exhibits good effects in vivo after inoculation with spores and after inoculation with spores as well mycelium. Tebuconazole is effective against all strains of Botrytis which infect vines. The good results in laboratory and glasshouse trials have been confirmed by many field trials with post-blossom spraying against Botrytis cinerea. To enhance the effectiveness, to broaden the spectrum of action and to prevent the emergence of resistance, in the field trials tebuconazole was usually combined with dichlofluanid or procymidone. The results were very good. Compatibility with different varieties, yields, fermentation properties and the taste of the wine were good after use of tebuconazole alone and in combination with dichlofluanid or procymidone. Tebuconazole, a new fungicide, extends the range of treatments available for controlling Botrytis in vines
Steroid demethylation (ergosterol biosynthesis) inhibitor.
Mode of action
Systemic fungicide with protective, curative, and eradicant action. Rapidly absorbed into the vegetative parts of the plant, with translocation principally acropetally.
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), at 1-3 g/dt seed; and Sphacelotheca reiliana in maize, at 7.5 g/dt seed. As a spray, tebuconazole controls numerous pathogens in various crops including: rust species (Puccinia spp.) at 125-250 g/ha, powdery mildew (Erysiphe graminis) at 200-250 g/ha, scald (Rhynchosporium secalis) at 200-312 g/ha, Septoria spp. at 200-250 g/ha, Pyrenophora spp. at 200-312 g/ha, Cochliobolus sativus at 150-200 g/ha, and head scab (Fusarium spp.) at 188-250 g/ha, in cereals; leaf spots (Mycosphaerella spp.) at 125-250 g/ha, leaf rust (Puccinia arachidis) at 125 g/ha, and Sclerotium rolfsii at 200-250 g/ha, in peanuts; black leaf streak (Mycosphaerella fijiensis) at 100 g/ha, in bananas; stem rot (Sclerotinia sclerotiorum) at 250-375 g/ha, Alternaria spp. at 150-250 g/ha, stem canker (Leptosphaeria maculans) at 250 g/ha, and Pyrenopeziza brassicae at 125-250 g/ha, in oilseed rape; blister blight (Exobasidium vexans) at 25 g/ha, in tea; Phakopsora pachyrhizi at 100-150 g/ha, in soya beans; Monilinia spp. at 12.5-18.8 g/100 l, powdery mildew (Podosphaera leucotricha) at 10.0-12.5 g/100 l, Sphaerotheca pannosa at 12.5-18.8 g/100 l, scab (Venturia spp.) at 7.5-10.0 g/100 l, white rot in apples (Botryosphaeria dothidea) at 25 g/100 l, in pome and stone fruit; powdery mildew (Uncinula necator) at 100 g/ha, in grapevines; rust (Hemileia vastatrix) at 125-250 g/ha, berry spot disease (Cercospora coffeicola) at 188-250 g/ha, and American leaf disease (Mycena citricolor) at 125-188 g/ha, in coffee; white rot (Sclerotium cepivorum) at 250-375 g/ha, and purple blotch (Alternaria porri) at 125-250 g/ha, in bulb vegetables; leaf spot (Phaeoisariopsis griseola) at 250 g/ha, in beans; early blight (Alternaria solani) at 150-200 g/ha, in tomatoes and potatoes. Phytotoxicity Good plant compatibility in most crops with any formulation, and achieved in more sensitive crops by appropriate formulations, e.g. WP, WG or SC.
