Book excerpt: The use of herbicide weed control has been an integral part of farm management for several decades due to being an efficient and cost-effective alternative to mechanical weed control management. However, repeated use of broad spectrum herbicides has resulted in herbicide resistance in several weed species (Norsworthy et al., 2012). Although the indiscriminate use of herbicides has been linked to the quick and widespread adoption of herbicide resistant crop species (Fernandez-Cornejo et al., 2014), research indicates that herbicide resistance predated the introduction of bio-tech crops by several decades (WSSA, 2016). By the time that USDA began tracking the adoption of biotech soybean production in 2000, over half of US acreage were planted to herbicide-tolerant varieties and reached over 90% within 7 years (USDA NASS) (Figure 1). By 2013, 90% of corn and soybean acreage were planted to bio-tech cultivars including herbicide-tolerate only and stacked genes (Figure 1). Currently, 470 unique cases of herbicide resistance have been documented (Heap, 2016). Multiple herbicide-resistant weed species causes additional concern due to reduced herbicide options and increased weed control costs. Multiple herbicide resistance has been confirmed in economically important weeds including Palmer amaranth (Amaranthus palmeri) (Nandula et al. 2012), waterhemp (Amaranthus tuberculatus Sauer) (Bell et al., 2013), horseweed (Conyza canadensis L. Cronq.) (Davis et al. 2009), rigid ryegrass (Lolium rigidum Gaudim) (Owen et al. 2014), and kochia (Kochia scoparia (L.) Schrad.) (Foes et al. 1999) (see Heap, 2016, for more details on herbicide resistance weeds).

Available in PDF, EPUB and Kindle. Book excerpt: Written by experts from across the globe, Herbicide Resistance and World Grains evaluates the weed and herbicide management systems in major world grain crops such as soybean, maize, rice, and canola. The book examines the impact of transgenic crops and new technology on resistance management. It provides background information and offers practical guidelines for the management of herbicide resistant weeds with an emphasis on a systems approach. This book provides the how-tos of managing herbicide resistant weed populations in the major grain crops. The authors also explore the sociological and agronomic factors affecting farmers' adaptation of herbicide resistance management systems. With this in mind, they suggest that the recommended guidelines be global in scope but also applicable at local levels. Containing the most up-to-date information on the genetics and mechanisms of resistance, the book also includes models that can be used to make informed decisions on management alternatives and financial analysis of the cost and an update of the regulatory aspects of resistance management. Other books on this subject merely document the extent and spread of resistance but provide little information on what to do about it. Herbicide Resistance and World Grains contains practical solutions that can be used by researchers and practitioners alike.

This book was released on 2012-10-22 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preserving the efficacy of herbicides and of herbicide-resistance technology depends on awareness of the increasing resistance of weeds to herbicides used in agriculture and coordinated action to address the problem by individuals at the farm level and beyond. This summit served as a venue to bring the attention of important stakeholders to the issue and as an opportunity for experts from diverse disciplines to strategize in a coordinated way to address herbicide-resistant weeds. In convening stakeholders for this event, participants took a step toward a recommendation from the 2010 National Research Council report The Impact of Genetically Engineered Crops on Farm Sustainability in the United States that federal and state government agencies, private-sector technology developers, universities, farmer organizations, and other relevant stakeholders collaborate to document emerging weed-resistance problems and to develop cost-effective resistance-management programs and practices that preserve effective weed control. The summit provided the opportunity for stakeholders to explore the scientific basis of the emergence of herbicide resistance and to consider different perspectives on both opportunities and barriers to overcoming the problem of herbicide-resistant weeds. National Summit on Strategies to Manage Herbicide-Resistant Weeds contains a brief synopsis of key points made by each speaker at the summit.

Available in PDF, EPUB and Kindle. Book excerpt: Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to evaluate the potential of select mechanical tillage implements and reduced herbicide inputs in integrated high-residue corn and soybean systems. This integrated approach attempted to reduce the negative effects from herbicides and intense inversion tillage, while providing effective economical weed control. Treatments examined a vertical coulter, a rotary harrow, a high-residue rotary hoe, and a high-residue row cultivator in combination with soil-applied broadcast, soil-applied banded, or post-emergence herbicides. Conventional no-till using herbicides and a weedy check were included for comparison and the weed seed bank was supplemented to help ensure an effective assessment. Evaluation parameters included crop population, weed density, end of season weed biomass, surface residue, grain yield, and costs. Weed density, crop, and production year influenced the efficacy of the mechanical implements. Treatments including herbicides reduced weed density and weed biomass compared to treatments relying on mechanical control alone. The vertical coulter and rotary harrow controlled weeds similar to a herbicide burndown treatment in corn, while with the later planting date of soybean, this treatment was not as effective as a burndown herbicide. While the rotary hoe had a minimal impact on surface residue, weed densities were higher than with the soil-applied broadcast herbicide treatments. In addition, the rotary hoe did not increase weed control in banded herbicide treatments. Treatments that included banded herbicide tended to have better weed control than treatments that relied strictly on mechanical implements, but lower weed control than broadcast herbicides. Of the mechanical tools tested, the high residue cultivator was the most effective in reducing weed density and weed biomass, while maintaining crop yield. The greater reliance on mechanical implements reduced weed control cost, but tended to have higher breakeven prices due to lower yields. Overall, mechanical tillage implements alone did not provide adequate weed control, while integration with reduced herbicide inputs maintained acceptable weed control and competitive crop yields.

This book was released on 2020 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: With commercialization of multiple herbicide-resistant corn and soybean cultivars, producers have new management options for controlling herbicide-resistant weeds and volunteer corn. Corn-on-corn production systems are common in irrigated fields in southcentral Nebraska which can create issues with volunteer corn management in corn fields. Enlist corn contains a new multiple herbicide-resistant trait providing resistance to 2,4-D choline, glyphosate, and the aryloxyphenoxypropionate (FOPs). Field experiments were conducted in 2018 and 2019 at South Central Agricultural Laboratory near Clay Center, Nebraska with the objective to evaluate ACCase-inhibiting herbicides and herbicide application timing on volunteer corn control, Enlist corn injury, and yield. Glyphosate/glufosinate-resistant corn harvested the year prior was cross-planted at 49,000 seeds ha-1 to mimic volunteer corn in Enlist corn. Application timing of FOP herbicides had no effect on Enlist corn injury or yield, and provided 97-99% control of volunteer corn at 28 d after treatment (DAT). Clethodim and sethoxydim and pinoxaden provided 84-98% and 65-71% control of volunteer corn at 28 DAT, respectively; ii however, resulting in 62-96% Enlist corn injury and 69-98% yield reduction. While all FOP herbicides evaluated did not cause crop injury or yield loss, quizalofop is the only labeled product as of 2020 for control of volunteer corn in Enlist corn. Despite widespread adoption of dicamba/glyphosate-resistant soybean by producers in the United States, economic information comparing herbicide programs in glufosinateresistant and conventional soybean is not available. Field experiments were conducted in 2018 and 2019 at five locations across Nebraska to evaluate weed control, crop safety, gross profit margin, and benefit-cost ratios of herbicide programs with three unique sites of action in multiple herbicide-resistant and conventional soybean. Herbicides applied pre-emergence (PRE) that included provided 85-99% control for all weed species, and 72-96% weed biomass reductions at all locations. Herbicides applied POST provided 93- 99% control for all weed species, and 89-98% weed biomass reduction 28 DAT. For individual site-years, yield was similar for many herbicide programs in herbicideresistant and conventional systems. Gross profit margins and benefit-cost ratios were higher in herbicide-resistant systems than conventional systems, although price premiums for conventional soybean can help compensate increased herbicide costs.
