  • 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 ...

  • Breakthrough corn herbicide receives US EPA approval

    Syngenta announced today that it has received US EPA approval for its breakthrough corn herbicide, ACURON™. The first sales of the product to US growers will take place this year. In the USA herbicide resistance, notably to glyphosate, is increasing with infestations of broadleaf weeds in corn up 50 percent in the past four years. ACURON has been shown to improve control of more than 70 ...

  • 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 ...

  • Soil pollution comes under scrutiny

    Soil pollution, due mostly to human activities that leave excess chemicals in soils used to grow food, took centre stage at the 5th Global Soil Partnership (GSP) Plenary Assembly held at FAO headquarters this week. Excess nitrogen and trace metals such as arsenic, cadmium, lead and mercury can impair plant metabolism and cut crop productivity, ultimately putting pressure on arable land. When they ...

  • 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 ...

  • Grass strips help curb erosion, herbicide transport

    Grass filter strips placed in riparian zones not only curb soil erosion, but can help block and degrade the widely used herbicide atrazine, Agricultural Research Service (ARS) scientists report. Atrazine has been used extensively to suppress weeds in corn production for decades, but because it's applied directly to soil it's especially prone to losses in surface runoff. The contamination of ...

  • 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. In the global market, acetochlor, alachlor, metolachlor and butachlor are the main amide herbicides in terms of sales volume.   China is one of 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 ...

  • Can herbicides increase pancreatic cancer risk?

    There is only a small chance of recovering from pancreatic cancer. This type of cancer has been linked to a number of risk factors, including smoking, but a new study suggests that pancreatic cancer may also be associated with exposure to certain herbicides. Other risk factors, in addition to smoking, that have been associated with a greater chance of developing pancreatic cancer include ...

  • 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, ...

  • 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 ...

  • NRDC: Urgent Herbicide Review Needed to Stem Monarch Butterfly Decline

    Conservation experts in Mexico today announced that a record low number of monarch butterflies returned this year to their wintering grounds in the mountains of Mexico and their annual migration is at “serious risk of disappearing.” Monarchs, which migrate from Mexico across North America and back every year, have been in serious decline since the 1990s. Experts believe that the ...

  • Dow AgroSciences Statement – Closing of the EPA Comment Period for Enlist Duo™ herbicide

    Dow AgroSciences looks forward to the next steps in the registration process for Enlist Duo™ herbicide. The United States Environmental Protection Agency (EPA) has now closed the comment period on its proposed decision to register Enlist Duo, the herbicide for use with the Enlist™ Weed Control System. The close of the comment period comes as ...

  • Ecuador sues Colombia to stop anti-coca herbicide spray

    The government of Ecuador this week filed suit at the International Court of Justice against the government of Colombia, in an effort to stop or restrict aerial anti-coca spraying that has allegedly sickened people on the Ecuadorean side of the border and harmed livestock, farmland, and sensitive, ecologically diverse rainforest areas. The lawsuit follows seven years of persistent but ...

  • EPA issues stop sale order to dupont on sale and distribution of imprelis herbicide

    The U.S. Environmental Protection Agency (EPA) today issued an order to E.I. DuPont de Nemours (DuPont) directing the company to immediately halt the sale, use or distribution of Imprelis, an herbicide marketed to control weeds that has been reported to be harming a large number of trees, including Norway spruce and white pine. The order, issued under the Federal Insecticide, ...

  • WSP Environment & Energy’s John Simon publishes article on herbicides

    US-based Executive Vice President John Simon, as editor of the esteemed publication Remediation Journal, has written an 'Editor's Perspective' article titled 'Atrazine Becomes Important Regulatory Issue'. In his article, John deals with the recent controversy behind the herbicide atrazine. Recent attention to atrazine has increased the awareness of the widespread agricultural use of the chemical ...

  • Some plants are more sensitive to herbicides during reproductive stages of life cycle

    This study assessed the effects of herbicides on non-target plants in Denmark and Canada. The findings showed that some plants are more sensitive to herbicides in the reproductive stages of their life cycle and can experience delays in flowering and reduced seed production. The authors say future ecological assessments should consider reproductive outcomes. Herbicides are some of the most widely ...

  • How to Keep Specialty Crops Safe from Herbicide Drift

    Ohio’s corn and soybean growers could soon be spraying a lot more of two powerful herbicides on their fields. That’s why agricultural experts from The Ohio State University are offering tips on how to keep those herbicides from getting onto other crops, especially valuable specialty crops such as grapes. Doug ...
