  • Study uses farm data to aid in slowing evolution of herbicide-resistant weeds

    The widespread evolution of herbicide-resistant weeds is costing farmers, especially through decreases in productivity and profitability. Although researchers and industry personnel have made recommendations to slow this evolution, an understanding of the patterns and causes of the resistance has been limited. Diversifying the herbicide mechanisms of action (MOAs) has been recommended to stop the ...

  • Integrated weed management can reduce need for herbicides

    The use of herbicides on crops causes environmental concerns. A new French study assesses the performance of cropping systems to manage weeds and finds that these techniques could control arable weeds in the long-term and reduce reliance on herbicides. In Europe, herbicides provide the conventional means of managing weeds on farmland. Although effective, herbicides are expensive and can build up ...

  • The lurking menace of weeds

    Today more than a billion people in the world are hungry, the result of flawed policies mainly, but also of wars and revolutions and of natural hazards like floods, droughts, pests and diseases compounded, nowadays, by climate change. But one huge hunger-maker lurks largely unnoticed ... 'Maybe it's because weeds are not very spectacular,' says weed expert Ricardo Labrada-Romero.  'Droughts, ...

  • Weed control wheely important

    Using additional wheel track nozzles is the most useful thing growers can do to improve coverage in the sprayer’s wheel tracks when summer fallow spraying with non-residual, knockdown herbicides. Information that can help Western Australian growers improve weed control in wheel tracks this summer is contained in the Grains Research and Development Corporation (GRDC) Weed Control in ...

  • 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 ...

  • Weed Specialist: Try to Apply Fall Herbicide Treatments Before December

    Now is a good time for growers to apply herbicide treatments to their fields to control weeds and help ensure a good start for spring planting. In fact, anytime between now and the week of Thanksgiving is a good time for fall herbicide applications, according to a researcher from Ohio State University’s College of Food, Agricultural, and Environmental Sciences. Although growers may be busy ...

  • Buddleia weevil laying waste to weeds

    As large patches of buddleia are reduced to bare stems throughout the region, forest growers and biosecurity managers are applauding the miniature culprit responsible for the damage. The Chinese weevil, Cleopus japonicus was released in 2006 by Crown Research Institute Scion as a sustainable weed control measure. Scion identified the Cleopus weevil as a suitable candidate for biological control ...

  • USDA Seeks Public Review and Comment on Draft Environmental Impact Statement for Herbicide-Resistant Corn and Soybeans

    The U.S. Department of Agriculture's (USDA's) Animal and Plant Health Inspection Service (APHIS) released on Friday 3 2014 its Draft Environmental Impact Statement (DEIS) as part of its review to determine whether to deregulate genetically engineered (GE) corn and soybean plants that are resistant to several herbicides, including one known as 2,4-D. APHIS is performing an assessment of these GE ...

  • Decision could boost use of popular weed killer

    Faced with tougher and more resistant weeds, corn and soybean farmers are anxiously awaiting government decisions on a new version of a popular herbicide - and on genetically modified seeds to grow crops designed to resist it. Critics say more study is needed on the effects of the herbicide and they are concerned it could endanger public health. The Environmental Protection Agency is expected to ...

  • Beast of a weed creeping across Midwest from south

    It's a beast of a weed, creeping north into the Midwest from cotton country. Palmer amaranth can shoot up as high as 7 feet, and just one plant can produce up to a million seeds. Herbicide is increasingly futile against it, and the weed's thick stems and deep roots make it hard work to clear by hand. It can slash yields and profits when it gets out of control. Midwestern weed scientists are ...
