Herbicide resistance in weeds [PDF]

, 2017
Resistance at the field level is best considered as 'shades of grey', with a continuum from complete susceptibility through to complete resistance. This poses a considerable challenge in detection and in assessing the severity and impact of resistance ...

The first RNAi‐based biopesticide approved in the United States: regulatory implications for the European Union – the case of Ledprona (Calantha™)

Pest Management Science, EarlyView.
The approval of the RNA interference‐based biopesticide Ledprona (Calantha™) in the USA marks a milestone for RNA‐based crop protection. We discuss the regulatory implications for the European Union, highlighting opportunities, challenges, and the need for adapted risk assessment frameworks for RNA‐based plant protection products.

Comprehensive analysis of microtubule‐inhibiting herbicides reveals shared subcellular phenotypes and distinct resistance profiles

Pest Management Science, EarlyView.
Using cellular phenotyping and resistance profiling, we show that herbicides across the Herbicide Resistance Action Committee (HRAC) Groups 3 and 23 induce indistinguishable, dose‐dependent microtubule defects. Resistance patterns, rather than cellular phenotypes, reveal distinct sites of action and support reclassifying Group 3 as α‐tubulin binders ...

Selectivity and Efficacy of Herbicides Applied in Pre-Emergence in Cassava Crop

IEEE Access
The presence of weeds at the beginning of cultivation can negatively affect cassava productivity because of the slow initial development of the crop. To minimize weed interference, pre-emergence herbicides can be used, provided they are selective to crops.

Herbicide Application Rates: Risk Premiums with Environmental Implications [PDF]

This paper examines the role of risk aversion in setting herbicide label rates and application rates. Companies establish label rates to be efficacious for a wide range of conditions.

Identifying resistance‐conferring cytochrome P450s in weeds: experimental strategies and practical considerations

Pest Management Science, EarlyView.
Identifying resistance‐conferring cytochrome P450s requires integrating weed characterization, gene discovery and functional validation. No single approach is sufficient to distinguish causal resistance genes from herbicide‐metabolizing enzymes. Abstract Cytochrome P450 monooxygenases (P450s) play a pivotal role in metabolic herbicide resistance, yet ...

Experimental evolution of herbicide resistance in chlamydomonas reinhardtii [PDF]

Our understanding of the evolutionary dynamics of selection for herbicide resistance is limited by the time and space required to conduct meaningful selection experiments in higher plants. This constrains the study of the

Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

Pest Management Science, EarlyView.
Field‐collected Ambrosia artemisiifolia populations from Michigan, USA, soybean fields exhibited strong resistance to the protoporphyrinogen IX oxidase (PPO)‐inhibiting herbicide sulfentrazone and reduced sensitivity to fomesafen. Target‐site analysis identified a novel Arg‐98‐Gln (R98Q) substitution in PPO2, co‐occurring with the previously reported ...

Effects of Glyphosate and Selective Herbicide Application Schemes on Weed Control and Species Diversity in Winter Wheat in the Zemgale Region of Latvia

Agriculture
This study aimed to compare different herbicide application schemes in winter wheat, including the application of glyphosate-containing herbicides in stubble and autumn or spring post-emergence application.

Epidemiological drivers of turnip yellows virus and its vector Myzus persicae in Australian canola (Brassica napus) systems: a 3‐year study of commercial crops and noncrop vegetation

Pest Management Science, EarlyView.
A 3‐year study across southern Australia aimed to characterize drivers of infection in the Myzus persicae–turnip yellows virus–Brassica napus pathosystem. Identification of key reservoir hosts and the strong association between earlier sowing and increased disease incidence highlight opportunities for targeted weed management, strategic sowing ...
