[0076] Example

[0077] The preparation process of surfactin used in the following examples is as follows:

[0078] Pick a single colony of Bacillus subtilis (for the construction method of a single colony of Bacillus subtilis, see CN201810865295.7), inoculate it into LB liquid culture medium, and culture it at 37°C and 200rpm for 16 hours to obtain a seed solution, which is inoculated into a fermentation medium shake flask at a ratio of 5%. After culturing at 37°C and 200rpm for 2 to 6 hours, 1mM IPTG is added, and the culture is continued for 2 days to obtain an initial fermentation liquid containing surfactin.

[0079] The composition of the initial fermentation medium used is: 30-100 g / L of carbohydrates, 10-50 g / L of inorganic nitrogen source, 0.5-3 g / L of organic nitrogen source, 0.1-1 g / L of KH2PO4, 0.5-0.3 g / L of Na2HPO4·12H2O, 0.002-0.01 g / L of CaCl2, 0.002-0.01 g / L of MnSO4·H2O, 0.002-0.01 g / L of FeSO4·7H2O, pH 6.5-7.5, and 0.01-20 wt% of fermentation additives (silicon defoaming agent, polysaccharide, amino acid or its derivatives, oligopeptide, phospholipid, glycolipid, and / or fatty acid or its derivatives).

[0080] The pH of the initial fermentation broth is adjusted to between 6.0 and 6.5, and the solution is allowed to stand overnight at 4°C to allow the substances in the solution to completely precipitate or to accelerate its sedimentation by slight stirring, and finally the product obtained by centrifugation is the fermentation broth. The method disclosed in CN105400784A is used to detect the content of surfactant in the fermentation broth. Specifically: 1 mL of fermentation broth is centrifuged at 12000 rpm for 1 minute, 100 μL of supernatant is added to 1900 μL of deionized water, mixed, and analyzed by HPLC after filtering through a 0.22 μm filter membrane. The mobile phase for HPLC analysis is methanol and water in a ratio of 85 / 15, the flow rate is 1 mL / min, the chromatographic column is a C18-ODS reverse phase chromatographic column, the column temperature is 40°C, the ultraviolet detector, and the detection wavelength is 205 nm.

[0081] The test showed that the content of surfactin in the fermentation broth was 30%. The pH of the fermentation broth was adjusted to acidic, and the surfactin formed a precipitate. After solid-liquid separation, the solid part was taken and dried to obtain a surfactin-containing product. The powder product was obtained by cold purification and freeze drying, and the content of surfactin was measured to be 95wt%-99.99wt%.

[0158] Test Example 2

[0159] 1. Purpose of the test

[0160] The synergistic effect of the pesticide adjuvant in the examples on 10% refined glufosinate ammonium soluble solution was evaluated through experiments.

[0161] 2. Test basis

[0162] This test project is based on the "Quality Management Standards for Pesticide Registration Tests" and is carried out with reference to the "Quality Management Standards for Pesticide Registration Field Efficacy Tests" (NY / T2885-2016) and the "Guidelines for Pesticide Field Efficacy Tests (I) Herbicides for Control of Weeds in Non-arable Land" (GB / T17980.51-2000).

[0163] 3. Selection of test subjects, crops and varieties

[0164] Test object: Weeds in non-cultivated land (dominant weeds are cleavers, common vetch, and thorny weeds, and other weeds include reeds, white grass, philadelphus philoxeroides, wild stork, etc.)

[0165] The experimental design is shown in Table 3. The blank control refers to the control without any drug.

[0168] Among them, for the dosage of the preparation (times of liquid + mL / 667m 2 ), taking treatment 2 as an example, times the liquid + mL / 667m 2 It refers to a mixed solution of the sample in Example 1 diluted 1000 times + 10% refined glufosinate ammonium soluble solution at a dosage of 300 ml per mu.

[0169] 4. Repetitions

[0170] Each treatment was replicated three times, for a total of 21 plots.

[0171] 5. Frequency of application

[0172] 1 time

[0173] 6. Crop growth period

[0174] Weeds are in their active growth phase.

[0175] 7. Application capacity

[0176] Water consumption: 450L / hm 2

[0177] The test results are shown in Table 4.

[0178] Table 4 Field efficacy test results of pesticide adjuvants on 10% refined glufosinate ammonium soluble solution

[0179]

[0180] Note: The letters in the table indicate significant differences at the 0.05 level.

[0181] Among them, the plant control efficacy investigates the total number of surviving weeds of each species, reflecting the killing effect of the pesticide on weeds; the fresh weight control efficacy investigates the weight of each surviving weed, which can also reflect the inhibitory effect of the pesticide on the growth of weeds.

[0182] The formula for calculating the protective effect is: E = 100 × (CT) / C

[0183] Where: E is the number of plants / fresh weight of weed control effect, C is the number of plants / weight of weeds in the control area, and T is the number of plants / weight of weeds in the treatment area.

[0184] Conclusion: From Table 4, it can be seen that the pesticide adjuvant can effectively improve the control effect of 10% refined glufosinate ammonium soluble solution on non-arable weeds, accelerate the control speed of 10% refined glufosinate ammonium soluble solution on weeds, and the pesticide adjuvant has the effect of improving the weed control effect in the concentration range of 0.01%-50%. It can be seen from Treatments 5 and 6 that reducing the amount of 10% refined glufosinate ammonium soluble solution can also make the pesticide achieve the same effect, thereby improving the utilization rate of the pesticide.

[0202] Conclusion: From Table 6, we can see that the mortality rate 6 hours after the same treatment is significantly lower than the mortality rate 24 hours after the same treatment; and the pesticide adjuvant has an improved insecticidal effect in the concentration range of 0.01%-50%; through treatments six and seven, we can see that reducing the amount of refined glufosinate ammonium soluble solution by 10% can also achieve the same effect, thereby improving the utilization rate of pesticides.

[0203] Test Example 4

[0204] 1. Purpose of the experiment: To verify whether pesticide adjuvants have a synergistic effect on 30% cyhalofop-butyl EC (conventional commercial product) and the degree of synergism.

[0205] 2. Test targets and crops

[0210]

[0211]

[0212] For the dosage (ml, g / mu), taking Treatment 2 as an example, 8 ml of the sample of Example 1 + 100 g of 30% cyhalofop-butyl EC was applied per mu.

[0213] 4. Calculation method of prevention effectiveness

[0214] According to the formula shown in GB / 7980.44-2000

[0215] Control effect (%) = (CK-PT) * 100 / CK

[0216] Where: PT is the number or fresh weight of remaining grass in the treatment area, CK is the number or fresh weight of living grass in the blank control area

[0217] 5. Data statistics and analysis methods

[0218] The survey data were analyzed using DPS (v9.50) statistical software. The control effects were analyzed using Duncan's new multiple range method and arcsine square root transformation. The same letters indicate no significant difference among treatments, p = 0.05.

[0219] The test results are shown in Table 8.

[0224] Among them, letters indicate that those with the same letter mark have no significant difference, and those with different letter marks have significant difference.

[0225] Conclusion: It can be seen from Table 8 that when pesticide adjuvants with different lipid components are tank-mixed with the conventional agent 30% cyhalofop-butyl, they can accelerate the death rate and control effect of barnyard grass, and the weed control effect of the pesticide adjuvant is more significant in the concentration range of 0.01%-50%.
