Abstract: This invention concerns certain substituted diphenyl ethers, their method of preparation, and herbicidal uses thereof.

Abstract: A process for preparing a diphenyl ether of the formula: ##STR1## wherein: X is hydrogen or halogen;Y is hydrogen, halogen, cyano, trifluoromethyl, or an alkyl radical containing 1 to 4 carbon atoms;Z is oxygen or sulfur;R is a methylidene or monosubstituted methylidene, wherein the substituent is selected from the group consisting of alkyl, oxoalkyl and hydroxyalkyl radicals containing from 1 to 4 carbon atoms; andR.sup.

Abstract: This invention concerns certain N-alkyl-N-[3-(alkoxyalkyl)phenyl]-2-haloacetamides having herbicidal activity, their preparation, and the control of weeds therewith.

Abstract: This invention provides as new compositions of matter 2,4,5-trichlorophenoxy acetic acid (2,4,5-T) and (2-2,4,5-trichlorophenoxy) propionic acid (Silvex) including the hydrolyzable salts, aliphatic esters and amides of these acids, which compositions are free of chlorinated dibenzo-p-dioxins.

Abstract: Disclosed are certain N-(2-cyanoalkoxy)methyl-N-(2-,3-, or 6-alkylphenyl)-.alpha.-haloacetamides having herbicidal activity, their mode of preparation and the use thereof to control weeds.

Abstract: This invention concerns certain substituted diphenyl ethers having herbicidal activity, their preparation, and the control of weeds therewith.

Abstract: Trichlorophenoxy alkanoic acid including hydrolyzable salts, aliphatic esters and amides thereof said compounds being free of chlorinated dibenzo-p-dioxins are prepared by liquid phase alkaline condensation of 3-chlorophenol or 3,4-dichlorophenol with an alpha halo alkanoic acid, ester or amide followed by liquid phase chlorination of the condensation product.

Abstract: This invention concerns certain substituted diphenyl ethers having herbicidal activity, their preparation, and the control of weeds therewith.

Abstract: This invention relates to herbicidally active diphenyl ether compounds, herbicidal compositions thereof and the control of weeds therewith, said compounds represented by the formula ##STR1## wherein A is: ##STR2## wherein: X is hydrogen or halogen;Y is hydrogen, halogen, cyano, trifluoromethyl, or alkyl containing up to 4 carbon atoms;Z is nitro, halogen, or cyano; andR and R.sup.1 are the same or different and represent hydrogen, halogen, or alkyl containing up to 10 carbon atoms, or R and R.sup.1 may join together to form a benzene ring.

Abstract: Disclosed are compounds, for example, methyl N-[5-(2-chloro-4-trifluoromethylphenoxy)-2-nitrobenzoyl]carbamate; the process of making the compounds; and the method of controlling weeds such as yellow foxtail and johnsongrass when growing among crops with the compounds represented by Formula I: ##STR1## wherein X is hydrogen (H), chloro (Cl), or bromo (Br); Z is nitro (NO.sub.2), halogen, or cyano (CN); and R is an alkyl of up to four carbon atoms or ##STR2## where A is halogen, an alkyl of up to three carbon atoms, an alkoxy of up to three carbon atoms, an alkylthio of up to three carbon atoms; cyano (CN), trifluoromethyl (CF.sub.3), nitro (NO.sub.2), or CO.sub.2 R.sup.2, where R.sup.2 is an alkyl of up to four carbon atoms, and n is an integer of 0, 1, 2, or 3.
