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
吡啶衍生物或其盐,含有它们的杀菌剂以及用于生产它们的中间体。通过提供一组化合物,其中包括特定的3-苯甲酰基-2,4,5-取代
吡啶衍生物或其盐,或含有它们的杀菌剂,这些化合物具有所谓的雨
水稳定性,即使作物在
化学品施用后遭受降雨,它们仍能展现出优异的效果,因此不必考虑
化学品施用后的降雨增加
化学品的施用次数或剂量。因此,可以以更低的成本和更少的劳动力保护作物免受病害的伤害。
