Abstract
Widespread use of synthetic herbicides in weed control could result in negative impact on human health and on the environment.
Natural compounds could be successfully used as bioherbicides because they are potentially more environmental friendly and safe.
Plants are an important source of active compounds.
In particular, many species belonging to the Labiate family produce essential oils containing compounds that could act as natural herbicides.
In this paper we report on preliminary studies about the effects on seed germination and plant growth of an oregano hybrid (Origanum vulgare L. ssp. virilidum x O. vulgare L. ssp. hirtum (Link) Iestwart). Experiments were done both in pots and in the field.
Increasing amounts of chopped leaves and stems of oregano were added to the soil.
In the pots, several weed species were sown, whereas naturally occurring infestation was evaluated in the field.
In comparison with the control, a reduced number of weeds was observed where oregano biomass was added.
The above-mentioned trend was more visible in the pots than in the field.
The results suggest that the hybrid of oregano used in the trial could be an interesting source of natural compounds effective against weeds.
Hence, further studies with this plant are likely to be successful.
