Abstract

The invention relates to a pesticide composition and particularly relates to a sterilization composition which is used for controlling powdery mildew, anthracnose, late blight, brown blotch and banded sclerotial blight in agriculture. The sterilization composition contains active ingredients including difenodiconazole and pyraclostrobin. Compared with the single preparation, the sterilization composition has an obvious synergistic effect on agricultural diseases and is beneficial to overcoming and delaying the production of bacteria resistance.

Description

【Technical field】 [0001] The invention relates to a pesticide composition, in particular to a bactericidal composition, in particular to a bactericidal composition for preventing and controlling powdery mildew, anthracnose, late blight, brown spot and sheath blight in agriculture. 【Background technique】 [0002] Powdery mildew and anthracnose are very important diseases on fruits, vegetables and other crops, often causing important losses of crops. Late blight is one of the major diseases on tomatoes and potatoes. Peanut brown spot disease caused by fungus Cercospora arachidicola Hori of Deuteromycotina can damage peanut leaves, petioles and stems. Sheath blight is the main disease of rice and wheat, and it occurs seriously all year round, mainly damaging the sheaths and leaves. [0003] Pyraclostrobin (English common name: Pyraclostrobin), also known as pyraclostrobin, chemical name: N-{2-[1-(4-chlorophenyl)-1H-pyrazol-3-yloxymethyl ] phenyl} (N-methoxy) methyl carbamate...
