Monitoring of bio aerosols over groundnut fields was undertaken for two consecutive Kharif crop seasons during the years 2012 and 2013 at Newasa, Dist. Ahmednagar (M.S.), to study a definite correlation between the air borne micro organisms, meteorological parameters, growth stages of the crop plants and their impact in bringing about the disease incidence to the ground nut crop plants. A volumetric Tilak Air Sampler was used to trap airborne biological components, which incidentally provided continuous quantitative and qualitative data. Present investigation also mainly aimed to study the population of fungal morphotypes prevailing in the ambient air over the ground nut fields in two Kharif Crop seasons. Prevailing weather conditions during two Kharif seasons showed significant influence on the genesis and liberation of spores of fungal morhotypes and eventually affected the total composition of airspora quantitatively and qualitatively. During the period of present study, many already known allergenic pollen and fungal spores were recorded and have been estimated for their percentage contribution.
