Abstract
Fusaria spore populations on herbage from grazed ryegrass-dominant pastures were determined. Spore loads were markedly higher on herbage from urine patches than on herbage from inter-excreta sites. Within urine patches there was a higher spore load on dead material resulting from urine scorch than on other dead material within the growth-response zone. Profile and component sampling indicated that Fusaria spore distribution patterns were similar to those previously found for spores of Pithomyces chartarum (Berk. & Curt.). M. B. Ellis.
