  • Identifying factors in Atrazine’s reduced weed control

    Invasive broadleaf weeds can destroy corn crops and fallow fields. Farmers use the chemical atrazine in herbicides to protect their plants. Despite atrazine’s controversial environmental impacts, it can provide long term residual control of many weed species. However, the loss of atrazine’s effectiveness has been a challenge for farmers in northeastern Colorado. In a collaborative ...

  • Biological control of weeds via their own aromas

    Plant experts in the Netherlands can still become enthusiastic about a special variety of broomrape. Farmers in southern countries, however, are less impressed because broomrape and its ‘sister’ striga are considered a harmful weed in these regions. Research in the Laboratory of Plant Physiology of Wageningen University shows how useful insects that can control this weed may lend a ...

  • USDA Announces Measures to Help Farmers Diversify Weed Control Efforts

    Agriculture Secretary Tom Vilsack today announced several steps that the U.S. Department of Agriculture (USDA) is taking to address the increase of herbicide resistant weeds in U.S. agricultural systems. "Weed control in major crops is almost entirely accomplished with herbicides today," said Vilsack. "USDA, working in collaboration with the Environmental Protection Agency, must continue to ...

  • Herbicide reduction can preserve crop yields as well as biodiversity benefits of weeds

    Pesticide-sparing approaches to farming do not have to compromise on crop yields, new research suggests. A study that explored the impact of reduced herbicide use across a variety of different farming contexts found that herbicideefficient systems could be just as productive as conventional systems — and more so than organic systems — whilst having other important environmental ...

  • EPA Registers Enlist Duo Herbicide --- Enlist Weed Control System Now Approved

  • UF/IFAS researchers use pigs to root out problem weeds

    Sometimes, the old-fashioned ways are the best ways. Back before chemical pesticides and herbicides, farmers had to come up with ways to kill the weeds that took over their fields. One method used “back in the day” was letting pigs loose in fields that were not being used for crops for a season and allowing the pigs to do what they do naturally: dig up the roots of weeds and ...

  • Rapid Spread of Glyphosate-Resistant Weeds Spurs New Initiative: Respect the Rotation

    Ag Sector Members Gather in Memphis to Build ConsensusMEMPHIS, TN -- (Marketwire) -- 07/15/10 -- In light of rapid expansion of glyphosate-resistant weeds, a cross-section of weed management, tillage and agronomy experts met to discuss an initiative designed to protect weed control options for years to come. The initiative, called Respect the Rotation, is being facilitated by Bayer CropScience ...


  • Organic mulch lets insect pollinators do their job

    As interest in organic agricultural and horticultural practices continues to grow, so does the need to identify alternative weed control practices. Mulching, a common practice used to control weeds and reduce the need for tillage, can also reduce insect pollinators' exposure to harmful pesticides; however, finding the right mulch materials that allow pollinators to flourish can be challenging. ...

  • Big society can help tackle ragwort risk

    Tackling Common Ragwort can be a practical example of the Big Society in action, Agriculture Minister Jim Paice said today. Tackling Common Ragwort can be a practical example of the Big Society in action, Agriculture Minister Jim Paice said today. With the Common Ragwort season in full bloom, Mr Paice is calling on landowners, local groups and nature-lovers to work together to ...

  • Transitioning to organic farming

    As the organic food trend continues to grow; more farmers are converting from conventional agriculture to organic production. One of the fastest growing markets in the U.S. is the production of organic milk. The growth of this industry has prompted many farmers to transition their land to organic feed grain production. With transition on the rise, it is necessary for these farmers to have ...

  • EPA OIG Will Evaluate EPA’s Management of Resistance Issues Related to Herbicide Tolerant GE Crops

    On March 25, 2016, the U.S. Environmental Protection Agency’s (EPA) Office of Inspector General (OIG) sent a memorandum to Jim Jones, Assistant Administrator, Office of Chemical Safety and Pollution Prevention (OCSPP), announcing that it plans to begin preliminary research to assess EPA’s management and oversight of resistance issues related to herbicide tolerant genetically ...

  • War on willows

    Willows are major environmental weeds of riverbank habitats across much of south-eastern Australia. They obstruct water flow, increase water temperature, change water chemistry and can displace native riverine plant species. A CSIRO project looking at the reproductive ecology and dispersal ability of the most aggressive invasive species of willows in Australia is providing urgently ...

  • Sandwich system found effective in organic apple orchards

    In organic apple orchards, one of the most serious challenges for growers is determining ways to limit weed competition while improving soil quality and ensuring high yields of quality apples. Scientists from the Swedish University of Agricultural Sciences published a study of orchard floor management systems (HortScience, March 2015) that revealed the benefits of using "sandwich systems" in ...

  • GM crops could reduce need for herbicides

    Analysis of large-scale European field trial data reveals that lower quantities of herbicides are applied to crops genetically modified for herbicide-resistance compared with conventionally grown crops. However, the data also suggest that biodiversity may be reduced if genetically modified (GM) crops are grown widely. Transgenic crops are currently grown in 22 countries across the world, ...
