Pesticidal compositions from prunus

A method for commercial-scale production of pesticidal plant compositions from vegetative Prunus growth, comprising:

• planting plants of a Prunus species where a spacing between plants is from 1 foot to 10 feet;
• growing the plants for a period of time sufficient to produce vegetative growth;
• harvesting the vegetative growth;
• and
• macerating the vegetative growth to provide a pesticidal plant composition.

A method for providing pesticidal plant compositions, comprising:

• producing Prunus biomass;
• chopping the Prunus biomass;
• and
• macerating the chopped Prunus biomass in water at a temperature of from 25° C. to 70° C. for a period of from 1 hour to 18 hours to provide a pesticidal water solution comprising at least one compound of the group consisting of 2-propanol, hexanal, trans-2-hexenal, 1-hexanol, trans-2-hexenol, cis-3-hexenol, mandelonitrile, benzoic acid, benzaldehyde, benzyl alcohol, and hydrocyanic acid and a residue of insoluble biomass.

A method for providing a pesticidal plant composition, comprising:

• planting plants of the family Rosaceae with a spacing between the plants of from 1 foot to 10 feet;
• growing the plants for a period of time from 2 weeks to 1 year;
• harvesting the growth over the period of time to provide Rosaceae plant biomass;
• chopping the Rosaceae biomass;
• combining the chopped biomass with water;
• macerating the chopped biomass in the water to obtain water containing dissolved volatile compounds separated from the chopped biomass and a residue of insoluble biomass.
