Embodiment 1

[0061] Formulation Example 1: 15% wettable powder

[0062] Raw material dosage (parts by weight)

[0063] Gallic Tannin 15

[0064] White carbon black 5

[0065] Sodium dodecylbenzene sulfonate 5

[0066] Light calcium carbonate 75

[0067] Firstly, light calcium carbonate is pre-pulverized, and then it is thoroughly mixed with the above-mentioned gallic tannins, white carbon black (produced by Shanghai Yimeng Chemical Co., Ltd.) and sodium dodecylbenzene sulfonate (produced by Shanghai Shengzhong Chemical Co., Ltd.). Then it is processed by jet pulverization to obtain the 15% wettable powder.

Embodiment 2

[0068] Formulation Example 2: 40% water suspension

[0069] Raw material dosage (parts by weight)

[0070] Gallic Tannin 40

[0071] Ethylene glycol 10

[0072] Fatty alcohol polyoxyethylene ether sodium sulfate 10

[0073] Water 40

[0074] Weigh out the gallic tannins, add water, ethylene glycol and fatty alcohol polyoxyethylene ether sodium sulfate (produced by Dezhou Aifa Chemical Co., Ltd.), and process the ball milling and sand milling to prepare the 40% aqueous suspension emulsion.

Embodiment 3

[0075] Formulation Example 3: 20% oil suspension

[0076] Raw material dosage (parts by weight)

[0077] Gallic Tannin 20

[0078] Dimethyl phthalate 20

[0079] Fatty alcohol polyoxyethylene ether sodium sulfate 10

[0080] Mineral oil 50

[0081] Weigh out the gallbladder tannins, add mineral oil and dimethyl phthalate (produced by Shijiazhuang Bailong Chemical Co., Ltd.) and fatty alcohol polyoxyethylene ether sodium sulfate (produced by Dezhou Aifa Chemical Co., Ltd.), and then go through ball milling and sanding. Grinding treatment, the 20% oil suspension emulsion is prepared.

Abstract

The invention relates to the application of gallnut extract as the antiseptic and antiseptic containing the gallnut extract. The gallnut extract mainly comprises at least one of the following extracted compounds: Chinese tannin, five gallanilide glucose (1, 2, 3, 4 and 6-Five-O- gallanilide-Beta-D-glucose) and multiply gallanilide glucose (Six or Seven to twevel gallanilide glucose). The invention has good effects for preventing and curing a plurality of crop diseases and is good for environment, which is characterized by low residue, high prevention effect, a plurality of action points and difficulty of generating drug resistance for germina.

Description

【Technical Field】 [0001] The present invention relates to the application of gallnut extract as a fungicide, and to an agricultural fungicide containing the gallnut extract as an active ingredient. 【Background technique】 [0002] Plant diseases are an important factor in crop yield reduction. For this reason, a large amount of pesticides need to be applied for disease prevention and control every year to restore crop yield losses. In recent years, the damage caused by diseases to crops has been aggravated. Due to the abuse of pesticides, pathogens have become more and more resistant to pesticides, causing the prevention and control effects to decrease year by year. At the same time, due to the excessive amount of pesticides, it has caused a certain degree of pollution to the environment. . Therefore, there is an urgent need to develop pesticide varieties with better disease control effects and environmental compatibility. [0003] Applying plant extracts that can effectively cont...
