Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a bactericidal composition for preventing and treating tomato diseases and application thereof.
Background
In order to improve the tomato yield, basic technical management needs to be strengthened in the process of carrying out tomato cultivation, the temperature requirement of tomato cultivation is relatively high, and the temperature is required to be kept between 20 ℃ and 25 ℃. In order to ensure that the growth environment of the tomatoes is good, the factors of planting soil, temperature, humidity and the like are strictly controlled, the disease control work is emphasized and done, the pollution-free planting standard needs to be adhered to, and the planting yield and quality of the tomatoes are improved.
Tomato gray mold is a worldwide disease with serious harm caused by botrytis cinerea. For a long time, the method for preventing and controlling the botrytis cinerea mainly applies a large amount of chemical pesticides, but the characteristics of fast propagation, large variation degree and the like of the botrytis cinerea lead the botrytis cinerea to easily generate drug resistance to chemical agents, on the other hand, the understanding of people on the drug resistance and the food safety problem is continuously improved, and the demand of preventing and controlling the botrytis cinerea by using a biological prevention and control technology is more urgent.
The chemical bactericide plays an important role in preventing and treating plant diseases, but after long-term use, the pesticide resistance is enhanced, the prevention effect is reduced, the using amount is increased, and meanwhile, the ecological environment is polluted. How to reduce the side effect of chemical pesticides is a problem to be solved urgently at present. Biological control is the most potential safe control technology which can well replace chemical pesticides.
The polyoxin belongs to plant-derived broad-spectrum antibiotics, has a good systemic conduction effect, has an action mechanism of interfering the biosynthesis of bacteria cell wall chitin, and has the effects of locally expanding, cracking and overflowing cell contents after a germ tube and mycelium contact a medicament, causing death due to abnormal development and inhibiting the sporulation of pathogenic bacteria and the enlargement of disease spots. The main control objects are various fungal diseases such as wheat powdery mildew, tobacco brown spot, cucumber downy mildew, melon wilt, ginseng black spot, rice sheath blight, apple alternaria leaf spot, strawberry and grape gray mold, forest blight, pear black spot and the like.
Perillaldehyde is a natural mono-mushroom compound, is colorless to pale yellow liquid, and is abundantly present in perilla. Currently, only a few studies on the antibacterial activity of the compound have described the antibacterial effect, and the antifungal effect is only sporadically reported to the genus Saccharomyces.
In the prior art, no report related to the application of perillaldehyde to tomato gray mold is provided, and no report related to the combined application of polyoxin and perillaldehyde is disclosed.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the following technical scheme:
a bactericidal composition for preventing and treating tomato diseases comprises active ingredients of polyoxin and perillaldehyde, wherein the mass ratio of polyoxin to perillaldehyde is 20:1-1: 20. In particular to the mass ratio of the polyoxin to the perillaldehyde is 10:1-1: 1.
The preparation of the bactericidal composition is wettable powder, water dispersible granules and suspending agent; the mass percentage of the active ingredients in the preparation is 1-50%. In particular, the preparation can be wettable powder
The bactericidal composition is used for preventing and treating diseases of tomato crops, and particularly the diseases are tomato gray mold.
By adopting the technical scheme, the invention has the following beneficial effects:
when the number is more: the mass ratio of the purple is 10:1-1: the composition shows obvious synergistic effect on tomato gray mold at 1 time, and particularly, the composition has the following advantages: when the mass ratio of the purple is 5:1, the CTC value is 148.95, and the purple has a synergistic effect. The polyoxin and the perillaldehyde are both biogenic pesticides and are environment-friendly. The composition can be used for preventing and treating tomato gray mold after being used alone, and has remarkable synergistic effect after being used in combination; can effectively reduce the dosage of active ingredients and slow down the generation of drug resistance.
Detailed Description
The present invention will be further explained with reference to specific embodiments.
Example 1 indoor virulence determination of polyoxin and perillaldehyde on tomato gray mold
Testing germs: collecting and separating tomato gray mold pathogen in field for storage.
The test method comprises the following steps: the measurement was carried out by the hyphal growth rate method. On the basis of the preliminary experiment, 5 drug-containing culture media with different gradient concentrations are prepared and set as controls. Inoculating the fungus cake with diameter of 5mm of Botrytis cinerea to the center of the culture medium containing medicine, and culturing for 5d for 4 times. The colony diameter of each treatment was measured by the cross method, and the inhibition rate was calculated.
Inhibition = (control colony diameter-treatment colony diameter)/control colony diameter × 100%; the diameters in the formula are all increasing diameters.
The evaluation method comprises the following steps: the combination of the active ingredients was evaluated according to the Sun cloud Peel method. Antagonism when CTC < 80; when CTC is more than 120, the effect is synergistic; when the CTC is more than or equal to 80 and less than or equal to 120, the additive effect is obtained.
And (3) measuring results: as shown in Table 1, both polyoxin and perillaldehyde can be used for preventing and treating tomato gray mold independently, and compared with perillaldehyde, polyoxin has higher preventing and treating effect on tomato gray mold, and EC50 is 12.40 mg/L. After the polyoxin and the perillaldehyde are compounded and used, the composition shows different combined effects on the tomato gray mold under different proportioning conditions. When the quantity is more: the mass ratio of the purple is 10:1-1: the composition shows obvious synergistic effect on tomato gray mold at 1 time, and particularly, the composition has the following advantages: when the mass ratio of the purple is 5:1, the CTC value is 148.95, and the purple has a synergistic effect. The polyoxin and the perillaldehyde are both biogenic pesticides and are environment-friendly. The composition can be used for preventing and treating tomato gray mold after being used alone, and has remarkable synergistic effect after being used in combination; can effectively reduce the dosage of active ingredients and slow down the generation of drug resistance.
