Evaluation of Very-long-chain Fatty Acid-inhibiting Herbicides in Arkansas Rice Production
Author: John Ansley GodwinPublisher:
ISBN:
Category : Herbicides
Languages : en
Pages : 238
Book Description
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.

Pest Management in Rice

Pages : 553
Book Description
The four-day international Conference on Pest Management in Rice, which is the subject of this volume, was the third in an ongoing series of meetings on tropical crops organised by the Pesticides Group of the Society of Chemical Industry, London. The participants came from both the public and private sectors and from many different countries. All the major groups of pests-weeds, microorganisms, arthropods and rodents-were considered, as the organisers believe that it is necessary to address the total pest management problems in each particular growing area, and the variety of the papers indicates the importance of a multi disciplinary approach to their solution. Rice is one of the most important world crops and is the major source of food for around 60% of the world's population, with a world production of 500 million tonnes from 150 million hectares of land. Since world stocks amount to only two months supply, many people are at risk from famine. Moreover, it has been esti mated that the world requirement in 2020 will be about 760 million tonnes, an increase of 50%. This pressure of population on food makes efficient pest management vital and is the reason for bringing together experts from all over the world to this major conference.
Rice Research in Asia
Author: Robert Eugene EvensonPublisher: IRRI
ISBN: 0851989977
Category : History
Languages : en
Pages : 430
Book Description
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.
Herbicides
Author: Andrew PricePublisher: BoD – Books on Demand
ISBN: 9535111124
Category : Technology & Engineering
Languages : en
Pages : 666
Book Description
Herbicide use is a common component of many weed management strategies in both agricultural and non-crop settings. However, herbicide use practices and recommendations are continuously updated and revised to provide control of ever-changing weed compositions and to preserve efficacy of current weed control options. Herbicides - Current Research and Case Studies in Use provides information about current trends in herbicide use and weed control in different land and aquatic settings as well as case studies in particular weed control situations.
