N-phosphonomethylglycine and novel derivatives thereof useful as phytotoxicants or herbicides.

N-Phosphonomethylglycine phytotoxicant compositions

Novel hydroxyalkylesters of N-phosphonomethylglycine have been identified which prove to be effective gametocides.

Gametocides

N-phosphonomethylglycine and novel derivative thereof useful as phytotoxicants or herbicides.

Thioester of n-phosphonomethylglycine

This invention relates to a new class of organic chemical compounds. More particularly, this invention is concerned with amido and hydrazido derivatives of N-phosphinothioylmethylglycine esters. This class of compounds has been found to be useful as herbicides.

Hydrazido derivatives of N-phosphinothioylmethylglycine esters

Novel herbicidal oxime derivatives of aryl glyphosate esters are described and claimed along with a process for producing such oxime derivatives.

Herbicidal glyphosate oxime derivatives

Bis-(alkoxy)tetrathiotricarboxylates are disclosed as well as herbicidal compositions containing such compounds and the use of such compounds as post-emergence herbicides.

Bis-(alkoxy)tetrathiotricarboxylates and use as herbicides thereof

Novel N(aminophosphinylmethyl)glycine derivatives are described that show significant herbicidal activity.

N(Aminophosphinylmethyl) glycine derivatives

N-alkoxythione derivatives of N-phosphonomethylglycine are novel compounds with utility as herbicides and in plant growth regulating applications.

N-Phosphonomethylglycine derivatives and use as herbicides

This disclosure relates to alkyl N-trifluoroacetyl-N-phosphonomethylglycine amide and hydrazide derivatives, to herbicidal compositions containing same and to the herbicidal use thereof. These amide and hydrazide derivatives are useful as pre-emergent and/or post-emergent herbicides.

Amide derivatives of N-trifluoroacetyl-N-phosphonomethylglycine,

Esters of N-phosphonomethylglycine

This disclosure relates to novel silyl esters of N-phosphonomethylglycine useful as post-emergence herbicides.

Novel silyl esters of N-phosphonomethylglycine

This disclosure relates to N-organo-N-phosphonomethylglycine-N-oxides and derivatives thereof. These compounds are useful to increase the sucrose content of sugarcane.

N-Organo-phosphonomethylglycine-N-oxides and the use thereof to increase

This invention relates to a new class of organic chemical compounds. More particularly, this invention is concerned with amido and hydrazido derivatives of N-trifluoroacetyl-N-phosphinothioylmethylglycine. This class of compounds has been found to be useful as intermediates in producing amido and hydrazido derivatives of N-phosphinothioylmethylglycine esters which show herbicidal activity. Some of the class of compounds of this invention also show herbicidal activity when applied to certain varieties of weeds or undesired plants.
