preparation example Construction

[0034] A kind of preparation method comprising the azoxystrobin suspension concentrate of safener, comprises the following steps:

[0035] (1) Weigh the following raw materials according to the amount: azoxystrobin original drug, wetting agent, dispersant, defoamer, and add water to 60% of the total amount, stir them for 0.5-1h, and mix well;

[0036] (2) Grinding the above-mentioned mixed components in a sand mill, and grinding to an average particle size of 3-6 μm after 2-4 hours, to obtain the initial product of the suspension;

[0037] (3) Mix the thickener, antifreeze, and water to 5% of the total amount, and add it to the primary product of the suspending agent. After stirring for 1-2 hours at a speed of 1000r / min, the secondary product of the suspending agent is obtained. .

[0038] (4) Mix the safener and water to 35% of the total amount, and add it to the secondary product of the suspending agent, and stir it with a mixer at a speed of 1000r / min for 1-2 hours to obta...

Abstract

The invention provides a safe azoxystrobin suspension agent which is characterized by comprising azoxystrobin, an auxiliary, a safener and bacterial cellulose fibers. The safe azoxystrobin suspensionagent is prepared by compounding the azoxystrobin, the auxiliary, the safener and the bacterial cellulose fibers, has the characteristics of being safe to flowers, leaves and fruits of apple trees andthe like and has better prevention and treatment effects on apple scab.

Description

technical field [0001] The invention relates to a pesticide fungicide and its application, in particular to a safe azoxystrobin suspension, its preparation method and its application. Background technique [0002] Azoxystrobin is a methoxyacrylate fungicidal pesticide with high efficiency and broad spectrum. It is effective against almost all diseases of the fungal kingdom (Ascomycotina, Basidiomycotina, Flagellate and Deuteromycotina). activity, and azoxystrobin is systemic and can flow in the leaves so that it can be effectively transferred to new leaves. For these reasons, azoxystrobin is widely used in stem and leaf treatment and leaf spraying. The extensive development and application of azoxystrobin has brought tangible benefits in disease prevention and control to agricultural production. [0003] The growth cycle of apple trees is vulnerable to powdery mildew, rust, leaf spot, black spot, red spot, etc., and azoxystrobin has a good preventive and therapeutic effect ...
