Palmer amaranth warning issued in North Dakota

The invasive weed is also really good at developing herbicide resistance

North Dakota extension personnel are warning farmers on that side of the border of the arrival of the invasive weed Palmer amaranth. The North Dakota Department of Agriculture and North Dakota State University Extension Service are advising farmers to scout new conservation plantings for Palmer amaranth, a very aggressive weed that has plagued cropland production

New herbicides help producers mix up modes of action to fight resistance

Farmers can fend off herbicide-resistant weeds and make money by changing up their weed control program

How can thinking about resistance help us economically in the short and long term?” This was a question posed by Brad Ewankiw, a project manager for FMC Canada, during a presentation on FMC’s new herbicides at North Star Genetics’ annual soybean grower information day in Morris March 27. Ewankiw pointed to pre-emergent residual herbicides as

Kochia: ‘the cockroach of the plant world’

Weed can duplicate extra copies of a gene 
which is resistant to glyphosate

A Kansas State University weed scientist says he’s figured out why glyphosate-resistant kochia is like a “cockroach of the plant world.” Mithila Jugulam, assistant professor of agronomy, led a study that looked at how kochia evolved resistance to the herbicide. The researchers found that kochia has evolved to have multiple copies of a gene code
