3-BENZOYL-2,4,5-SUBSTITUTED PYRIDINE DERIVATIVES OR SALTS THEREOF AND BACTERICIDES CONTAINING THE SAME

摘要

To provide 3-benzoyl-2,4,5-substituted pyridine derivatives or their salts, fungicides containing them, and intermediates for producing them. <??>By providing a group of compounds comprising specific 3-benzoyl-2,4,5-substituted pyridine derivatives or their salts, or fungicides containing them, which have so-called rainfastness, whereby they are capable of exhibiting excellent effects even when crops have received rainfall after application of the chemicals, it becomes unnecessary to increase the number of applications or the dose of the chemicals by taking into consideration the rainfall after the application of the chemicals. Thus, it is possible to protect crops from disease injuries at a lower cost with less labor.
