Abstract
The present invention relates to compositions that include a combination of one or more pesticides and one or more adjuvants.
Claims41
A pesticidal composition comprising:
- a) a pesticide;
- and
- b) an adjuvant wherein the composition provides a synergistic kill rate.
A pesticidal composition comprising a pesticide;
- and an adjuvant, wherein the composition provides an observed kill rate that exceeds an expected kill rate, the expected kill rate calculated using the formula:
- E=[X+Y]−[(X×Y)/100],
- wherein
- E is the expected kill rate;
- X is efficacy expressed as % of untreated control of the pesticide;
- and
- Y is efficacy expressed as % of untreated control of the adjuvant.
A method for controlling or preventing a pest infestation comprising administering a composition of pesticide and adjuvant that provides an observed kill rate that exceeds an expected kill rate, wherein the expected kill rate calculated using the formula:
- E=[X+Y]−[(X×Y)/100],
- wherein
- E is the expected kill rate;
- X is efficacy expressed as % of untreated control of the pesticide;
- and
- Y is efficacy expressed as % of untreated control of the adjuvant.
A method for treating or preventing a pest comprising:
- applying an amount of pesticide at a locus together with an adjuvant, wherein the adjuvant is present in an amount sufficient to stabilize the formation of free radicals in the pesticide so as to increase the effectiveness of the pesticide and thereby decrease the amount of pesticide applied so as to achieve effective treatment or prevention.
A method for increasing a kill spectrum of a pesticide comprising:
- providing a pesticide at a locus together with an adjuvant, wherein the adjuvant is present in an amount sufficient to stabilize the formation of free radicals.
A pesticidal composition consisting essentially of
- a) a pesticide that is not an organophosphate;
- and
- b) an adjuvant, wherein the composition provides a synergistic kill rate.
A method for increasing the permeability of a pesticide to an insect or plant comprising exposing a cuticle of said insect or plant to an adjuvant wherein said adjuvant destabilizes said cuticle of said insect or plant.
A method for initiating a free radical reaction on insect or plant tissue thereby altering the permeability of biological membranes in said tissue comprising exposing said insect or plant tissue to an adjuvant that destabilizes the cuticle of said insect or plant.
A pesticidal composition comprising:
- a) a pesticide that is not an organophosphate;
- and
- b) an adjuvant, wherein the composition provides a synergistic kill rate,
- with the proviso that (i) said composition does not include an attractant, (ii), said composition is not an insecticidal paint, (iii) said composition is not encapsulated or in the form of a microcapsule, and (iv) said composition does not include a fungicide.
