FUNGICIDES EFFECT ON SOIL MICRO FLORA IN TEKKALI MANDAL, SRIKAKULAM (DIST.)
Keywords:
Soil fungi, effects of fungicides, common fungicides.Abstract
In this study was examined the response of microbial populations in soil after the application of several fungicides. The soil samples were collected from experimental plots field at village tekkali in and around the circumstance, localized at 20 kilometres, on January 2015-November 2015. The soil was collected from upper 10 cm of the soil profile. In the laboratory plant material and soil macro fauna were removed and the soil samples were sieved (<2mm) and mixed. Each soil sample was treated with one of the following fungicides at recommended dosages: Copper Oxy Chloride (COC) at the rate of 0,0025g/, Carbendzim at the rate of 0,01g/ and Cmmodity Mancozeb at the rate of 0,01 ml. Controls, consisting of soil only, were included within all tests. The numbers of total microorganisms were determined using the dilution method. By these fungicides effect on total viable fungi were investigated in laboratory experiments, these results compared with my previous studies, fungal colonies were dropped, graphically and statistically analyzed.
