| abstract |
The invention relates to certain herbicidally active pyridine compounds, to agricultural compositions and to a method of using these pyridine compounds as herbicides. The disclosed compounds contain an effective amount of a compound of formula (I), wherein R1 represents Cl, Br, I, OCH3, OCHF2 or OCF3; R2 represents CN, CO2R4, CHO, C (X) NR17R18, C (S) OR6, C = CH, CHR19OR20, CH = NOR7 or CH = CR21R22; R3 represents n-propyl; C4-C10 alkyl, n-propyl or C4-C7 alkyl substituted with one or more halogens, OR8, SR9 or NR10R11; C1-C3 alkyl substituted with OR16, CO2 (C1-C2 alkyl) or phenyl optionally substituted with one or more CH3, CF3, OCH3, SCH3 or halogen; C3-C6 cycloalkyl; CH2 (C3-C6 cycloalkyl); phenyl optionally substituted with one or more CH3, CF3, OCH3, SCH3 or halogen; C2-C6 alkenyl optionally substituted with one or more halogens or CO2 (C1-C2 alkyl); OR12; SR13; or NR14R15; or their N-oxides or salts which can be used in agriculture. The invention also relates to herbicidal mixtures of these compounds with one or two other known herbicides. |
