Pea-root exudates and their effect upon root-nodule bacteria

, 1972
The main purpose of this investigation was to study the exudation (mechanism, sites) of various compounds by roots of pea seedlings in relation to the growth of Rhizobium leguminosarum.Chapter 1 gives a survey of the literature pertaining to plant-root ...

Identification of broadly expressed nervous system‐related genes as effective RNAi targets in the brown marmorated stink bug, Halyomorpha halys

Pest Management Science, EarlyView.
Broadly expressed genes outperformed brain‐enriched neural targets as RNAi candidates in Halyomorpha halys. Microinjection of dsRNA targeting alpha‐soluble NSF attachment protein (Asnap) or Ras opposite protein (Rop) caused strong feeding suppression and near‐complete mortality, identifying them as promising targets for future oral or spray‐based RNAi ...

Phosphite concentration: its effect on phytotoxicity symptoms and colonisation by Phytophthora cinnamomi in three understorey species of Eucalyptus marginata forest

, 2000
Pre-treatment of plants with foliar sprays of 0.2, 0.5 and 2% phosphite restricted colonisation by Phytophthora cinnamomi in inoculated stems of Adenanthos barbiger and Daviesia decurrens, and led to a reduction in the isolation of P.

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 ...

Endophytic bacterium Sphingomonas panaciterrae NB5 influences soil properties and improves growth, nutrient contents, and yield of red amaranth (Amaranthus tricolor L.)

Current Plant Biology
Plant growth promoting rhizobacteria (PGPR) are crucial for enhancing plant growth and restoring soil health. Despite the excellent plant growth promoting traits, information is limited on the efficacy of Sphingomonas as a PGPR, especially in vegetable ...

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.

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 ...
