  The invention relates to new 2-phenyl-4-pyrone derivatives which can be used in agriculture. They correspond to the general formula: ##STR1## in which X.sub.1 and X.sub.2, which are identical or different, each represent a hydrogen or halogen atom, with the proviso that at least one of these substituents represents a halogen atom, R.sub.1 represents an alkoxy radical (C.sub.1 -C.sub.4), an alkenyloxy radical containing from 2 to 4 carbon atoms, a propargyloxy radical, a halogenoalkoxy radical (C.sub.1 -C.sub.4), an amino radical, an alkylamino radical (C.sub.1 -C.sub.4) or a dialkylamino radical in which each of the alkyl parts, which are identical or different, contains from 1 to 4 carbon atoms, R.sub.2 represents a halogen atom, an alkyl radical containing from 1 to 5 carbon atoms, an alkoxy radical (C.sub.1 -C.sub.4), an alkenyloxy radical (C.sub.3 -C.sub.4), an alkynyloxy radical (C.sub.3 -C.sub.4), an alkylthio radical (C.sub.1 -C.sub.4), a halogenoalkyl radical (C.sub.1 -C.sub.4), a halogenoalkoxy radical (C.sub.1 -C.sub.4), a halogenoalkylthio radical (C.sub.1 -C.sub.4) or the nitro, hydroxyl or cyano radical and n is an integer which can be equal to 0, 1, 2, 3, 4 or 5, it being understood that, if n is greater than or equal to 2, the substituents R.sub.2 can be identical or different. They can be used for protecting plants against fungal diseases.

  本发明涉及新的2-苯基-4-吡喃酮衍生物，可用于农业。它们对应于以下通式：##STR1## 其中X.sub.1和X.sub.2，相同或不同，每个代表氢或卤素原子，但至少其中一个取代基代表卤素原子，R.sub.1代表醇基（C.sub.1-C.sub.4），含2至4个碳原子的烯氧基，丙炔氧基，卤代烷氧基（C.sub.1-C.sub.4），氨基，烷基氨基（C.sub.1-C.sub.4）或双烷基氨基基，其中每个烷基部分相同或不同，含有1至4个碳原子，R.sub.2代表卤素原子，含1至5个碳原子的烷基，醇基（C.sub.1-C.sub.4），烯氧基（C.sub.3-C.sub.4），炔氧基（C.sub.3-C.sub.4），硫代烷基（C.sub.1-C.sub.4），卤代烷基（C.sub.1-C.sub.4），卤代烷氧基（C.sub.1-C.sub.4），卤代烷基硫基（C.sub.1-C.sub.4）或硝基，羟基或氰基，n是一个整数，可以等于0,1,2,3,4或5，如果n大于或等于2，则了解到取代基R.sub.2可以相同或不同。它们可用于保护植物免受真菌病害的影响。
