Role of absorption and translocation in the mechanism of glyphosate resistance in horseweed (Conyza canadensis)

Weed Science, 2005
Abstract Greenhouse and laboratory experiments were conducted to investigate mechanisms of glyphosate resistance in horseweed populations from Mississippi, Arkansas, Delaware, and Tennessee. A nondestructive leaf-dip bioassay was developed to confirm resistance and susceptibility in individual test plants. A single leaf was excised from each plant, and

Influence of formulation and glyphosate salt on absorption and translocation in three annual weeds

Weed Science, 2005
Abstract Absorption and translocation of three commercial formulations of glyphosate, the isopropylamine salt formulated as Roundup Ultra™ (IPA1) and Roundup UltraMax™ (IPA2) and the diammonium salt formulated as Touchdown™ IQ (DA), were compared in three- to five-leaf velvetleaf, common waterhemp, and pitted morningglory.

Uptake, translocation, metabolism and selectivity of glyphosate in Canada thistle and leafy spurge

Weed Research, 1976
Summary:The uptake, translocation and metabolism of glyphosate [N‐(phosphonomethyl) glycine] by Canada thistle (Cirsium arvense (L.) Scop.) (susceptible) and leafy spurge (Euphorbia esula (L.)) (resistant) were examined in an attempt to elucidate the nature of the differential sensitivity.

Comparison of efficacy, absorption and translocation of three glyphosate formulations on velvetleaf ( Abutilon theophrasti )

Pest Management Science, 2006
Abstract Growth analysis, absorption and translocation studies were conducted to compare a 1‐aminomethanamide dihydrogen tetraoxosulfate (GLY‐A) formulation of glyphosate with two isopropylamine (GLY‐IPA‐1, GLY‐IPA‐2) formulations of glyphosate on velvetleaf.

Translocation of Glyphosate, Quizalofop, and Sucrose in Quackgrass (Elytrigia repens) Biotypes

Weed Science, 1993
The translocation pattern and distribution in rhizomes of14C-glyphosate,14C-quizalofop, and14C-sucrose was examined in five quackgrass biotypes. Translocation of radioactivity in the different plant parts varied among biotypes. Translocation in the whole plant after treatment with the three14C-chemicals varied among biotypes but was not correlated with
