Long-term no-till (NT) systems in the semiarid central Great Plains of United States require flexible management strategies to minimize impacts herbicide resistant (HR) kochia (Kochia scoparia L.) and tumble windmill grass (Chloris verticillata Nutt.) as well nutrient stratification on soil crop productivity. This study examined strategic tillage (ST) control HR weeds improve yields an otherwis...

During a 36-hour period, the rate of absorption of oxygen, respiration quotient, and rate of evolution of heat have been measured using seeds of Prosopis juliflora, Kochia scoparia, and Oxyria digyna. The results obtained in pure water were compared with those obtained in dilute solutions of dinitrolphenol. The data appear to be reproducible to +/- 10% at the end of the 36-hour period and are i...

Increased adoption of crops with stacked traits conferring glyphosate and dicamba resistance, recent confirmation kochia [Bassia scoparia (L.) A.J. Scott] biotypes resistant to these herbicides in Alberta Saskatchewan, warrant surveillance herbicide-resistant Manitoba. A randomized–stratified survey 315 sites Manitoba was conducted the fall 2018. Overall, 58% populations tested were glyphosate-...

The present study investigate the effect of Kochia indica extract using Vicia faba L assay. All parameters investigated were being affected. Four concentrations of 10, 20, 30 and 40% were applied for three time duration (6, 12, 24 h). The percentage of germination and plant height are dose and time dependent, probably due to alterations in cell cycle. Treated roots were highly affected compared...

The objective of this trial was to compare Plainview, Esplanade, and Method at three applications for season-long weed control in noncropland. Glyphosate alone provided no residual control. Plainview (indaziflam/aminocyclopyrachlor/imazapyr) 64 oz/a applied the early or late fall controlled kochia similarly Krovar (bromacil/ diuron) season. Either rate as well tank mixture Esplanade (aminocyclo...
