Patent Images
1. A composition comprising an acceptable carrier and a urease inhibiting effective amount of one or more phosphoric triamide compounds of the formula:
- ##STR5## wherein;
X is oxygen or sulfur;
R1 is alkyl, cycloalkenyl, alkenyl, alkynyl, aralkyl or cycloalkyl;
R2 is R1, hydrogen, or R1 and R2 together may form an alkylene or alkenylene chain which may optionally include one or more heteroatoms of oxygen, nitrogen, or sulfur completing a 3, 4, 5, 6, 7 or 8 membered ring structure; and
R3, R4, R5 and R6 are individually hydrogen or alkyl having from 1 to about 4 carbon atoms.
