The thesis is focused on the evaluation of the behavior of herbicides in the growth of kohlrabi. The theoretical and general information on pesticides and herbicides on their behavior in the soil, phytotoxicity (plant injury) and vegetables, are presented in the beginning of the thesis.
A central part deals with the differences in behavior of herbicides in soil with active ingredients metazachlor and pendimethalin, their interaction when applied in a combination and how they behave in the soil when applied separately. It also deals with the results of half-life of applied herbicides. Whether among them was a significant difference in the use of adjuvants, and what kind of effect have the irrigation influenced the experiment. It also evaluates the effect of active substances on the expression of phytotoxicity kohlrabi.
The closing part is focused on the statistical evaluation of the particular options of the applied herbicides. Based on the results the hypothesis has been confirmed. The behavior of the active substances in the soil, which have been applied in the form of mixtures, was differed from the applied herbicides separately. It was found that the applied substance in the mixture have a greater effect on weed control in the crop kohlrabi , longer half-life and their effect on the crop plants is manifested phytotoxic.
The significant impact on the overall evaluation has have the irrigation, which should be an integral part of the application process herbicidal compositions and a follow-up care of a vegetation.
