Conventional many fungicidal compositions have had practical problems such that either a preventive effect or a curing effect is inadequate, the residual effect tends to be inadequate, or the controlling effect against plant diseases tends to be inadequate depending upon the application site, and a fungicidal composition to overcome such problems has been desired. The present invention provides a fungicidal composition containing an acid amide derivative of the formula (I) or a salt thereof, as an active ingredient:
wherein A is phenyl which may be substituted, benzyl which may be substituted, naphthyl which may be substituted, heterocyclic ring which may be substituted, fused heterocyclic ring which may be substituted, or the like; B is heterocyclic ring which may be substituted, fused heterocyclic ring which may be substituted, or naphthyl which may be substituted; each of R
1
and R
2
which are independent of each other, is alkyl, or the like; R
3
is hydrogen, or the like; each of W
1
and W
2
which are independent of each other, is oxygen or sulfur.
传统的许多杀菌组合物存在实际问题,例如预防效果或治疗效果不足,残留效果倾向于不足,或者根据应用场所,对植物疾病的控制效果倾向于不足,因此需要一种克服这些问题的杀菌组合物。本发明提供了一种含有式(I)的酸
