Technical Field
The invention relates to the technical field of plant disease prevention, in particular to a bacteriostatic liquid for preventing and treating fungal diseases of plants, a preparation method and a use method thereof.
Background
Among plant diseases, 70-80% of the diseases are caused by pathogenic fungi infection. The plant fungal diseases refer to diseases that plant roots, stems or leaves are infected by fungal pathogenic bacteria living in soil or air under proper conditions, so that plants are wilted and died, even fruits are damaged, so that the fruits are diseased or rotted, and the yield is influenced. The plant fungal diseases not only directly cause the reduction of the yield and the quality of crops, but also cause a plurality of toxins and metabolites harmful to human and livestock to be secreted and generated by part of pathogenic fungi in the process of infecting the crops, thereby forming a great threat to the safety of agricultural products. The fungal pathogens are spread in various ways, infect and cause systemic diseases of plants, and cause great loss to agricultural production, and common fungal diseases of crops mainly comprise anthracnose, rust diseases, powdery mildew, downy mildew, leaf blight, soot disease and the like. At present, the types and the quantity of medicaments for preventing and treating the fungal diseases in China are few and few, and the medicaments are mostly copper preparations and antibiotic medicaments, and the new varieties are few. After long-term use, pesticide residue, environmental pollution and drug resistance of germs are increasingly serious, and the prevention and treatment effect of the existing medicament is increasingly reduced.
At present, the control of plant fungal diseases is mostly chemical control and microbial control. Chinese patent document CN102972398A discloses an application of a compound in controlling plant fungal diseases caused by alternaria alternata, in particular to an application of 2-methyl-5-isopropyl phenol in controlling plant fungal diseases caused by alternaria alternata, and the invention content is as follows: the OP-10 emulsifier is added into the 2-methyl-5-isopropyl phenol according to the proportion of 1-45% of the total volume and dissolved by acetone to prepare a 1-80% (w/w) 2-methyl-5-isopropyl phenol solution which is used for preventing and treating tomato early blight, cabbage black spot and tobacco brown spot caused by alternaria alternate. However, the chemical bactericide not only pollutes the environment in production and has high production cost, but also inevitably causes environmental pollution and agricultural product pesticide residue problems by repeated application.
Therefore, the development of novel, highly effective, low-toxicity, environment-friendly fungal disease control agents is very necessary and urgent.

Example 4
Test subjects: diseased apple trees with brown spot (brown spot of apple is caused by fungal disease, mainly harming apple leaves).
The test method comprises the following steps: the bacteriostat for controlling plant fungal diseases obtained in the example 3 is diluted according to the proportion of 1: 100, 1: 150, 1: 200, 1: 250 and 1: 300 respectively, and a clear water group is used as a blank control group. The diseased apple trees with brown spot are observed and detected by spraying 3 diseased apple trees in each treatment, the percentage of the leaves with diseased spots of each apple tree before spraying, 10 days after spraying for the first time and 10 days after spraying for the second time is respectively counted, the average value is taken, and the result is shown in table 1.
The spraying method comprises the following steps: spraying 150ml of diluted antibacterial solution to each fruit tree, and continuously spraying for 2 times at intervals of 10 days.
TABLE 1 statistical results
As is apparent from the description in Table 1, the bacteriostatic agent for controlling fungal plant diseases obtained in example 3 was diluted at a ratio of 1: 200, and had an excellent effect of controlling cercospora leaf spot of apple. The 1: 150 and 1: 250 treatment groups had slightly poor control of apple brown spot. As can be seen from the treatment groups of 1: 100 and 1: 300, the dilution ratio of the bacteriostatic solution for preventing and treating the fungal diseases of plants cannot be too large or too small, otherwise, the technical effect of effectively preventing and treating the cercospora leaf spot of the apple cannot be achieved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
