Embodiment 1

[0040] Embodiment 1: the antibacterial activity experiment of 5 kinds of complexes

[0041] Test agents: 5 kinds of glycolate complex fungicides;

[0042] Pathogens tested: Bacterial spot of rice.

[0043] Test method: tube-and-disc method. Make the concentration of 50ppm solution with sterilized water for the test agent, set sterilized water as blank control group in addition, parallel test 3 times; use sterilized tweezers to clamp the Oxford cup and place it evenly on the surface of the culture plate containing bacteria (concentration of bacteria for 10 6 ~10 8 cfu / ml), inject 0.1ml of the test agent into the cup, and culture it at a suitable temperature for 1 day; take out the culture medium, measure the diameter of the antibacterial zone by the cross method, and measure the diameter of the antibacterial zone by the presence or absence of the antibacterial zone and the size of the antibacterial zone To evaluate its bactericidal activity. The experimental results are as...

Embodiment 2

[0048] Embodiment 2: 20% copper glycolate complex (II) suspension concentrate (SC) (A)

[0049]20% copper glycolate complex, 4% ethylene glycol dibutyl ether, 3% sodium dodecylbenzenesulfonate, 0.5% magnesium aluminum silicate, 0.3% xanthan gum, 0.5% kasone, ethylene glycol 4%, mixed with 0.2% silicone defoamer, add water to the total weight of 90%; after high-speed dispersion, sand mill for 2 hours with a speed of 2500r / min, until the particle size of the dispersed original drug reaches the design requirement of 2-10μm ;Put the sanded material into the open cup, carry out high shear, add the thickener and the remaining amount of water under stirring, and shear until the viscosity reaches the design requirement of 300-1000mpa.s; the material can be discharged . Test the suspension rate, heat storage stability and low temperature stability of the final product to confirm that its quality indicators fully meet the requirements shown in the table below.

Embodiment 3

[0052] Embodiment 3: Water-soluble granules (SG) (B) of 20% copper glycolate complex (II)

[0053] Mix 200g of copper glycolate, 10g of white sugar, 50g of potassium dihydrogen phosphate, and 100g of sodium dodecylbenzenesulfonate, and make up 1000g of soluble starch; stir until fully mixed, then pulverize to a particle size of less than 44μm, add 200g of water, and use Gravity granulation and drying to obtain 20% copper glycolate complex water-soluble granules.

Abstract

The invention belongs to the field of agricultural sterilizing agents, and particularly relates to a glycollate complex sterilizing agent and application thereof. The effective components of the sterilizing agent is a zinc glycolate complex or a copper glycolate complex, and the mass fraction of the effective components of the sterilizing agent is 0.5%-90%, and is 20%-50% preferably; the sterilizing agent is prepared into powder, a suspending agent or granules according nto difference of physicochemical properties of the effective components. The sterilizing agent is applied to plant diseasesincluding a streak disease, angular leaf spots, brown spots, ralstonia solanacearum and the like which are caused by infection of pseudomonas and bacterial diseases such as leaf blight and canker which are caused by xanthomonas campestris. The sterilizing agent is easy to adhere, easy to absorb, remarkable in sterilizing effect, high in utilization rate and good in biological compatibility, and isquite environmentally friendly; and the sterilizing agent is effective to bacterial diseases and a fungous disease, and is wide in application range, convenient to apply and quite wide in applicationprospect.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to glycolate complex fungicides and applications thereof. Background technique [0002] Glycolic acid, also known as glycolic acid and glycolic acid, is the simplest a-hydroxy acid. The raw material is a slightly white hygroscopic crystal, odorless, has a certain metal complexing ability, good permeability, and has good cleaning and sterilization It has a wide range of sources and is currently mainly used as a cleaning agent. It is widely used in industrial fields such as leather, oil and gas, washing, and prevention, as well as in medical fields. [0003] Zinc ions have both fungicidal and bactericidal effects. The zinc ions in the drug and the cations (H + , K + etc.) exchange, causing the protein on the cell membrane of the bacteria to coagulate and kill the bacteria; some zinc ions penetrate into the cells of the bacteria, combine with certain enzymes, affect their acti...
