Intra-row weeding possible with vision systems
Researchers of Wageningen University & Research, BU Greenhouse horticulture, developed weeding machines which are able to do intra-row weeding. Our experts in robotics were responsible for the detection of weed based on camera images. This development brings great advantage in weed control on the field, improving crop size and quality. When growing organic vegetables on the field, one of ...

The lurking menace of weeds
Today more than a billion people in the world are hungry, the result of flawed policies mainly, but also of wars and revolutions and of natural hazards like floods, droughts, pests and diseases compounded, nowadays, by climate change. But one huge hunger-maker lurks largely unnoticed ... 'Maybe it's because weeds are not very spectacular,' says weed expert Ricardo Labrada-Romero. 'Droughts, ...

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 ...

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 ...

Bayer CropScience opens Weed Resistance Competence Center in Frankfurt, Germany
Herbicide-resistant weeds are a growing global problem. The official opening of Bayer CropScience’s Weed Resistance Competence Center (WRCC) in Frankfurt on 19 November is a major step forward in tackling weed resistance, as it will develop new weed control strategies, and share knowledge within the global community of farmers, agronomists and scientists. Understanding weed resistance and ...

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 ...

Count me out of counting seeds
One, two, three, four, five. One, two, three, four, five. Over and over and over. That’s the dull routine of any researcher or student tasked with counting weed seeds. But just like technology has made many things in life faster and easier, relief may be coming for seed counters as well. A team of researchers at the University of Arkansas, Auburn University and North Carolina State ...

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 ...

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 ...

Understanding why rye works as a cover crop
Agricultural Research Service (ARS) scientists may soon find a way to enhance the weed-killing capabilities of a cereal grain that enriches the soil when used as a winter cover crop. Rye is often grown in winter and killed in the spring, so the dead stalks can be flattened over soybean and vegetable fields to block sunlight and prevent spring weeds from getting the light they need to germinate. ...

Ohio State Weed Specialist: Preventing the Spread of Costly Herbicide-Resistant Weed Calls for Zero Tolerance
If you see even one of this notoriously damaging weed in your field, pull it up – fast! Otherwise it could be the worst mistake you’ve ever made in your farming career, according to a researcher from Ohio State University’s College of Food, Agricultural, and Environmental Sciences. Palmer amaranth, a glyphosate-resistant weed also known to many cotton and soybean farmers in ...

In organic cover crops, more seeds means fewer weeds
Farmers cultivating organic produce often use winter cover crops to add soil organic matter, improve nutrient cycling and suppress weeds. Now these producers can optimize cover crop use by refining seeding strategies, thanks to work by an Agricultural Research Service (ARS) scientist. In moderate climates, suppressing weeds in winter cover crops is important because weeds that grow throughout ...

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 ...

Bayer CropScience and the Grains Research & Development Corporation Team up to discover Innovative Weed Control Solutions
Bayer CropScience and the Grains Research & Development Corporation (GRDC) based in Australia have signed a five-year agreement to join forces to establish the Herbicide Innovation Partnership for the discovery and development of innovative weed management solutions. The major aim is to provide growers with new technologies to manage resistant weeds and support the sustainability of modern ...

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 ...

Parasite-resistant maize developed by Kenyan scientist
Two new varieties of hybrid maize that are resistant to the deadly parasitic Striga weed have been developed by a Kenyan scientist. The weed affects cereal crops in many parts of Africa and is a major cause of crop failure in East Africa, where climate change has been driving its spread in recent years. Mathews Dida, a maize breeder in the school of agriculture and food security at Maseno ...

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 ...
