Aerobiology and Correlation of Field Disease Incidence in Rust on Groundnut Crop

摘要

Air sampling was done over groundnut crop at Patan. The aim of the air monitoring was to find out the concentration of pathogenic rust spores, their relation with meteorological parameters and growth stage of crop. Air sampling was done in two consecutive Kkarifand Rabiseasons. Air monitoring revealed the maximum concentration of leaf spots of rust (Puccinia arachidis) spores in the month of October in Both A^an/seasons and in month of February in both Rabi seasons. The incidence of pathogen and seventy of infection were correlated with meteorological data of respective season.
