Stability studies of cynaropicrin–major sesquiterpene lactone of Cynara cardunculus leaves

Pest Management Science, EarlyView.
This study investigated its stability under high temperature and pH, mimicking agronomic extremes and under soil context. Bioassays demonstrated that degradation products exhibited higher phytotoxic activity than cynaropicrin and deacylcynaropicrin. This is the first study about cynaropicrin's stability, characterizing degradation products, and their ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...
