Abstract
The aim of the study was to determine the effect of soil-maltodextrin (MDX) and MDX microencapsulated essential oils (EOs, 12%) of peppermint (Mentha × piperita L.), caraway (Carum carvi L.) or calamus (Acorus calamus L.) at various doses (0.75, 1.5 and 3 g/pot), on the initial growth of maize (Zea mays L.), barnyard grass [Echinochloa crus-galli (L.) P. Beauv.] and lambsquarters (Chenopodium album L.). The results of a pot experiment showed the strongest inhibitory effect on the growth of the studied plants of MDX alone. Both the MDX and microencapsulated EOs decreased the relative chlorophyll content of the leaves in maize. Maize was the most tolerant to the microencapsulated EOs while lambsquarters was more sensitive to the microcapsules compared to barnyard grass. The highest doses of microencapsulated EOs, particularly those containing peppermint or caraway, caused the greatest decrease in the number and dry weight of the weeds. Based on the results, it can be concluded that the microencapsulated EOs pose a phytotoxic effect against weeds and should be studied further under field conditions. Celem badań było określenie wpływu mikrokapsułkowanych w maltodekstrynie olejków eterycznych z mięty (Mentha × piperita L.), kminku (Carum carvi L.) i tataraku (Acorus calamus L.) oraz samej maltodekstryny na początkowy wzrost kukurydzy (Zea mays L.), chwastnicy jednostronnej [Echinochloa crus-galli (L.) P. Beauv.] i komosy białej (Chenopodium album L.). Preparaty dodawano w różnych dawkach do gleby. W efekcie doświadczenia wazonowego stwierdzono, że wszystkie preparaty wywoływały silny efekt hamujący początkowy wzrost badanych roślin, a najsilniej działała maltodekstyna bez dodatku olejków eterycznych. Kukurydza była najbardziej tolerancyjna, a komosa najbardziej wrażliwa na zastosowane preparaty. U kukurydzy maltodekstryna i mikrokapsułkowane olejki powodowały spadek względnej zawartości chlorofilu w liściach. Najwyższa dawka mikrokapsułkowanych olejków eterycznych, szczególnie z dodatkiem olejku z mięty lub kminku, powodowała największe ograniczenie liczby i suchej masy badanych chwastów. Podsumowując należy stwierdzić, że mikrokapsułkowane olejki eteryczne wpływają hamująco na początkowy wzrost chwastów i powinny być badane w warunkach polowych.
