Background
Pineapple wilt is a disease caused by pineapple wilt virus (PMWaV), which is the most important viral disease of pineapples and often causes the growth stop and root group necrosis of pineapple plants, leaves fade to green and turn to red, leaf tips lose water and shrink and roll back downwards, and finally the tops of diseased plants and even the entire plants wither.
The oxine-copper is a quinoline protective low-toxicity bactericide, belongs to organic copper chelates, and has good prevention and treatment effects on fungal and bacterial diseases. After spraying, a tight protective medicine film can be formed on the surface of the plant, the affinity with the plant is strong, and the rain wash resistance is realized; the medicinal film slowly releases bactericidal copper ions, and effectively inhibits invasion and germination of germs, thereby achieving the purpose of preventing and treating diseases. The prior literature also reports that oxine-copper has the effect of preventing and treating virus diseases.
The novel antiviral agricultural antibiotic and bactericide of cytosin of the pyrimidinomycin genus is produced by streptomyces hygroscopicus, and can inhibit the proliferation of viruses in plants, inhibit the absorption capacity of the viruses to protein and inhibit the synthesis of virus nucleic acid; meanwhile, the plant can be induced to generate disease resistance, PR protein and the activity of defense enzyme system in the plant body can be improved. The pyriminocycline has higher control effect on diseases caused by fungi, bacteria and viruses on various crops, and is green and environment-friendly.
The pesticide is easy to generate resistance risk and increase the risk by using the pesticide for a long time, and further the prevention and control cost and the environmental stress are increased. The composition with the synergistic effect is screened out by compounding the pesticides, so that the use amount of the pesticides can be reduced, the prevention and treatment cost is reduced, the resistance risk is reduced, and the potential environmental risk can be reduced.
At present, no related report of compounding bacillus subtilis and oxine-copper or pyriminomycin exists.

the first purpose of the invention is to provide a biological pesticide for resisting pineapple wilt, and the active ingredients of the biological pesticide consist of bacillus subtilis and oxine-copper or pyriminomycin, wherein the bacillus subtilis is 1000 hundred million CFU/g of the bacillus subtilis.
Preferably, the bacillus subtilis and the oxine-copper are 1-9:9-1.
Preferably, the bacillus subtilis and the pyriminomycin have a ratio of 1-30:25-1.
Preferably, the bacillus subtilis and the pyriminomycin 1:7.5.
the second purpose of the invention is to provide a pesticide preparation which comprises the biological pesticide for resisting the pineapple wilt.
The invention also provides application of the biological pesticide for resisting the pineapple wilt disease or the pesticide preparation in preventing and treating plant virus diseases.
Compared with the prior art, the invention has the following beneficial effects:
(1) When the bacillus subtilis and the oxine-copper or the pyriminomycin in the active ingredients of the biological pesticide are compounded, the synergistic effect is shown in a certain mass ratio range, the prevention and treatment effect on the pineapple wilt can be improved, the use dosage of the pesticide is favorably reduced, and the prevention and treatment cost and the environmental pollution are reduced.
(2) The bacillus subtilis, the oxine-copper and the pyriminomycin in the active ingredients of the biopesticide have different action mechanisms on viruses, can delay the generation and development of drug resistance of the pineapple wilt virus, and can delay the service life of the pesticide to a certain extent.
Detailed Description
The present invention will be better understood from the following examples, which are given for illustrative purposes only and should not be construed as limiting the invention as detailed in the claims.
Examples: laboratory biological activity test
1. Testing a toxic source: fresh pineapple leaves infected with pineapple wilting disease virus (PMWaV) are cut in a Tainong No. 16 pineapple planting field, 0.01mol/L PBS buffer solution with pH7.2 is added, a little quartz sand with 500 meshes is added, ground homogenate is obtained, and residues are filtered by 4 layers of gauze to obtain virus liquid for later use.
Wherein the ratio of the mass of the fresh leaves to the volume of the PBS buffer is 50mg:1L of the compound.
2. Reagent for testing
1000 hundred million CFU/gram Bacillus subtilis parent drug (Nemontage Yongtai chemical Co., ltd.);
98.5% oxine-copper (Shaanxi Meibang pharmaceutical industry group, inc.);
30% of the pyriminomycin parent drug (Dajinghuayazaikai Co., ltd.).
Preparing bacillus subtilis mother liquor into a bacterial solution by using sterile water of 0.1 percent of tween-80; dissolving oxine-copper with dimethyl sulfoxide to prepare single-dose mother liquor, and diluting with 0.1% Tween-80 aqueous solution; the pyriminocycline is dissolved and diluted by clear water. Sets multiple groups of mixture ratios, and sets 5 gradient mass concentrations for each single agent and each group of mixture ratio according to an equal ratio method, and the agents are used as the medicines at present.
3. Test method
Selecting strong and healthy Tainong No. 16 pineapple seedlings with 6 leaves, spraying carborundum on the surface of each leaf, dipping virus liquid with a brush, slightly rubbing and carrying out friction inoculation. After inoculation, the surface of the leaves is lightly washed by clear water, and after the leaves are dried, the liquid medicine is sprayed once every 5 days and is sprayed for 3 times totally. During the culture, the culture medium is placed in a light incubator at the temperature of 25 +/-1 ℃. Each liquid treatment set was 3 replicates, each replicate 20 seedlings. Spraying clear water to treat the blank as a blank control. Inoculation 14d investigates the onset of disease and calculates disease index and relative control.
4. Disease level counter
TABLE 1 disease progression table
