Evaluation of repellent and insecticidal properties of a novel granite dust product in crop protection
Journal of Pest Science 91 (4), 1345-1352
Abstract: Inert rock dusts, such as diatomaceous earth, represent effective products for insect pest management. We investigated the properties of a novel granite dust product in different formulations as a repellent and insecticidal agent against two important horticultural crop pests (Plutella xylostella and Trichoplusia ni). Foliar application of granite dust (dry and in aqueous solution) reduced larval feeding damage of P. xylostella and T. ni on cabbage leaves. In the case of P. xylostella, aqueous formulation of granite dust with surfactant had a significant insecticidal effect on larvae. In oviposition bioassays, adult P. xylostella female insects oviposited significantly fewer eggs on cabbage leaves treated with granite dust than on control leaves. Our results demonstrate, for the first time, the potential use of granite dust as a pest management treatment providing repellent and insecticidal activities exceeding other mineral and dust-based pest management products.
