The fungicidal compositions may further comprise a pigment. The fungicidal compositions may be provided as oil-in-water (O/W) emulsions which may be used for controlling fungal disease, such as dollar spot or bentgrass dead spot or bermudagrass dead spot, in plants, such as turfgrasses. Methods of applying the fungicidal compositions are also provided. ## Claims ### Claim 1 A method of controlling a fungal pathogen of a plant, the method comprising applying to the plant an emulsifier, a paraffinic oil, a pigment, and boscalid, wherein the paraffinic oil, pigment, and boscalid are applied in amounts that are synergistically effective for controlling the fungal pathogen. ### Claim 2 (depends on 1) The method according to claim 1, further comprising mixing two or more of the paraffinic oil, the emulsifier, the pigment, and boscalid before applying to the plant. ### Claim 3 (depends on 1) The method according to claim 1, wherein the paraffinic oil comprises a paraffin having a number of carbon atoms ranging from about 16 to about 35. ### Claim 4 (depends on 1) The method according to claim 1, wherein the paraffinic oil comprises a paraffin having an average number of carbon atoms of about 23. ### Claim 5 (depends on 1) The method according to claim 1, wherein the paraffinic oil has a paraffin content of at least about 80%. ### Claim 6 (depends on 1) The method according to claim 1, wherein the paraffinic oil has a paraffin content of at least about 90%. ### Claim 7 (depends on 1) The method according to claim 1, wherein the paraffinic oil has a paraffin content of at least about 99%. ### Claim 8 (depends on 1) The method according to claim 1, wherein the method further comprises applying a silicone surfactant to the plant. ### Claim 9 (depends on 1) The method according to claim 1, wherein the pigment is a polychlorinated (Cu II) phthalocyanine. ### Claim 10 (depends on 8) The method according to claim 8, wherein the emulsifier comprises a natural or synthetic alcohol ethoxylate, an alcohol alkoxylate, an alkyl polysaccharide, a glycerol oleate, a polyoxyethylene-polyoxypropylene block copolymer, an alkyl phenol ethoxylate, a polymeric surfactant, a polyethylene glycol, a sorbitan fatty acid ester ethoxylate, or a combination thereof. ### Claim 11 (depends on 8) The method according to claim 8, wherein the emulsifier comprises a natural or synthetic alcohol ethoxylate, a polymeric surfactant, a sorbitan fatty acid ester, or a combination thereof, and the composition further comprises a polyethylene glycol according to formula IV: R1—O—(CH2CH2O)f—R2 wherein R1═H or CH2═CH—CH2 or COCH3; R2═H or CH2═CH—CH2 or COCH3; and f≧1. ### Claim 12 (depends on 1) The method according to claim 1, wherein the fungal pathogen is at least one of a fungus that causes dollar spot in turfgrass and a fungus that causes bentgrass dead spot or bermudagrass dead spot in a turfgrass. ### Claim 13 (depends on 1) The method according to claim 1, wherein the fungal pathogen is a fungus that blights leaf tissue in a turfgrass. ### Claim 14 (depends on 1) The method according to claim 1, wherein the fungal pathogen is a fungus that causes dollar spot in a turfgrass. ### Claim 15 (depends on 1) The method according to claim 1, wherein the fungal pathogen is selected from the group consisting of: Sclerotinia homoeocarpa and Ophiosphaerella agrostis. ### Claim 16 (depends on 1) The method according to claim 1, wherein the plant is one or more of: bentgrass, bluegrass, ryegrass, fescue, bermudagrass, bahiagrass, zoysia, beachgrass, wheatgrass or carpetgrass. ### Claim 17 (depends on 1) The method according to claim 1, wherein the plant is one or more of: creeping bentgrass, colonial bentgrass, perennial ryegrass, annual ryegrass, Kentucky bluegrass, common bermudagrass, hybrid bermudagrass, annual bluegrass, seashore paspalum, St. Augustinegrass, tall fescue, bahiagrass, zoysiagrass, centipedegrass, rough stalk bluegrass, buffalo grass, blue grama, or annual bentgrass. ### Claim 18 (depends on 1) The method according to claim 1, wherein the fungal pathogen is a fungus that causes bentgrass dead spot or bermudagrass dead spot in a turfgrass. ### Claim 19 (depends on 1) The method according to claim 1, wherein boscalid is applied to the plant at a rate from about 0.02 to about 0.12 oz per 1000 square feet. ### Claim 20 (depends on 1) The method according to claim 1, wherein the paraffinic oil is applied to the plant at a rate from about 0.9 to about 32 oz/1000 square ft.
