Abstract
About 75% of the conidia of Nomuraea rileyi (Farlow) Samson layered on a 10.5 cm-column of sand were recovered in the filtrate after exposure to the equivalent of 16.25 cm of rain. In contrast, no conidia were recovered in filtrate from a silt-loam soil, and over 90% of the recovered conidia were in the upper 2 cm of the column. Conidia probably are held in the surface of loam soil by adsorption on clay or organic particles. Number of conidia was determined by use of a hemocytometer and phase microscopy; activity was determined by using a Trichoplusia ni (Hübner) bioassay.This publication has 4 references indexed in Scilit:
