Abstract

Plants have the ability to detect the presence of neighboring weeds through the R: RL ratio reflected on the surfaces of weed leaves. The role of the R: RL ratio as a weed management tool has not been sufficiently explored. It is believed that the competition of plants is due to the limitation of resources (water, light, space and nutrients). The competition of plants is initially triggered by the ratio of red to far-red (R: RL) that originates from neighboring plants, followed by a series of complex physiological processes, which exclude direct competition from resources. In this paper, the importance of the weed management system based on the quality of light is disclosed. In addition, mention is made of the crop - weed competition, as well as the perception of neighboring plants through the spectral composition of the light and how the shadow influences the management of weeds.
