Abstract
Presently, chemical control is the most used method for plant
protection. However, it is not an approach that is environmentally
sustainable. Alternative IPM methods include biological control such as
Allelopathy can be a good alternative in plant protection.Allelopathy is
defined as a direct or indirect interaction, whereby allelochemicals
released by one organism influence the physiological processes of other
neighboring organisms.Laboratory experiments were conducted to investigate
the allelopathic effect of five weeds, Eriochloa villosa (ERIVI), Panicum
miliaceum (PANMI), Cannabis sativa (CANSA), Sorghum halepense (SORHA),
Asclepias syriaca (ASCSY) on germination and growth of wild mustard
(Sinapis arvensis L.). These weeds are dangerous during field cultivation
and their weed control is difficult.The extracts from the leaves and stem
were used to examine the potential of inhibition of germination, root
length, shoot length and full plant growth.The phenomenon of allelopathy
was detected in the examined plants. In the case of plants, the
allelopathic effect also increased with increasing concentration. The
results show that extracts of Johnson grass had the most significant
inhibition effect of growth and seed germination.
