Detailed Description
The following specific examples are intended to illustrate the invention in further detail, but the invention is by no means limited to these examples. In the examples, the proportions of the components are by weight.
Indoor biological activity assay
Example 1 determination of the synergistic Effect of a composition containing Compound I on Tetranychus cinnabarinus
Test subjects: tetranychus cinnabarinus (Tetranychus cinnabarinus Boisdival), adult mites, and indoor-reared sensitive strains.
And (3) testing conditions are as follows: temperature: 24-26 ℃, relative humidity: 60%, illumination: l: D ═ 14:10
Preparing a liquid medicine: according to different test requirements, accurately weighing test samples (the compositions and the original drugs with different proportions in the invention) by using an electronic analytical balance respectively, wherein the original drug is dissolved by acetone and diluted into liquid medicine with certain concentration by using 0.1 percent of Tween 80 water according to the test design dose.
The test method comprises the following steps: the activity of tetranychus cinnabarinus on adult tetranychus cinnabarinus is determined by a potted seedling spraying method. Firstly, 40-60 adult tetranychus cinnabarinus with consistent size are grafted to kidney bean seedlings (one true leaf is reserved) in a first true leaf development period, and the base number is counted after the adult tetranychus cinnabarinus is stabilized; then, the test specimens were treated with the liquid medicine by the Airbrush method, 1.5mL per specimen, and a blank control was set.
And after natural drying in the shade, placing the treated test material in an observation chamber, adjusting the temperature, humidity and illumination of the observation chamber as required, investigating the number of live mites after 72 hours, and calculating the mortality. Evaluation was carried out by the Bliss method, which is one of the classical methods for evaluating the effect of mixtures. Bliss, based on its proposed concept of independent combined action, believes that the theoretical mortality rate P of a combination of insecticides and acaricides can be calculated by the following formula:
P=Pm+Pn(1-Pm)
Pmis the mortality (%) of the target at a concentration m of the first active ingredient; pnThe mortality (%) of the target at a concentration of n is used for the second active component.
If the actual mortality rate of the target after the two active components are mixed at a certain concentration is greater than the theoretical mortality rate P, the two active components are judged to have synergistic effect when being mixed at a set concentration, otherwise, the two active components are antagonistic.
The results are shown in Table 1.

Figure BDA0001985415010000041
Example 2 indoor Activity assay of compositions containing Compound I against Tetranychus cinnabarinus
The synergistic effect measurement effect data show that the composition formed by mixing the compound I and 2 medicaments such as the spirodiclofen and the like has an obvious synergistic effect on tetranychus cinnabarinus adults, and further the composition formed by the compound I, the spirodiclofen and the spirotetramat in a test of 5:1-1:5 is used for indoor activity measurement.
Test targets: tetranychus cinnabarinus (Boisdivaval) becomes a sensitive strain which is bred indoors.
Preparing a liquid medicine: according to different test requirements, accurately weighing the test samples by using an electronic analytical balance, dissolving the original medicine by using acetone, and diluting the dissolved original medicine into a series of liquid medicines (the composition of the invention) with a certain concentration gradient by using 0.1 percent of Tween 80 water according to the test design dosage.
The test method comprises the following steps: the activity of tetranychus cinnabarinus on adult tetranychus cinnabarinus is determined by a potted seedling spraying method. Firstly, inoculating tetranychus cinnabarinus with consistent size to kidney bean seedlings (one true leaf is reserved) in a first true leaf flattening period, and counting the base number after the tetranychus cinnabarinus is stabilized; then uniformly spraying the liquid medicine by an Airbrush method according to the sequence of test design from low dose to high dose, wherein each plant is 1.5mL, and the treatment is repeated for 4 times, and a blank control is additionally arranged.
And (3) placing the treated test material in an observation chamber, wherein the temperature, the humidity and the illumination of the observation chamber can be adjusted as required. The number of dead and live mites was investigated after 72 hours. Calculating corrected mortality by abbott formula, performing statistical analysis by DPS data processing software, and calculating toxicity regression equation and LC for each single agent and different mixture ratio50The value and the 95% confidence limit, and the cotoxicity coefficient of each proportion is calculated by a Sun Yun Pei (Sun y-p) method, and the blending effect is evaluated.
The co-toxicity coefficient (CTC value) of the mixture was calculated according to the following formula:
Figure BDA0001985415010000051
in the formula: actually measuring a toxicity index of the ATI-mixed agent; LC of S-Standard drug50(ii) a LC of M-mixtures50
TTI=TIA×PA+TIB×PB
In the formula: TTI-theoretical virulence index of the mixture; TIA-A agent virulence index; the percentage content of the PA-A medicament in the mixture; TIB-B agent virulence index; the percentage content of the PB-B medicament in the mixture.
Figure BDA0001985415010000052
In the formula: CTC-co-toxicity coefficient; actually measuring a toxicity index of the ATI-mixed agent; TTI-mixture theory virulence index.
Co-toxicity coefficient (CTC) of the combination: CTC is more than or equal to 120 and shows synergistic effect; CTC is less than or equal to 80 and shows antagonism; 80< CTC <120 shows additive effects.
And, LC of the composition50LC with a value less than one or two of the single doses50By value, it is meant that the composition is administered in a dose less than one or both of the single doses, while achieving the same effect (mortality rate of 50%).
The test results are shown in tables 2 and 3.

Table 3: indoor combined toxicity determination result of compound I-spirotetramat on tetranychus cinnabarinus
Figure BDA0001985415010000061
The data show that the compound I, spirodiclofen is matched with 1 pair of tetranychus cinnabarinus LC50Value of 0.44mg/L, single dose LC50Values of 0.48mg/L and 6.31mg/L, respectively, mean that the dosage of the composition (0.44mg/L) is less than the dosage of one or both of the single doses (0.48mg/L and 6.31mg/L) at the same effect (mortality of 50%); in addition, the control effect of the composition is higher than the theoretical effect of two single agents to different degrees from the definition of co-toxicity coefficient; due to field dosage and indoor LC50The values are positively correlated, so the field dosage of the composition is correspondingly reduced, thereby reducing the use cost and reducing the environmental pollution.
