Embodiment 1

[0022] Matrine 1.0%, sanguinarine 1.2%, walnut peel flavone 0.8%, amino oligosaccharin 1.5%, organic silicon 0.1%, polyoxyethylene ether 0.1%, copper sulfate 1.0% and nano-biomass charcoal powder 0.6% Mix according to the above ratio, then add water with a measuring cylinder, the water temperature is 25°C, stir while adding, mix well, and set the volume to 100ml.

[0023] Wherein, the matrine is selected from Sophora flavescens as a raw material, and is extracted by 95% ethanol extraction at 65-70°C. The sanguinarine is obtained from Boluohui raw material by 95% ethanol extraction. The walnut peel flavonoids are made of green walnut peel as a raw material, which is carried out by adopting the method of ethanol concentration of 65% and water bath temperature of 65°C. The nano-biomass charcoal powder is made of peanut shells, sawdust or bamboo as raw materials, carbonized at 400-450°C, and then processed by cascade crushing, firstly crushed to 20 mesh, and then loaded into a ba...

Abstract

A plant-derived compound preparation for preventing and treating Liaodong flue-cured tobacco target spot disease and its preparation and spraying method, which is mainly derived from plant extracts. The main components of the plant-derived compound preparation include: matrine, sanguinarine, walnut peel flavonoids, and amino-oligosaccharides element, silicone, polyoxyethylene ether, copper sulfate and nano-biomass charcoal powder. During the production process of the plant-derived compound preparation, the above-mentioned substances are added in proportion to water at a temperature of 25°C-30°C, stirred while adding, and fully mixed evenly. The plant source compound preparation of the present invention is the preferred biological preparation for the production of organic green agricultural products. It is non-toxic and harmless and can be degraded naturally. It can be extended to agricultural crops such as tobacco, fruit trees, and vegetables, which has important practical significance for the development of ecological agriculture and green agriculture.

Description

technical field [0001] The invention belongs to the technical field of crop green biological prevention and control, and in particular relates to a plant source compound preparation for preventing and treating Liaodong flue-cured tobacco target spot disease and a preparation and spraying method. Background technique [0002] Tobacco target spot (Rhizoctonia solani Kuhn) is a new tobacco disease that has emerged in my country in recent years. It is a fungal disease caused by Rhizoctonia solani AG-3 (Rhizoctonia solani). It was found on the plant, and its pathogenic bacterium was identified, and it was determined that it was the genus Pleurotus mellifera. [0003] In recent years, the disease has been prevalent in a large area in Northeast my country. It is a new domestic tobacco disease with a short incubation period and rapid prevalence. It has caused huge losses to the quality and yield of tobacco leaves. Tobacco target spot disease can occur from tobacco seedlings to matur...
