Project aims to tame wild radish impact in cropping regions
Wild radish and its resistance to herbicides is under scrutiny in Victoria’s Wimmera-Mallee cropping region. A Grains Research and Development Corporation “fast track project”, instigated by the GRDC’s southern Regional Cropping Solutions Networks (RCSN), aims to map the extent of herbicide resistance in wild radish and other broadleaf weeds and increase awareness about ...

Carbon Robotics Disrupts Farming Industry with Autonomous Weeders
Carbon Robotics, an autonomous robotics company, today unveiled its third-generation autonomous weed elimination robots. The Autonomous Weeder leverages robotics, artificial intelligence (AI), and laser technology to safely and effectively drive through crop fields to identify, target and eliminate weeds. Unlike other weeding technologies, the robots utilize high-power lasers to eradicate weeds ...

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 ...

Avoid Harvest Disappointment with Management Now
Each year the same issues appear across the country. Whether an issue is seen at emergence or while inspecting the success of a foliar program later in the season, many of these problems can be traced back to unforced and avoidable errors at planting. Soil, not the calendar, drives planting decisions. While we understand the excitement of spring, planting into wet, cold soils can be ...

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 ...

USDA approves new modified corn seeds, soybean seeds
The Agriculture Department has approved the use of genetically modified corn seeds and soybean seeds that are resistant to a popular weed killer. However, farmers won't be able to take full advantage of the seeds until the Environmental Protection Agency issues a second ruling allowing the use of Enlist, a new version of the 2,4-D weed killer that's been around since the 1940s. The EPA has said ...

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 ...

Research confirms first glyphosate resistant wild radish
The world’s first populations of glyphosate resistant wild radish will be announced at Perth’s Agribusiness Crop Updates, but researchers stress further cases can be minimised if farmers adopt diverse control strategies. Australian Herbicide Resistance Initiative (AHRI) research has confirmed glyphosate resistance in three populations of wild radish, all from different locations in ...

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 ...

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 ...

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 ...

Valor brings flexibility to summer weed control
New pre-emergent residual registrations for Valor herbicide in fallows and prior to planting summer crops greatly broadens crop rotation flexibility and boosts efforts in combating herbicide resistance. New registrations for Valor herbicide now enable it to be used for highly effective pre - emergent (residual) control of a broad range of problem weeds in fallow and prior to planting summer ...

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 ...

Pesticide levels decline in corn belt rivers
Concentrations of several major pesticides mostly declined or stayed the same in “Corn Belt” rivers and streams from 1996 to 2006, according to a new U.S. Geological Survey study. The declines in pesticide concentrations closely followed declines in their annual applications, indicating that reducing pesticide use is an effective and reliable strategy for reducing pesticide contamination in ...

Added bonus for grass weed control
Certis' straight flufenacet herbicides, Sunfire and System 50 have been granted an Extension Authorisation for Minor Use (EAMU) on Rye and Triticale, for the control of black-grass and annual meadow grass. Already widely used in barley and wheat crops, and showing good control of black-grass and other significant grass weeds, this comes as a welcome addition for growers of Rye and Triticale as ...

Clove Oil Tested for Weed Control in Organic Vidalia Sweet Onion
Weed control is one of the most challenging aspects of organic crop production. Most growers of certified organic crops rely heavily on proven cultural and mechanical weed control methods while limiting the use of approved herbicides. A new study of herbicides derived from clove oil tested the natural products' effectiveness in controlling weeds in Vidalia sweet onion crops. "Cultivation with a ...

EPA Announces Final Decision to Register Enlist Duo, Herbicide Containing 2, 4-D and Glyphosate/Risk assessment ensures protection of human health, including infants, children
The EPA is registering the herbicide, Enlist Duo with first-time ever restrictions to manage the problem of resistant weeds. The pesticide is for use in controlling weeds in corn and soybeans genetically-engineered (GE) to tolerate 2,4-D and glyphosate. The agency’s decision reflects a large body of science and an understanding of the risk of pesticides to human health and the environment. ...

EPA Seeks Comment on Proposed Decision to Register Enlist Duo Herbicide Containing the Choline Salt of 2,4-D and Glyphosate
The EPA is making available for a 30-day public comment period a proposed regulatory decision to register Enlist Duo containing glyphosate and the choline salt of 2,4-D for use in controlling weeds in corn and soybeans genetically engineered (GE) to tolerate 2,4-D. Weeds are becoming increasingly resistant to glyphosate-based herbicides and are posing a problem for farmers. If finalized, ...
