Auxin acid-catalyzed stable microemulsion pesticide formulation

A stable water based microemulsion pesticide formulation comprising the combination of:

• a quantity of active pesticide ingredients including from about 20% to about 40% by weight of an auxin ester, from about 0.5% to about 3% by weight of a protox inhibitor compatible with the auxin ester, and from about 5% to about 12% by weight of an auxin acid stabilizing agent;
• and
• an amount of inactive agents including from about 25% to about 35% by weight of a microemulsifier, from about 8% to about 12% by weight of a stabilizing co-emulsifier for the pesticides, and from about 7% to about 12% by weight of a solvent for the pesticides,
• said particles being dispersed in an amount of dilution water,
• the amount of the inactive ingredients being sufficient relative to the quantity of the active pesticide ingredients to cause the precursor to spontaneously form a microemulsion wherein the particles are no larger than about 10μ when the precursor is diluted with water.

A precursor for a stable water based microemulsion pesticide formulation comprising the combination of:

• a biologically effective quantity of active pesticide ingredients including an auxin ester, a protox inhibitor compatible with the auxin ester, and an auxin acid stabilizing agent;
• and
• an amount of inactive agents including a microemulsifier, a stabilizing co-emulsifier for the pesticides, and a solvent for the pesticides,
• the relative amounts of the inactive ingredients being sufficient with respect to the quantity of the active pesticide ingredients to cause the precursor to spontaneously form a microemulsion wherein the particles are no larger than about 10μ when the precursor is diluted with water, and a sufficient amount of the auxin acid stabilizing agent being present to form overall net negative repulsion charges on the particles to prevent coalescence of the microemulsion particles to maintain the physical stability of the microemulsion and to adjust the pH of the continuous water phase to a level to maintain the chemical stability of the microemulsion.
