Abstract A population of common ragweed from Delaware was not controlled in the field by herbicides that inhibit acetolactate synthase (ALS) or protoporphyrinogen oxidase (PPO). Research was conducted to ascertain if this population was resistant to these herbicidal modes of action and, if so, to determine the resistance mechanism(s). Resistance was confirmed by dose-response studies on greenhouse-grown plants with multiple ALS- and PPO-inhibiting herbicides. DNA sequence data revealed that… 

INHERITANCE OF RESISTANCE TO PROTOPORPHYRINOGEN OXIDASE INHIBITOR HERBICIDES IN WILD POINSETTIA

Weed resistance to herbicides is a major global problem for agriculture. In recent years, the increased use of herbicides, without proper planning, has led to a large increase in the number of cases

Inheritance of fomesafen and imazethapyr resistance in a multiple herbicide‐resistant Euphorbia heterophylla population

TLDR
The lack of difference in herbicide response between the F₁ family and the R parental biotype was taken as evidence for completely dominant resistance to imazethapyr and fomesafen.

Triallate-resistant wild oat (Avena fatua L.): unexpected resistance to pyroxasulfone and sulfentrazone

TLDR
Results indicate previously selected resistance to ACCase and ALS inhibitors or triallate could limit the utility of new herbicide modes of action for control of wild oat.

Survey of imazethapyr-resistant common ragweed (Ambrosia artemisiifolia L.) in Quebec

TLDR
The results confirm the presence of multiple populations of imazethapyr-resistant common ragweed in Quebec.

A high diversity of mechanisms endows ALS-inhibiting herbicide resistance in the invasive common ragweed (Ambrosia artemisiifolia L.)

TLDR
This study provides novel data on ragweed resistance to herbicides, and emphasises that local resistance management is as important as mitigating gene flow from populations where resistance has arisen, and reveals an unsuspected diversity of ALS alleles underlying resistance.

Multiple Resistance Evolution in Bipyridylium-Resistant Epilobium ciliatum After Recurrent Selection

TLDR
Epilobium ciliatum from Chilean olive orchards had resistance to only two MAOs, but resistance to five MOAs could occur in the next cropping seasons, if alternatives to weed management, other than herbicides, are not included.

Nontarget site resistance in Palmer amaranth [Amaranthus palmeri (S.) Wats.] confers cross-resistance to protoporphyrinogen oxidase-inhibiting herbicides

TLDR
Evaluated the cross- and multiple-resistance profile of the RCA accession and revealed a lower level of RCA resistance when compared with fomesafen alone, shedding light on the relative unpredictability of NTSR in conferring herbicide cross-and multiple resistance in Palmer amaranth.

PPO2 Mutations in Amaranthus palmeri: Implications on Cross-Resistance

TLDR
Evaluated the response of PPO-resistant A. palmeri accessions, harboring the ppo2 mutations ΔG210 and G399A, to multiple P PO-inhibiting herbicides and found populations with a high frequency of ΔG 210-homozygous survivors exhibited high potential for cross-resistance to other PPO herbicides.

Investigation of resistance mechanism to fomesafen in Amaranthus retroflexus L.

Multiple Resistance to PPO and ALS Inhibitors in Redroot Pigweed (Amaranthus retroflexus)

TLDR
This study confirms the first case of multiple resistance to PPO and ALS inhibitors in A. retroflexus and determines that the target-site resistance mechanism was produced by Ala-205-Val and Arg-128-Gly mutations in the ALS gene and PPX2 gene, respectively.

Response of ALS-Resistant Common Ragweed (Ambrosia artemisiifolia) and Giant Ragweed (Ambrosia trifida) to ALS-Inhibiting and Alternative Herbicides1

TLDR
Results of these studies confirmed the presence of ALS–cross-resistant populations of common and giant ragweed in Ohio and suggest that herbicides with different mechanisms of action will be required to manage these weeds effectively.

A common ragweed population resistant to cloransulam-methyl

TLDR
A population of common ragweed not controlled by an acetolactate synthase (ALS)-inhibiting herbicide was sampled near Dunkirk, IN, the first year of the herbicide's commercialization in 1998, and an inferred leucine for tryptophan substitution at amino acid position 574 in ALS was responsible for the observed herbicide resistance.

Wide Distribution of the Waterhemp (Amaranthus tuberculatus) &Dgr;G210 PPX2 Mutation, which Confers Resistance to PPO-Inhibiting Herbicides

TLDR
Direct evidence in support of the hypothesis that the populations of Illinois, Kansas, and Missouri contained the same resistance mechanism was provided by DNA sequencing, which showed that nearly all resistant plants evaluated contained the &Dgr;G210 mutation.

Association of the W574L ALS substitution with resistance to cloransulam and imazamox in common ragweed (Ambrosia artemisiifolia)

TLDR
It is concluded that a Leu574 allele is the predominant basis for cloransulam resistance in common ragweed; however, other mechanisms of resistance to ALS inhibitors exist in some populations.

A codon deletion confers resistance to herbicides inhibiting protoporphyrinogen oxidase

TLDR
Unique aspects of the resistance mechanism include an amino acid deletion, rather than a substitution, and the dual-targeting nature of the gene, which may explain why resistance to PPO inhibitors has been rare.

Resistance of weeds to ALS-inhibiting herbicides: what have we learned?

TLDR
Resistance to ALS-inhibiting herbicides has greatly affected weed science by influencing how the authors view the sustainability of their weed management practices, what they consider when developing and marketing new herbicides, and how they train new weed scientists.

Common Ragweed (Ambrosia artemisiifolia) Interference in Soybeans (Glycine max)

TLDR
Soybean yield was not reduced by a natural population of common ragweed if the period of interference was limited to 6 weeks or less after crop emergence, and the weed canopy intercepted 24% of the photosynthetically active radiation.

Influence of Common Ragweed (Ambrosia artemisiifolia) Time of Emergence and Density on White Bean (Phaseolus vulgaris)

TLDR
Time of ragweed emergence may be more important than weed density when evaluating weed control options when evaluating Weed control options.

High outcrossing in the annual colonizing species Ambrosia artemisiifolia (Asteraceae).

TLDR
Observations of pollen-tube growth and seed set following controlled pollinations demonstrated that plants of A. artemisiifolia possess a strong self-incompatibility mechanism, contrary to earlier reports and assumptions.

Agriculture: The selector of improbable mutations

TLDR
It is conceivable to obtain herbicide resistance due to a single nucleotide substitution, and naturally occurring mutations with internal deleted amino acids have not been reported, which is in a range where the odds for such mutations in any mammalian species are almost nil.
