| Popis: | Mowing weeds in rice paddy field ridges is essential for weed management. However, excessive mowing causes the dominance of the Poaceae weeds, which are host plants for rice stink bugs. In this study, the authors hypothesized that high mowing is more effective than low mowing in decreasing the dominance of Poaceae weeds. The dominance of the Poaceae weeds between high mowing (cut at a height of 5–10 cm) and low mowing (cut at ground level) was compared across 5 sites. As a result, the cover-abundance ratings of the Poaceae weeds were lower in the high mowing plots than that in the low mowing plots in all sites. In addition, the biodiversity index was higher in the high mowing plots than in the low mowing plots in each site. It was concluded that the increased mowing height effectively decreased the dominance of Poaceae weeds and this can be used as a strategy for controlling rice stink bugs. |
