[0002] Rice blast is caused by Phyricularia gisea, a fungus of the subdivision Ascomycetes. The pathogen is also called gray pear spore, and its sexual state is Magnaporthe grisea. This disease is one of the main factors that endanger the stable yield, high quality and safe production of rice in rice-growing areas around the world. When the damage is serious, it can lead to a 40% to 50% reduction in yield, or even a total crop failure.

[0003] For a long time, pesticide control has remained the fastest and most efficient measure for preventing and controlling rice blast. However, in rice production, due to the mutation of rice blast fungi and the irrational use of chemical agents, the problem of rice blast fungi's resistance to pesticides has become increasingly serious, resulting in a significant decrease in the field control effect of pesticides on rice blast. Therefore, new pesticides for rice blast control are urgently needed in rice production to provide a guarantee for the prevention and control of the disease.

[0004] The compounding of fungicides with different action mechanisms to develop new and efficient compound agents is of great significance for overcoming and delaying the resistance of pathogens, reducing the dosage of agents, effectively controlling the damage of rice blast, and ensuring stable and high yield of rice.
