TL;DR

VCR and TMS have evolved resistance to lactofen and fomesafen, and VRC also exhibited reduced sensitivity to cloransulam-methyl and glyphosate, highlighting the need for integrated, diversified management to further reduce herbicide selection pressure.

Distribution of target-site resistance mechanisms to nicosulfuron and glyphosate in Amaranthus palmeri accessions from two different regions of Türkiye

Palmer amaranth (Amaranthus palmeri S. Watson) is a highly competitive weed that has evolved resistance to several modes of action and has recently become a significant problem in Türkiye. This study was designed to determine the distribution of common target-site resistance (TSR) mechanisms to the acetolactate synthas...

Novel amino acid substitutions in Protoporphyrinogen oxidase 1 endow resistance to PPO-inhibiting herbicides in Bassia scoparia

PPO-inhibiting herbicides are widely used to manage weeds in different cropping systems, yet resistance evolution threatens their long-term efficacy. Here, we investigated the molecular basis of resistance to PPO-inhibiting herbicides in Bassia scoparia biotypes collected from four locations in North Dakota, USA. Green...

Detoxification enzyme inhibitor mediated synergism of insecticide toxicity in Spodoptera frugiperda (Lepidoptera: Noctuidae)

The potential of synergists to improve insecticide efficacy and strengthen insecticide resistance management (IRM) strategies is highlighted and Cytochrome P450 monooxygenases and carboxyl esterases appear more influential in BBPL while glutathione S-transferases are more significant in BPPL.

The I4746K mutation in the ryanodine receptor is associated with high-level resistance to diamide insecticides in Phthorimaea absoluta.

The significance of the I4746K mutation in diamide resistance is emphasized and valuable insights are offered into how this mutation variably influences the binding of diamide insecticides, thereby informing strategies for resistance management in P. absoluta.
