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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

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 ...

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 ...

History sheds revealing light on crop sequencing
Forty years of crop sequencing trials have recently been collated by the Department of Agriculture and Food WA (DAFWA), giving Western Australian grain growers real insights into the rotational benefits of break crops. Representing more than 160 crop sequence experiments, the results were presented by DAFWA’s Mark Seymour at the Grains Research and Development Corporation (GRDC) supported 2009 ...

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 ...

Product Auto Hydraulic Weeder
JAGODA JPS celebrate the 21 years anniversary by announcing a new product Auto hydraulic weeder. The new product is designed for mechanical weed control in fruit and orchard trees. This reduces the cost of maintenance and facilitates keeping these crops. The auto hydraulic weeder machine is perfect for organic fruit farming and orchard trees, can significantly reduce or even eliminate the use ...

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 ...

Kansas City pesticide manufacturer to pay $6,000 civil penalty for importing misbranded pesticide from Argentina (MO)
PBI-Gordon Corporation, a Kansas City, Mo., pesticide manufacturer, has agreed to pay a $6,000 civil penalty to the United States to settle allegations related to the importation of more than 147 tons of a misbranded pesticide from Argentina. According to a consent agreement and final order filed in Kansas City, Kan., PBI-Gordon Corporation violated the Federal Insecticide, Fungicide and ...

EPA, federal and state agencies, rice growers, industry act to protect endangered salmon and steelhead trout in California
Today, the U.S. Environmental Protection Agency and National Oceanic Atmospheric Administration (NOAA) Fisheries, in cooperation with state agencies, rice growers and industry, announced an agreement to create federally enforceable restrictions of the pesticide thiobencarb, an herbicide used on rice crops, to protect threatened and endangered salmon and steelhead trout in California. ...

Common Pesticide Reduces Food Value of Algae
SILVER SPRING, Maryland (ENS) - Researchers with the NOAA National Centers for Coastal Ocean Science have identified negative effects of the commonly used herbicide atrazine on phytoplankton, the free-floating algae that form the base of the food chain for aquatic animals. Published in the current issue of the journal 'Pesticide-Biochemistry and Physiology,' the study indicates protein levels ...

Deep ploughing reduces diversity and number of earthworms
Less invasive soil preparation methods in farming, such as harrowing, have a positive impact on the numbers, biomass, and species richness of earthworms, unlike conventional ploughing, according to new research. The long-term study compared the results of five different methods of soil preparation on agricultural land in Germany over a ten-year period. Earthworms play a major role in the ...

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, ...

NRDC Petitions EPA to Save the Monarch Butterfly
Skyrocketing use of the weed-killer glyphosate, first marketed as “Roundup,” is devastating monarch butterfly populations, and new safeguards should be put in place immediately to save the iconic species from further decline, the Natural Resources Defense Council said today. In a petition filed with the Environmental Protection Agency, NRDC said current uses of glyphosate are causing ...

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 ...
