Abstract Recent reports indicate that manganese (Mn), applied as a foliar fertilizer in tank mixtures with glyphosate, has the potential to antagonize glyphosate efficacy and reduce weed control. It was hypothesized that Mn2+ complexed with glyphosate in a similar manner to Ca2+, forming salts that were not readily absorbed and, thereby, reducing ...

Black nightshade was subjected to two degrees of water stress by adding polyethylene glycol 20,000 (PEG) to the nutrient solution 5 d before treatment with glyphosate. The ED50values for glyphosate, determined from dose-response curves, demonstrated that both degrees of water stress strongly increased the ED50, with and without the surfactant Ethomeen ...

Abstract The influence of herbicide placement and plant growth stage on the absorption and translocation patterns of 14C-glyphosate in glyphosate-resistant cotton was investigated. Plants at four growth stages were treated with 14C-glyphosate on a 5-cm2 section of the stem, which simulated a postemergence-directed spray (PDS) application, or on the ...

EFFECTS OF GROWTH STAGE ON TRANSLOCATION OF GLYPHOSATE IN QUACK GRASS
Canadian Journal of Plant Science, 1974Visual symptoms of toxicity (inhibition of leaf growth and bud germination) were used to study the influence of growth stage of quack grass (Agropyron repens (L.) Beauv.) on glyphosate (N-phosphonomethyl glycine) transport and efficiency. Glyphosate (or a toxic metabolite) moved in sufficient quantity from the point of application on the leaf within 1

Role of Translocation as A Mechanism of Resistance to Glyphosate
Weed Science, 2009The continuous use of glyphosate has resulted in the selection of glyphosate-resistant (GR) biotypes in 13 weed species. Decreased translocation of glyphosate to the meristematic tissue is the primary mechanism of resistance in horseweed, hairy fleabane, rigid ryegrass, and Italian ryegrass, and the resistance is inherited as a single, semidominant ...

Effects of Frost and Maturity on Glyphosate Phytotoxicity, Uptake, and Translocation
Weed Science, 1979The effect of temperatures below 0 C and plant maturity on the phytotoxicity of glyphosate [N-(phosphonomethyl)glycine] on rapidly growing alfalfa (Medicago sativaL. ‘Vernal’) and quackgrass [Agropyron repens(L.) Beauv.] plants was studied in a controlled environment.

Absorption and Translocation of Fluridone and Glyphosate in Submersed Vascular Plants
Weed Science, 1981The uptake and translocation of fluridone {1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenyl]-4(1H)-pyridinone} were examined in sago pondweed (Potamogeton pectinatusL.) and Richardson pondweed [Potamogeton richardsonii(Ar. Benn.) Rydb.]. Root and shoot tissues of both species were isolated from each other with wax barriers and treated individually with 1.
