This study was made to determine the impact of pesticides and wood vinegar, used to protect plants in wheat agroecosystems, on the Alkaline phosphatase and Beta-glucosidase soil enzymes' activities, comparatively. The study was made at the end of the production seasons of 2014-2015 and 2015-2016, on a field of winter wheat field under the ecologic conditions of Mu province, with four repetitions and in a fixed way according to the Randomized Block Experiment Pattern. The plant protection product applications in the study were: It was conducted as a pesticide application and control application, in which not any plant protection product (pesticide and wood vinegar) was applied with the wood vinegar dosages of 0.5% - 1% - 2% - 3% - 4% and 5% mL; corresponding to the pesticide application. In 2015, as the average enzyme activity for Alkaline phosphatase, the lowest value (9.409) was in pesticide and highest (11.262) was in 1% mL wood vinegar, and for Beta-glucosidase, the lowest value (4.329) was in 5% mL wood vinegar and the highest (4.829) was in 0.5% mL wood vinegar. In 2015, about the feature of enzyme activity; the interactions of Dose x Time x Type (P=0.372), Time x Type (P=0.957), Dose x Time (P=0.470) and the exclusive impact of time (P=0.146), were not found to be statistically significant, and the interaction of Dose x Type was found to be statistically significant (P=0.016). In 2016, it was found that the enzyme activity was increased after the application compared to before, in general, and the interactions of Dose x Time x Type (P=0.208), Dose x Time (P=0.799) and Dose x Type (P=0.345) were not found to be significant. It was found that the conducted pesticide and wood vinegar applications at different doses had impacts on the activities of Alkaline phosphatase and Beta-glucosidase, of the soil enzymes. It was also found that the wood vinegar did not affect the activities of these enzymes negatively and it was even promising in increasing the enzyme activities in some applications.
