Manufacturing method for anti-pseudomonas solanacearum medicine

Abstract

The invention discloses a manufacturing method for an anti-pseudomonas solanacearum medicine. The manufacturing method comprises the following steps: A, preparing materials which comprise 50% of chlorothalonil wettable powder, 12% of green emulsified copper missible oil, streptomycin sulphate wettable powder, cinnamyl aldehyde, sophocarpidine, polyoxin, radix bupleuri and coriander; B, leaching the extraction solution of radix bupleuri and coriander by virtue of alcohol, namely breaking, cleaning and airing radix bupleuri and coriander, then putting the broken, cleaned and aired radix bupleuri and coriander in an airtight container, adding 70wt% ethanol solution, soaking and airtightly brewing the radix bupleuri and coriander for 12 hours, then putting the radix bupleuri and coriander in a percolater which is of a bucket structure, wherein the bottom of the percolater is a cone, and equipment provided with a switch capable of dripping water is connected below the cone and used for extracting the ingredients of the medicinal materials: uniformly putting the medicinal materials in the bucket, adding a soaking solution which is water or wine, and slowly dripping, collecting a percolation solution, and heating to recover ethanol, thereby obtaining an extraction solution; C, compounding 50% of chlorothalonil wettable powder, 12% of green emulsified copper missible oil, streptomycin sulphate wettable powder, cinnamyl aldehyde, sophocarpidine and polyoxin with the extraction solution obtained in the step B, uniformly stirring, and sterilizing with ultraviolet rays, so as to obtain the anti-pseudomonas solanacearum medicine. The manufacturing method disclosed by the invention is simple; the prepared product is simple in manufacturing method, simple in proportioning, convenient to use, and good in the effect of treating the pseudomonas solanacearum of potatoes.

Description

[0001] Technical field: [0002] The invention relates to vegetable medicines, in particular to a preparation method of medicines against R. solanacearum. [0003] Background technique: [0004] Bacterial wilt is the main disease of potato. The main symptom is that the plants wilt and die quickly, and the stems and leaves remain green. The browning part of the diseased stem is squeezed by hand, and milky white bacteria liquid is discharged. The disease is prone to occur under the conditions of high temperature and high humidity, continuous cropping, low-lying soil, water accumulation in the field, acidic soil, and partial application of nitrogen fertilizers. Ralstonia solanacearum can enter the soil together with diseased plant residues. Long-term survival forms a source of infection. Soil moisture has a great influence on its survival in the soil. In alluvial soil with high humidity, it can survive for up to 2 to 3 years, but in dry soil, it can only survive for a few...
