Resistance to protoporphyrinogen oxidase inhibitor herbicides in giant ragweed (Ambrosia trifida) is associated with a novel R98Q target-site mutation in PPO2
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.
BACKGROUND In 2023, soybean growers in Eaton County, Michigan, reported repeated failures to control common ragweed (Ambrosia artemisiifolia L.) with (PPO)-inhibiting herbicides, sulfentrazone and fomesafen, in non-genetically modified soybeans. This study aimed to investigate resistance levels and mechanisms of resist...

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...

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...

In this study, pyridaben LC values, resistance ratios, detoxification enzyme activities, synergism tests, and the H92R target-site mutation were investigated in T. urticae populations collected from apple orchards, providing important insights into the biochemical and molecular mechanisms underlying pyridaben resistanc...

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.

BACKGROUND
The South American tomato pinworm, Phthorimaea absoluta, has developed resistance to diamide insecticides mainly through target-site mutations in the ryanodine receptor (RyR), including I4746M, G4903E, and G4903V. Recently, a novel mutation, I4746K, has been identified in field populations of P. absoluta, bu...
