  • Patent number: 9999219
    Abstract: 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.

  • Patent number: 9826738
    Abstract: Oil-in-water fungicidal formulations are prepared having pigment dispersed therein, the pigment being stable within the oil-in-water emulsion as a result of the addition of suitable silicone surfactants and suitable emulsifiers. The formulations can be prepared either as a 2-pack formulation or as a single formulation. In the case of the single formulation polyethylene glycol is also added. In either case, the formulations show a synergistic effect through the addition of the pigment, the resulting formulations having an increased efficacy. Further, the formulations show a synergistic effect when mixed with conventional chemical fungicides, both being added in reduced amounts compared to recommended rates.
