Bazı Pestisitler ve Odun Sirkesinin Buğday Agro-Ekosistemindeki Toprak Nematodlarına Etkileri

Abstract

In this study, the effects of some pesticides and wood vinegar on freeliving nematode trophic groups common in soil were investigated in a wheat field. Field experiments were conducted in 2014-2015 and 2015-2016 growing seasons in a winter wheat field with a randomized block design with four replicates in Muş Province, Turkey. The treatments were consisted of; 1) pesticide application (i.e., chemicals used for all wheat diseases, weeds and pests in the region), 2) 0.5, 1, 2, 3, 4 and 5% ml wood vinegar, which equates to pesticide application, and 3) untreated control In the field, 19 genera and one order of nematodes were found from five nematode trophic groups. In 2014In -2015In and 2015In -2016, the number of predator nematodes were 25 and 136, and the number of the most common plant parasitic nematodes were 3012 and 3657, respectively. From first to second growing season, the number of omnivore nematodes decreased, whereas other nematode groups increased. According to a simple correspondence analysis, it was determined that generally, there were significant connections between the treatments, and the measured properties and nematode trophic groups.
