Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

Pest Management Science, EarlyView.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies

Pest Management Science, EarlyView.
Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

Peanut Response to Soil and Foliar Applications of Imazapyr

Peanut Science
Georgia leads the nation in both pine tree (Pinus spp.) timber volume and peanut (Arachis hypogaea L.) ha harvested annually. Off-target movement of pine forest herbicides into peanut fields can occur from aerial applications. Research was conducted from 2020-2022 in Ty Ty, Georgia to determine peanut response to imazapyr from preemergence (PRE) and ...

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.

Geomorphic Responses to Post‐Grazing Recovery and Stream Restoration in Semiarid Grassland Streams

River Research and Applications, EarlyView.
ABSTRACT Semiarid grassland streams are sensitive to land use, climate, extreme discharges, and internal geomorphic thresholds that drive episodic erosion. Rooted in a process‐based philosophy and commonly applied to historically wood‐rich, beaver‐modified systems, low‐tech process‐based restoration using structures is increasingly being extended to ...

Using phenology to improve invasive plant detection in fine‐scale hyperspectral drone‐based images

Remote Sensing in Ecology and Conservation, EarlyView.
Using drone‐based hyperspectral images of mixed temperate successional forests collected over a growing season, detection algorithms were produced for three invasive species of interest, which are not only invasive in Virginia but also much of the U.S.: Ailanthus altissima (tree of heaven), Elaeagnus umbellata (autumn olive), and Rhamnus davurica ...

Scale dependence in remotely sensed biodiversity: Leveraging continental‐scale imaging spectroscopy from the National Ecological Observatory Network

Remote Sensing in Ecology and Conservation, EarlyView.
Imaging spectroscopy enables large‐scale biodiversity assessment, yet spectral diversity metrics are scale dependent. Across 15 NEON ecosystems, we find that spectral richness increases sub‐linearly from 3600 m2 to 4 km2, whereas spectral divergence shows weak or inconsistent scaling with area, underscoring the importance of scale‐aware interpretation ...
