In planta fluxapyroxad gradients from seed treatment differentially select fungicide‐sensitive and reduced‐sensitive genotypes of Pyrenophora teres f. maculata

open access: yesPest Management Science, EarlyView.
Spatial concentration gradients of seed‐applied fluxapyroxad within barley create heterogeneous exposure environments, driving differential suppression of succinate dehydrogenase inhibitor‐sensitive Pyrenophora teres f. maculata isolates and enrichment of reduced‐sensitive genotypes, thereby shaping within‐host fungicide resistance selection dynamics ...

On‐farm comparison of aerial and chemigation application methods for Striacosta albicosta (lepidoptera: Noctuidae) management in corn using pyrethroid and diamide insecticides

open access: yesPest Management Science, EarlyView.
Aerial applications deposited more insecticide on tassels than on ear level (36.4% vs. 19.8%). Across both application methods, chlorantraniliprole minimized ear injury, while bifenthrin provided moderate control. Effective management of S. albicosta requires delivering sufficient insecticide concentration to the target site and achieving adequate ...

Dispersal and aggregation patterns of Triozoida limbata (Enderlein, 1918) adults in guava orchards with multiple cultivars: implications for integrated pest management

open access: yesPest Management Science, EarlyView.
Adults of Triozoida limbata exhibit aggregated distribution patterns across different guava cultivars. Sampling with visual inspections and yellow sticky traps revealed high clustering, supporting the development of targeted integrated pest management strategies.

A rationally designed peptide targeting trypsin‐like enzymes impairs feeding and redox homeostasis in Anticarsia gemmatalis (Lepidoptera: Erebidae)

open access: yesPest Management Science, EarlyView.
GORE3 interacts with digestive proteases in Anticarsia gemmatalis, promoting digestive inhibition, oxidative stress, and midgut cell damage. These physiological disturbances diminish larval survival and feeding damage on soybean plants, emphasizing the potential of GORE3 as a bioinsecticidal peptide for pest control.

The continuing significance of chiral agrochemicals

open access: yesPest 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.

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

open access: yesResponsive 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

Bidirectional Plant‐Microneedle Responses to Guide Biomaterial Design

open access: yesSmall, EarlyView.
We examine bidirectional interactions between plants and polymeric microneedles to develop effective compound delivery strategies. Material chemistry and architecture determine stability in the plant environment, cargo–matrix interactions, and the magnitude and duration of the plant response. Plant microneedles should therefore be designed as a coupled

Route‐Dependent Toxicity and Ecological Selectivity of Melaleuca alternifolia Essential Oil in Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...
