摘要

Compounds of Formula 1, and their N -oxides and agriculturally suitable salts, are disclosed as useful as fungicides (INSERT FORMULA I HERE) wherein R<SUP>1</SUP> is<SUP/>NR<SUP>4</SUP>R<SUP>5</SUP>, N=CR<SUP>19</SUP>R<SUP>21</SUP>, OR<SUP>6</SUP>, G<SUP>1</SUP> or G<SUP>2</SUP>; or C<SUB>1</SUB>-C<SUB>8</SUB> alkyl, C<SUB>2</SUB>-C<SUB>8</SUB> alkenyl, each optionally substituted; A is O, S or NR<SUP>7</SUP>; R<SUP>2</SUP> is cyano, NR<SUP>8</SUP> N=CR<SUP>9</SUP>R<SUP>10</SUP>, NC(=O)R<SUP>30</SUP>; or a 5- or 6-membered heteroaromatic ring, each ring or ring system optionally substituted; R¿3? is H, halogen, cyano, C<SUB>1</SUB>-C<SUB>6</SUB> alkyl; J is C<SUB>1</SUB>-C<SUB>8</SUB> alkyl or phenyl, optionally substituted; and R<SUP>4</SUP>, R<SUP>5</SUP>, R<SUP>6</SUP>, R<SUP>7</SUP>, R<SUP>8</SUP>, R<SUP>9</SUP>, R<SUP>10</SUP>, R<SUP>19</SUP>, R<SUP>21</SUP>, R<SUP>30</SUP>, G<SUP>1</SUP> and G<SUP>2</SUP> are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula 1 and a method for controlling plant diseases caused by fungal plant pathogens which involves applying an effective amount of a compound of Formula 1.
