(57) [Summary] (Modified) [Structure] Formula (1) (wherein R 1 represents a hydrogen atom, a lower alkyl group or an aralkyl group, R 2 and R 3 are each independently a hydrogen atom, It represents a lower alkyl group or a cyano group, and R 4 and R 5 are each independently a hydrogen atom, a lower alkyl group, a lower alkoxy group, an amino group, a lower alkyl group-substituted amino group, a nitro group, a cyano group, a halogen atom, a halogen-substituted group. It represents a lower alkyl group or a halogen-substituted lower alkoxy group. Also, R 1 and R 4 , R 2 and R 3 , R 2 and R 4 or R 4 and R 5 can also form a ring together. ) 2,6-dichloroisonicotinic acid benzylamide derivative and a plant disease controlling agent containing the same. [Effect] It has an excellent effect in controlling various plant diseases caused by plant pathogenic viruses, bacteria, and filamentous fungi, especially rice blast, and there is no concern about chemical damage. |
