Because of the evolution of herbicide-resistant weeds, such as barnyardgrass and red rice in rice, there is a need for alternative herbicide sites of action. Very-long-chain fatty acid (VLCFA)-inhibiting herbicides are not labeled for use in U.S. rice production; however, this site of action (SOA) has been used with success in Asian rice. The VLCFA-inhibiting herbicides pethoxamid, pyroxasulfone, acetochlor, and S-metolachlor were evaluated for rice tolerance and control of commonly problematic weeds in Arkansas rice at various rates and application timings. Pyroxasulfone and S-metolachlor were deemed unfit for use in rice production because of negative effects on rice visual injury, rough rice yield, height, shoot density, and heading. Pethoxamid and acetochlor were used with little detriment to the rice crop when applied no earlier than the 1-lf growth stage. Along with minimal rice injury, pethoxamid controlled barnyardgrass all season when used in a program with other common rice herbicides such as clomazone, imazethapyr, or quinclorac. Considering the minimal injury observed, pethoxamid and acetochlor should be considered for integration into U.S. rice production to represent a unique herbicide SOA to use in rotation, sequential application, or tank mixtures with other rice herbicides. Nomenclature: Acetochlor; pethoxamid; pyroxasulfone; S-metolachlor; barnyardgrass, Echinochloa crus-galli (L.) Beauv.; red rice, Oryza sativa var. sylvatica L.; rice, Oryza sativa L. Key words: weed control, herbicide-resistant weeds, herbicide sites of action.

In order to achieve economic efficiency, research organizations have established rigorous, quantitative methods for priority setting. One such organization, the Rockefeller Foundation, has drawn on this report to help determine the research goals it should emphasize in its funding. A review of the problem of priority setting is presented followed by a discussion of approaches that have been used previously. Several chapters demonstrate how a number of areas of plant science research have contributed to gains in rice productivity and also assess the current challenges of genetic improvement and pest control. The economic framework for priority setting and previous methods are reviewed, followed by a series of country case studies which provide more practical applications.
