Aeromycoflora studies above an “Aman” variety of paddy (Oryza salivaL.) were carried out for two consecutive seasons, in 1990 and 1991, in the vicinity of Barrackpore, West Bengal, by means of the culture plate exposure technique. A more or less uniform spore concentration was observed during the early part of the vegetative stages in 1990 with an abrupt increase and peak during the maximum vegetative growth period. In 1991, a uniform spore count was found up until the flowering stages. A gradual increase in spore count after flowering was recorded in both seasons with the highest peaks during harvesting, followed by a sudden decrease after the harvest. The dominant genera isolated wereAspergillus, Currularia, CladosporiumandPenicillium. Aspergillusappeared in high concentrations from the very beginning of the crop season up to the flowering stages, with a gradual fall after flowering, whileCladosporiumshowed the reverse pattern.CurrulariaandPenicilliumoccurred regularly throughout the crop season.
