  • 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 ...

  • 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 ...

  • Weed Science Society of America Says Flooding Along Our Nation’s Rivers Worsened by Invasive Weeds

    This year flooding has ravaged thousands of homes and businesses in communities across the U.S. And scientists say the prevalence of invasive weeds is one of the factors that may be contributing to the damage. These foreign invaders are overrunning many vital “riparian” lands – the ecologically diverse natural habitats that run along the millions of miles of our nation’s waterways and help to ...

  • 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 ...

  • New joint initiative to combat metabolic resistant ryegrass

    On the heels of its A$45 million partnership with the Grains Research and Development Corporation (GRDC) to develop weed control solutions for farmers, Bayer CropScience has announced it is joining forces with The University of Western Australia (UWA) to combat herbicide resistant annual ryegrass. Together with funding from the Australian Research Council, the three-year, A$1.1 million initiative ...

  • Sandwich system found effective in organic apple orchards

    In organic apple orchards, one of the most serious challenges for growers is determining ways to limit weed competition while improving soil quality and ensuring high yields of quality apples. Scientists from the Swedish University of Agricultural Sciences published a study of orchard floor management systems (HortScience, March 2015) that revealed the benefits of using "sandwich systems" in ...

  • Farm machinery and sustainable agriculture must evolve together

    Farm machines have revolutionized agriculture and reduced drudgery for millions of farm families and workers, but the machinery of tomorrow will have to do more than that – it will also have to contribute to agriculture that is environmentally sustainable. A new FAO book Mechanization for rural development, a review of patterns and progress from around ...

  • Organic farming profitable long-term

    Organic farming is known to be environmentally sustainable, but can it be economically sustainable, as well? The answer is yes, according to new research in the Sept.-Oct. issue of the Agronomy Journal. In an analysis of 18 years of crop yield and farm management data from a long-term University of Minnesota trial, an organic crop rotation was consistently more profitable and carried less risk of ...

  • North Florida farmers are using sesame as a rotation crop

    In between seasons of corn, peanut, and cotton, North Florida farmers were interested in growing a rotation crop that could withstand the wilting heat of summer and be harvested by machine. So, since 2011, University of Florida researchers have been experimenting with growing the tiny seeds you find on top of hamburger buns or garnishing salads – sesame – as a viable, money-making ...

  • Disruptive changes coming in technologies of food production, finds report

    Changes in the way food is grown will soon represent risk to existing dominant players worldwide and create new opportunities in agriculture, a new report finds. Increasing population, climate change, rising fossil fuel prices, ecosystem degradation and water and land scarcity are making today's food production methods increasingly unsustainable and driving important new innovation in ...

  • Hops Conference to Feature New Harvester, Prototype Trellis System

    The hops industry is booming in Ohio, and organizers of The Ohio State University Hops Conference and Trade Show on Feb. 24-25 have brewed up a program that will keep the learning flowing for beginner and advanced growers alike. “There was an estimated 200 acres of hops planted in Ohio on 80 farms in 2016, up from 10 acres on four farms in 2014,” said Brad Bergefurd, horticulture ...

  • Scientists find four-leaf clover gene

    Ending a period of “bad luck” for clover researchers, scientists report finding the gene that turns ordinary three-leaf clovers into the coveted four-leaf types. Masked by the three-leaf gene and strongly influenced by environmental condition, molecular markers now make it possible to detect the presence of the gene for four-leaves and for breeders to work with it. The results of the ...

  • Health and Safety Issues in Agriculture: Is there a Way Out?

    Agriculture forms the backbone of most economies and is a chief driver of economic growth. In 2013 the agricultural sector grew by a spectacular 16.4% and aided considerably in improving the country’s ...
