Plant essential oils for pest and disease management
نویسنده
چکیده
Certain essential plant oils, widely used as fragrances and #avors in the perfume and food industries, have long been reputed to repel insects. Recent investigations in several countries con"rm that some plant essential oils not only repel insects, but have contact and fumigant insecticidal actions against speci"c pests, and fungicidal actions against some important plant pathogens. As part of an e!ort aimed at the development of reduced-risk pesticides based on plant essential oils, toxic and sublethal e!ects of some essential oil terpenes and phenols have been investigated using the tobacco cutworm (Spodoptera litura) and the green peach aphid (Myzus persicae) as model pest species. In this paper I review (i) the range of biological activities of essential oils and their constituents; (ii) their toxicity and proposed mode-of-action in insects; (iii) their potential health and environmental impacts as crop protectants; and (iv) commercialization of pesticides based on plant essential oils.

In order to search for alternative control methods to synthetic pesticides, the potential of essential oils from Allium sativum (L.) (Alliaceae); was evaluated as fumigants against Callosobruchus maculatus (fab.) (Coleoptera: Bruchidae), a pest that attacks pulses during storage. Chickpea seeds were infested with 10 pairs of newly emerged weevils and, fumigated with 0, 1, 2, 3, or 4μl of essent...

The red bud borer Resseliella oculiperda (Rübs.) is a pest insect of apple trees when rootstocks are grafted with scion buds by 'shield budding'. The female midges are attracted to the wounds of the grafted buds where they lay their eggs. The larvae feed on the cambium and destroy the buds completely or partially, leading to bad union of the buds with the rootstocks. Budding strips are used ver...
