[0012] The tobacco bud inhibitor based on fatty alcohol as previously described has a bud inhibition effect on tobacco of 80% or more.
[0013] Compared with the prior art, the present application has obvious advantages and beneficial effects. By means of the above technical scheme, the present application can achieve considerable technical progress and practicability, and has wide utilization value, and at least has the following advantages: The tobacco bud inhibitor of the present application uses n-octanol and n-decanol as effective components, polyoxyethylene 40 hydrogenated castor oil as an emulsifier, and anhydrous ethanol as a solvent, and is a bud inhibitor in the form of an emulsifiable concentrate. The synergistic effect of n-octanol and n-decanol can efficiently inhibit buds, which conforms to the concept of green bud inhibition and avoids the problem of excessive chemical pesticide residues in tobacco caused by the use of chemical bud inhibitors. The use of polyoxyethylene 40 hydrogenated castor oil as an emulsifier can reduce the interfacial tension of the product, so that the product forms a uniform and fine emulsion, thereby the product has good stability, prevents separation, precipitation or precipitation, and ensures that the bud inhibitor remains in a uniform state during storage, transportation and use. When used, it can better spread on the surface of the axillary bud, improve the absorption efficiency of the effective components. In addition, the use of polyoxyethylene 40 hydrogenated castor oil as an emulsifier can also disperse the effective components in the bud inhibitor into small liquid beads, increase the contact area with the tobacco axillary bud, and enhance the efficacy. The emulsion structure formed by the bud inhibitor can delay the release speed of the effective components and prolong the bud inhibition time. It has been verified through experiments that polyoxyethylene 40 hydrogenated castor oil as an emulsifier has the best effect.
[0014] The formula is reasonable, the bud inhibition effect is good, the effective period is long, and the tobacco bud inhibitor prepared in the form of emulsifiable concentrate does not contain components such as dimethenamid, butachlor and fluazinam. Compared with the chemical bud inhibitor 25% fluazinam emulsifiable concentrate, the tobacco bud inhibitor based on fatty alcohol has better bud inhibition effect on tobacco, and can achieve 80% bud inhibition effect, which is much higher than that of the chemical bud inhibitor 25% fluazinam emulsifiable concentrate. Therefore, the tobacco bud inhibitor based on fatty alcohol not only significantly improves the bud inhibition effect, but also avoids the problem of excessive chemical pesticide residues in tobacco caused by the use of chemical bud inhibitors.

If the original drug is not dissolved, continue to add solvent. If the solvent is added to 2 g and the original drug is still mostly not dissolved, the solvent is eliminated. The dissolved and stable sample is stored at 0°C for 4 h, then taken out and restored to room temperature, and whether there is crystallization, turbidity, and layering is observed.

Each emulsifier is repeated 3 times, and the evaluation level of emulsion effect is referred to Table 2, and 1 and 2 levels are judged as qualified.
[0025] Preparation of standard hard water: 0.304 g of anhydrous calcium chloride and 0.139 g of magnesium chloride with crystalline water are weighed into a 1000 mL beaker, 600 mL of distilled water is added to dissolve, then poured into a 1000 mL volumetric flask, the beaker is rinsed with 300 mL of distilled water, the rinse is also poured into the volumetric flask, and the volume is adjusted to the mark with distilled water, and shaken well for use. The hardness of the standard hard water is 342 mg / L calculated as calcium carbonate. -1 .
[0026] Table 2. Relationship between the dispersion state, emulsification state and evaluation level of the experimental sample in water (2.2) Emulsion stability judgment standard: according to the judgment standard of table 2, the qualified sample is diluted 200 times with standard hard water, and then placed in a 30±2°C water bath for 1h. The emulsion stability is detected, and the GB / T 1603-2001 (current, applicable to emulsion, microemulsion, water emulsion) is referred to as qualified without oil on top and no sediment on bottom.
[0027] (2.3) Cold storage judgment standard: according to the relevant standards of "Pesticide Low Temperature Stability Determination Method" (GB / T19137-2003), 10mL of experimental sample is sealed in a glass container and stored at 0~2°C for 7 days. After taking out, its state after cold storage is observed immediately. If the sample after cold storage has no freezing, no stratification and no precipitation, it is determined to be qualified. If any of the above conditions occurs after cold storage, the experimental sample is placed in a normal temperature (20~25°C) environment, and the time required for its natural recovery to the state before cold storage is recorded. If it recovers to the state before cold storage within 2 hours, it is also determined to be qualified.
[0028] (2.4) Hot storage judgment standard: according to the relevant standards of "Pesticide Hot Storage Stability Determination Method" (GB / T19136-2021), 10mL of experimental sample is sealed in a glass container and stored in a 54°C constant temperature box for 14 days. After taking out, the sample is observed for oil separation and stratification, and the decomposition rate of n-octanol and n-decanol is detected within 24h. If there is no oil separation, no stratification and the decomposition rate of n-octanol and n-decanol is less than 5% after hot storage, it is determined to be qualified. The decomposition rate of n-octanol and n-decanol can be detected by gas chromatography mass spectrometry.

[0038] It should be noted that, in the above examples, when the air temperature is high (the room temperature is above 20℃), n-decanol and dodecanol are in liquid state, and thus heating is not required during preparation. If the air temperature is low in winter, n-decanol and dodecanol can be heated to be in liquid state, and then mixed and prepared.
[0039] (4) Field test The tobacco bud inhibitor of Example 1 is subjected to a field test, and compared with a chemical bud inhibitor 25% flumetralin emulsion, to verify the bud inhibition effect of the tobacco bud inhibitor based on fatty alcohol. The 25% flumetralin emulsion is purchased, and the mass percentage content of flumetralin is 25%.
[0040] Tested crop: flue-cured tobacco variety Zhongyan 100 (selected by Luoyang Tobacco Monopoly Bureau, provided by Duqu Village, Gaocun Town, Luoyang City).
[0041] Test site: Shangdian Town, Ruyang County, Luoyang City, Henan Province (north latitude 34°11', east longitude 112°43'), average elevation 355 meters.
[0042] The field test was designed for 3 test groups, 100 tobacco plants in each test group, spraying pesticide as treatment group (T1 and T2), spraying water as control group (CK), and the design scheme of 3 test groups is shown in Table 6.
[0043] Table 6. Design scheme of 3 test groups Spraying scheme: The bud inhibition agent is diluted according to the field spraying amount (it should be noted that the dilution multiple of 25% flumetralin emulsion on the pesticide instruction is 350 times, but in the field test of the present application, it is diluted by 100 times for test, that is, the use concentration has been expanded), in each test group, about 50% of the tobacco plants are topped when the first central flower opens, and the pesticide is applied within 24 hours, and the axillary buds exceeding 2 cm are removed. The spraying method is cup spraying, and the dosage of the diluted pesticide per plant is 25 mL.
[0044] Measurement: On the 10th day, 20th day, 30th day and 40th day after spraying, 15 tobacco plants with consistent growth were selected at fixed points in each test group area, the number of effective axillary buds (axillary bud length greater than 2 cm) of the 15 tobacco plants was counted, and the bud inhibition rate was calculated. After the last (40th day) statistics, the effective axillary buds of 100 tobacco plants in each test group were all removed and weighed, and the bud inhibition effect was calculated.
[0045] Bud inhibition rate calculation formula: Bud inhibition rate (%) = [(number of effective axillary buds of control group - number of effective axillary buds of treatment group) / number of effective axillary buds of control group] x 100%.
[0046] Bud inhibition effect calculation formula: Bud inhibition effect (%) = [(fresh weight of effective axillary buds of control group - fresh weight of effective axillary buds of treatment group) / fresh weight of effective axillary buds of control group] x 100%.
[0047] The test results are shown in Table 7 below.
[0048] Table 7. Bud inhibition rate and bud inhibition effect of treatment group and control group Figure 2 It is a physical photo of tobacco leaf axillary buds of CK control group on the 10th day after spraying, and the circle in the figure is the axillary bud. Figure 3It is the physical picture of tobacco leaf of T2 treatment group on the 10th day after application. It can be seen that the bud inhibition agent of Example 1 has a significant inhibitory effect on tobacco axillary buds after application.
[0049] The above test results show that compared with the dilution ratio recommended in the 25% flumetralin emulsion formulation specification, although the aforementioned field test has expanded its use concentration, which indirectly enhances its efficacy, but compared with the fat alcohol-based bud inhibition agent of the present application, the bud inhibition effect of the 25% flumetralin emulsion agent is still not significant enough, and because the use concentration of 25% flumetralin emulsion has been expanded, it further increases the risk of exceeding the chemical pesticide residue of tobacco leaves. Therefore, compared with chemical bud inhibition agents, the fat alcohol-based tobacco bud inhibition agent of the present application not only significantly improves the bud inhibition effect, but also avoids the problem of exceeding the chemical pesticide residue of tobacco leaves caused by using chemical bud inhibition agents.
[0050] The above is only an embodiment of the present application, and does not limit the present application in any form. The present application can also have other forms of embodiments according to the above structure and function, and will not be listed one by one. Therefore, any skilled person in the art, without departing from the scope of the technical solutions of the present application, according to the technical essence of the present application, any simple modification, equivalent change and modification of the above embodiments, still belongs to the scope of the technical solutions of the present application.
