Problems solved by technology

There have been reports on the use of bayberry branch and leaf extracts as antioxidants for food preservation, but there are no reports and products about the preparation of pesticides.
In addition, bayberry production areas need to be pruned every year, a large number of branches and leaves are used as firewood or burned on the spot, and a large number of resources have not been effectively used

Embodiment 1

[0030] Embodiment 1: drying waxberry branches and leaves to a moisture content of 10%, pulverizing them into 30 mesh powders, weighing 100kg of pulverized objects; using 300kg of methanol, extracting at a temperature of 50°C for 12h in a reflux extraction kettle, and obtaining after centrifugation Extraction; then carry out vacuum concentration until the concentrated solution is close to 100kg and end to obtain 100kg of extract for subsequent use.

[0031] According to the raw materials corresponding to Example 1 in Table 1 and the proportions by weight thereof, bactericide emulsifiable concentrate or bactericide microemulsion were respectively prepared. Specific instructions are given below:

[0032] Prepare fungicide emulsifiable concentrate according to Example 1 in Table 1: Add 80kg of the above-mentioned extract, 50kg of methanol, and 20kg of calcium laurate into the reaction kettle in turn, and stir evenly.

[0033] Example 1 in contrast table 1 prepares bactericide mic...

Embodiment 2

[0034] Embodiment 2: dry the branches and leaves of Myrica rubra to a water content of 8%, pulverize into 40 mesh powder, and weigh 80kg of pulverized matter; use 240kg of ethanol to extract at a temperature of 60°C, and the rest are the same as in Example 1, and finally concentrated Get 80kg of extract for subsequent use. Contrast the corresponding raw materials of Example 2 in Table 1 and the parts by weight thereof respectively with the same method as Example 1 (high-speed stirring temperature 50° C.) to prepare bactericide emulsifiable concentrate or microemulsion.

Embodiment 3

[0035] Embodiment 3: drying waxberry branches and leaves to a water content of 7%, pulverizing into 45 order powder, weighing 150kg pulverized matter; using ethyl acetate 450kg, extracting under 70 ℃ of temperature conditions, all the other are identical with embodiment 1 method, Concentrate at last to obtain 150kg of extract for subsequent use. Contrast the corresponding raw materials of Example 3 in Table 1 and the parts by weight thereof respectively with the same method as Example 1 (high-speed stirring temperature 55° C.) to prepare bactericide emulsifiable concentrate or microemulsion.

[0036] With the above three embodiments, the remaining five embodiments can be deduced according to the proportions in Table 1, and will not be listed one by one.

[0037] When preparing the extract, in addition to selecting the extraction solvent from factors such as cost and the performance of dissolving active ingredients, among the 8 examples listed in Table 1, examples 6, 7, and 8 a...

Abstract

The present invention relates to a strawberry tree twig and leaf extract germicide and its production method. Said production method includes the following procedures: drying and pulverizing, reflux dissolving, centrifugal separation and vacuum concentration to obtain extract, then using (by weight portion) 30-80 weight portions of above-mentioned extract, 20-50 portions of solvent and 10-20 portions of adjuvant to prepare 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 them into germicide microemulsion. Said germicide can be mainly used for controlling 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 bayberry branches and leaves as raw materials and a production method thereof. Background technique [0002] Myrica rubra Sieb.et Zucc, Myrica rubra Sieb.et Zucc, is Myricaceae, Myrica rubra is a fruit tree, mainly produced in Jiangsu, Zhejiang, Jiangxi, Guangdong and other provinces. "Compendium of Materia Medica" records that the roots, stems, and fruits of bayberry can be used as medicine, which have the effects of stopping bleeding, relieving pain, treating scalds, treating carbuncles, and stopping diarrhea. Waxberry leaves can also treat diseases such as burns, carbuncles, and abdominal pain. Red bayberry leaves contain a variety of phenolic compounds, mainly flavonoids and proanthocyanidins. There have been reports on the use of bayberry branch and leaf extract as an antioxidant for food preservation, but there are no data reports ...
