“…The negative effects of weedy rice include yield reduction, harvest quality deterioration, rice milling quality decrease, crop seed contamination, production cost increase, and land devaluation (Clavijo & Montealegre, 2010; Delouche et al, 2007). The importance and negative impact of weedy rice has been reported in many regions of the world, including Europe (Fogliatto, Vidotto, & Ferrero, 2012; Grimm, Fogliatto, Nick, Ferrero, & Vidotto, 2013; Messeguer, Marfà, Català, Guiderdoni, & Melé, 2004), Latin America (Arrieta‐Espinoza et al, 2005; Avila, Marchezan, & Menezes, 2000; Canal, Arnaude, Ortiz‐Domínguez, Valverde, & Fuentes, 2009; Clavijo & Montealegre, 2010; Federici et al, 2001), the United States (Burgos, Norman, Gealy, & Black, 2006; Delouche et al, 2007), and Asia (Cao, Li, Song, Cai, & Lu, 2007; Cao et al, 2006; Zhiwen et al, 2016). Weedy rice infestations have been found to have the capacity to reduce cultivated rice yields by up to 80% (Olsen, Caicedo, & Jia, 2007).…”
