  • 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.

Scion identified the Cleopus weevil as a suitable candidate for biological control ...

  • 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.

  • EPA approves uses of weed killer Dicamba

    The Environmental Protection Agency (EPA) granted a conditional registration for new uses of the herbicide dicamba, a Monsanto “agrochemical,” on genetically engineered (GE) cotton and GE soybean. In a Final Registration document issued yesterday, ...

  • 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 ...

  • Ecological thermal weed-killing system with hot foam

    The “Schiumone”  (Big Foam)  is an  ecological thermal weed-killing machine for vineyards and tree crops in general, able to produce hot foam and distribute it a targeted way under the rows of the trees. When the temperature of the vegetable fiber exceeds 60° occurs the collapse of the proteins and within a few days the drying of the same. Since the foam has an ...

  • Overseas Lab Seeks U.S. Weed Control `Recruits`

    The search is on for insects, mites, microbes or nematodes that could be used in a biologically based approach to controlling silverleaf nightshade, an invasive weed from the Americas that has spread to southern Europe, Africa, India, Australia and elsewhere. According to U.S. Department of Agriculture (USDA) entomologist Walker Jones, the perennial weed, Solanum elaeagnifolium, is being targeted ...

  • 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 ...

  • Ohio State Guide to Weed Identification Available for Growers

  • Climate change may wake up ‘sleeper’ weeds

    Weeds cost Australia more than A$4 billion a year either in control or lost production and cause serious damage to the environment. In an address today in Perth to the GREENHOUSE 09 conference on climate change, CSIRO researcher, Dr John Scott, said, however, that those cost estimates were only based on the damage caused by weeds known to be active in Australia. “Out there, throughout the nation, ...

  • 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 ...

  • Warming could change SA’s weed pests

    The report; Climate Change and Invasive Plants in South Australia, used climate projections to 2080 to examine how weeds may shift in range across the State. Detailed profiles are provided for 13 weed species, including options for managing them under climate change. Lead-author, Dr Darren Kriticos from CSIRO’s Climate Adaptation Flagship, said projections of future climate scenarios ...

  • 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 ...
