Insecticidal and acaricidal formulation of increased stability

Abstract

Abstract FORMULATION OF INCREASED STABILITY CONTAINING (1) THE NORMALLY UNSTABLE INSECTICIDALLY AND ACARICIDALLY ACITIVE COMPOUND O,O - DIETHYL-O-QUINOXAL-2-YL-THIONOPHOSPHORIC ESTER, E.G. IN AN AMOUNT OF ABOUT 20-80% BY WEIGHT, (2) A DILUENT SUCH AS A HIGHER BOILING HYDROCARBON AND/ OR HIGHER BOILING ESTER, E.G. N AN AMOUNT OF ABOUT 1580% BY WEIGHT, AND (3) A STABILIZER SUCH AS (A) A TERTIARY AMINE, E.G. IN AN AMOUNT OF ABOUT 0.1-10% BY WEIGHT, (B) A DIPOLAR APROTIC SOLVENT, E.G. IN AN AMOUNT OF ABOUT 0.01-10% BY WEIGHT, OR A MIXTURE OF (A) AND (B) IN AN AMOUNT OF ABOUT 0.01-20% BY WEIGHT; OPTIONALLY INCLUDING (4) A SURFACTANT SUCH AS EMULSIFYING AND/OR DISPERSING AGENT; AND METHODS OF IMPROVING AND INCREASING THE STABILITY, E.G. IN STORAGE, OF O,O-DIETHYL-O-QUINOXAL-2YL-THIONOPHOSPHORIC ACID ESTER, ESPECIALLY WHEN ASSOCIATED OR ADMIXED WITH DILUENTS, WHICH CONTEMPLATE THE ADMIXING OF THE ABOVE-NOTED COMPONENTS, (1), (2) AND (3), AND OPTIONALLY ALSO (4), E.G. IN THE STATED AMOUNTS.
