Turfgrass fungicide formulation with pigment
First Claim
1. A method for improving turfgrass health, the method comprising applying to the turfgrass an effective amount of a formulation comprising:
- a paraffinic oil;
one or more emulsifiers, each of which is independently selected from the group consisting of natural and synthetic alcohol ethoxylates, alcohol alkoxylates, glycerol oleate, and nonyl phenol ethoxylates;
a pigment;
a silicone surfactant; and
water,wherein the silicone surfactant represents from about 0.1 wt % to about 5 wt % of the total weight of the paraffinic oil, the one or more emulsifiers, the pigment, and the silicone surfactant;
wherein the one or more emulsifiers represent from about 0.5 wt % to about 5 wt % of the total weight of the paraffinic oil, the one or more emulsifiers, the pigment, and the silicone surfactant;
wherein the pigment represents from about 1 wt % to about 10 wt % of the total weight of the paraffinic oil, the one or more emulsifiers, the pigment, and the silicone surfactant; and
wherein the formulation is an oil-in-water emulsion and the one or more emulsifiers and the silicone surfactant are selected such that the pigment is maintained in dispersion in the oil-in-water emulsion for delivery to the turfgrass.

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.
