THE INVENTION CONCERNS NEW DERIVATIVES OF PYRIDINE-3-CARBOXAMIDES. THESE DERIVATIVES OR THEIR SALTS ARE REPRESENTED BY GENERAL FORMULA I: (CF DRAWING IN BOPI) IN WHICH R IS A HYDROGEN ATOM, A PHENYL GROUP WHICH CAN BE FREELY SUBSTITUTED OR A GROUP - (CH) -R OR N IS A ENTIRE NUMBER FROM 1 TO 3 AND R IS A HYDROGEN ATOM OR A HYDROXY GROUP, LOWER ALCOXY, MERCAPTO, LOWER ALKYLTHIO, AMINO, DI (LOWER ALKYL) AMINO, CC ALKYL, ALKENYL OR ALKYLERALCYNYL 5, HYDROXYL OR ALKYLERALCYNYL 5 OR 6 CHAINONS OR PHENYL WHICH CAN BE SUBSTITUTED BY ONE OR TWO HALOGEN, ALKYL OR LOWER ALCOXY SUBSTITUTES; R AND R ARE DIFFERENT AND EACH REPRESENT AN ATOM OF HYDROGEN OR AN ALKYL GROUP IN CC, ALCENYL OR LOWER ALCYNYL, CYCLOALKYL, ALCOXYALKYL OR ALKYLTHIOALKYL LOWER PHENYLE LOWER AND SUBSEQUENTLY SUBSTITUTE LOWER PHENYLE AND SUBSTITUTE LESS THAN LESS THAN LOWER PHENYLU, OR SUBSTITUTE LESS THAN LOWER PHENYL. OF HALOGEN, LOWER ALKYL OR LOWER ALCOXY, 5 OR 6 CHAIN HALOGENALKYL OR HETEROCYCLIC TYPE; R, R, AND R, IDENTICAL OR DIFFERENT, EACH REPRESENTS A HYDROGEN ATOM, A HALOGEN ATOM OR A CYANO, NITRO, AMINO, LOWER ALKYL, LOWER HALOGEN-ALKYL, HYDROXY, ALCOXY ARBOXY INFERIE, (LOWER ALCOXY) CARBONYL; R IS A HYDROGEN ATOM OR A LOWER ALKYL GROUP, A PHENYL WHICH CAN BE FREELY SUBSTITUTE OR ARALKYL WHICH CAN BE FREELY SUBSTITUTED; OR R AND R CAN BE COMBINED TO FORM A GROUP - (CH) - M IS 3 OR 4). THESE DERIVATIVES ARE ESPECIALLY ENJOYABLE OF PLANT GROWTH INHIBITION ACTIVITIES. FIELD OF APPLICATION: HERBICIDES. |
