This book was released on 2013-11-21 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technology is rapidly advancing in all areas of society, including agriculture. In both conventional and organic systems, there is a need to apply technology beyond our current approach to improve the efficiency and economics of management. Weeds, in particular, have been part of cropping systems for centuries often being ranked as the number one production cost. Now, public demand for a sustainably grown product has created economic incentives for producers to improve their practices, yet the development of advanced weed control tools beyond biotech has lagged behind. An opportunity has been created for engineers and weed scientists to pool their knowledge and work together to ‘fill the gap’ in managing weeds in crops. Never before has there been such pressure to produce more with less in order to sustain our economies and environments. This book is the first to provide a radically new approach to weed management that could change cropping systems both now and in the future.

Available in PDF, EPUB and Kindle. Book excerpt: Effective weed control is one of the most yield-limiting factors in organic corn and soybean production. Additionally, the amount of tillage needed to control weeds in organic practice is often criticized for its negative impacts on soil quality. This research was conducted in central Missouri from 2016-2017 to compare cultivation, flame application, between-row mowing, and hot water spray for in-season weed control in organic corn and soybeans. Between-row mowing and hot water application were paired with notillage and a crimped winter cover crop of cereal rye (Secale cereale L.). When weeds reached 10.2 cm, weed control practices were implemented and repeated as necessary until canopy closure. Grass and broadleaf weed biomass between crop rows was determined at multiple dates throughout the 2016 and 2017 seasons and in-row weed levels were determined at the final collection date for each crop each year. Broadleaf weed biomass at the end of the soybean season in 2016 was lower in the two treatments utilizing no-till and cover crops as primary weed control and hot water and mowing as secondary control. Soybean yield was adversely affected by flaming but not significantly different for the cultivation, mowing and hot water treatments. In 2017, soybean had less between-row grass biomass in the cultivation and flaming treatments than in hot water and mowing, but broadleaf levels were the same in the mowed treatment as the cultivated and flamed treatments. In 2016, grass biomass was lower in the no-till treatments between corn rows and higher in the crop rows than the other two treatments. Weed control treatments led to no significant differences in corn yield in 2016 and higher yields in the no-till treatments in 2017. In-row weed levels were significantly higher in corn in 2017 for the hot water treatment. Hot water at the levels applied in this research was not an effective weed control method. Since the overuse of cultivation can decrease soil organic matter levels and increase soil erosion, alternatives techniques are important to grant farmers the possibility to use their land for a long time. The crimped cover crop used in the no-till treatments limited weed growth in early-season corn and soybean and when coupled with between-row mowing is a potential alternative to cultivation in organic crop production. Flaming is also a potential alternative to cultivation in corn production.
Download or read book Herbicide Resistance and World Grains written by Stephen B. Powles and published by CRC Press. This book was released on 2001-03-13 with total page 328 pages. 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 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Weed Science and Weed Management in Rice and Rice-Based Cropping Systems will describe the history, production systems and practices of rice cropping systems in major rice-growing countries, and how the unique production practices affect crop-weed relationships which in turn affect weed management practices. It will also attempt to provide an understanding of the basic weed science principles as they apply to tropical cropping situations to be able to compare how weeds behave under multi-crop tropical systems and mono-crop mechanized temperate cropping systems. The ultimate purpose is to be able to apply these basic principles in order to develop improved, efficient, and economically and environmentally sustainable strategies in managing or controlling weeds. This book will discuss the various management methods: chemical, cultural, mechanical, biological, integrated, focusing on the most recent research, particularly on new herbicide chemistries and modes of action, molecular biology and weed genomics and on evolution of herbicide-resistant weeds. For non-chemical (mechanical) control, it will focus on recent developments on robotics and automated weed control and for biocontrol, on the new bioherbicides derived from plant and microbial toxins being developed in the past 5 years. On the most challenging problem in chemical control nowadays, the evolution of herbicide-resistant weeds, recent researches to elucidate resistance mechanisms and use of weed genomics to understand how weeds adapt and evolve resistance to herbicides and the search for practices that could delay adaptation capabilities are also discussed"--

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 pages. Available in PDF, EPUB and Kindle. 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).
