New research highlights the potential of rose essential oil as a natural and effective alternative to chemical pesticides in protecting tomato plants from pests. Demonstrating dual benefits, REO reduces pest damage and promotes predator attraction without harmful side effects, offering a sustainable solution for organic farming practices.
Plants-derived essential oils find applications in various industries, such as detergents, cosmetics, pharmacology, and food additives. Moreover, EOs have an exceptional safety profile, and their numerous bioactivities greatly benefit human health. Beyond these benefits, EOs have also been found to illicit insect-repellent responses by inducing neurotoxic effects.
To address this, a research team led by Professor Gen-ichiro Arimura from the Department of Biological Science and Technology at theassessed the efficacy of 11 EOs in activating tomato defense responses. “EOs used as fragrances for various purposes contain odor components, which may have the ability to work like volatile compounds in conferring pest resistance. We aimed to investigate the effects of these EOs on plants’ insect pest resistance,” says Prof. Arimura.

Rose essential oil: A safe pesticide for organic agricultureFollowing injury, plants release terpenoids to enhance their defenses. Researchers studying terpenoid-enriched essential oils (EOs) have found that rose EO (REO) can stimulate defense genes in tomato leaves. Furthermore, REO attracts herbivores that protect the plant from the moth species, Spodoptera litura, and Tetranychus urticae, a mite pest.
