Soil or Vermiculite-Applied Microencapsulated Peppermint Oil Effects on White Mustard Initial Growth and Performance.

ABSTRACT: Microencapsulated peppermint (Mentha x piperita L.) essential oil (MPEO) is a prospective botanical herbicide. A hypothesis was formulated, that the type of growth medium (vermiculite or silty clay loam soil substrate) affects the phytotoxic potential of MPEO. A pot experiment in a randomized design assessed the effect of five doses of MPEO in a range of 0-108 g m-2 or 0-145 g m-2, mixed with vermiculite or with soil, respectively, on early growth of white mustard (Sinapis alba L. cv. Zlata), tested here as a model "weed" species. The morphologic analyses were supported by selected biochemical measurements. The two highest doses of microcapsules (from 73 to 145 g m-2) caused a significant decrease of plants' height and biomass. An increase of anthocyanin content in the aboveground parts of
