Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

Pest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...

Photoinduced Selective Construction of Densely Functionalized Spirocyclic Ethers With Carbyne Equivalents

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
A reactivity programmed cascade between carbyne equivalents and allylic benzoates was developed that sequentially orchestrates all three reactivity modes of carbyne equivalents, enabling the rapid installation of three σ‐bonds at a single carbon center and providing efficient, scalable access to structurally diverse spirocyclic ethers. ABSTRACT Carbyne
