Description
Technical Field
The invention relates to disease control of mulberry, in particular to disease control of mulberry caused by bacteria, belonging to the technical field of pesticide production.
Background
Mulberry belongs to Moraceae, is deciduous arbor, and is feed for Bombyx mori, and folium Mori is egg-shaped. China is the earliest country for breeding mulberry silkworms in the world, the breeding mulberry silkworms are one of great contributions of Chinese nationalities to human civilization, the mulberry picking and silkworm breeding are common agricultural lives as early as the world, and the mulberry is planted in pieces in the spring, autumn and war country.
In the process of cultivation and growth of the mulberry, diseases and insect pests are easy to happen. The main diseases are: blight caused by virus, powdery mildew, brown spot (leaf rot) and red rust (yellow dog disease) caused by fungi, mulberry blight caused by bacteria, bacterial blight caused by weak parasitic bacteria, and mulberry root nematode disease, etc. The mulberry blight disease is also called bacterial disease, blight, bacterial wilt or head rot, generally occurs in high-temperature and high-humidity environments in 7 and 8 months, is fierce in coming and fast in onset, and belongs to destructive diseases of mulberry.
The mulberry blight is caused by bacterial parasitism of pseudomonas, pathogenic bacteria mainly damage tender leaves and terminal buds, oil stain-shaped tawny disease spots appear after the tender leaves are attacked, the disease spots are changed from small to large to form scattered polygonal disease spots, leaves are shrunk, turned yellow and shed, disease spots on veins and petioles are longitudinally split into black strip disease spots, and the terminal buds are usually blackened and died after being attacked.
In the prior art, the method for preventing and treating the mulberry epidemic disease mainly comprises the following steps: (1) spraying lime sulfur in spring for sterilization; (2) applying organic fertilizer, especially applying phosphorus-potassium fertilizer, and using soil chain antibiotic for preventing and treating; (3) cutting off diseased leaves of diseased branches, burning, and spraying 0.6-0.7% Bordeaux mixture; (4) when the disease condition is serious, the mulberry is dug out, and the soil is disinfected by formalin solution. It can be found that people have no good method for preventing and treating the mulberry epidemic disease, and the prior art has obvious defects: the increased application of organic fertilizer belongs to a measure of 'strengthening body', and at most, only 'prevention' but not 'treatment' can be realized; the soil chain antibiotic, the Bordeaux mixture or the formalin solution is adopted to kill bacteria in soil only, and has no effect on bacteria in air flow and water flow, and the bactericides are artificially synthesized chemical preparations and have certain negative effects on the ecological environment in the nature.
Due to the fact that bacterial blight of the mulberry is the main disease in mulberry planting in China, the occurrence of the bacterial blight becomes more serious particularly in middle and lower reaches of Yangtze river, and mulberry farmers reduce the yield of mulberry leaves by about 5-6 times due to the mulberry blight, so that loss is huge.
Disclosure of Invention
The invention aims to make up the defects of the prior art in the measure for preventing and treating the mulberry epidemic disease, thereby providing a medicament which has wide raw material source, convenient preparation and good effect of preventing and treating the mulberry epidemic disease, and providing a use method of the medicament.

Detailed Description
The invention provides a compound pesticide for preventing and treating rice blast and a use method thereof, and is characterized in that: the preparation contains ethylicin and amino-oligosaccharin; the ethylicin is garlic extract, and the amino-oligosaccharin is shell extract.
Preferably, the compound pesticide for preventing and treating rice blast is characterized in that: the medicament comprises (by weight percent) —
More preferably, the compound pesticide for preventing and treating rice blast is characterized in that: the medicament comprises (by weight percent) —
In the compound pesticide for preventing and treating rice blast, the used auxiliary agent is a mixture of phosphate and high molecular polyether.
In the medicament provided by the invention, the ethylicin is a garlic extract. The garlic is a common plant in the nature, and generally has no disease in the growing process because the ethylicin contained in the garlic has strong antibacterial and bactericidal effects. Moreover, the properties of garlic are not affected by the planting area, which shows that ethylicin can effectively resist various bacteria in the nature. The mulberry is also planted in the nature and faces an environment similar to that of garlic, so that the agent is added after the ethylicin is extracted, and a good sterilization effect can be achieved. On the other hand, in the medicament provided by the invention, the amino-oligosaccharin is a shell extract, and through years of research and experiments, the inventor finds that the amino-oligosaccharin has a good effect of promoting recovery of a diseased plant after the disease of the mulberry, so that the amino-oligosaccharin is applied while ethylicin is used for sterilization, the effect of promoting recovery of the diseased plant to continue normal growth can be realized while killing bacteria and avoiding the range expansion of the disease of the mulberry, and the influence of the disease on the mulberry is reduced to the minimum, and the best prevention and treatment effect is achieved. Therefore, the inventor proposes the patent application of the invention, and aims to disclose the technical scheme, thereby benefiting the vast mulberry field; while disclosed, protection against patent grants are also desired.
The inventor researches and discovers that when the weight percentage of ethylicin and amino-oligosaccharin in the medicament is 50-75% and 0.5-5%, the control effect on the mulberry blight is good; particularly, when the content of ethylicin is 60 +/-1.5 percent and the content of amino-oligosaccharin is 2 +/-0.3 percent, the prevention and treatment effect is best. In addition, when the medicament is prepared, the auxiliary agent is preferably a mixture of phosphate and high-molecular polyether, and the content of the auxiliary agent is generally 10-30%.
When the medicament is prepared, the auxiliary agent and ethylicin are mixed, then water is added, and finally the amino-oligosaccharin raw powder is added. Specifically, firstly putting raw ethylicin and an auxiliary agent into a kettle in proportion, mixing and stirring for 30 minutes, and strictly preventing any hard metal from falling into a container during stirring so as to avoid damaging the wall of the kettle; and then adding water and the amino-oligosaccharide raw medicine in a set proportion into the kettle, continuously stirring for 30 minutes to fully mix the raw medicine, finally pumping the materials into a head tank, and precipitating for 120 minutes.
The compound pesticide for preventing and treating rice blast is microemulsion, the pH value is 2.0-6.0, the lasting foamability (after 1 min) is less than or equal to 60mL, and the emulsion stability is still qualified after 200 times of dilution. A plurality of field experiments of the inventor show that the medicament can effectively prevent and treat the mulberry epidemic disease, and the disease condition of the mulberry epidemic disease can be controlled and treated by root irrigation or a method of root irrigation and spraying in a severe disease field; in the case of a slightly ill field, the spraying can be performed by a continuous spraying method. Therefore, the pesticide can act on bacteria in soil, water flow and air flow, and the results of continuous three-year field pesticide effect tests show that the pesticide and the using method thereof have the disease prevention effect of more than 90 percent and the recovery rate of diseased plants of more than 90 percent.
