Circadian periodicity study of some important fungal spores over Jowar crop field at Jamkhed,Dist.Ahemednagar.

S.M. Baraskar


Circadian periodicity study of some important fungal spores over jowar crop such as Aletrnaria, Cercopsora and Cladosporium were described from data obtained by sampling air with the help of continuous volumetric “Tilak air sampler” duringtwo Kharif seasons from 15th June 2009 to 20th October 2009 and 15th June 2011 to 24th October 2011.  The sampling was carried out over Jowar(Sorghum vulgare.Pers)  crop field at Jamkhed Dist. Ahmednagar. The Circadian periodicity of Aletrnaria, Cercopsora and Cladosporiumwere mentioned with respect to the related weather parameters and it confirmed that these spore types shows day pattern.Maximum incidence ofCercopsoraspores was observed in the month of September whereas Aletrnaria and Cladosporiumspore types were observed in month of August respectively.
