An agricultural or horticultural fungicide contains as an active ingredient thereof at least one compound selected from the group consisting of nitrogenated heterocyclic compounds represented by formula (I) (wherein, R represents a group represented by CRRRor a cyano group, Rto Rrepresent hydrogen atoms, alkyl groups or hydroxyl groups, or the like, Xrepresents a halogeno group or the like, m represents an integer of 0 to 5, Xrepresents a halogeno group or the like, n represents an integer of 0 to 3, B represents a carbon atom or a nitrogen atom, D represents a 5- to 7-membered hydrocarbon ring, and Ato Arepresent carbon atoms or nitrogen atoms, provided that Ato Ado not all represent carbon atoms when B represents a carbon atom) and salts thereof. 

Nitrogenated heterocyclic compound and agricultural or horticultural fungicide

The present invention provides a nitrogen-containing heterocyclic compound represented by formula (I) and salt thereof (wherein, Rto Reach independently represents a hydrogen atom, unsubstituted or substituted C1-20 alkyl group and the like, Rand R, Rand R, or Rand Rmay together form an unsubstituted or substituted 5- to 8-membered ring, A-B, in which A represents a carbon atom and B represents a nitrogen atom, represents the formula: C&#x2550;N and the like, Y represents an oxygen atom and the like, X and X' each independently represent an unsubstituted or substituted C1-20 alkyl group and the like, m represents an integer of 0 to 2, and n represents an integer of 0 to 4), and a fungicide for agricultural and horticultural use that contains at least one of these compounds as an active ingredient thereof, demonstrates reliable effects and can be used safely. The present invention further provides a boronic acid derivative that is a production intermediate of the aforementioned compounds, and a production method thereof.
