Biological preparation for preventing and treating candidatus liberibacter of red honey pomelos

Abstract

The invention belongs to the technical field of agriculture and in particular discloses a biological preparation for preventing and treating candidatus liberibacter of red honey pomelos. The biological preparation is prepared from the following raw materials in parts by weight: 20-30 parts of a traditional Chinese medicine extract, 0.1-0.2 part of a complex microbial bacterium, 0.5-1 part of fructose, 0.5-1 part of a film formation agent, 0.1-0.2 part of a stabilizer, 0.2-0.3 part of monopotassium phosphate, 0.2-0.3 part of ferrous sulfate, 0.02-0.04 part of epsilon-polylysine and 0.01-0.02 part of citric acid, wherein the traditional Chinese medicine extract is prepared from the following components in parts by weight: 6-8 parts of onions, 3-5 parts of chamomile, 10-15 parts of Chinese violet, 10-15 parts of salix leaves, 8-10 parts of herba schizonepetae, 3-5 parts of radix ophiopogonis, 3-5 parts of scutellaria baicalensis, 4-6 parts of ailanthus altissima, 8-10 parts of eucalyptusleaves, 3-5 parts of radix sophorae flavescentis and 4-6 parts of fennel. The biological preparation disclosed by the invention has a very good killing function on vector insects, namely woodlice which propagate candidatus liberibacter, and candidatus liberibacter pathogenic bacteria, namely gram negative bacteria, in addition, is good in stability, that is, a good medicinal effect can be maintained for a long time in a natural environment, and is remarkable in effect in preventing and treating candidatus liberibacter of red honey pomelos.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to a biological agent for preventing and treating huanglongbing disease of pomelo with red heart Background technique [0002] Red heart pomelo, also known as red meat pomelo, red heart pomelo, red meat pomelo, blood pomelo, has the advantages of large fruit, thin peel, more juice and high sweetness. Red heart pomelo is rich in carotene and other vitamins, and the content of calcium and iron is relatively high. The pectin of red heart honey pomelo can reduce the damage of the human artery wall. Long-term consumption can prevent diseases such as liver disease, arteriosclerosis and diabetes. Due to the unique flavor and high nutritional value of red heart pomelo, the market demand for red heart pomelo is increasing day by day, so the planting industry of red heart pomelo has broad market prospects and economic benefits in China. The red heart honey pomelo planting technology ha...
