Problems solved by technology

Therefore, in the main hickory producing areas such as Lin'an City, Zhejiang Province, in recent years, some people have used the outer peel of hickory nuts to make stick-shaped charcoal to solve the pollution. The economic benefits of this method are not good.
Studies have shown that hickory nut exocarp contains organic substances such as alkaloids, phenolic compounds, tannins, saponins, steroids and anthraquinones. Information report on the production of pesticides from the exocarp of hickory nuts and the release of related products

Embodiment 1

[0026] Example 1: The pecan exocarp was dried to a water content of 9%, crushed into a 50-mesh powder, and weighed 500 kg of crushed matter; extracted with 1500 kg of methanol in a reflux extraction kettle at a temperature of 70° C. for 8 hours, and centrifuged to obtain The extract is then vacuum-concentrated until the concentrated solution is close to 500kg, and then 500kg of the extract is obtained for subsequent use.

[0027] According to the raw materials corresponding to Example 1 in Table 1 and the proportions by weight thereof, bactericide emulsifiable concentrate or microemulsion bactericide were respectively prepared.

[0028] Example 1 in comparison table 1 prepares fungicide emulsifiable concentrate: with the extract of 80kg above-mentioned making, 50kg methyl alcohol, 20kg calcium laurate, 50kg deionized water, first three are joined in 50kg deionized water earlier, constant temperature Stir for 1h and serve.

[0029] Example 1 in contrast table 1 prepares microe...

Embodiment 2

[0030] Embodiment 2: the hickory nut exocarp is dried to a moisture content of 10%, is ground into 40 order powder, and weighs 500 kg of pulverized matter; with ethanol 1500 kg, extracts under 75 ℃ of temperature conditions, all the other are identical with embodiment 1 method, Concentrate at last to obtain 500kg of extract for subsequent use. Contrast the corresponding raw material of Example 2 in Table 1 and the weight parts thereof respectively with the method (high-speed stirring, temperature 40 ℃) identical with Example 1 to prepare bactericide emulsifiable concentrate or microemulsion bactericide.

Embodiment 3

[0031] Embodiment 3: the pecan exocarp is dried to a moisture content of 7%, crushed into 60 mesh powder, and weighed to obtain 1000kg of pulverized matter; 3000kg of ethyl acetate is used as an extraction solvent, extracted at a temperature of 80°C, and the rest are carried out Example 1 method is the same, finally concentrated to obtain 1000kg stock solution of extract for subsequent use. Contrast the raw materials corresponding to Example 3 in Table 1 and the proportioning by weight thereof, and use the same method as Example 1 (high-speed stirring, temperature 50° C.) to prepare bactericide emulsifiable concentrate or microemulsion bactericide.

[0032] With the above-mentioned three embodiments, the remaining five embodiments can be deduced according to the proportions in Table 1, and will not be listed one by one.

[0033] When preparing the extract, in addition to selecting a good extraction solvent from factors such as cost and the performance of dissolving effective s...

Abstract

The present invention relates to a hickory nutshell germicide and its production method. Said production method includes the following steps: drying and pulverizing, reflux dissolving, centrifugal separation and vacuum concentration so as to obtain extract, then using (by weight portion) 30-80 portions of the above-mentioned extract, 20-50 portions of solvent and 10-20 portions of adjuvant so as to obtain the germicide emulsifiable concentrate or using 20-40 portions of the above-mentioned extract, 10-20 portions of solvent, 10-20 portions of adjuvant and 30-50 portions of deionized water to prepare germicide microemulsion. Said germicide can be used for effectively killing several plant disease-producing germs of cucumber anthrax bacteria, apple putrescence disease-producing germ and banded sclerotial blight of rice plant, etc.

Description

technical field [0001] The invention relates to a botanical pesticide and a production method thereof, in particular to a fungicide using hickory exocarp as a raw material and a production method thereof. Background technique [0002] Hickory nut (Carya cathayensis Sarg.) belongs to the Juglandaceae (Juglandaceae) hickory (Carya Nutt.) plant, and my country's Zhejiang and Anhui provinces are widely distributed. Hickory nuts are covered with pericarp. For many years, the place of production has been discarded as waste, piled up and rotted, causing damage to vegetation and polluting water quality. Therefore, in the main hickory producing areas such as Lin'an City, Zhejiang Province, in recent years, some people have made stick-shaped charcoal from the outer skin of hickory nuts to solve the pollution. The economic benefits of this method are not good. Studies have shown that the pecan exocarp contains organic substances such as alkaloids, phenolic compounds, tannins, saponins...
