A weed which is extremely resistant to herbicides, especially one created by the transfer of genes from genetically modified crops into wild plants. – Oxford Dictionary. This definition says a superweed is not just resistant, but extremely resistant. And not only that, but it probably became resistant after receiving a gene from a GMO

Cannabis has definitely been genetically modified for the underground and “medical” markets, but not using the modern methods that get called “GMO”. The modification of the genetics of marijuana achieved using a combination of traditional breeding techniques and clumsy, “old-school” techniques like chemical mutagenesis and induced ...

The following is an abstract from a study by weed scientist Andrew Kniss about the correlation between GMO crops and weed resistance. Genetically engineered (GE) herbicide-resistant crops have been widely adopted by farmers in the United States and other countries around the world, and these crops have caused significant changes in herbicide ...

<p>Owen has been at Iowa State University since December 1, 1982 and joined the Agronomy Department in 1986. He has directed research on a number of topics including weed seedbank population dynamics, the genetic and physiological control of weed seed dormancy, the genetics and physiology of herbicide resistance in weeds and the herbicide research / demonstration project. Owen has also been ...

Andrew's research program focuses on developing weed management programs in agronomic crops, especially sugarbeet, winter wheat, corn, and dry edible beans.</p><p>He has authored or co-authored 20 peer ...

Computer and robotic technology is helping make mechanical weed control more efficient and effective: farmers use GPS systems to guide their equipment down crop rows, and sensors can even distinguish between vegetable plants and weeds! This YouTube video describes a number of mechanical weed control methods. (The video mentions the “organic ...

<p>I am currently working as an Assistant Professor of Weed Science in the department of Agronomy at the Kansas state University Western Agricultural Research Center, Hays, KS. I have earned my Ph.D. at the Montana State University-Bozeman in plant science with major focus on weed science. Prior to my position at KSU, I also worked as Postdoc in weed science program at the Montana State ...

The following is an excerpt of an article by CropLife International entitled, "Managing Weed Resistance." Like bacteria with antibiotics, weeds naturally develop resistance to herbicides over time. In fact, about 250 weed species have evolved to resist 160 different herbicides, according to the International Survey of Herbicide-Resistant Weeds.

Q: What is GMO weed? Now that you are patenting it, are yo u fighting for its legalization? Does Monsanto approve or condone the use of marijuana? And why is GMO marijuana considered acceptable, while organic marijuana is not? Answered By Cathleen Enright - Aug 22, 2013. A: We don’t know of any legitimate GM Marijuana in development or in ...

Herbicide cost per acre depends on a wide number of variables including (but not limited to) weed species present, farm location, timing of application, crop seeding rate, competitiveness of crop, herbicides used, length of growing season in that location, etc.</p> <p>Thinking about herbicide cost is only one of many factors to consider regarding input cost as well as revenue expectations.
