Characterization And Management Of Glyphosate-Resistant Junglerice, Clay M. Perkins
Characterization And Management Of Glyphosate-Resistant Junglerice, Clay M. Perkins
Doctoral Dissertations
Junglerice has become a major weed in Tennessee and across the mid-south. Glyphosate resistance and dicamba antagonism has resulted in the reported control failures and rise in prevalence. Junglerice was the most prevalent weed escape in cotton and soybean fields across Tennessee from 2018 to 2020. In all, 13% of the junglerice accessions could no longer be effectively controlled with glyphosate. Due to poor in-crop control, it has been recommended to start clean when trying to control junglerice and other grasses. Therefore, research was conducted to determine the best burndown methods utilizing dicamba, glufosinate, or paraquat. A sequential application of …
Effect Of Tank-Mixing Glyphosate, Dicamba, And Graminicides On Grass Weed Control In Roundup Ready 2 Xtend Soybeans, R. Liu, I. Effertz, T. Lambert, A. Jhala, V. Kumar
Effect Of Tank-Mixing Glyphosate, Dicamba, And Graminicides On Grass Weed Control In Roundup Ready 2 Xtend Soybeans, R. Liu, I. Effertz, T. Lambert, A. Jhala, V. Kumar
Kansas Agricultural Experiment Station Research Reports
The adoption of Roundup Ready 2 Xtendsoybean allows growers to use dicamba (Xtendimax or Engenia) in mixtures with glyphosate (Roundup PowerMax) or graminicides (Select Max or Assure II) for broad spectrum weed control. However, anecdotal evidence suggests that Xtendimax may cause antagonism when applied with Select Max and/or Assure II herbicides. The main objective of this study was to determine the effectiveness of Roundup PowerMax, Select Max, and/or Assure II alone or in tank-mixtures with Xtendimax for grass weed control in Xtendsoybean. Field studies were conducted in 2020 at the Kansas State University Agricultural Research Center (KSU-ARC) near Hays, KS, …
