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.

Interaction of pre- and post-emergence herbicide treatment on efficacy of different black-grass biotypes with enhanced metabolism [PDF]

, 2014
In an outdoor container trial with different resistant black-grass biotypes with enhanced metabolism, efficacy of pre- and post-emergence treatments as well as their sequence was investigated in spring wheat.

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 ...

Efficient Nitrogen Management for Reducing Weed Population and Improving Productivity of Boro Rice

Fundamental and Applied Agriculture
Among many causes of weed growth and rice's low yield, improper nitrogen management are thought to be an important issue. An experiment was conducted from December 2021 to June 2022 at the Agronomy Field Laboratory, Bangladesh Agricultural ...

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 ...

Economic evaluation of a weed-activated sprayer for herbicide application to patchy weed populations [PDF]

Spatial distribution of weeds in a crop is patchy. Traditional boom sprayers waste herbicide by applying it to areas where weed density is already low.

Selectivity of pre-and post-emergence herbicides to very-early maturing soybean cultivars [PDF]

, 2018
The combination of pre- and post-emergence herbicides may affect their selectivity to soybean plants, especially to short-cycle cultivars. The objective of this work was to evaluate the selectivity of pre- and post-emergence herbicides to very-early ...

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 ...

Persistence of PPO mutations and dynamics of Amaranthus palmeri resistance to PPO-inhibitor herbicides in a decade. [PDF]

Pest Manag Sci
Over a decade, Arkansas Amaranthus palmeri populations maintained resistance to PPO‐inhibiting herbicides. PPO2 mutations relate to shifts in herbicide resistance patterns over time. Abstract BACKGROUND Amaranthus is a highly troublesome weed genera globally.
