<p>This invention relates to certain novel substituted 2,6-dinitroaniline compounds of formula (I) wherein R2 is sec-alkyl C3-C7; monochloro-sec-alkyl C3-C4 or methoxy-sec-alkyl C3-C4; Z is -CHR3OCH3, R3 being hydrogen or-CH3 and Y is chloro or alkyl selected from the group consisting of -CH3, -C2H5, n-Pr, i-Pr, sec-Bu and i-Bu, and compounds of formula (I) selected from the group wherein: z is -CH3; and R2 and Y respectively are -CH(C2H5)2 and i-Pr or -CH(C2H5)2 and -C2H5 or -CH(C2H5)2 and sec-Bu or -CH(C2H5)2 and n-Pr or-CH(C2H5)2 and n-Bu or i-Pr and -C2H5 or sec-Bu and -C2H5 or i-Pr and i-Pr or i-Pr and n-Pr or sec-Bu and i-Pr or -CH(C2H5)-CH2Cl and -Cl or sec-Bu and n-Pr and compounds of formula (I) selected from the group wherein: R2 is i-C4H9 or n-Pr, Z is-CH2OCH3 and Y is i-Pr or -CH3 or -C2H5; R2 is -CH(C2H5)2, Y is n-Bu and Z is CH2OCH3; or R2 is n-Bu, Z is -CH2OCH3 and Y is i-Pr; R2 is i-Pr, Z is -CH2OCH3 and Y is n-C4H9; R2 is CH(C2H5)2, Z is CH2OC2H5 and Y is CH3. It further relates to certain novel preemergence herbicidal methods and compositions employing substituted 2,6-dinitroaniline compounds.</p> |
