Managing the Risk of Glyphosate Resistant Weeds
Glyphosate resistant (GR) weeds have been the focus of much debate since the introduction of Roundup Ready crops in the mid 1990’s. Initially the questions focused on whether GR weeds would actually develop, but this quickly changed to how to prevent their selection following their rapid appearance after the introduction of Roundup Ready crops. Evaluating the relative effectiveness of different...
متن کاملGlyphosate inhibits rust diseases in glyphosate-resistant wheat and soybean.
Glyphosate is a broad-spectrum herbicide used for the control of weeds in glyphosate-resistant crops. Glyphosate inhibits 5-enolpyruvyl shikimate 3-phosphate synthase, a key enzyme in the synthesis of aromatic amino acids in plants, fungi, and bacteria. Studies with glyphosate-resistant wheat have shown that glyphosate provided both preventive and curative activities against Puccinia striiformi...
متن کاملGlyphosate - Resistant Crops and Weeds : Now and in the Future
The adoption of transgenic crops (also called GMOs and biotech crops) worldwide has been rapid and impressive, reaching 120 million ha in 2008, and continues to grow at a steady pace (James, 2008). Approximately 80% of the total area devoted to these crops has been planted with herbicide-resistant crops, virtually all being glyphosate-resistant (GR) crops. Thus, a single genetic trait—glyphosat...
متن کاملIsoflavone, glyphosate, and aminomethylphosphonic acid levels in seeds of glyphosate-treated, glyphosate-resistant soybean.
The estrogenic isoflavones of soybeans and their glycosides are products of the shikimate pathway, the target pathway of glyphosate. This study tested the hypothesis that nonphytotoxic levels of glyphosate and other herbicides known to affect phenolic compound biosynthesis might influence levels of these nutraceutical compounds in glyphosate-resistant soybeans. The effects of glyphosate and oth...
متن کاملPhysiological responses of glyphosate-resistant and glyphosate-sensitive soybean to aminomethylphosphonic acid, a metabolite of glyphosate.
Aminomethylphosphonic acid (AMPA) is formed in glyphosate-treated glyphosate-resistant (GR) and glyphosate-sensitive (GS) soybean [Glycine max (L.) Merr.] plants and is known to cause yellowing in soybean. Although, AMPA is less phytotoxic than glyphosate, its mode of action is different from that of glyphosate and is still unknown. Greenhouse studies were conducted at Stoneville, MS to determi...
