GM Crops Shown to Decrease Damage to Environment
The increase in cultivation of herbicide-resistant GM Canola (also known as rapeseed) in Canada has led to a significant decrease in herbicide use, says research published in the journal Pest Management Science. This has led to a decrease in the environmental impact of weed control and could have... view more (2004-10-20)
New Effects Of Herbicides On Plants
The aim of Navarre engineer Ana Zabalza Azn'¡rez's PhD thesis - entitled "The inhibition of the biosynthesis of amino acids in ramified chain and their use as a target-site for herbicides" - was to find out what effects herbicides produce on the metabolism of plants so as to enable a more... view more (2004-01-22)
GM CROPS AND THE ENVIRONMENT
The Natural Environment Research Council (NERC), as well as other research bodies, is investigating possible impacts of GMOs on the environment. For some crops and for some types of genetic modification we have a clear understanding of the risks. For others, further work is needed to reduce... view more (1999-02-22)
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. view more (2008-04-23)
How Are Herbicides Discovered?
A new interactive web lesson teaches upper-level undergraduate students and graduate students how herbicides are developed. view more (2008-09-09)
Chemically-conscious gardeners use bugs to beat back the weeds â€" Microbiology Today: May 2005 issue
Organic gardeners can control pesky weeds with the help of some common soil microbes, according to an article in the May 2005 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology. view more (2005-04-26)
Why does an anti-anthrax drug kill plants too?
Scientists at the John Innes Centre (JIC), Norwich (1) have today reported that a very successful antibiotic, which is harmless to humans but lethal to most bacteria, also kills plants. They have found that an enzyme, which is an important target for several families of antibiotics and was thought... view more (2004-05-12)
Keeping yields, profits and water quality high
One of the key questions facing agriculturalists in the 21st century is how to produce adequate amounts of food and farm income while protecting environmental quality. view more (2008-05-08)
A new portable biosensor detects traces of contaminants in food more quickly and cheaply
Scientists at the Universitat Autonoma de Barcelona (UAB), in cooperation with the CSIC, have developed a new electro-chemical biosensor which detects the presence, in food, of very small amounts of atrazine -one of the most widely used herbicides in agriculture and which also has very long lasting... view more (2007-05-18)
Cornell researchers identify natural herbicide that controls weeds around some common lawn grasses
Certain varieties of common fescue lawn grass come equipped with their own natural broad-spectrum herbicide that inhibits the growth of weeds and other plants around them. view more (2007-11-09)
Can we keep the cap on transgene escape?
Molecular strategies are being developed to impede the escape of transgenes from transgenic crops into wild relatives, which might become invasive upon acquiring transgenic traits such as resistance to pests or herbicides. For example, to impede escape through pollen, a transgene could be inserted... view more (2004-02-24)
New hope for horse lovers as effective control for killer ragwort is proposed
Scientists propose developing an environmentally-friendly fungal spray that would specifically target Ragwort, infecting and killing the weed at a critical growth stage. view more (2007-10-11)
Long-term pesticide exposure may increase risk of diabetes
Licensed pesticide applicators who used chlorinated pesticides on more than 100 days in their lifetime were at greater risk of diabetes, according to researchers from the National Institutes of Health (NIH). view more (2008-06-05)
The ecological production of cereal crops is more profitable
The growing of cereal crops without recourse to fertiliser application or weeding, but alternatively rotating with vetch and fallow, together with returning the straw to the soil after the harvest, increases the production yield two-fold with respect to the conventional mode of growing crops, with... view more (2004-02-13)
Insects see crops clearly when the weeds have gone
All gardeners know that their plants have to compete against insects and weeds. We apply insecticides to protect plants from the munching hordes, and we apply herbicides, or hoe, to protect plants from weeds. But, according to Stan Finch and Rosemary Collier of Horticulture Research International,... view more (2003-06-05)
Sentry enzyme blocks two paths to Parkinson's disease
The degeneration of brain cells that occurs in Parkinson's disease may be caused by either externally provoked cell death or internally initiated suicide when the molecule that normally prevents these fatal alternatives is missing. view more (2007-02-02)
GM crops should now be banned
Government advisors have today confirmed that GM herbicide tolerant (HT) crops could harm wildlife, including farmland birds. The Advisory Committee on Releases to the Environment (ACRE) has warned that GMHT beet and spring-sown oilseed rape will reduce seed numbers because weeds will be destroyed.... view more (2004-01-13)
Study concludes that pesticide use increases risk of Parkinson's in men
Mayo Clinic researchers have found that using pesticides for farming or other purposes increases the risk of developing Parkinson's disease for men. view more (2006-06-15)
New study suggests link between environmental toxins and early onset puberty in girls
Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls. view more (2008-02-07)
Scientists ramp up ability of poplar plants to disarm toxic pollutants
Scientists since the early '90s have seen the potential for cleaning up contaminated sites by growing plants able to take up nasty groundwater pollutants through their roots. Then the plants break certain kinds of pollutants into harmless byproducts that the plants either incorporate into their... view more (2007-10-16)
Disrupting common parasites' ability to 'talk' to each other reduces infection
One of the most common human parasites, Toxoplasma gondii, uses a hormone lifted from the plant world to decide when to increase its numbers and when to remain dormant, researchers at Washington University School of Medicine in St. Louis have found. view more (2008-01-10)
Genetic engineering of plants: nature was first
Queen Mary and Westfield College scientists studying resistance to infection in plants have discovered by chance that a natural form of genetic engineering has already brought foreign genes into their genetic make-up. view more (1998-09-01)
Scientists in first global study of 'poison' gas in the atmosphere
It was used as a chemical weapon in the trenches in the First World War, but nearly a century later, new research by an international team of scientists has discovered that phosgene is present in significant quantities in the atmosphere. view more (2007-09-20)
Family study bolsters link between pesticides and Parkinson's
For the first time, the association between Parkinson's disease and exposure to pesticides has been shown in patients with the neurological disorder compared with their unaffected relatives, according to a study in the online open access journal BMC Neurology. view more (2008-03-28)
Mustard seed meal suppresses weeds in container-grown ornamentals
Mustard is one of the most widely used condiments on the planet. Prized for its oils, mustard plants grow wild in North Africa, the Middle East, and the Mediterranean, and is grown commercially in the United Kingdom, Canada, and the United States. view more (2008-09-30)
