Synergistic pesticidal compositions and methods for delivery of active ingredients

A method of synergistically enhancing the pesticidal activity of at least one pesticidal active ingredient adapted to control at least one target pest organism comprising:

• providing at least one pesticidal active ingredient comprising a strobilurin active for said at least one target pest organism, wherein the strobilurin comprises pyraclostrobin, azoxystrobin, picoxystrobin, or trifloxystrobin;
• adding a synergistically effective concentration of at least one C6-C10 unsaturated aliphatic acid comprising at least one unsaturated C—C bond, or an agriculturally acceptable salt thereof, to said pesticidal active ingredient to provide a synergistic pesticidal composition;
• and
• applying said synergistic pesticidal composition in a pesticidally effective concentration to control said at least one target pest organism;
• wherein when the strobilurin is pyraclostrobin or azoxystrobin, a weight ratio of the concentrations of said pesticidal active ingredient and said C6-C10 unsaturated aliphatic acid is between about 100:1 and 1:10,000, and wherein when the strobilurin is picoxystrobin, a weight ratio of the concentrations of said pesticidal active ingredient and said C6-C10 unsaturated aliphatic acid is between about 100:1 and 1:10, and wherein when the strobilurin is trifloxystrobin, a weight ratio of the concentrations of said pesticidal active ingredient and said C6-C10 unsaturated aliphatic acid is between about 10:1 and 1:10.

A pesticidal composition comprising:

• one or more pesticidal agents comprising a strobilurin, wherein the strobilurin comprises pyraclostrobin, azoxystrobin, picoxystrobin, or trifloxystrobin;
• and
• one or more unsaturated C6-C10 aliphatic acids or agriculturally compatible salts thereof, having at least one unsaturated C—C bond,
• wherein when the strobilurin is pyraclostrobin or azoxystrobin, said one or more unsaturated C6-C10 aliphatic acids produce a synergistic effect on the pesticidal activity of the pesticidal composition in comparison to the pesticidal activity of the pesticidal agent alone and are present in a respective synergistically active weight concentration ratio between about 1:2000 and 100:1 of the pesticidal agent to the one or more unsaturated C6-C10 aliphatic acids, and wherein when the strobilurin is picoxystrobin, said one or more unsaturated C6-C10 aliphatic acids produce a synergistic effect on the pesticidal activity of the pesticidal composition in comparison to the pesticidal activity of the pesticidal agent alone and are present in a respective synergistically active weight concentration ratio between about 1:100 and 10:1 of the pesticidal agent to the one or more unsaturated C6-C10 aliphatic acids, and wherein when the strobilurin is trifloxystrobin, said one or more unsaturated C6-C10 aliphatic acids produce a synergistic effect on the pesticidal activity of the pesticidal composition in comparison to the pesticidal activity of the pesticidal agent alone and are present in a respective synergistically active weight concentration ratio between about 1:10 and 10:1 of the pesticidal agent to the one or more unsaturated C6-C10 aliphatic acids.

A method of synergistically enhancing the pesticidal activity of at least one pesticidal active ingredient adapted to control at least one target pest organism comprising:

• providing at least one pesticidal active ingredient comprising a strobilurin active for said at least one target pest organism, wherein the strobilurin comprises pyraclostrobin, azoxystrobin, picoxystrobin, or trifloxystrobin;
• adding a synergistically effective concentration of at least one C6-C10 unsaturated aliphatic acid or an agriculturally acceptable salt thereof to provide a synergistic pesticidal composition;
• mixing said synergistic pesticidal composition with at least one formulation component comprising a surfactant to form a synergistic pesticidal concentrate;
• diluting said synergistic pesticidal concentrate with water to form a synergistic pesticidal emulsion;
• and
• applying said synergistic pesticidal emulsion at a pesticidally effective concentration and rate to control said at least one target pest organism;
• wherein when the strobilurin is pyraclostrobin or azoxystrobin, a weight ratio of the concentrations of said pesticidal active ingredient and said C6-C10 unsaturated aliphatic acid is between about 1:100 and 1:10,000, and wherein when the strobilurin is picoxystrobin, a weight ratio of the concentrations of said pesticidal active ingredient and said C6-C10 unsaturated aliphatic acid is between about 100:1 and 1:10, and wherein when the strobilurin is trifloxystrobin, a weight ratio of the concentrations of said pesticidal active ingredient and said C6-C10 unsaturated aliphatic acid is between about 10:1 and 1:10.
