Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly belongs to a bactericidal composition for preventing and treating wheat powdery mildew.
Background
Wheat powdery mildew is a worldwide fungal disease caused by powdery mildew of Poaceae and occurring on wheat, and occurs in wheat production areas in China. Leaves are mainly damaged, and in severe cases, leaf sheaths, stalks and ears are all infected, so that the normal growth of wheat and the yield of wheat are influenced. Chemical agents have been the main means of controlling the development of wheat powdery mildew, and commonly used bactericides include: triadimefon, tebuconazole, propiconazole, azoxystrobin, carbendazim and the like. However, due to the unreasonable application of conventional chemical agents, the problems of pesticide residues and the risk of drug resistance have increased year by year, and for example, powdery mildew has been reported to have developed a higher resistance to triadimefon. Therefore, there is a need to develop new preventive agents.
The physcion is a novel botanical fungicide independently developed in China, is a botanical pesticide extracted from roots and stems of rhubarb of Chinese herbal medicine family, belongs to anthraquinone high-activity antibacterial compounds, is widely researched and applied in the field of medicine, and has gradually increased application in the aspect of pesticide in recent years. The physcion interferes the biosynthesis of chitin in the cell wall of pathogenic fungi, so that the germ tube and mycelium are locally enlarged and broken, the cell contents are discharged, and the death is caused. The physcion has the advantages of high activity and long lasting period, has special effect on powdery mildew of vegetables, and can prevent downy mildew, gray mold and anthracnose. The action mechanism is unique, and the bactericide has the effect of inducing disease resistance and has no cross resistance with other bactericides.
The combination with synergistic effect is prepared by compounding and screening different pesticide varieties, so that the influence on the environment can be reduced, the development of drug resistance of pathogenic bacteria can be delayed, and the pesticide composition is an economic and effective means for preventing and treating diseases and developing novel medicaments. CN201510725660.0 discloses a pesticide composition containing physcion and kasugamycin, and specifically discloses that the content of physcion and kasugamycin is in a ratio of 0.1:10-2:0.5 weight ratio has synergistic effect on pathogenic bacteria such as cucumber anthracnose, rice blast and the like. In addition, CN201510011364.4 also discloses a botanical synergistic compound bactericide and application thereof, and particularly discloses that berberine and physcion can be used for preventing and treating agricultural diseases such as powdery mildew, gray mold, anthracnose, downy mildew, phytophthora root rot, brown rot and phyllostachys leaf blight after being compounded. However, at present, no report about the compounding of physcion and validamycin or natamycin is available yet.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Disclosure of Invention
The invention aims to provide a bactericidal composition for preventing and treating wheat powdery mildew, which has a synergistic effect on pathogenic bacteria of wheat powdery mildew, can improve the prevention and treatment effect on wheat powdery mildew and provides support for developing novel prevention and treatment agents.
In order to achieve the purpose, the invention provides the following technical scheme:
the effective components of the bactericidal composition for preventing and treating wheat powdery mildew are compounded by physcion and validamycin or natamycin.
Preferably, the mass ratio of the physcion to the validamycin is 1-40:19-1.
Preferably, the mass ratio of the physcion to the natamycin is 1-9:9-1.
The invention also provides a bactericidal agent which comprises the bactericidal composition for preventing and treating wheat powdery mildew and auxiliary components, wherein the auxiliary components are selected from one or more of wetting agent, dispersing agent, cosolvent, preservative, defoaming agent, antifreezing agent, tackifier and filler.
Compared with the prior art, the invention has the following beneficial effects:
(1) After the physcion and the validamycin or the natamycin are compounded in the bactericidal composition, the bactericidal composition has a synergistic effect on wheat powdery mildew, can improve the control effect on wheat powdery mildew, can reduce the application dosage of pesticide on the basis, realizes time reduction and synergism, and is beneficial to reducing pesticide residues.
(2) After the physcion and the validamycin or the natamycin in the bactericidal composition are compounded, the development of drug resistance of pathogenic bacteria can be delayed, and the update cycle of a control medicament is prolonged.
Detailed Description
The invention will be better understood from the following examples. However, it is easily understood by those skilled in the art that the descriptions of the embodiments are only for illustrating the present invention and should not be construed as limiting the present invention as detailed in the claims.
Examples: screening of preventive agents
1. Pathogenic bacteria for test
Washing fresh spores of wheat leaves full of Erysiphe cichoracearum with purified water containing 0.05% Tween-80, filtering with double-layer gauze, and making into 1 × 10 5 Suspension of spores/mL for use;
2. test work: performing pot culture to obtain 2-4 wheat seedlings of Bainong 207 in the true leaf stage, wherein 10 wheat seedlings are planted in each pot and numbered for later use.
3. Reagent for testing
98% of physcion technical product, 99% of validamycin technical product and 99% of natamycin technical product, which are all sold in the market.
Dissolving the test reagent with dimethyl sulfoxide, diluting with 0.1% Tween-80 water solution to obtain single mother liquid, and setting multiple groups of mixture ratios, wherein each single agent and mixture ratio have 5 mass concentration gradients by equal ratio method.
4. Test method (refer to NY/T1156.4-2008 pesticide laboratory bioassay Standard Fungicide part 4: experimental potting method for preventing and treating wheat powdery mildew)
Spray inoculating the test sample with spore suspension 24h before the treatment of the medicament; after natural air drying, uniformly spraying the liquid medicine on the leaf surfaces of the tested crops until the leaves are completely wet, treating 3 pots each, and setting the treatment containing only 0.1% of Tween-80 as a blank control; and after natural air drying, moving to a constant temperature chamber, continuously culturing for 10 days at the temperature of 25 ℃, investigating the disease condition of each treatment in a grading manner, randomly selecting 5 plants in each pot, and investigating all leaves. Calculating disease index and preventing and treating effect of each treatment. The classification criteria are shown in Table 1.
TABLE 1 evaluation of disease levels
5. And (3) data analysis: DPS software is adopted to carry out data statistical analysis, linear regression is carried out by taking the logarithm value of the concentration of the bactericide as x and the corresponding control efficiency value as y, and a toxicity regression equation and the toxicity EC of the medicament on the target germs are obtained 50 Value, and co-toxicity coefficient (CTC) was calculated according to the grand cloud method.
6. Measurement results
And evaluating the synergism of the medicament according to the calculated co-toxicity coefficient (CTC), wherein the CTC is not more than 80 as an antagonistic action, the CTC is more than 80 and less than 120 as an additive action, and the CTC is not less than 120 as a synergistic action, and the results are shown in tables 2-3.

| Physcion 40: validamycin 1 | 9.1539 | 122.8700 | 98.2319 | 125.0816 |
As shown in Table 2, after the physcion and the validamycin are compounded, the mass ratio of the physcion to the validamycin is 1-3: the co-toxicity coefficient to erysiphe graminis within 40-1 is more than 120, and the synergistic effect is shown. Especially when the mass ratio is 7.5: when 1, the co-toxicity coefficient reaches 523.4148, and the synergistic effect is particularly remarkable.
