  • Prior herbicide use—not irrigation—is critical to herbicide efficacy

    Crop and herbicide use history are more critical to herbicide efficacy and environmental safety than the timing and amount of irrigation water used, according to Agricultural Research Service (ARS) scientists. ARS plant physiologists Dale Shaner and Lori Wiles made this discovery from ongoing experiments on two irrigated fields at Colorado State University (CSU) at Fort Collins, Colo. Shaner and ...

  • Herbicide-tolerant crops can improve water quality

    The residual herbicides commonly used in the production of corn and soybean are frequently detected in rivers, streams, and reservoirs at concentrations that exceed drinking water standards in areas where these crops are extensively grown. When these bodies of water are used as sources of drinking water this contamination can lead to increased treatment costs or a need to seek alternative sources ...

  • 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, ...

  • China Amide Herbicides Market Survey Report

    With more than 50 years’ development, amide herbicides have become the most widely applied herbicide category in the world, playing a more and more important role in weed control thanks to its high popularity and low application cost.

  • 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 ...

  • Low level herbicide use can damage potato reproduction

    Currently, plant testing in the United States to determine potential ecological risks from chemical pesticides to nontarget plants requires two tests, both of which use immature plants. Protection of the plant development and reproduction are not considered, unlike tests required for the protection of animals. Past research conducted by the USEPA and others have shown that plant ...
