Problems solved by technology

[0003] However, kasugamycin itself is prone to decompose, and copper quinolate is an organic copper chelate, free copper ions will promote the decomposition of kasugamycin, thereby reducing the efficacy of kasugamycin, and copper quinolate The powder is easy to agglomerate under high temperature environment, which will cause the creaming and even curing of kasugamycin and copper quinolate, which will further reduce the efficacy of kasugamycin and copper quinolate

preparation example Construction

[0058] The present application also provides a preparation method of a suspension containing kasugamycin and copper quinolate, which is used to prepare the suspension containing kasugamycin and copper quinolate in any of the above embodiments. The preparation method of the suspending agent containing kasugamycin and copper quinoline comprises part or all of the following steps: placing the short-chain dispersant and copper quinoline in water for primary mixing operation to obtain a primary mixed solution; dispersing the long-chain agent, wetting agent, pH regulator and primary mixed solution to perform secondary mixing operation to obtain secondary mixed solution; to perform tertiary mixing operation on kasugamycin, grinding aid medium and secondary mixed solution to obtain the mixture to be ground; Grinding the mixture to be grinded to obtain a suspension containing kasugamycin and copper quinoline.

[0059] In the preparation method of the above-mentioned suspending agent co...

Embodiment 1

[0075] Put 2.3kg RD-95 and 10kg quinoline copper into 77kg water and stir and mix to obtain quinoline copper solution, the stirring speed is 1450r / min, and the stirring time is 30min;

[0076] Add 0.7kg of lignin Reax 910, 1kg of B600, 1kg of 4075 and 0.5kg of lactic acid into the quinoline copper solution for stirring and mixing, the stirring speed is 1450r / min, and the stirring time is 30min;

[0077] Then add 1 kg of kasugamycin, 5 kg of ethylene glycol, 1 kg of LT-908 and 0.5 kg of magnesium aluminum silicate to the quinoline copper solution for stirring and mixing to obtain a mixed solution to be ground. The stirring speed is 1450 r / min, and the stirring time is 30 min;

[0078] The mixed solution to be ground is placed in a grinder and ground to D98≤1 μm to obtain a suspension containing kasugamycin and copper quinolate.

Embodiment 2

[0080] 2.8kg FD and 18kg quinoline copper were placed in 66kg water and stirred and mixed to obtain quinoline copper solution, the stirring speed was 1500r / min, and the stirring time was 40min;

[0081] Add 1.2kg of lignin G-NA, 2kg of 4075, 1kg of MORWET-EFW and 1kg of citric acid into the quinoline copper solution for stirring and mixing, the stirring speed is 1500r / min, and the stirring time is 40min;

[0082] Then add 2kg kasugamycin, 5kg ethylene glycol, 0.8kg LT-908 and 0.2kg titanium dioxide into the quinoline copper solution and stir and mix to obtain a mixed solution to be ground. The stirring speed is 1450r / min, and the stirring time is 40min;

[0083] The mixed solution to be ground is placed in a grinder and ground to D98≤1 μm to obtain a suspension containing kasugamycin and copper quinolate.

Abstract

The invention provides a suspending agent containing kasugamycin and oxine-copper and a preparation method thereof. The suspending agent containing kasugamycin and oxine-copper comprises the following components in parts by mass: 1-5 parts of kasugamycin; 10-40 parts of oxine-copper; 0.5-3 parts of a pH regulator; 3-8 parts of dispersing agents; 3-6 parts of a wetting agent; 0.5-2 parts of a grinding aid medium; and 30-79 parts of water. The dispersing agents comprise a long-chain dispersing agent and a short-chain dispersing agent. The suspending agent containing kasugamycin and oxine-copper can effectively improve the pesticide effects of kasugamycin and oxine-copper.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a suspension containing kasugamycin and copper quinolate and a preparation method thereof. Background technique [0002] Kasugamycin is a metabolite of microorganisms, has strong permeability and systemic properties, has preventive and therapeutic effects, and is highly effective, long-lasting, and non-mutagenic, teratogenic, and carcinogenic. Copper quinoline is a quinoline protective low-toxic fungicide with low residue and safe use. It has good preventive and therapeutic effects on fungal and bacterial diseases. After spraying, it can form a tight layer on the surface of plants. The protective medicinal film has a strong affinity with plants, is resistant to rain erosion, and can effectively inhibit the germination and invasion of germs, so as to achieve the purpose of disease prevention and treatment. The combination of the two can not only expand the applicat...
