Abstract

The invention discloses a preparation method of a botanical fungiticide composition containing pepper shell extract. The method comprises the following steps: firstly, using pepper shells as a raw material, adopting an extracting solution for treatment, and preparing a pepper shell extracting solution; then using a sapindus mukorossi peel as a raw material, adopting an extracting solution for treatment, and preparing a sapindus mukorossi peel extracting solution; finally mixing the obtained pepper shell extracting solution and sapindus mukorossi peel extracting solution, then adding sodium lignin sulfonate, adding porous nanometer titanium oxide after the solution is uniformly stirred, and performing ultrasonic treatment at 500W power, so as to prepare the botanical fungiticide composition. The botanical fungiticide composition is good in stability and excellent in bactericidal performance, the preparation method is simple, and the cost is low.

Description

Technical field: [0001] The invention relates to the field of agriculture, in particular to a preparation method of a botanical fungicide composition containing pepper shell extract. Background technique: [0002] At present, low-toxic chemical pesticides are mainly used for the prevention and control of fungal diseases of crops such as vegetables, fruit trees, tea, garden flowers, pastures, etc., such as powdery mildew, gray mold, anthracnose, etc. These pesticides contain copper, sulfur and other harmful substances of different components. As a result of long-term use of low-toxic chemical pesticides, toxic substances in plants are left, which not only pollutes the ecological environment, but also brings different degrees of harm to human health. [0003] Zanthoxylum bungeanum belongs to the plant of Rutaceae. It has a pungent taste and a strong aroma. It is one of the unique edible spices in my country. There are about 250 species in the world, distributed in tropical a...
