25 Nov Pre-seed glyphosate application had little impact on wheat rhizobacterial communities

Posted at 21:41h in Soils and Fertility

After seven years of pre-seed glyphosate application in a wheat-wheat or wheat-pea rotation, in min-till or no-till, there were few effects on the wheat rhizobacterial communities. Due to widespread adoption of no-till management and use of glyphosate-resistant transgenic crops, glyphosate is the most widely used herbicide...

30 Jun Evaluating downy and Japanese brome control

Posted at 16:56h in Weeds

Fluazifop, quizalofop, clethodim, sethoxydim, and glyphosate can all reduce downy brome and Japanese brome biomass, especially when applied shortly after germination to plants less than 4.3 inches tall —with a tendency for fluazifop and quizalofop to be most effective. Research evaluated the efficacy of glyphosate and...

31 Mar Farming without glyphosate

Posted at 17:25h in Weeds

Model predictions suggest that farming can remain profitable without glyphosate by consistently utilizing key non-herbicidal weed management practices combined with robust pre-emergence soil residual herbicide treatments. However, maintaining low weed seed banks will be challenging. The possibility of farming without glyphosate is an important issue facing...

14 Aug Triple herbicide-resistant kochia control

Posted at 17:37h in Weeds

A kochia survey in southern Alberta in 2017 found that all kochia populations were resistant to Group 2 ALS inhibitors, 50% of populations were resistant to Group 9 glyphosate, and 18% of populations resistant to Group 4 (dicamba) herbicides. Kochia populations with triple resistance to...
