摘要：
The present invention provides a fungicidal composition and a fungicide for controlling asparagus stem blight, and belongs to the technical field of controlling asparagus stem blight. The composition includes difenoconazole and propamidine； and the weight ratio of the difenoconazole to the propamidine is 20:1-1:20. The fungicide of the present invention includes difenoconazole, propamidine and an auxiliary material； and the difenoconazole and propamidine account for 3%-90% by mass of the total amount of the fungicide. The present invention uses difenoconazole and propamidine as active ingredients, where a combined use of them has a synergistic effect on the pathogenic fungi of asparagus stem blight, and especially has an obvious synergistic effect on the asparagus stem blight in a ratio range of 20:1-1:20. In the present invention, a fungicide can be prepared as having a commonly-used agricultural dosage through a certain technical means, and the fungicide can provide an effective management tool for controlling of the asparagus stem blight.
