The objective of the study was to compare Vida (pyraflufen) with various tank mix partners for glyphosate-resistant kochia control. Flixweed control complete in fallow all herbicides by 28 days after treatment. Kochia best when applied glyphosate and Spartan. However, due part extremely dry conditions, no treatment controlled more than 83% at treatment, began decline this DAT.

In 1985–2002 thirteen weeds resistant to atrazine were selected by a repeated application of triazine herbicides on arable land, in orchards, non-agricultural land and at railways in the Czech Republic. Recently Digitaria sanguinalis biotypes resistant to atrazine have been found at three railway junctions. Long-lasting application of the active ingredient imazapyr at railways caused selection ...

A possible influence of low growth temperature on the photochemical activity of isolated mesophyll chloroplasts was studied in three biotypes of kochia [Kochia scoparia (L.) Schrad.] that showed either double resistance to both atrazine and acetolactate synthase (ALS) inhibitors (Bubny biotype), resistance to ALS inhibitors but not to atrazine (Jihlava biotype), or sensitivity to both types of ...

Multiple herbicide-resistant kochia [ Bassia scoparia (L.) A.J. Scott] is a growing weed management concern for farmers in the Canadian prairies. A randomized–stratified survey of 319 sites Alberta was conducted 2021 to determine frequency and incidence glyphosate, fluroxypyr, dicamba resistance samples four nine years after previous rounds surveys. Kochia exhibiting were found at 78%, 44%, 28%...

Field, greenhouse, and laboratory experiments were conducted at the Montana State University Southern Agricultural Research Center, Huntley, MT, USA, in 2012 and 2013, to evaluate the effectiveness of various postharvest-appliedherbicideson late-season control, fecundity, seed viability, andprogenyfitnessofKochia scoparia (kochia) in wheat stubble. Paraquat þ atrazine, paraquat þ linuron, and p...
