Abstract

The invention relates to a bactericidal composition containing thifluzamide and trifloxystrobin, wherein the weight ratio of thifluzamide to trifloxystrobin is (100:1)-(1:100), particularly (20:1)-(1:20). Compared with a single bactericide, the bactericidal composition disclosed by the invention has a significant synergistic effect on rice sheath blight diseases, rice blasts and false smuts, therefore, the bactericidal effect is improved, and the effect implemented by using the bactericidal composition is obviously higher than that implemented by using the single bactericide; the bactericide application cost is low, and the environmental pollution and bactericide residues are reduced; and action sites are increased, thereby being beneficial for overcoming and delaying the generation of pesticide resistance among germs. The bactericidal composition disclosed by the invention has no obvious adverse effect on test crops, and the leaf colors and growing of the test crops are normal, therefore, the bactericidal composition is good in safety, and accords with the security requirements on pesticide preparations.

Description

Technical field [0001] The present invention relates to an agricultural composition and an agricultural fungicide, in particular to an agricultural composition and an agricultural fungicide for preventing and controlling rice sheath blight, rice smut and rice blast. Background technique [0002] Rice sheath blight is an important disease in rice-producing areas. It is one of the three major rice diseases in my country. It occurs in all rice-producing areas across the country. It is more serious in the Yangtze River Basin and southern rice areas, especially in densely planted dwarf hybrid rice with high yields. Field occurrence is the most common and serious. Mainly caused by Rhizoctonia solani of the subphylum Deuteromycota, the disease spreads from bottom to top. In severe cases, it can reach the flag leaves and even the ears, causing large areas of lodging. In fields with severe disease, the yield is generally reduced by 5% to 10%, and in severe cases, the yield can be red...
