Abstract
By sampling air with rotorods at different heights above ground level and at different times of the day it was possible to characterise the diurnally changing abundance of fungal spores and also the vertical profiles of changing concentrations within and above a crop of rice at Bhimavaram, Andhra Pradesh.
The spores of some fungi, notablyNigrospora, Myrothecium andCladosporium were more abundant between 0800 and 1100 h than at other times of the day. In contrast maximal concentrations ofLeptosphaeria spores were detected between 2400 and 0300 h. Idealised theoretical profiles showing logarithmic decreases in spore concentrations with increasing height were always obtained when considering total spora but for individual spore types they were only obtained during their periods of maximum atmospheric concentrations. Unlike the profiles of other fungi those of the false smut fungusUstilaginoidea virens tended to show increasing concentrations both above and below crop level.
