Patent ID: 8053392

Claim:
A precursor composition for 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, the amount of the inactive ingredients being sufficient relative to the quantity of the active pesticide ingredients to cause the precursor composition to spontaneously foam a microemulsion having particles that are no larger than 10μ when the precursor composition is diluted with water.
