There are many researches on the role of pesticides used in agricultural applications in the ecosystem. However, detailed research on microbial flora, especially for metabolic activity products, has not been found. Therefore, in our study the effect on microbial flora of natural pesticide, bordeux mixture used in the control of plant harmful and diseases in agricultural applications was evaluated in terms of production of EPS and siderophore. By now, looking at the studies on the effects of pesticides on the microbial flora, it was seen that they are generally evaluated in terms of bacterial inhibition, but studies on the effects of these substances on microbial metabolism have been found to be incomplete. According to the data obtained from this study, it was determined that the bordeux mixture application on the isolated strains from agricultural lands reduced EPS production efficiency ( in Bacillus cereus DY6 and - in Bacillus tequilensis DT2) and increased siderophore production. As it is known, while synthetic pesticides have a destructive effect on microbial flora, due to the stress conditions it creates, natural pesticide applications can also make a high rate of change in the bacterial useful metabolic products for agriculture. | Effect of natural pesticide Bordeux mixture on the production of metabolite (EPS and Siderophore) in some PGPBs
