Glyphosate‐resistant Lolium multiflorum in Chilean orchards
Abstract: Lolium multiflorum (Italian ryegrass) seeds suspected of being resistant to glyphosate were collected from fruit orchards at two locations, San Bernardo (SB) and Olivar (OL), Chile, that had been treated an average of three times per year with the isopropylamine salt of glyphosate during the previous 8–10 years. Laboratory experiments were conducted for each …
Role of translocation as a mechanism of resistance to glyphosate
Abstract: The continuous use of glyphosate has resulted in the selection of resistant biotypes in 13 different weed species. Three different mechanisms of resistance have been proposed for these biotypes: 1) Decreased translocation to meristems; 2) Mutation of target site 5-enol-pyruvylshikimate-3-phosphate synthase (EPSPS) and 3) Increased expression of EPSPS. Decreased translocation of glyphosate to the …
Inheritance of glyphosate resistance in Lolium perenne and hybrids with Lolium multiflorum
Abstract: Glyphosate-resistant Lolium species have been selected in weed communities where glyphosate is the herbicide used almost exclusively for weed control. The rate of evolution of herbicide resistance is highly influenced by the mating system and the inheritance type. Given the relevance of Lolium spp. as major weeds of winter cereal crops, it is important …
