Abstract :Chemical drugs insert ignore into journalissuearticles values(pesticides); that are xenobiotic to the nature of agricultural agro-ecosystems affect the target organism and non-target factors. The efficiency and reliability of agricultural areas are important not only for living creatures in the environment but also for the community. This study was carried out to determine the effects of Demond EC 2.5 insert ignore into journalissuearticles values(insecticide);, Granland DF insert ignore into journalissuearticles values(herbicide); and Safacol 70 WP insert ignore into journalissuearticles values(fungicide); pesticides, which are widely used in the agricultural areas of Muş, on the development of non-target wheat plant, free-living nematodes, microfungi, and aerobic mesophilic bacteria communities. The study was performed in three replicates in the variance analysis method for repeated measurements in laboratory conditions. Pesticides were applied by spraying to the pots including one kg of soil as recommended and upper doses, respectively, with the help of an injector. Repeated Measurement ANOVA and Profile Analysis Technique were used in the comparison of treatments in terms of nematode, bacteria and microfungi numbers insert ignore into journalissuearticles values(before-after);, and the Analysis of Means insert ignore into journalissuearticles values(ANOM); Technique in comparing treatments in terms of plant parameters. As a result of the experiments; While the effect of only periods is important for the bacteria combination insert ignore into journalissuearticles values(P=0.001);; for the microfungi community, both periods insert ignore into journalissuearticles values(P=0.004); and Period × Treatment interaction were found significant insert ignore into journalissuearticles values(P=0.050);. Periodic × Treatment interaction was statistically significant for plant-parasitic, omnivore-predator, bacterivore and total nematodes respectively insert ignore into journalissuearticles values(P=0.002; P=0.004; P=0.001; P=0.000);. As a result; the pesticides used had more or less positive effects on the microfungi community, while they had a negative effect on the bacteria community; According to trophic levels, soil nematodes and plant parameters were found to have a positive/negative effect. It is thought that pesticides should be used in the last resort and recommended dosage, without forgetting that the soil is complex and all living things share this environment.
