Abstract

The invention relates to an agricultural bactericidal composition, in particular to a bactericidal composition containing thifluzamide and fluoxastrobin. The weight ratio of the thifluzamide to the fluoxastrobin is 100:1-1:100. Compared with single pesticides, the bactericidal composition has synergetic effect on rice sheath blight and rice blast, and the bactericidal effect is improved; the cost of consuming bactericides is lowered, and environment pollution and pesticide residue are reduced; and bactericidal drug resistance can be overcome and delayed. The bactericidal composition has no evident adverse influence on test crops, leaves, growth and the like of the crops are all normal, the bactericidal composition is high in safety, meets the requirement of pesticide preparations on safety, and has well control effect on rice sheath blight and rice blast.

Description

technical field [0001] The invention relates to an agricultural bactericidal composition and a bactericide containing the bactericidal composition, in particular to a bactericidal composition for preventing and treating rice sheath blight and rice blast. Background technique [0002] Rice sheath blight is an important disease in rice production areas, and it is one of the three major diseases of rice in my country. It occurs in all rice production areas in the country, and it occurs more frequently in the Yangtze River Basin and southern rice areas. Occurrence is the most common and serious. It is mainly caused by Rhizoctonia solani, a fungus subphylum, and the disease spreads from bottom to top. When it is severe, it can affect the flag leaves and even the ears, and large areas will fall. Fields with severe disease generally reduce production by 5% to 10%, and can reach 50% to 70% in severe cases. With the popularization of dwarf multi-spike varieties, the increase of plan...
