摘要:
Disclosed herein are herbicidal pyridine compounds substituted at the 2- or 6-position with an OR.sub.2 moiety where R.sub.2 is hydrogen, lower alkyl, halomethyl, lower cyanoalkyl, alkenyl or alkynyl, as well as herbicidal compositions and herbicidal use of these compounds.
摘要:
Disclosed herein are 2- or 6-fluoromethyl-3-pyridinecarboxylate derivatives with 5-[(heterocyclic)ylidene]amino substitution useful as herbicides and herbicide intermediates.
摘要:
Substituted pyridines characterized by having been substituted in the 3-position with an isoxazolyl or isothiazolyl radical. A method of using such pyridines as herbicides and herbicidal compositions containing such pyridines are described. Methods of preparing such substituted pyridines are also disclosed.
摘要:
Disclosed herein are 3,5-pyridinedicarboxylic acid derivatives having substituted thio, sulfinyl or sulfonyl substitution at the 4 position which are useful as herbicides and herbicide precursors.
摘要:
The present invention relates to a class of 5-haloalkyl-3-hydroxy-1-(C.sub.1-2 alkyl)pyrazoles useful as precursors for an active class of phenoxypyrazole herbicides.
摘要:
Compounds of the formula ##STR1## are disclosed as herbicides. Disclosed herein are cyclic amides of pyridine 3,5-carboxylic acids substituted at the 2- and/or 6-position with a fluorinated methyl group. Also disclosed are herbicidal use of such compounds and compositions containing them.
摘要:
Hydrolysis of N-phosphonomethyl-2-oxazolidone and separation of the carbon dioxide co-product prior to oxidation of the hydrolyzate to glyphosate results in a process of significantly increased efficiency over the previously described processes.
摘要:
There are disclosed novel 2,6-substituted-3-pyridinecarboxylic acids, esters, and salts useful as herbicides, and as intermediates which provide herbicides.
摘要:
2,4-Disubstituted-5-thiazolecarboxylic acids and derivatives thereof have been found to reduce herbicidal injury of corn, rice and sorghum plants due to the application thereto of acetamide herbicides.
