Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a sterilizing composition for preventing and treating passion fruit stem basal rot.
Background
Passion fruit is also called passion fruit and passion fruit, which is a tropical fruit and has the American name of "king of beverage". The stem basal rot is one of the main diseases of passion fruit, and mostly occurs at the stem basal part of the plant, which is 5cm to 15cm away from the ground, after the passion fruit is infected at the seedling stage, the stem basal part is dark brown speck, the stem basal layer is gradually softened and then decayed, brown specks are generated, the leaves of the plant are withered, yellow and fall off, the branches and tendrils are slowly withered and even the plant is withered, and the plant is a destructive disease in the passion fruit planting process. There are various pathogens causing passion fruit stem rot, including fusarium, fusarium oxysporum, phytophthora, trichoderma, and new trichoderma species.
In the passion fruit production process, medicaments such as mancozeb, carbendazim, prochloraz, difenoconazole, tebuconazole, fludioxonil, thiophanate methyl and the like can be used for preventing and treating passion fruit stem rot. However, with the long-term use of these agents, pathogenic bacteria have developed a degree of resistance to them, resulting in a decrease in control effect. The application dosage of the medicament is blindly increased, the control effect can be improved only in a short time, and meanwhile, the negative effects of accelerating the development of drug resistance, increasing pesticide residues and the like are also present.
The trifluoropyridinamine is a novel SDHI bactericide developed in 2013 of Zhengda company, and has the English name: cycloobutrifluram, molecular formula: c (C) 17 H 13 Cl 2 F 3 N 2 O has the following structural formula:
as a member of the SDHI class of bactericides, trifluoropyridinamine is also an inhibitor of pathogenic bacteria respiration, inhibiting mitochondrial function by interfering with tricarboxylic acid circulation on respiratory electron transfer chain complex II, preventing it from generating energy, inhibiting pathogenic bacteria growth, and ultimately leading to its death. In addition, the trifluoropyridinamine can also paralyze nematode larvae through interference of respiration, thereby leading to energy exhaustion in cells and inhibiting egg hatching. The trifluoropyridinamine has broad spectrum and high efficiency, can provide durable protection effect for crops, and prevents the crops from being damaged by nematodes and soil-borne diseases which are difficult to find but extremely damaging, especially fusarium.
Although trifluoropyridinamine has the advantages, the action mechanism of the trifluoropyridinamine on pathogenic bacteria is single, and if the trifluoropyridinamine is singly used for a long time, the higher drug resistance risk exists. The compounding of different medicaments is an effective and convenient way for developing a novel medicament, improving the target control effect and delaying the generation of drug resistance. At present, no report on the compounding of the triflumamid and fludioxonil or trifloxystrobin is seen.
Disclosure of Invention
The invention aims to provide a bactericidal composition for preventing and controlling passion fruit stem basal rot, which aims to solve the problem that pathogenic bacteria have generated a certain degree of drug resistance to the passion fruit stem basal rot with long-term use of a medicament, so that the preventing and controlling effect is reduced. The application dosage of the medicament is blindly increased, the control effect can be improved only in a short time, and the problems of accelerating the development of drug resistance, increasing pesticide residues and other negative effects are also solved.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the active ingredients of the bactericidal composition are compounded by the triflumamid and fludioxonil or trifloxystrobin.
More specifically, the mass ratio of the trifluoropyridinamine to fludioxonil is 1-7:15-1.
More specifically, the mass ratio of the triflumamid to the orysastrobin is 1-20:20-1.
The invention also provides application of the bactericidal composition in preventing and treating passion fruit stem basal rot.
More specifically, the passion fruit stem basal rot is caused by fusarium putrescens.
Compared with the prior art, the invention has the following beneficial effects:
(1) The bactericidal composition provided by the invention has synergistic effect on inhibiting the growth of fusarium mycelia of passion fruit stem rot pathogen, can improve the control effect on passion fruit stem rot, is beneficial to reducing the application amount of active ingredients, and reduces the control cost and environmental pressure.
(2) The bactericidal composition can delay the generation and development of drug resistance of pathogenic bacteria and reduce the risk of drug resistance by using a single effective component.
Detailed Description
The following description of the embodiments of the present invention will be apparent from, and is intended to provide a thorough description of, the embodiments of the present invention, and not a complete description of, the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, are intended to fall within the scope of the present invention.
Examples: screening of passion fruit stem rot disease control medicament
1. Test strain
Collecting disease samples from the planting land of passion fruit, separating and purifying pathogenic bacteria in a laboratory by adopting a tissue separation method, identifying the passion fruit stem base rot pathogenic bacteria as Fusarium solani, and storing the Fusarium solani on a PDA culture medium.
2. Test agent
86% of trifluopicolamine (Switzerland is reaching crop protection Co., ltd.), 98% of fludioxonil (Shanghai He medical Co., ltd.), 98% of orysastrobin (Hubei Shuangalling Co., ltd.).
3. Test methods (cf. Section 2. Methods for test criteria for biological tests in pesticide laboratory: petri dish method for inhibition of growth of mycelium of pathogenic fungi).
Dissolving the test agent with dimethyl sulfoxide, diluting with 0.1% Tween-80 aqueous solution to obtain single-agent mother solution, setting multiple groups of ratios, and setting 5 mass concentration gradients for each single-agent mother solution and ratio mixture according to an equal ratio method. Adding 9mL of pre-melted PDA culture medium into a sterile conical flask, sequentially quantitatively sucking 1mL of liquid medicine from low concentration to high concentration, respectively adding into the conical flask, shaking uniformly, pouring into a culture dish with the diameter of 9cm, and preparing a medicine-containing flat plate with corresponding concentration; treatments without agent were also included as blank, and 9 replicates were set for each treatment. Cutting bacterial cakes with the diameter of 5mm from the colony edge of the strain to be tested by using a puncher, inoculating the bacterial cakes to the centers of a medicine-containing flat plate and a blank control flat plate, covering a dish cover, placing the dish cover in a constant temperature oven at 28 ℃ for culturing for 7d, measuring the colony diameter by using a crisscross method, and calculating the hypha growth inhibition rate of different treatments.
4. Data analysis: performing data statistical analysis by DPS software, and linearly regressing with the value of the disinfectant concentration logarithmic value x and the value of the corresponding hypha growth inhibition rate logarithmic value y to obtain a virulence regression equation and the virulence EC of the medicament on the target pathogen 50 Values and co-toxicity coefficients (CTCs) were calculated according to the grand cloud Pei method.
