Unraveling the Role of P450 Reductase in Herbicide Metabolic Resistance Mechanism

Plant Direct
Plants require cytochrome P450 reductase (CPR) to supply two electrons for cytochrome P450 monooxygenase enzymes (P450) to react with an organic substrate.

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

A Case of One Step Forward and Two Steps Back? An Examination of Herbicide-Resistant Weed Management Using a Simple Agroecosystem Dynamics Model

Systems
Global herbicide-resistant weed populations continue rising due to selection pressures exerted by herbicides. Despite this, herbicides continue to be farmers’ preferred weed-control method due to cost and efficiency relative to physical or biological ...

The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

Pest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Management of herbicide-resistant weed beet: a simulation study [PDF]

, 2008
In regions of sugar beet cultivation, weed beet infestations are responsible for economic losses. Weed beet belongs to the same species as the cropped plant, thus rendering herbicide control impossible in conventional sugar beet where costly practices such as manual weeding of bolters must be carried out instead. Genetically-modified herbicide-tolerant

From knowledge to action: the importance of characterizing herbicide resistance mechanisms for implementing management strategies

Pest Management Science, EarlyView.
This review bridges the gap between understanding resistance mechanisms and applying them in weed management, highlighting how mechanistic insights reveal vulnerabilities that can guide more effective control strategies. Abstract Herbicide resistance remains one of the most intensively studied areas in weed science because of its direct consequences ...

Innovation in pest management: can the past inform the future?

Pest Management Science, EarlyView.
Progress in pest management occurred incrementally, but occasionally, transformative discoveries introduced disruptive technologies. Looking ahead, generative artificial intelligence is expected to accelerate agricultural discovery by integrating vast datasets from mechanization, genetics, and chemistry.
