Embodiment 1

[0022] Combine 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 in a graduated cylinder, the water temperature is 25℃, stir while adding, mix well, and dilute to 100ml.

[0023] Wherein, the matrine is extracted with Sophora flavescens as a raw material, using a 95% ethanol extraction method, at 65-70°C. The sanguinarine is obtained by selecting the raw material from Boduo and using a 95% ethanol extraction method. The walnut peel flavonoids are made of green walnut peel as a raw material, with an ethanol concentration of 65% and a water bath temperature of 65°C. The nano-biomass charcoal powder is made of peanut shells, wood chips or bamboo as raw materials, and is carbonized at 400-450°C, and then processed by cascade crushing. Firstly, it is crushed to 20 mesh, and then loaded into a b...

Abstract

The invention discloses a plant source composite preparation for preventing Liaodong flue-cured tobacco target leaf spots and a preparation and spraying method. The plant source composite preparationis mainly from plant extracts and mainly comprises sophocarpidine, sanguinarine, walnut skin flavonoid, amino-oligosaccharin, organic silicon, polyethenoxy ether, copper sulfate and nano-biomass carbon powder. In the production process of the plant source composite preparation, the materials are added into water with the temperature of 25-30 DEG C in proportion, and the materials are stirred whenbeing added and sufficiently and uniformly mixed. The plant source composite preparation is preferably biological preparation for producing organic green agricultural products and free from toxicity and harm and can be nationally degraded, outbreak of the target leaf spots in growth process of flue-cured tobaccos can be restrained, the incidence rate of other fungi or bacterial diseases is reduced, the plant source composite preparation can be widely used for agricultural crops such as tobaccos, fruit trees and vegetables and has important practical significance for 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-derived compound preparation for preventing and curing target spot disease of flue-cured tobacco in Liaodong, and a preparation and spraying method. Background technique [0002] Tobacco target spot disease (Rhizoctonia solani Kuhn) is a new tobacco disease that has appeared 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 the pathogenic bacteria was further identified, and it was determined that it belongs to the genus Basidiola. [0003] In recent years, the disease has been widespread in northeastern my country. It is a new domestic tobacco disease with a short incubation period and a rapid epidemic, which has caused huge losses to tobacco leaf quality and yield. Tobacco target spot disease can occur from tobacco seedling to maturity, an...
