Dow AgroSciences Australia Ltd has developed a genetically modified (GM) soybean line known as DAS-68416-4 that is tolerant to two herbicides, glufosinate ammonium and 2,4-dichlorophenoxyacetic acid (2,4-D). Tolerance to glufosinate ammonium is achieved through expression of the enzyme phosphinothricin acetyl transferase (PAT) encoded by the pat gene derived from the soil bacterium Streptomyces...

Glufosinate applications at midnight showed reduced barnyardgrass control compared to applications made at noon and 6 P.M. Early morning applications at 6 A.M. also showed reduced barnyardgrass efficacy compared to applications at 6 P.M. Environmental factors such as temperature and light conditions at the time of application are likely responsible for the time of day effects observed in this s...

68 Abstract Transgenic bromoxynil-, glufosinate-, and glyphosate-resistant crops have been commercialized and grown extensively in the Western Hemisphere and, to a lesser extent, elsewhere. Bromoxynil-resistant crops have been removed from the market. Few new herbicide-resistant crops (HRCs) are likely to be introduced in the near future. Glyphosate-resistant cotton and soybean have become domi...

The occurrence of transgenic herbicide-resistant oilseed rape (Brassica napus) in ruderal (non-crop disturbed) areas has not been investigated previously in Canada. The primary objective of this study was to document their occurrence in two main ruderal areas (along railways and roads) in the province of Saskatchewan, where half of all oilseed rape is grown, and at the port of Vancouver, Britis...

Tomato (Solanum lycopersicum) is a model organism for Solanaceae in both molecular and agronomic research. This project utilized Agrobacterium tumefaciens transformation and the transposon-tagging construct Activator (Ac)/Dissociator (Ds)-ATag-Bar_gosGFP to produce activation-tagged and knockout mutants in the processing tomato cultivar M82. The construct carried hygromycin resistance (hyg), gr...

Abstract The development of glufosinate-resistant soybean cultivars has created opportunities for use glufosinate applied postemergence weed control. Four field experiments were conducted in 2021 and 2022 to ascertain the effect rate addition ammonium sulfate on annual control glyphosate/glufosinate/2,4-D–resistant soybean. An increased 500 from 300 g ai ha −1 improved common ragweed, lambsquar...

Abstract A comprehensive, Wisconsin state-wide assessment of waterhemp response to a diverse group herbicide sites action has not been conducted. Our objective was characterize the collection accessions postemergence (POST) and preemergence (PRE) herbicides commonly used in corn soybean Wisconsin. Greenhouse experiments were conducted with more than 80 from 27 counties. POST treatments included...
