INVESTIGATION OF HELMINTHOSPORIUM SPORE CONCENTRATION AT UDGIR

Dr. Lohare Sunita Dhundiraj*

ABSTRACT

Aerobiology is the study of air borne microorganisms like fungal spores, insect part, pollen grains, protozoan cyst and other biological parts. By considering the importance of vegetables for human beings, the investigation deals with the airspora over Onion field at Udgir. Similarly investigation have been undertaken to concentrate more attention on disease incidence by air borne fungal pathogens in Onion (vegetable-perticularly onion, Tomato, Brinjal) field and divicing disease forecasting system. The present investigation deals with the study of microscopic air spora over the Onion (Allium cepa L.) (Vegetable) field at Udgir. This study was conducted for rabbi season from 1st November 2017 to 25th January 2018 using continuous Tilak air sampler. In the air sampling 56 airborne components trapped among these 01 belongs to Phycomycetes, 12 belongs to Ascomycetes, 03 belongs to Basidiomycetes, 34 to Deuteromycetes and 06 to other types. The highest percentage contribution of the spore belongs to Deuteromycetes group was 71.76%, Ascomycetes 16.36%, other types 7.85%, Basidiomycetes 3.32% and Phycomycetes 0.71%. In this study Cladosporium was most dominant type among the fungal spores contributed 21.89% to the total air spora and Helminthosporium contributed 4.42% to the total airspora and ranked third from Deuteromycetes group. The airspora studies over Onion fields have contributed to understand the general components of airspora in this region. It also revealed that the occurrence of spores in air correlate with weather condition. The present study will be useful in divicing for disease forecasting system of Onion crop which would help for protecting the crops from infection and disease.
