ABSTRACT:
The foliage and stems of plant species from the family Rosaceae, genusPrunus,yield natural pesticides when macerated. Hydrodistillation of macerated plant biomass yields a concentrated solution of organic volatile compounds that act synergistically as a natural pesticide. Volatile compounds liberated fromPrunusbiomass include 2-propanol, hexanal, trans-2-hexenal, 1-hexanol, cis-3-hexenol, mandelonitrile, benzoic acid, benzaldehyde, benzyl alcohol, hydrocyanic acid and others. These compounds may be removed from the distillate and reformulated to form a standard concentrated solution, with benzaldehyde, mandelonitrile and hydrogen cyanide being the major components. The extracts may be used as a soil treatment or soil fumigant for soil-borne pests. They also may be formulated for application as solutions with or without a surfactant or formulated as powders for foliar treatment. In a particular application, such extracts may be applied to postharvest commodities such as fruits, vegetables, roots, grains and nuts to protect against certain fungi and insects.
