Post-emergent herbicidal activity of cineole derivatives [PDF]

open access: yes, 2014
Essential oils are being investigated as potential herbicides or to provide leads to new environmentally and socially acceptable herbicides. Novel hydroxy and ester derivatives of 1,8-cineole and 1,4-cineole were synthesised, by chemical and biological ...

Biocontrol and plant growth‐promoting potential of Streptomyces strains against fungal pathogens of tomato and wheat for a sustainable agriculture

open access: yesPest Management Science, EarlyView.
This study highlights the biocontrol potential of Streptomyces strain Strep_22. In vitro, it inhibits key fungal pathogens by 91.52%. In vivo, it significantly reduces disease incidence in wheat and tomato while enhancing biomass, shoot, and root development, offering a highly promising, sustainable ecological alternative to chemical pesticides ...

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.

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

open access: yesResponsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Cyanoacrylates. Herbicidal and photosynthetic inhibitory activity.

open access: yesAgricultural and Biological Chemistry, 1981
Various alkyl 3-phenylamino-2-cyano-and 2-ethoxycarbonylacrylates and 3-phenylamino-2-cyanoacrylonitriles were synthesized and assayed as inhibitors of the Hill reaction in isolated pea chloroplast suspensions and as pre-and post-emergent herbicides on mustard and barnyard grass.

Design, synthesis and herbicidal activity of novel cyclic phosphonates with diaryl ethers containing pyrimidine

open access: yes, 2019
Thirteen novel cyclic phosphates were rationally designed and synthesized by introducing diary ethers containing pyrimidine. All the target compounds were characterized by 1H, 13C, 31P NMR and HRMS.

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Preparation and bioactivity of 1,8-cineole derivatives [PDF]

open access: yes, 2009
The naturally occurring monoterpene 1,3,3-trimethyl-2-oxabicyclo[2.2.2]octane 1, commonly named 1,8-cineole and the major component in the leaf oil of many eucalypts, exhibits bioactivity, being potentially antimicrobial and pesticidal.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...
