Plants with this genetic mutation are immune to glyphosate-based herbicides such as Roundup. The Sierra Club, The Center for Food safety,
Sagers and her team found two varieties of transgenic canola in the wild one modified to be resistant to Monsantos Roundup herbicide (glyphosate),
and one resistant to Bayer Crop sciences Liberty herbicide (gluphosinate). They also found some plants that were resistant to both herbicides,
showing that the different GM plants had bred to produce a plant with a new trait that did not exist anywhere else.
By contrast, her research team found feral populations of herbicide-resistant canola growing along roads, near petrol stations and grocery stores, often at large distances from areas of agricultural production.
and tested for the presence of proteins that could give it resistance to either of the herbicides.
Of these, 80%had at least one herbicide-resistant transgene (41%were resistant to Roundup and 40%resistant to Liberty.
Feral generations Sagers says the discovery of plants that are resistant to both herbicides shows that oethese feral populations of canola have been part of the landscape for several generations.
But those that have evolved resistance to both herbicides could become a weed problem for farmers,
if you are worried about herbicide use, she says. A major advantages of herbicide-resistant crops is that non-selective herbicides can be used,

Or, if introduction of a new GM corn variety designed to be resistant to herbicide-resistant weeds can be stopped,

But herbicide resistance is a problem for farmers regardless of whether they plant GM CROPS. Some 64 weed species are resistant to the herbicide atrazine, for example,
and no crops have been modified genetically to withstand it (see The rise of superweeds). Still, glyphosate-tolerant plants could be considered victims of their own success. Farmers had used historically multiple herbicides,

Building on existing geolocation technologies, future swath control could save on seed, minerals, fertilizer and herbicides by reducing overlapping inputs.
Farmers also can use drones to tailor their use of pesticides, herbicides, fertilizer and other applications based on how much is needed at a specific point in a field a process known as precision agriculture saving the grower money from unnecessarily overusing resources

the weed-killer commonly known as Roundup or glyphosate. In the past decade as the use of this potent chemical has skyrocketed monarch populations have plummeted.
Over the past decade Roundup has become the most popular weed-killer in the country. Today's farms use it to grow Monsanto's genetically modified Roundup Ready corn

If you use weed-killer to stop grass from sprouting in your driveway it might contain glyphosate.
Glyphosate isn't a selective weed-killer it harms a lot plants. One of the plants it's wiping out is milkweed the sole source of food for monarch butterfly larvae.
The EPA could also consider requiring safety zones free of herbicides in and around farms to protect monarch-friendly habitat.
There are other herbicides which are just as harmful however so the EPA needs to ensure that whatever replaces glyphosate isn't just substituting one harm for another.
and other herbicides and encouraging a more sustainable approach to farming can help ensure that the monarchs'astonishing migration will be an event that every generation can witness.

Because the crop is resistant to the herbicide glyphosate, marketed as Roundup, farmers can spray they fields with the chemical to control weeds without risking damage to their crops.
around 94%of the soya beans and 88%of the maize (corn) grown in the United states is engineered genetically to resist herbicides, insect pests or both, according to the US Department of agriculture.

Within a month of the discovery in May, USDA scientists had traced the origin of the plants to a line of herbicide-resistant Roundup Ready wheat called MON71800,

II doubt this massive experiment will prove any better than lead paint or asbestos. Contrary to what poor old misguided Joe up there says there have been over 600 studies published over a 30 year period in numerous respected scientific journals by various experts in the relevant field in good standing.

and de-weed their fields first allowing them to bathe their lands with abundant amounts of glyphosate herbicides in the presence of corn without concern that their corn crops will be killed.
ÃÚ à The glyphosate-resistance of GMO corn has encouraged such an over-abundance of glyphosate-based herbicides to be dumped into the environment worldwide that nature has started to respond in kind with the evolution of âÂ#Âoesuperweeds.
and are forcing farmers to dump even more varieties of toxic chemical herbicides and pesticides on our foods in order to stay ahead of nature s race.
When farmers encounter plant pests their first response would be to kill it by using pesticides herbicides or antibiotics.
Yet farmers and ranchers don't often want to plunk down the money to kill them off with chemical herbicides.
#Abrasive Organic Herbicide Method Blasts Weeds To Deathone U s. Department of agriculture researcher is experimenting with a sandblasting-style method of killing weeds that could be certified organic Minneapolis'Star Tribune reports.
Biologists also introduce genes to make plants pest-and herbicide-resistant; those traits dominate the more than 430 million acres of GMO crops that have already been planted globally.
The second allows crops to tolerate the herbicide glyphosate so that farmers can spray entire fields more liberally yet kill only weeds.
But glyphosate is among the mildest herbicides available with a toxicity 25 times less than caffeine.
The herbicide kills milkweed (the larvae's only food source) in and near crops where it's applied.
