Formulations for improved pesticide-fertilizer compositions

Abstract

A novel composition is disclosed, comprising (a) an aqueous solution of an N-P or N-P-K fertilizer and (b) an attapulgite clay. The composition provides improved emulsion stability when combined with an emulsifiable concentrate of an organophosphorus compound of the formula ##STR1## in which R.sup.1 is selected from the group consisting of C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, and C.sub.1 -C.sub.6 alkylthio, R.sup.2 is selected from the group consisting of C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, and C.sub.1 -C.sub.6 alkylthio, R.sup.3 is selected from the group consisting of C.sub.1 -C.sub.6 alkyl, C.sub.2 -C.sub.8 alkylthioalkyl, phenyl, and C.sub.7 -C.sub.12 phenylthioalkyl, the phenyl rings optionally substituted with halogen, C.sub.1 -C.sub.3 alkyl, nitro, or C.sub.1 -C.sub.3 alkylsulfinyl, X is oxygen or sulfur, and Y is oxygen or sulfur.
