Abstract
Iminocarbonylphosphonates, such as dimethyl 1,1-bis (dimethylamino)methyleneaminocarbonylphosphonate, useful as plant growth retardants.
Claims31
A plant growth retardant composition comprising:
- (a) at least one of the following:
- a surfactant, a solid or liquid diluent;
- and (b) an effective amount of a compound of the formula:
- ##STR23## where R is alkyl of 1 to 4 carbon atoms or benzyl;
- R.sub.1 is Na, K, NH.sub.4, or R;
- R.sub.4 is NR.sub.2 R.sub.3, or OR.sub.5 ;
- where
- R.sub.2 is hydrogen or alkyl of 1 to 12 carbon atoms;
- R.sub.3 is hydrogen or alkyl of 1 to 3 carbon atoms;
- and
- R.sub.5 is alkyl of 1 to 3 carbon atoms;
- and
- R.sub.6 is NR.sub.2 R.sub.3, hydrogen, or alkyl of 1 to 3 carbon atoms.
