Embodiment 1

[0028]In this example, ethyl maltol is used as a fungal antibacterial agent in the preparation of ethyl maltolite pesticides, including the following steps:

[0029](1) It is called 2 g of ethyl maltol, dissolved with 1000 ml double vapor, stirred evenly, and ethyl maltol solution;

[0030](2) Ethyl maltol solution at a temperature of 121 ° C, a pressure of 0.3 pp, 30 min, in plastic bottle, and an ethyl maltol plant pesticide.

[0031]Use: The amount of ethyl maltolite pesticide is 60 l / mu plant; the time interval of the ethyl maltolite pesticide spray is 7 days / time.

Embodiment 2

[0033]This example is an application of ethyl maltol as a fungal apronium in the preparation of a bacteriostatic ethyl maltol seed coating agent, including the following steps:

[0034](3) Weigh 0.2 g of ethyl maltol, dissolved with 100 ml of double vapor, stir evenly, and ethyl maltol solution;

[0035](4) The solution of the ethyl maltol in the temperature of 121 ° C, the pressure is 0.3 pp, 30 min, and inhibit the spray bottle, and the antibacterial agent ethyl maltol seed coating agent.

[0036]Using: The resulting inhibitor ethyl maltol seed coating agent was sprayed onto the seed in the amount of 400 ml / kg seeds, mixed uniform, flattened, 30 ° C to dry, ie the bacteriostatic ethyl maltol seed Seeds wrapped in coating.

Embodiment 3

[0038]The present embodiment is an application of ethyl maltophena as a fungibacterial agent in a traditional Chinese medicine liquid formulation: 30 min of ethyl maltol 2g, sterile ethyl maltol; then sterile ethyl maltol Uniformly mixed with 1000 ml of Chinese medicine liquid or semi-fluid solution, sterilized at 121 ° C for 30 min, potting, is obtained as an ethyl maltolol inhibitor such as a bacteriostactic agent.

[0039]Hereinafter, an Ethyl maltol plant pesticide trial, Example 2 Ethyl maltol seed coating agent trial and Example 3 An ethyl maltolicol in an antibiotic agent was added to the application effect test.

Abstract

The invention provides an application of ethyl maltol as a fungus inhibitor. According to the invention, ethyl maltol can serve as a fungus bacteriostatic agent to be applied to preparation of plant pesticides and plant seed coating agents, can also serve as the fungus bacteriostatic agent to be added into traditional Chinese medicine liquid preparations or semi-fluid preparations so as to effectively inhibit growth and reproduction of fungi including mould, can serve as a safe plant pesticide to reduce plant fungi diseases, inhibit mildewing and deterioration of seeds, reduce the mildewing and deterioration probability of the seeds or avoid the mildewing and deterioration of the seeds, and improve the seed germination rate, and can provide the inherent aroma enhancement function while integrating aroma enhancement, mildew prevention and corrosion prevention, enhance the stability of traditional Chinese medicine liquid preparations and semi-fluid preparations, replace or reduce the use of other toxic preservatives, reduce the use variety of additives, and reduce the potential safety risk of the additives, especially the preservatives.

Description

Technical field[0001]The present invention relates to an application of ethyl maltol, and more particularly to ethyl maltol as a fungal antibacterial agent, particularly as a fungal apronium in plant pesticide, seed coating, and traditional Chinese medicine hydrogens.Background technique[0002]Ethylmaltltol, chemical name 3-hydroxy-2-ethyl-4-pyridone, relative molecular mass 140.11, white crystalline powder, melting point 89-93 ° C, soluble in hot water. To date, it has always been one of the commonly used food gum additives that can be used for food. GB2760-2014 Food Safety National Standard - Food Additives Use Standard Appendix B.2.3 to synthesize the ethyl maltol collee as a combined fragrance (FEMA number: 3487). US food standards stipulate that ethyl maltol is 100 mg / L as a limited number of food fragrant agent (BATF-27CFR § 240.1051).[0003]At present, domestic plant pesticides are phenolic, aldehyde or antibiotics, and to inevitably bring toxicity and irritation while effect...
