Abstract: |
In this study, Basudin 60 EM,
Cupravit OB 21 and Dursban 4 of synthetic pesticides widely
used in agriculture, bordeaux mixture of natural pesticides
and Componion of biologic pesticides was investigated the
effect on the bacteria isolated from microbial flora. In
this context it was aimed to compare the effect of
pesticides used in conventional and organic farming on
microbial flora. The changes of metabolic activity was
demonstrated according tothe effects of pesticides in the
microbial flora. The leaf and soil samples obtained
elaborately from the same station, Bacillus cereus DY6,
Micrococcus yunnanensis DT1 and Bacillus tequilensis DT2
were selected as indicator strains. The changes in
antibiotic susceptibility and generation time as metabolic
activity of these microorganisms and genetic modifications
that creates on indicator strain were investigated. As a
result, it was determined that pesticides used in
applications of organic farming changed metabolic activities
of the bacteriaas much as conventional applications. It has
been found that especially bordeaux mixture as a natural
pesticide used in Turkey causes genetic modifications. |
