Compositions having at least one compound which inhibits the formation of Hemipteran stylet sheaths and/or degrades hemipteran style sheaths that have already been formed, and thus deters or blocks hemipteran insects from feeding on plants, especially agriculturally important plants and methods of use of such compositions are described. Such compositions can be applied onto plants by spraying, dripping, or other methods and/or can be applied to the soil for uptake by the roots. These compositions and methods prevent and/or reduce the transmission of vascular associated diseases (caused by hemipteran vector-borne pathogens) to plants.
A composition for preventing or reducing hemipteran insect feeding on a plant comprising an agriculturally acceptable carrier, at least one compound effective in preventing or reducing hemipteran insect feeding in an amount effective in preventing formation of said hemipteran insect's stylet sheath or in degrading said hemipteran insect's stylet sheath, and optionally an adjuvant, wherein said compound is selected from the group consisting of at least one carbohydrate-degrading enzyme, at least one protease, at least one small molecule that prevents stylet sheath formation, and a combination thereof.
A method of preventing formation of a hemipteran insect's stylet sheath comprising applying to said plant a composition in an amount effective to prevent formation of said hemipteran insect's stylet sheath, wherein said composition comprises an agriculturally acceptable carrier, at least one compound effective in preventing formation of said hemipteran insect's stylet sheath, and optionally an adjuvant, wherein said compound is selected from the group consisting of at least one carbohydrate-degrading enzyme, at least one protease, at least one small molecule that prevents stylet sheath formation, and a combination thereof.
A method of degrading a hemipteran insect's stylet sheath comprising applying to said plant a composition in an amount effective to degrade said hemipteran insect's stylet sheath, wherein said composition comprises an agriculturally acceptable carrier, at least one compound effective in degrading said hemipteran insect's stylet sheath, and optionally an adjuvant, wherein said compound is selected from the group consisting of at least one carbohydrate-degrading enzyme, at least one protease, at least one small molecule that prevents stylet sheath formation, and a combination thereof.
A method for reducing or preventing transmission of a vascular associated disease from a hemipteran insect that is a carrier of said vascular associated disease to a plant comprising applying to said plant an agriculturally acceptable carrier, at least one compound in an amount effective to reduce or prevent said hemipteran insect from feeding on said plant, and optionally an adjuvant, wherein said compound is selected from the group consisting of at least one carbohydrate-degrading enzyme, at least one protease, at least one small molecule that prevents stylet sheath formation or degrades stylet sheath formation, and a combination thereof, and wherein reduction or prevention of feeding of said hemipteran insect on said plant results in reducing or prevention of transmission of said vascular associated disease.
A kit for reducing or preventing transmission of a vascular associated disease from a hemipteran insect that is a carrier of said vascular associated disease to a plant, said kit comprising a first container which contains at least one compound effective in reducing or preventing said hemipteran insect from feeding on said plant;
