A paraffinic spray oil and a method of using the spray oil for controlling turfgrass pests is disclosed. The spray oil comprises paraffinic oil and a quick break emulsifier, which is formulated as an oil-in-water (O/W) emulsion for use. The paraffinic oil and emulsifier are present in a weight ratio ranging from about 95:5 to about 99.95:0.05, and preferably from about 98.5:1.5 to about 99.9:0.1. When applied to turfgrass, the O/W emulsion quickly releases the oil phase upon application to the turfgrass to contact pests thereon. When provided at sufficient paraffinic oil dosages, generally at least about 0.5 gal oil/acre and preferably in the range of about 0.5 gal/acre to about 60 gal/acre, the spray oil is effective in controlling a variety of turfgrass pests, particularly insect and fungal pests, with little or no phytotoxic effects. Further, use of the spray oil as indicated for controlling turfgrass pests also enhances the growth of turfgrass.

1. A method for enhancing the growth of turfgrass comprising: applying to turfgrass an oil-in-water emulsion comprising a paraffinic oil and a quick break emulsifier, wherein the oil-in-water emulsion quickly breaks upon application to the turfgrass to release the paraffinic oil from the oil-in-wate
1. A method for enhancing the growth of turfgrass comprising: applying to turfgrass an oil-in-water emulsion comprising a paraffinic oil and a quick break emulsifier, wherein the oil-in-water emulsion quickly breaks upon application to the turfgrass to release the paraffinic oil from the oil-in-water emulsion, and the oil-in-water emulsion is applied to provide a dosage of paraffinic oil to the turfgrass that is effective for enhancing the growth of turfgrass; wherein:the paraffinic oil comprises a paraffin having a carbon number ranging from about C16 to about C35, and the paraffinic oil has a paraffin content of at least about 80%;the dosage of paraffinic oil ranges from about 0.5 gal/acre to about 60 gal/acre;the weight ratio of the paraffinic oil to the quick break emulsifier is from about 95:5 to about 99.95:0.05; andwherein the composition does not comprise an herbicide. 2. The method of claim 1, wherein the weight ratio of the paraffinic oil to the quick break emulsifier is from about 99.1:0.9 to about 99.5:0.5. 3. The method of claim 2, wherein the weight ratio of the paraffinic oil to the quick break emulsifier is about 99.2:0.8. 4. The method of claim 1, wherein the oil-in-water emulsion comprises a paraffinic oil content ranging from about 1% to about 50% by weight. 5. The method of claim 4, wherein the oil-in-water emulsion comprises a paraffinic oil content ranging from about 10% to about 30% by weight. 6. The method of claim 1, wherein the paraffinic oil has a paraffin content of at least about 90%. 7. The method of claim 6, wherein the paraffinic oil has a paraffin content of at least about 99%. 8. The method of claim 1, wherein the dosage of paraffinic oil ranges from about 2 gal/acre to about 20 gal/acre. 9. The method of claim 1, wherein the dosage of paraffinic oil ranges from about 2 gal/acre to about 11 gal/acre. 10. The method of claim 1, wherein the dosage of paraffinic oil ranges from about 10 gal/acre to about 20 gal/acre. 11. The method of claim 1, wherein the quick break emulsifier comprises polyoxyethylene lauryl ether, an alcohol ethoxylate, a glycerol oleate, or any combination thereof. 12. The method of claim 1, wherein the quick break emulsifier comprises an alcohol ethoxylate, a glycerol oleate, or both. 13. The method of claim 1, wherein the turfgrass is selected from the group consisting of Fescues, Rye, Bent, Bahia, St. Augustine, Centipede, Kentucky bluegrass, Zoysia Native Grasses, Buffalo grass, Blue Grama, Wheatgrasses, Seashore Paspalum, Carpet Grass, Buffo, Beach Grass, and combinations thereof. 14. The method of claim 1, further comprising preparing the oil-in-water emulsion from about one hour to about two hours prior to the step of applying the oil-in-water emulsion to the turfgrass. 15. The method of claim 1, wherein the paraffinic oil resides on the turfgrass for a period of not less than one hour.
