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 compositions containing Compound I on Tetranychus cinnabarinus
Test subjects: tetranychus cinnabarinus (Tetranychus cinnabarinus Boisdival), adult mites, a sensitive strain raised indoors.
And (3) testing conditions are as follows: temperature: 24-26 ℃, relative humidity: 60%, illumination: l: D =14
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 Tween 80 water according to the test design dose.
The test method comprises the following steps: the activity of the tetranychus cinnabarinus on adult tetranychus cinnabarinus is determined by a potted seedling spraying method. Firstly, grafting 40-60 tetranychus cinnabarinus adults with consistent size onto kidney bean seedlings (one true leaf is remained) in a first true leaf flattening period, and counting the base number after the tetranychus cinnabarinus adults are stable; then, the test specimens were treated with the liquid medicine by the Airbrush method, and each specimen was treated with 1.5mL of blank control.
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 insecticidal and acaricidal agents can be calculated by the following formula:
P＝P m +P n (1-P m )
P m is the mortality (%) of the target of the first active ingredient at a concentration m; p is n The mortality (%) of the target at a concentration n is used for the second active component.
If the actual mortality of the target is greater than the theoretical mortality P after the two active components are mixed at a certain concentration, the two active components are judged to have synergistic effect when being mixed at a set concentration, otherwise, the two active components are judged to have antagonistic effect.
The results are shown in Table 1.
TABLE 1 synergistic effect of compound I and 5 medicaments such as fluazinam on tetranychus cinnabarinus mite formation
Example 2 indoor Activity assay for Tetranychus cinnabarinus Using compositions containing Compound I
According to the synergistic effect test result data, the composition formed by mixing the compound I and 5 medicaments such as fluazinam and the like has an obvious synergistic effect on tetranychus cinnabarinus adults, and the compound I and the fluazinam, pyfluubider or Acynonspy are further used for test 5; the indoor activity assay was performed using the Sun cloud Peel (Sun y-p) method for the composition of compound I and bifenazate in test 4.
Test targets: tetranychus cinnabarinus (Tetranychus cinnabarinus Boisdival) into a mite, a sensitive strain raised indoors.
Preparing a liquid medicine: according to different test requirements, accurately weighing the test samples by using an electronic analytical balance, wherein the original drug is dissolved by acetone and diluted into a series of liquid medicines with a certain concentration gradient by using 0.1% Tween 80 water according to the test design dosage.
The test method comprises the following steps: the activity of the tetranychus cinnabarinus on adult tetranychus cinnabarinus is determined by a potted seedling spraying method. Firstly, adult tetranychus cinnabarinus with consistent size is grafted to kidney bean seedlings (a true leaf is remained) in a first true leaf flattening period, and the base number is counted after the adult tetranychus cinnabarinus is stable; then uniformly spraying the liquid medicine by using an Airbrush spraying 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 ratio 50 The 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:
in the formula: measured toxicity index of ATI-mixture; LC of S-standard medicament 50 A value; LC of M-mixtures 50 The value is obtained.
TTI＝TIA×PA+TIB×PB
In the formula: TTI-mixture theory virulence index; TIA-base:Sub>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.
In the formula: CTC-co-toxicity coefficient; measured toxicity index of ATI-mixture; 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-Ap CTC-s 120 were shown to be additive.
And, LC of the composition 50 LC with a value less than one or two of the single doses 50 By 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 to 5.
Table 2: indoor combined toxicity determination result of compound I-fluazinam on tetranychus cinnabarinus
Table 3: indoor combined toxicity determination result of compound I, bifenazate on tetranychus cinnabarinus
Table 4: indoor combined toxicity determination result of compound I Pyfluzumab on tetranychus cinnabarinus
Table 5: indoor combined toxicity determination result of compound I, acynonspyr on tetranychus cinnabarinus
The data show that the compound I and fluazinam are matched with 1 pair of tetranychus cinnabarinus LC 50 Value of 0.48mg/L, single dose LC 50 Values of 0.52mg/L and 156.40mg/L, respectively, mean that the dosage of the composition (0.48 mg/L) is less than the dosage of one or both of the single doses (0.52 mg/L and 156.40 mg/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 LC 50 The values are positively correlated, so the field dosage of the composition is correspondingly reduced, thereby reducing the use cost and reducing the environmental pollution.
