Black-grass (Alopecurus myosuroides), one of the most economically destructive herbicide-resistant weeds in Europe, is rapidly expanding in winter wheat regions of China. In recent years, the recommended application rate of fenoxaprop-P-ethyl in the field has failed to effectively control Alopecurus myosuroides populations, thereby threatening wheat yields at risk. In this study, we collected a suspected herbicide-resistant population (R-HB) of Alopecurus myosuroides from a wheat field in Hebei Province and confirmed its resistance to fenoxaprop-P-ethyl, with a resistance index of 26.

Background: Polypogon fugax has evolved resistance to multiple herbicides in China, yet there has been no documented case of glyphosate resistance. A putative glyphosate-resistant P. fugax (HN-R) population was collected from canola fields in Hunan Province, China, surviving glyphosate treatment at the field-recommended rate [540 g acid equivalent (a.

Populations of Polypogon fugax have developed resistance to many acetyl-CoA carboxylase (ACCase)-inhibiting herbicides. This resistance threats the effectiveness and sustainability of herbicide use. In our previous research, a field P.

has become a global nuisance weed and has evolved resistance to glufosinate. The involvement of target-site resistance (TSR) in glufosinate resistance in has been elucidated, while the role of nontarget-site resistance (NTSR) remains unclear. Here, we identified a glufosinate-resistant (R) population that is highly resistant to glufosinate, with a resistance index of 13.

The excessive use of chemical herbicides has resulted in evolution of herbicide-resistant weeds. Cytochrome P450 monooxygenases (P450s) are vital detoxification enzymes for herbicide-resistant weeds. Herein, we confirmed a resistant (R) Polypogon fugax population showing resistance to quizalofop-p-ethyl, acetolactate synthase (ALS)-inhibiting herbicide pyroxsulam, and several other ACCase (acetyl-CoA carboxylase)-inhibiting herbicides.

Article Synopsis
  • Genetic engineering was used to introduce six ascovirus genes into Autographa californica nucleopolyhedrovirus (AcMNPV) to enhance its insecticidal properties by combining traits from both viruses.
  • The modified viruses, AcMNPV-111 and AcMNPV-165, showed higher viral production and insecticidal efficiency, significantly reducing the time (LT) and dose (LD) needed to impact Spodoptera exigua larvae compared to the wild-type AcMNPV-Egfp.
  • The study demonstrated that these recombinant viruses have stable virulence across different instar larvae, with recommendations for optimal infection doses to maximize the production of these enhanced baculoviruses for use as biological insect
