Facial Eczema Warning for Farmers
Facial eczema spore counts are at high levels throughout most of the North Island. AsureQuality is warning farmers that
the risk of facial eczema is high in many regions of the North Island following the prolonged drought and the recent
rain which has fallen on very warm soils.
The most recent report from Gribbles Veterinary Laboratory (17th of April) showed counts are at extremely high levels in
many districts.
Leo Cooney, Facial Eczema Monitoring Co-ordinator for AsureQuality says that, “The fungus Pithomyces chartarum (that produces the toxic spores), thrives on drought desiccated pastures where the surface soil temperatures remain
warm following a soaking of rain.”
He says that, “This results in the desiccated litter at the base of the pastures decaying rapidly and providing an ideal
medium for the fungi to use as a nutrient, and in turn produce its very toxic spores.”
Although night and morning temperatures may feel cooler, it takes a lot to cool the earth’s soil temps down at this time
of the year. Soil temps taken in the Horowhenua last week ranged between 19.3 and 21.5 C, perfect growing conditions for
the toxic spores.
Farmers need to remain vigilant and keep precautions fully in place until facial eczema spore counts and soil
temperatures drop. Historically our worst outbreaks of facial eczema have followed prolonged droughts, when susceptible
livestock are grazing very short pastures.
