ABSTRACT
Modern high-performance crop farming is impossible without fungicides. A most promising way to enhance agricultural production and improve its quality is to protect crops against diseases and pests. New fungicide formulations need to be developed to increase the efficacy of fungicides and minimize their harmful effects on the environment. The most common commercial tebuconazole (TEB) formulations are suspensions or emulsions, which are used to spray the vegetative organs of plants. Standard formulations are present at higher concentrations than required for activity at the time of application in order to guarantee the duration of effect at later time intervals. TEB formulations were buried in the soil. A possible explanation for this is that the concentration of TEB added to the soil as the active ingredient of the commercial formulation was initially much higher than the concentration of TEB released from the experimental formulations.
