A volumetric spore trap for sampling pastures

摘要

When it was established that the fungusSporidesmium bakeriSyd. can cause the disease of sheep known as facial eczema (Thornton and Percival 1959), the need arose for a method of estimating the amount of this fungus in a pasture. The rapid sporulation ofS. bakeriand the case with which the conidia are detached suggested that assessment of spore numbers should give a fair measure of the abundance of the fungus.
