Problems solved by technology

Due to the large volume of the finished extract, it is difficult to store and transport
If the water in the extract is to be evaporated to separate the extract, it is an energy-intensive preparation process, which will inevitably greatly increase the manufacturing cost

Embodiment Construction

[0039] Camellia oleifera extract of the present invention is prepared by extracting and purifying tea saponin ( figure 1 ) to make it have high bioactive ingredients, the active ingredients mainly include triterpenoid saponins and flavonoids, which can be used to control soft snails such as flat snails, African giant snails and apple snails Animals and root-knot nematodes, and can also inhibit the growth of Penicillium, green mold, Rhizoctonia solani, Fusarium oxysporum, anthracnose and other microorganisms.

[0040] refer to figure 1 The preparation process of the extraction and purification of tea saponin roughly includes five stages of pretreatment 1, oil removal 2, tea saponin extraction 3, tea saponin purification 4 and post-treatment 5, as follows:

[0041] First, in the stage of pretreatment 1, the camellia oleifera sample (tea oleifera cake) is pulverized with a grinder (step 11), and sieved with a sieve of ≧60 mesh to increase its contact surface area with the solven...

Abstract

This invention relates to a camellia seed extract and biopesticides with the extract. The camellia seed extract contains by weight of 0.5-99% triterpenoid saponins, 0.5-40% flavonoids, and 0-20% phenolic compounds. The biopesticides may serve as molluscicides, for example, for prevention and control of pests or pathogens.

Description

technical field [0001] The present invention relates to a plant extract and the biopesticide prepared therefrom, especially an extract extracted from camellia oleifera and the biopesticide prepared therefrom, which are used to prevent and control molluscs, nematodes or inhibit Plant disease microbial growth, etc. Background technique [0002] In recent years, the awareness of environmental protection has risen. Since natural saponin (saponin) can be quickly decomposed by microorganisms and will not impact the environment, the use of saponin from plant extraction has received renewed attention. For example, the recycling of camellia oleifera meal (also known as bitter tea meal). Camellia oleifera meal is derived from the oil residue of the tea seeds of the bitter tea tree. Because it is rich in tea saponin, it can not only be used as a natural cleaning agent, but also destroy the mucous membrane of the apple snail, resulting in the death of the apple snail. Therefore, it is ...
