🌱 Hermaphroditism remains one of the biggest hidden risks in commercial cannabis production.

🔬 This review examines the genetic, hormonal, and environmental mechanisms controlling s*x expression instability in Cannabis sativa. The authors discuss how unintended pollination can reduce floral quality and cannabinoid yield, while also reviewing key drivers such as ethylene signaling, developmental stage, and environmental stress.

🧬 The paper further highlights practical tools for breeders and growers, including silver thiosulfate treatments, Raman spectroscopy, and s*x-linked molecular markers for early detection and feminized seed production.

🍌 One of the world's most important crops is under threat — and scientists may have found an answer in your spice rack.

Moko disease, caused by Ralstonia solanacearum race 2, is among the most destructive bacterial diseases affecting bananas and plantains. It causes yellowing, wilting, and ultimately plant death — spreading rapidly through plantations with few effective treatments available.

A new study by Luciano Martínez-Bolaños et al. tested the essential oil of Pimenta dioica (allspice) against this aggressive pathogen. GC-MS analysis identified 19 compounds in the oil, dominated by eugenol (72.6%), caryophyllene (6.13%), and Beta-Myrcene (4.17%).

The results are striking: complete inhibition of bacterial growth at just 500 µL/L. The estimated MIC95 came in at 297.6 µL/L — and plant trials on banana vitroplants confirmed that treatment at this concentration reduced disease severity and prevented internal corm discoloration, without causing any phytotoxic effects.

🌿 A plant-derived, natural alternative to chemical pesticides — with real potential for sustainable banana disease management.
