The present invention discloses amides and thioamides substituted in the .alpha. or .beta. position with substituted pyrazoles which are useful as herbicides.

Phenyl pyrazole morpholine amides

Furyl pyrazole amides

Thienyl pyrazole amides

Furyl pyrazole thioamides

Thienyl pyrazole thioamides

Phenyl pyrazole thioamides

Certain new 1-(substituted-hydrocarbyl)-di- and trihalopyrazoles have been synthesized. They possess herbicidal and plant growth regulatory activity. The hydrocarbyl group, i.e., alkylene or alkenylene group at the 1-nitrogen of the pyrazole nucleus has either a carboxyl group, an hydroxymethyl group, an hydroxymethyl lower-alkanoate group a carboxylic lower-alkyl ester group a cyano group or a carboxylic amide group. The new compounds are prepared and isolated by conventional chemical reactions and procedures. An improved reaction for making the new carboxylic acids is described. Weed control methods and compositions for herbicidal use are also described.

Compounds of the formula: ##SPC1## Wherein R.sub.1 and R.sub.2 are the same or different and are hydrogen, alkyl of from 1 to 6 carbon atoms, inclusive, or phenyl; R.sub.3 is hydrogen, alkyl of from 1 to 8 carbon atoms, inclusive, phenyl, or benzyl; R.sub.4 is hydrogen or alkyl of from 1 to 6 carbon atoms, inclusive, and R.sub.3 and R.sub.4 can be joined together to form a heterocyclic ring selected from the group consisting of morpholine, pyrrolidine or piperidine; X is oxygen or sulfur; A and B are the same or different, and are hydrogen, alkyl of from 1 to 6 carbon atoms inclusive, cycloalkyl of from 3 to 7 carbon atoms, inclusive, haloalkyl, and halogen; Z is an alkyl group of from 1 to 6 carbon atoms, inclusive, or a cycloalkyl group of from 3 to 7 carbon atoms provided that when A and B are halogen, Z is located at the 4 or 5 positions. Methods for preparing the compounds, and agricultural compositions comprising the compounds with carriers for use as herbicides by application to foliage, soil or ponds for the control of unwanted vegetation are disclosed.
