Integrated Weed Management: Soybean Seeding Rate and Residual Herbicide
ثبت نشده
چکیده
Increased soybean seed cost in recent years has generated interest in reducing seeding rates to maintain consistent economic returns. However, low seeding rates result in reduced established plant stands with slower canopy development, and canopy development is touted as an important element of integrated weed management (IWM). IWM practices have become even more important to slow the development and spread of glyphosate resistant weeds. The need to control herbicide resistant weeds has also renewed grower interest in using preemergence (PRE) residual herbicides (another IWM tactic). Therefore the objective of this study was to determine the effect of soybean seeding rate and PRE residual herbicide use on: Weed control Soybean canopy development Yield

Integration of Agronomic Practices with Herbicides for Sustainable Weed Management in Aerobic Rice
Till now, herbicide seems to be a cost effective tool from an agronomic view point to control weeds. But long term efficacy and sustainability issues are the driving forces behind the reconsideration of herbicide dependent weed management strategy in rice. This demands reappearance of physical and cultural management options combined with judicious herbicide application in a more comprehensive ...
متن کاملHerbicide-resistant crops and weed resistance to herbicides.
The adoption of genetically modified (GM) crops has increased dramatically during the last 3 years, and currently over 52 million hectares of GM crops are planted world-wide. Approximately 41 million hectares of GM crops planted are herbicide-resistant crops, which includes an estimated 33.3 million hectares of herbicide-resistant soybean. Herbicide-resistant maize, canola, cotton and soybean a...

The United States is the largest producer of maize in the world. Maize-soybean is the most prominent crop rotation in the Midwestern United States. Glyphosate-resistant volunteer maize is a problem weed not only in soybean, but also in continuous maize or sugarbeet rotations. Storm damage, harvesting problems, poor stalk quality, and insect damage, among other factors, can lead to kernel and ea...
متن کاملInfluence of herbicide tolerant soybean production systems on insect pest populations and pest-induced crop damage.
Conventional soybean weed management and transgenic herbicide-tolerant management were examined to assess their effects on soybean insect pest populations in south Georgia in 1997 and 1998. Soybean variety had very little impact on the insect species observed, except that maturity group effects were observed for stink bug, primarily Nezara viridula (L.), population densities on some sampling da...

Weed management systems used by sweet corn growers, including the role of atrazine, are poorly characterized. Management records of 175 fields throughout the major sweet corn production areas of the Midwest were surveyed from 2005 to 2007. Seventy-four percent of sweet corn fields in the Midwest were grown in rotation with soybean or corn. Interrow cultivation was used on 48% of fields, and atr...
