  • Myclobutanil is a triazole  chemical used as a fungicide. It is a steroid demethylation inhibitor, specifically inhibiting  ergosterol biosynthesis.
  • Ergosterol is a critical component of fungal cell membranes.
  • Myclobutanil is a systemic fungicide for the control of Apple Scab, Pear Scab and Powdery Mildew in Apples and Pears.
  • American Gooseberry Mildew in Blackcurrants and Gooseberries.
  • Powdery Mildew in Strawberries and Powdery Mildew, Black spot and Rust on Outdoor Ornamental Plants.
  • Myclobutanil is packaged in water soluble bags offering convenience of use, reduction of mixer/loader exposure, and elimination of container disposal problems.
  • Myclobutanil was reviewed in 1992 at the Joint Meeting on Pesticide Residues* for the purpose of establishing international maximum residue limits.
  • Myclobutanil has low acute oral, dermal and inhalation toxicity in rats and/or rabbits.
  • Myclobutanil is not expected to pose a direct hazard to wildlife.
  • However, its potential for persistence and mobility has raised questions about the possible off-target effects.
  • To minimize the risk of any significant off-target effect, the label was modified to include a 15-meter buffer zone between the last spray and aquatic habitats.
  • Myclobutanil can be applied
    up to 96 hours after infection providing growers with additional time in case of
    windy or wet weather, equipment breakdown, etc.
  • With this fungicide, a grower
    can delay the application of his first spray and extend the interval between sprays, thus reducing the number of pesticide applications.
  • Myclobutanil is also used at low-use rates (136 g ai/ha) thereby reducing the pesticide load in the orchard and minimizing any adverse effects on the beneficial predators and parasites.
  • Myclobutanil fits into Integrated Pest Management programs because of the low
    rate of active ingredient, fewer applications required, and its safety to beneficial predators, parasites and honey bees.
