Embodiment 1

[0019] Example 1 5% Polygonum cuspidatum extract wettable powder

[0020]

[0021] Processing method: According to the formula requirements, measure various additives and carriers (except the active ingredient Polygonum cuspidatum extract) into the mixer, start stirring, mix evenly, put it into the intermediate silo, and grind it through ultra-fine grinding machine for crushing. The pulverized material is put into a gravity-free mixer, and the extract of Polygonum cuspidatum is sprayed from the top. After mixing evenly, a 5% wettable powder product of Polygonum cuspidatum extract is obtained. After testing, the physical indicators of the product are: fineness (through a 44μm standard sieve) of 98%; water content of 2.2%; wetting time of 95 seconds; suspension rate of 88%; pH value of 6.2; thermal storage stability is qualified.

Embodiment 2

[0022] Example 2 30% Polygonum cuspidatum extract wettable powder

[0023]

[0024] Processing method is the same as embodiment 1. After testing, the physical indicators of the product are: fineness (through a 44μm standard sieve) of 97%; water content of 2.4%; wetting time of 87 seconds; suspension rate of 85%; pH value of 6.3; thermal storage stability is qualified.

Embodiment 3

[0025] Example 3 20% Polygonum cuspidatum extract water-dispersible granules

[0026]

[0027]

[0028] Processing method: According to the formula requirements, measure various additives and carriers (except the active component Polygonum cuspidatum extract) and add them into the mixer, start stirring, mix evenly, put them into the intermediate silo, and grind them through superfine grinding machine for crushing. Put the pulverized material into the mixer and mix it. After mixing evenly, granulate it through a granulator, add the prepared granules into the gravity-free mixer, spray the Polygonum cuspidatum extract according to the amount, and mix well to obtain water The crude dispersible granules are dried to obtain 20% Polygonum cuspidatum extract water dispersible granules. After testing, the physical indicators of the product are: wet sieve test (through 75μm standard sieve) is 98%; moisture is 1.9%; wetting time is 30 seconds; suspension rate is 90%; pH value is 6...

Abstract

The invention belongs to the field of pesticide bactericides, and provides a l pesticide pesticide Rhizoma Polygoni Cuspidati extract solid preparation. The solid preparation can be a wettable pulvis, a water dispersible granule, an effervescent tablet and the like. The invention also provides a preparation method of the solid preparation. The preparation method has the advantages of simplicity, fixing apparatus use, stable and reliable operation, easy batch production, and solving of a problem that qualified products are difficult to obtain through routine processing methods. The Rhizoma Polygoni Cuspidati extract solid preparation is suitable for controlling diseases on a plurality of crops comprising rice, vegetables, fruits and the like. No organic solvents are used in the invention, so the phytotoxicity to the crops is mitigated, and it is in favor of the drug effect performance of a Rhizoma Polygoni Cuspidati extract.

Description

technical field [0001] The invention belongs to the field of pesticide processing, and relates to a solid preparation of botanical pesticides and a preparation method of the preparation, in particular to a solid preparation of Polygonum cuspidatum extract and its preparation method and application. Background technique [0002] Botanical pesticides are currently an important guarantee for the safety and export of agricultural products. At the same time, they have important economic, social and environmental benefits for the development of green agriculture and the promotion of sustainable development of agricultural production. Chinese invention patent CN1961667A reports an agricultural fungicide with emodin methyl ether and chrysophanol extracted from Polygonaceae plants as active components, which has obvious preventive and therapeutic effects on various plant diseases. Polygonum cuspidatum This product is the stem and root of Polygonum cuspidatum Sieb.et Zucc, which is an...
