Cinnamaldehyde and diallyl disulfide formulations and methods of use

Abstract

The present invention relates to agricultural emulsion concentrates which form stable oil-in-water emulsions when diluted with water. More specifically, the invention relates to stable oil-in-water emulsions which include cinnamaldehyde and diallyl disulfide with a Calsogen® EH and Surfonic® CO 36 emulsion system. The increased stability of the emulsion allows for efficient mixing of the emulsion ingredients and effective storage and application of the cinnamaldehyde and diallyl disulfide to areas in need of nematode protection or treatment.

1 . An agricultural formulation comprising a synergistic amount of cinnamaldehyde and diallyl disulfide, wherein the ratio of cinnamaldehyde to diallyl disulfide is from about 5:1 to about 10:1. 
     
     
         2 . The formulation of  claim 1  wherein the ratio of cinnamaldehyde to diallyl disulfide is about 5:1. 
     
     
         3 . The formulation of  claim 1  wherein the ratio of cinnamaldehyde to diallyl disulfide is about 10:1. 
     
     
         4 . The formulation of  claim 1  further comprising a lipophilic solvent. 
     
     
         5 . The formulation of  claim 4  wherein the lipophilic solvent is selected from the group consisting of soybean oil, methyl oleate, ethyl lactate, and methyl soyate. 
     
     
         6 . The formulation of  claim 5  wherein the lipophilic solvent is soybean oil. 
     
     
         7 . The formulation of  claim 1  further comprising a surfactant. 
     
     
         8 . The formulation of  claim 7  wherein the surfactant is a castor oil ethoxylate. 
     
     
         9 . The formulation of  claim 7  wherein the surfactant is an iso-C 12 alkylbenzene sulphonate calcium salt. 
     
     
         10 . A method for suppressing plant damage by plant pathogens comprising applying the formulation of  claim 1  to the locus, soil or seeds of plants in need of said treatment. 
     
     
         11 . The method of  claim 10  wherein the formulation is applied to the locus of plants. 
     
     
         12 . The method of  claim 10  wherein the formulation is applied to the soil of plants. 
     
     
         13 . The method of  claim 10  wherein the formulation is applied to the seeds of plants. 
     
     
         14 . The method of  claim 10  wherein the plant pathogen is a nematode. 
     
     
         15 . The method of  claim 10  wherein the plant is a cucumber. 
     
     
         16 . The method of  claim 10  wherein the plant is a melon. 
     
     
         17 . The method of  claim 10  wherein the plant is a tomato. 
     
     
         18 . The method of  claim 10  wherein the formulation is applied by spraying. 
     
     
         19 . The method of  claim 10  wherein the formulation is applied by dripping.
