AI Technical Summary
Existing fungicides are not effective in controlling a variety of plant pathogenic fungi, especially against Fusarium graminearum and various resistant strains of wheat, and they also have the problem of drug resistance, making it difficult to meet the needs of comprehensive prevention and control.
Acetylhydrazine derivatives with phenyl heteroatom substituents were synthesized by reacting them in the presence of a condensing agent and an organic base to generate acetylhydrazine derivatives with broad-spectrum antifungal activity, which can be used to prepare plant fungicides.
It exhibits excellent broad-spectrum antifungal effects against fungi such as Fusarium graminearum, Sclerotinia sclerotiorum, Botrytis cinerea, Rhizoctonia solani, Alternaria alternata, Curvularia crescentis, Phytophthora capsici, and Sclerotium sclerotiorum, and also shows highly sensitive antifungal activity against drug-resistant strains such as resistant Fusarium graminearum.
