Abstract
This invention relates to a pesticidal compositions containing at least one pyrrolizidine alkaloid compound derived from a plant and endophyte combination, and applying the pesticidal compositions to another plan without pesticidal protection, where upon application of the composition, the plant confers pest protection. The pyrrolizidine alkaloid compound is of Formula (I) wherein: R═H or CH3 and R′═H, CH3, CHO, COCH3.
Claims54
A pesticidal composition obtained from an aqueous extraction of a plant and endophyte combination, wherein the aqueous extract contains at least one pyrrolizidine alkaloid compound, wherein the pyrrolizidine compound is of Formula [I] being:
- wherein:
- R═H or CH3 and
- H, CH3, CHO, COCH3.
A plant with enhanced pest protection characterised in that the plant confers said post protection upon application of a pesticidal composition wherein the pesticidal composition includes at least one pyrrolizidine alkaloid compound of Formula [I]:
- wherein:
- R═H or CH3 and
- R═H, CH3, CHO, COCH3,
- and further characterised in that the plant is not infected with an endophyte.
A method of producing a pesticidal composition by the steps of:
- (a) cultivating at least one plant or part thereof inoculated with at least one endophyte and,
- (b) extracting by way of aqueous extraction processes at least one pyrrolizidine alkaloid compound from the plant or part thereof to produce the pesticidal composition.
A method of conferring pest resistance to at least one plant by the steps of:
- (a) producing a pesticidal composition from a non-synthetic source containing at least one pyrrolizidine alkaloid compound;
- and,
- (b) applying the pesticidal composition to the medium in which the plant is growing allowing the plant to absorb the composition via the plant roots.
A method of conferring pest protection to at least one plant by the steps of:
- (a) producing a pesticidal composition from a natural source containing at least one pyrrolizidine alkaloid compound;
- and,
- (b) applying the pesticidal composition to a plant on which increased pest protection is to be conferred.
A method of conferring pest protection to at least one plant by the steps of:
- (a) cultivating at least one plant or part thereof inoculated with at least one endophyte;
- (b) extracting at least one pyrrolizidine alkaloid compound from the plant or part thereof to form a pesticidal composition and;
- (c) applying the composition to a plant on which increased pest protection is to be conferred.
Use of an endophyte producing at least one pyrrolizidine alkaloid compound when in combination with a grass cultivar, to confer pest resistance to at least one plant that is not infected with an endophyte.
