Herbicidal compositions of glyphosate, its salts, diquat, or paraquat in combination with a compound of the following formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and n are as defined. Preferred are combinations of glyphosate, its salts, diquat, or paraquat with 2-chloro-5-(4-bromo-1-methyl-5-(trifluoromethyl)-1H-pyrazol-3-yl)-4-fluoro benzoic acid, 1-methylethyl ester.

Herbicidal compositions comprising aryl-5-haloalkylpyrazoles and

The disclosure herein relates to a process for the preparation of compounds according to Formula N ##STR1## which comprises using a compound of Formula M ##STR2## as starting material for alkylation to said compounds of Formula N in an inert solvent at temperatures within the range of 0.degree.-200.degree. C. wherein

Process for the preparation of substituted

The invention herein relates to certain substituted-arylpyrazole compounds, herbicidal compositions containing same, herbicidal methods of use and processes for preparing said compounds.

Herbicidal substituted aryl-haloalkylpyrazoles

The invention herein relates to titled compounds having the structure ##STR1## wherein the R.sub.1 -(R.sub.4).sub.n members are as defined in the claims. Characteristic features of these compounds are the haloalkyl R.sub.2 radical and cyclization of two R.sub.4 members at the meta and para positions of the phenyl ring to form a substituted benzoxazinone ring fused to the phenyl or benzthiazinone ring. Such compounds are useful as active ingredients in herbicidal compositions to control undesirable weeds in various crops.

Herbicidal benzoxazinone- and benzothiazinone-substituted pyrazoles

This disclosure relaes to arylsulfenyl derivatives of benzyl and aryl esters of N-phosphonomethylglycines. This disclosure further relates to herbicidal compositions containing arylsulfenyl derivatives of benzyl and aryl esters of N-phosphonomethylglycines, to the use thereof, and to herbicidal methods employing such compounds and compositions.

Alkyl N-arylsulfenyl-N-diaryloxy-phosphinylmethylglycinates

This invention relates to novel esters of N,N'-methylene-bis-[N-[(diaryloxyphosphinyl)methyl]glycine] which are useful as herbicides. The invention also relates to herbicidal methods and compositions employing the novel esters.

Esters of N,N'-methylene-bis-[N-[(diaryloxyphosphinyl)methyl]glycine] as

This disclosure relates to arylsulfenyl derivatives of benzyl and aryl esters of N-phosphonomethylglycines. This disclosure further relates to herbicidal compositions containing arylsulfenyl derivatives of benzyl and aryl esters of N-phosphonomethylglycines, to the use thereof, and to herbicidal methods employing such compounds and compositions.

This disclosure relates to novel N-substituted triesters of N-phosphonomethylglycine which are useful as herbicides. This disclosure further relates to herbicidal compositions containing such N-substituted N-phosphonomethylglycinates and to herbicidal methods employing such compounds and compositions.

N-Substituted triesters of N-phosphonomethylglycine

Certain N-thiolcarbonyl derivatives of N-phosphonomethylglycinonitrile esters are novel chemical compounds having desirable herbicidal properties.

N-Thiolcarbonyl derivatives of N-phosphonomethylglycinonitrile esters,

This disclosure relates to N-nitroso-N-phosphonomethylglycine triesters and their use as herbicides and in herbicidal compositions. More particularly, this disclosure relates to N-nitroso-N-phosphonomethylglycine esters wherein a lower alkyl or benzyl group is bonded to the carboxyl moiety and a phenyl or substituted phenyl group is bonded to phosphorus.

N-Nitroso-N-phosphonomethylglycine esters and the herbicidal use thereof

This disclosure relates to N-nitroso-N-phosphonomethylglycinonitrile compounds, the preparation thereof and their use as herbicides and in herbicidal compositions.

N-Nitroso-N-phosphonomethylglycinonitrile esters and the herbicidal use

This disclosure relates to novel ester derivatives of N-arylthio-N-phosphonomethylglycinonitrile which are useful as herbicides. This disclosure further relates to herbicidal compositions containing such N-phosphonomethylglycinonitriles and to herbicidal methods employing such compounds and compositions.
