Abstract

The invention discloses a pesticide composition with active ingredients being azoxystrobin and propamidine. The pesticide composition contains a commonly-used auxiliary agent, azoxystrobin and propamidine. Weight ratio of azoxystrobin to propamidine is 25:1-1:7. The total weight of azoxystrobin and propamidine in the pesticide composition is 1-85 wt%. After azoxystrobin and propamidine are compounded, the pesticide composition has an obvious synergistic effect, and dosage of the active ingredients of the compounded medicine is obviously reduced in comparison with dosage of each active ingredient which is used separately. The pesticide composition is applicable to control crop diseases caused by pathogenic fungi, especially crops' gray mold caused by Botrytis pathogen and crops' epidemic disease caused by Phytophthora pathogen.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing azoxystrobin and propamidine. Background technique [0002] Azoxystrobin, the English common name Azoxystrobin, is a methoxyacrylate fungicide. Azoxystrobin is a mitochondrial respiration inhibitor, which prevents electron transfer during cytochrome synthesis, and has protection, treatment, and leaf penetration. Efficient, broad-spectrum, against almost all fungal kingdoms (Ascomycotina, Basidiomycotina, Flagellate and Deuteromycotina) diseases such as powdery mildew, rust, glume blight, net spot, downy mildew It has good activity against disease, rice blast, etc. It can be used for stem and leaf spray, seed treatment, and soil treatment. [0003] Propamidine, English common name Propamidine, is an aromatic diamidine compound. Propamidine is a systemic fungicide, which can be absorbed, distributed and metabolized in plants, and has protective and ther...
