Evolution of Resistance to Auxinic Herbicides: Historical Perspectives, Mechanisms of Resistance, and Implications for Broadleaf Weed Management in Agronomic Crops

TL;DR: Recent advances in the auxin signal transduction pathway and its relation to auxinic herbicide mode of action are discussed and agronomic implications of the evolution of resistance to these herbicides are discussed in light of new auxinic Herbicide-resistant crops that will be commercialized in the near future.

Palmer Amaranth (Amaranthus palmeri) Management in Dicamba-Resistant Cotton

TL;DR: A field experiment was conducted in North Carolina and Georgia to determine B2XF cotton tolerance to Dicamba, glufosinate, and glyphosate and to compare Palmer amaranth control by dicamba to a currently used, nondicamba program in both glufo- and glyphosate-based systems.
Journal ArticleDOI

Survey of Nebraska Farmers' Adoption of Dicamba-Resistant Soybean Technology and Dicamba Off-Target Movement

TL;DR: Although dicamba-resistant (DR) soybean technology allowed farmers to achieve better weed control during 2017 than previous growing seasons, it is apparent that off-target movement and resistance management must be addressed to maintain the viability and effectiveness of the technology in the future.

Influence of Dicamba and Dicamba plus Glyphosate Combinations on the Control of Glyphosate-Resistant Waterhemp (Amaranthus rudis)

TL;DR: Results from these experiments indicate that, in the absence of crop competition, a single treatment of dicamba up to 0.56 kg ha−1 provides less than 62% control of glyphosate-resistant waterhemp, and sequentialdicamba plus glyphosate treatments targeting 7.5 cm plants are required to achieve at least 72% control.

Glyphosate-Resistant Giant Ragweed (Ambrosia trifida) and Waterhemp (Amaranthus rudis) Management in Dicamba-Resistant Soybean (Glycine max)

TL;DR: Results from this research indicate that dicamba applied once or sequentially and when timed appropriately to match the biology of the weed species can be utilized as a component of an integrated program for the management of GR weeds like giant ragweed and waterhemp in DR soybean.

Changes in Herbicide Use Patterns and Production Practices Resulting from Glyphosate-Resistant Crops'

Bryan G. Young
- 01 Apr 2006 - 
TL;DR: Although it is difficult to establish a clear relationship between the adoption of glyphosate-resistant crops and changes in other crop production practices, the increase in no-till and strip-t Till production of cotton and soybean between 1995 and 2002 may have been facilitated by glyphosate- resistant crops.

Farmer Perceptions of Problematic Corn and Soybean Weeds in Indiana1

TL;DR: Corn and soybean farmers across Indiana were surveyed in 2003 to determine the perceived importance of weeds at the state and district levels and supports the idea that educational programs focused on weed management should be tailored to geographic regions within Indiana.
Journal ArticleDOI

U.S. Grower Views on Problematic Weeds and Changes in Weed Pressure in Glyphosate-Resistant Corn, Cotton, and Soybean Cropping Systems

TL;DR: The long-term success of managing problematic weeds in GR cropping systems will require the development of multifaceted integrated weed management programs that include glyphosate as well as other weed management tactics.

Dicamba monooxygenase: structural insights into a dynamic Rieske oxygenase that catalyzes an exocyclic monooxygenation.

TL;DR: Four DMO structures are presented to provide a snapshot of a dynamic enzyme where metal binding and substrate binding are coupled to observed structural changes in the non-heme iron and catalytic sites and postulate an uncommon mode of non- heme iron binding trapped by theNon-catalytic Co(2+), which may be transiently present in the native enzyme during the catalytic cycle.
