Species in the genus Echinochloa present a major management challenge in rice production worldwide. Understanding the herbicide resistance status of Echinochloa is crucially necessary for raising awareness and developing effective management programs. This study investigated the status of herbicide resistance by junglerice, the predominant Echinochloa species in Texas rice fields. A total of 58 junglerice populations collected during a field survey (2015–2016) of Texas rice fields were screened with two preemergence herbicides; quinclorac (Group 4) and clomazone (Group 13); and four postemergence herbicides: fenoxaprop (Group 1), imazethapyr (Group 2), quinclorac (Group 4), and propanil (Group 5). At 21 d after application (DAA) of herbicide treatments, percent survival, and percent visible injury data were recorded. Based on the injury levels observed, the populations were categorized into being either putative resistant (≤50% injury), less sensitive (51% to 90% injury), or susceptible (≥91% injury). Results showed that herbicide resistance is widespread among the junglerice populations surveyed in Texas. About 5% of the populations showed multiple resistance to all four postemergence herbicides that were evaluated. Dose-response assays were conducted on the populations with the lowest injury ratings to determine the extent of resistance and revealed a >70-fold resistance to imazethapyr, a >15-fold resistance to propanil, and a 3-fold resistance to fenoxaprop, compared with a susceptible check. The results suggested that integrated management practices are needed to manage junglerice in Texas rice production.
