  • Rust has been noticeable in many pastures over the last few weeks. It is an airborne fungus that occurs during hot and humid weather. Spores attach themselves to less healthy parts of the plant, usually the dead or dying leaves in the base of the pasture. You will not see rust on new emerging tillers, plants within a urine patch or on clover. Pastures that have been managed well for quality with optimal residuals will see less rust than laxly grazed pastures.

    Rust is harmless to stock but it reduces the palatability of the pasture, reducing intakes.

    Scott Farm sampled and tested five paddocks for facial eczema on Friday 22 January. Two paddocks had no spores while the other three paddocks ranged from 5-15,000 spores per gram.

    We have seen a wide range in spore counts across the Waikato in recent weeks along with some clinical cases.  Preventative measures for facial eczema should be in place now. Check spore counts for your local district with your vet practice.
