Available in PDF, EPUB and Kindle. Book excerpt: Edited by a recognized leader in the field, Herbicide-Resistant Crops is the first book to cover all of the issues related to the controversial topic of herbicide-resistant crops. It provides extensive discussions of the modern biotechnological methods that have been used to develop such crops, and reviews the implications - both positive and negative - of developing crops that are resistant to herbicides. The creation and anticipated applications of specific herbicide-resistant crops are also discussed. In addition, the book covers the potential impact of herbicide-resistant crops on weed management practices and the environment, and presents issues related to the regulation and economics of these crops. The editor has brought together a diverse group of professionals, representing the several distinct areas impacted by the new technology of herbicide-resistant crops. The wide range of viewpoints presented in this book creates a balanced and complete survey, providing a notable contribution to the literature.

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory and greenhouse studies were conducted to determine the effect of temperature, solution pH, water stress, and planting depth on cutleaf eveningprimrose germination. Field studies were conducted to measure growth parameters of cutleaf eveningprimrose throughout the fall season. When treated with constant temperature, the optimum germination of cutleaf eveningprimrose occurred at 24 C. Onset, rate, and total germination were greatest in an alternating 20D 5 C temperature regime. Germination decreased as solution pH increased. Germination decreased when seed was subjected to increased water stress. Emergence was optimum when seed were buried at depths of 0.5 cm. Cutleaf eveningprimrose control was maximized when 2, 4-D was applied in mixture with glyphosate or paraquat. Five studies were conducted at Clayton, Rocky Mount, and Lewiston-Woodville, NC, in 2001 and 2002, to evaluate weed management, crop tolerance, and yield in strip- and conventional-tillage glyphosate-resistant cotton. The addition of S-metolachlor to either glyphosate formulation increased control of broadleaf signalgrass, goosegrass, large crabgrass, and yellow foxtail 14 to 43% compared to control with glyphosate alone. S-metolachlor was not beneficial for late season control of entireleaf morningglory, jimsonweed, pitted morningglory, or yellow nutsedge. The addition of S-metolachlor to either glyphosate formulation increased control of common lambsquarters, common ragweed, Palmer amaranth, smooth pigweed, and velvetleaf 6 to 46%. The addition of a late postemergence-directed spray (LAYBY) treatment of prometryn plus MSMA increased control to greater than 95% for all weed species regardless of early-postemergence (EPOST) treatment, and control was similar with or without S-metolachlor EPOST. Cotton lint yield was increased 220 kgD a with the addition of S-metolachlor to either glyphosate formulation compared to yield from glyphosate alone. Addition of the LAYBY increased yields.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cotton and soybean resistant to glyphosate are widely planted in the United States. Ninety-five percent of the cotton and 85% of the soybean in North Carolina is glyphosate-resistant (GR). Rapid adoption of the technology is attributed to broad spectrum weed control, convenience of glyphosate-based weed management systems, and greater rotational crop flexibility. Corn resistant to glyphosate is less widely grown, but plantings are expected to increase. Wide-spread planting of GR crops in the United States and glyphosate patent expiration has led to a proliferation of glyphosate products. Growers have questioned their advisors on efficacy and crop tolerance of many of these products. Field experiments were conducted to evaluate 10 glyphosate products, representing isopropylamine, diammonium, and potassium salts, applied postemergence (POST) and postemergence-directed (PDIR) at 630 and 1680 g ae/ha for GR corn and GR cotton tolerance and weed control. There were no differences among products for control of six annual grass and 10 annual broadleaf weed species. No injury to corn from any glyphosate product at 630 or 1680 g/ha or to cotton from 630 g/ha was noted at any of seven locations. ClearOut 41 Plus"! an isopropylamine salt of glyphosate, and Roundup WEATHERMAX"! a potassium salt of glyphosate, applied POST at 1680 g/ha injured cotton 27 to 30% and 10 to 17%, respectively, at 3 of 7 locations. No cotton injury was noted with Glyfos®, Glyfos® X-TRA, Glyphomax"! Gly Star"!Original, Roundup Original"! Roundup UltraMAX®, Touchdown®, or Touchdown Total"! No differences were noted among glyphosate products or between rates for corn or cotton yield or cotton fiber properties. Field studies were conducted at six sites during 2002 and 2003 to evaluate weed control and glyphosate-resistant corn response to glyphosate and nicosulfuron plus atrazine applied POST as affected by PRE herbicide and timing of POST herbicide.

Download or read book Evaluation of Weed Management and the Agronomic Utility of Cotton Grown on a 15 Inch Row Configuration and the Biology and Ecology of Doveweed written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a century, farmers planted cotton in rows spaced 91-cm or more apart. Row spacing was dictated primarily by equipment for cultivation, which was initially draft animals and later, tractors. Harvesting equipment also was designed to accommodate these wide row spacings. Recent advances in technology, especially herbicide-resistant cotton and the ability to spindle-pick cotton in 38-cm rows, have increased the potential for cotton production in narrow rows. Field experiments were conducted to evaluate weed management systems in glufosinate-resistant cotton planted in 38- and 97-cm rows. Greater than 90% control of annual grasses and Amaranthus spp. in 2004 and Ipomoea spp. in both years was obtained in narrow-row cotton receiving glufosinate applied early postemergence (EPOST) and mid-postemergence (MPOST) to 2- and 6-leaf cotton, respectively. With good early season control by glufosinate and rapid canopy closure, there was little benefit from pendimethalin, fluometuron, or pyrithiobac applied preemergence (PRE), S-metolachlor or pyrithiobac mixed with glufosinate applied MPOST, or trifloxysulfuron applied late postemergence (LPOST) to 11-leaf cotton. In 2005, glufosinate alone applied EPOST and MPOST did not adequately control annual grasses and Amaranthus spp. Pendimethalin applied PRE alone or mixed with fluometuron or pyrithiobac increased control to greater than 90% and increased yields 59 to 75%. Pendimethalin PRE followed by S-metolachlor or pyrithiobac mixed with glufosinate at MPOST was no more effective than pendimethalin alone. Without PRE herbicides, trifloxysulfuron applied LPOST increased Amaranthus but not annual grass control. Cotton row spacing had no effect on cotton yield and little effect on weed control. Weed control and yield in narrow-row cotton with a PRE herbicide plus glufosinate applied twice was similar to that in wide-row cotton with a PRE herbicide, glufosinate applied twice, and trifloxysulfuron plus prometryn plus MSMA app.

Download or read book Weed and Crop Resistance to Herbicides written by Rafael de Prado and published by Springer Science & Business Media. This book was released on 1997-05-31 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Córdoba, Spain. This book will be a good reference source for research scientists and advanced students.
