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.
提供 3-
苯甲酰基-
2,4,5-取代的
吡啶衍生物或它们的盐、含有它们的
杀菌剂以及生产它们的
中间体。
通过提供由特定的 3-
苯甲酰基-
2,4,5-取代的
吡啶衍生物或其盐组成的一组化合物,或含有它们的杀真菌剂,它们具有所谓的耐雨性,即即使在施用药剂后作物受到降雨的影响,它们也能表现出优异的效果,因此无需考虑施用药剂后的降雨情况而增加施用次数或药剂剂量。因此,可以用较低的成本和较少的劳动力保护作物免受病害的伤害。
