Silencing Seed Dormancy Genes to Mitigate Risk of Transgene Flow to Weedy Rice
… fitness of weeds. SD-enhancing genes cloned from weedy rice include <em>SD7-1, SD7-2, SD12a, SD12b, and SD12c.</em> The goal of this study was to develop a transgenic mitigation (TM) strategy using SD gene-silencing structures as mitigating factors to reduce the risk of transgene flow to wild/weed …

The Impact of Herbicide-Resistant Rice and Hybrid Rice Technology on Weedy Rice Evolution
<p>Weedy rice (Oryza sativa L.) competes aggressively with rice, reducing yields and grain quality. ClearfieldTM rice, is nontransgenic herbicide-resistant (HR) rice introduced in 2002 to control weedy rice, has resulted in ALS-resistant weedy rice due to gene flow. Volunteers of ClearfieldTM rice …

Evaluation of Benzobicyclon in Midsouth Rice (Oryza sativa) Production Systems
<p>Controlling weedy rice postemergence is challenging for rice producers in the United States because of the lack of herbicide options. Weedy rice is genetically similar to cultivated rice, thus making it difficult to control with mid-season postemergence herbicide applications without also …

Evaluation of Fenclorim Safener for Use in Rice with Group 15 Herbicides
… to control problematic weeds has caused Arkansas rice (Oryza sativa L.) production to pursue alternative sites of action. Currently, very long-chain fatty acid elongase inhibitors are not labeled for U.S. rice production but have been widely used for Asian rice production systems. Previous …

Evaluation of Topramezone for Use in Rice (Oryza sativa L.) Production
… herbicides, is a growing concern to rice producers worldwide. Barnyardgrass, one of the most problematic weeds in rice cropping systems, alone has been found to be resistant to four herbicide sites of action (SOA) in certain populations, leaving growers no options for control. This …

Evaluation of Benzobicyclon for use in Midsouthern Rice (Oryza sativa) Systems
… new herbicide site of action (SOA) is needed by rice (Oryza sativa L.) producers in the Midsouth for the control of problematic and herbicide-resistant weeds. Currently, six problematic weeds are relevant to Midsouthern rice producers because of resistance to at least one SOA, if not more. Gowan …
