Powdery mildew control of grapes with fungicides. Location: Mount Barker Research Station. Black spot and downy mildew of processing peas - 80AL32. Facial eczema investigation. Facial eczema is a recognised myco-toxic disease of grazing stock in New Zealand. It is caused by a fungus Pithomyces chartarum growing on dead litter part of the pasture. The disease has become recognised as a risk to sheep in the Albany Region following reported losses in 1978. A pasture paddock at Cape Riche was sampled weekly by the Animal Division to determine fluctuations in spore numbers of P. chartarum. Comments: The fungus could readily be found sporulating in abundance on fresh dried-off grass while on old only occasionally and then sparsely, and not at all on clover. In later work it was also found on aged clover runners. Work is planned to continue to find toxic strains of P. chartarum in this region.
