Embodiment 1

[0018] A bactericidal suspension containing tetramycin and azoxystrobin, the active ingredient of which is a binary compound of tetramycin and azoxystrobin, including the following components in terms of mass fraction: 10 parts of tetramycin ; 5 parts of azoxystrobin; 10 parts of dispersant; 2 parts of antifreeze; 0.5 parts of thickener; 0.5 parts of defoamer; 2 parts of penetration enhancer;

[0019] First mix other additives, mix evenly through high-speed shearing, add the active ingredients tetramycin and azoxystrobin, and grind in a sand mill for 2 to 3 hours, so that the particle diameter is less than 5mm, and the present invention can be produced. Suspension formulations of the compositions.

Embodiment 2

[0020] Example 2: Toxicity test of different ratios of tetramycin and azoxystrobin.

[0021] 1.1 Test target

[0022] It was collected and isolated from potted cucumbers of the same type that had never been treated with tetramycin and azoxystrobin in Taizhou, Zhejiang Province. The cucumber variety for testing was Changchun Mici.

Abstract

The invention relates to the technical field of combination of pesticides and particularly relates to a sterilization suspension agent containing tetramycin and azoxystrobin and a preparation method thereof. According to the sterilization suspension agent containing tetramycin and azoxystrobin, the effective components, namely tetramycin and azoxystrobin, of the sterilization suspension agent are subjected to binary compounding; and the sterilization suspension agent comprises the following components in parts by mass: 1-50 parts of tetramycin, 1-50 parts of azoxystrobin, 5-20 parts of a dispersant, 1-5 parts of an anti-freezing agent, 0.1-2 parts of a thickening agent, 0.1-0.8 part of a de-foaming agent, 0-10 parts of a penetration enhancer, 0.1-5 parts of a pH value regulator and the balance of water. The compound sterilization agent, which takes tetramycin and azoxystrobin as effective components, has an obvious synergistic effect and can delay the generation of vital drug resistance; and the production cost and the use cost are lowered, and the sterilization suspension agent can be used for treating resisting diseases.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a fungicidal suspension containing tetramycin and azoxystrobin and a preparation method thereof. Background technique [0002] Tetramycin (Wuningmycin) is a fermentation metabolite of Streptomyces nonhygroscopicus subsp. Fungi have a strong killing effect. It is suitable for the prevention and control of various fungal and bacterial diseases of various crops. Especially for fruit tree rot spot leaf spot disease; rice blast; soybean root rot; melon wilt; cotton verticillium wilt; jujube rust; grape white rot; ginseng Panax notoginseng black spot; It has special effects on fungal diseases such as disease, canker, gummosis, defoliation, and blight of forest seedlings. [0003] Azoxystrobin is a high-efficiency, broad-spectrum, new-type fungicide, which has multiple functions such as systemic conduction, prevention, protection, and treatment, and can inhibit almost a...
