Air sampling over vegetable field was carried out by using continuous Tilak air sampler from 1st November 2016 to 30th January 2017 for Rabbi season. The main aim of this experiment is to find out the concentration of air borne Curvularia spores and their relation with the disease incidence. In the investigation Curvularia spore concentration was16578 spores/m3 of air recorded during the season from Aerobiological sampling the fluctuation in the concentration of Curvularia spores wear observed in different growth stages of the crop. Maximum concentration of Curvularia spores wear recorded 8242 spores/m3 of air in the month of December 2016.
