Research reveals how bee-friendly limonoids are made

(John Innes Centre) The best known limonoid, azadirachtin, is famous for being bee-friendly yet having a strong anti-insect effect. Due to the complex chemical structure of limonoids, it is difficult to chemically synthesize these natural products. As a result, their use is currently limited to what can be extracted from plant materials. “If this engineering could be achieved, then crops could be developed with an inherent resistance to insects, which could reduce reliance on chemical application for crop protection.”
