Abstract
The invention, which belongs to the technical field of pharmaceutical product research and development, relates to a compound Rhus chinensis Mill preparation and its purpose. A method for producing the compound Rhus chinensis Mill preparation comprises the following steps of: respectively taking Rhus chinensis Mill leaves, dandelions and masson pine needles, respectively adding ethanol, extracting by concussion on a shaker, and centrifuging by a centrifuge to obtain supernatants; repeating to extract twice, merging the three supernatants, filtering, treating the filtrate by decompression concentration, followed by drying to obtain extract products of the Rhus chinensis Mill leaves, dandelions and masson pine needles; taking triturated garlics, adding the triturated garlic into a round-bottom flask, followed by steam distillation to obtain garlic essential oil; and taking the extract products of the Rhus chinensis Mill leaves, dandelions and masson pine needles as well as the garlic essential oil to produce the compound Rhus chinensis Mill preparation. The product provided by the invention has a bacteriostasis effect on Fusarium oxysporum f.sp.vasinfectum, fusarium moniliforme and Botrytis cinerea, can be used to develop corresponding preparations for controlling plant diseases, and is suitable for industrial production.
Description
technical field [0001] The invention belongs to the technical field of research and development of pharmaceutical products. The invention relates to a compound salt skin wood preparation and its application. The product of the invention has antibacterial effect on cotton fusarium wilt, Fusarium moniliforme and Botrytis cinerea, and corresponding preparations can be developed for preventing and controlling plant diseases, and the product of the invention is suitable for industrial production. Background technique [0002] The reduction of crop yield and harvest caused by plant pathogenic fungus diseases is the main obstacle to agricultural development. For many years, people have mainly used chemical control to prevent and control this problem. Longer, it has a destructive effect on the natural ecology, forms a public nuisance, and some even endangers human health. Therefore, it has become a top priority to develop botanical pesticides that are highly effective against harm...
