Abstract
This disclosure relates to N-(substituted carbonyl) triester derivatives of N-phosphinylmethylglycine wherein a substituted thiocarbonyl, RS(CO)--, a substituted sulfinylcarbonyl, ##STR1## or a substituted sulfonyl carbonyl, ##STR2## group is bonded to the nitrogen atom, to herbicidal compositions containing the same and to the herbicidal use thereof.
Claims12
A compound of the formula ##STR15## wherein R is selected from the group consisting of lower alkyl, lower alkenyl, lower alkynyl or benzyl;
- R.sub.1 is selected from the group consisting of lower alkyl or lower alkoxyalkyl;
- Z is sulfinyl, and X is phenoxy or phenoxy substituted with up to three groups individually selected from the class consisting of lower alkyl, lower alkoxy, halogen and nitro.
A herbicidal composition comprising an inert adjuvant and a herbicidally effective amount of a compound of the formula ##STR16## wherein R is selected from the group consisting of lower alkyl, lower alkenyl, lower alkynyl or benzyl;
- R.sub.1 is selected from the group consisting of lower alkyl or lower alkoxyalkyl;
- Z is sulfinyl, and X is phenoxy or phenoxy substituted with up to three groups individually selected from the class consisting of lower alkyl, lower alkoxy, halogen and nitro.
A method of controlling undesired plants which comprises contacting said plants or the plant growth medium with a herbicidal amount of a compound of the formula ##STR17## wherein R is selected from the group consisting of lower alkyl, lower alkenyl, lower alkynyl or benzyl;
- R.sub.1 is selected from the group consisting of lower alkyl or lower alkoxyalkyl;
- Z is sulfinyl, and X is phenoxy or phenoxy substituted with up to three groups individually selected from the class consisting of lower alkyl, lower alkoxy, halogen and nitro.
