Abstract Aminopyralid is a new auxinic herbicide that provides Canada thistle control at lower use rates than clopyralid. Studies were conducted to determine if differences in absorption, translocation, or metabolism account for aminopyralid's greater biological activity. Radiolabeled aminopyralid and clopyralid were applied to individual leaves of rosette-stage Canada thistle plants. Nonionic surfactant was used for the absorption studies because it provided higher aminopyralid absorption than…

Absorption and Translocation of Aminocyclopyrachlor and Aminocyclopyrachlor-Methyl Ester in Canada Thistle (Cirsium arvense)
TLDR
Significantly greater aminocyclopyrachlor-methyl ester was absorbed, compared with the free acid, which was reflected in the greater aboveground translocation for the methyl ester and, based on this conversion rate, was translocated as the free acids in Canada thistle.
Absorption, Translocation, and Metabolism of Aminocyclopyrachlor in Tall Fescue (Lolium arundinaceum)
TLDR
Data suggest AMCP applied to tall fescue can remain bioavailable, and mishandling treated plant material could result in off-target injury.
Vernalization Affects Absorption and Translocation of Clopyralid and Aminopyralid in Rush Skeletonweed (Chondrilla juncea)
TLDR
Differential efficacy between fall and spring applications suggests vernalization impacts herbicide absorption and translocation in other perennial asters, and increased translocation to belowground survival structures is needed for effective control of C. juncea.
Uptake, translocation and metabolism of aminocyclopyrachlor in prickly lettuce, rush skeletonweed and yellow starthistle.
TLDR
Impaired uptake and translocation of foliar-applied aminocyclopyrachlor are dependent on active ingredient structure and species sensitivity, and highly sensitive species such as prickly lettuce absorb and translocate less material than relatively less sensitive species, such as rush skeletonweed.
Reduced Translocation Is Associated with Tolerance of Common Lambsquarters (Chenopodium album) to Glyphosate
TLDR
An important role of reduced translocation is suggested in conferring tolerance of common lambsquarters to glyphosate in an accessions from Indiana relative to a sensitive accession from Wisconsin.

To gain a better understanding of the physiology of the herbicide aminocyclopyrachlor in young plants of trumpet flower, the uptake and translocation were evaluated after the application of…
Sourgrass resistance mechanism to the herbicide glyphosate 3 Absorption and translocation of glyphosate in resistant and susceptible biotypes of Digitaria insularis
The knowledge on the mechanism that gives a weed resistance to a particular herbicide is essential regarding scientific, academic, and practical aspects because it determines the recommendations for…
Target site as the main mechanism of resistance to imazamox in a Euphorbia heterophylla biotype
TLDR
Target site mutation in the ALS gene is the principal mechanism that explains the imazamox resistance of the R biotype, but root exudation seems to also contribute to the resistance of this biotype.
Physiological Basis for Differential Selectivity of Four Grass Species to Aminocyclopyrachlor
TLDR
Research conducted to establish the tolerance of four grass species to AMCP application and observe their absorption, translocation, and metabolism indicates that tall fescue is the most tolerant of AMCP at rates required for weed control.
Clopyralid Tolerance in Strawberry and Feasibility of Early Applications in Florida
TLDR
Labeled dose clopyralid applications appear safe for application timings closer to strawberry transplant, though considerations of leaf cupping should be taken under consideration for label changes.

Canada Thistle (Cirsium Arvense) Control with Aminopyralid in Range, Pasture, and Noncrop Areas
TLDR
Aminopyralid provided effective Canada thistle control at lower use rates than current commercial standards and might be useful in areas where herbicides such as picloram and clopyralids are not recommended for use.
Clopyralid Uptake, Translocation, Metabolism, and Ethylene Induction in Picloram-Resistant Yellow Starthistle (Centaurea solstitialis L.)
TLDR
Compared between picloram-resistant and -susceptible accessions of yellow starthistle, the clopyralid-induced symptoms of ethylene production and epinasty appeared in S plants within 5 h, implying that mechanism of cross-resistance involves process(es) other than metabolism.
Absence of a role for absorption, translocation, and metabolism in differential sensitivity of hemp dogbane (Apocynum cannabinum) to two pyridine herbicides.
Hemp dogbane is sensitive to fluroxypyr and tolerant to clopyralid. Absorption, translocation, and metabolism of clopyralid and fluroxypyr were studied in hemp dogbane to determine if differences in…
Absorption and translocation of 14C-3,6-dichloropicolinic acid in Cirsium arvense (L.) Scop.
TLDR
Following application to vegetative plants, absorption and translocation of 14C-3,6-dichloropicolinic acid was rapid and was approximately doubled by high r.h, and placement of herbicide on lower leaves tended to decrease the amount of radioactivity recovered from shoot apex and increase the amount recovered from the roots.
Absorption and fate of imazapyr in leafy spurge (Euphorbia esula)
TLDR
Imazapyr phytotoxicity to leafy spurge appears to result from high imazAPyr absorption, translocation to underground meristematic areas (roots and adventitious shoot buds), and a slow rate of metabolism.
Combining Mowing and Fall-Applied Herbicides to Control Canada Thistle (Cirsium arvense)1
TLDR
Inconsistent results prohibit concluding that mowing before spraying will consistently improve Canada thistle control, and such a treatment combination should not be commonly recommended.
THE ROOT SYSTEM OF CANADA THISTLE
TLDR
The severity of infestations of Canada thistle can be predicted by determining the potential of its root system to expand and produce new shoots, and the number of root buds and the regenerative capacity of the roots varied between years.

SELECTIVE CONTROL OF CANADA THISTLE IN RAPESEED WITH 3,6-DICHLOROPICOLINIC ACID
TLDR
Control of Canada thistle topgrowth and regrowth, and tolerance of rapeseed to 3,6-dichloropicolinic acid at 0.2–0.3 kg/ha were excellent in greenhouse and field trials.
