Firstly, 40-60 tetranychus cinnabarinus adults with the same size are connected to young kidney bean seedlings (one leaf of the young kidney bean is reserved) in a first pair of young leaf flattening periods, and the cardinality is counted after the adult tetranychus cinnabarinus adults are stable; then, the test materials are treated with the medicinal liquid by an Airbrush method, 1.5mL of each strain is used, and a blank control is arranged.
After naturally drying in the shade, placing the treated test material in an observation room, adjusting the temperature, humidity and illumination of the observation room according to the requirements, investigating the number of live mites after 72 hours, and calculating the death rate. The evaluation was performed by the Bliss method, which is one of the classical methods for evaluating the effect of the compound. The theoretical mortality rate P of the combination of insecticides and acaricides according to the independent combined action concept proposed by Bliss can be calculated by the following formula:
P＝P m +P n (1-P m )
P m mortality (%) of the target at a concentration of m for the first active component; p (P) n Mortality (%) of the target at n concentration was 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 mixed at a set concentration, and otherwise, antagonistic effect is judged.
The results are shown in Table 1.
Table 1 synergistic effect of Compound I in combination with isoxazolamide on tetranychus cinnabarinus
EXAMPLE 2 determination of indoor Activity of composition containing Compound I against Tetranychus cinnabarinus
The synergistic effect measurement data show that the composition mixed by the compound I and the isoxazole tebufenozide has obvious synergistic effect on tetranychus cinnabarinus, and the indoor activity measurement is carried out by using the compound I and the isoxazole tebufenozide to test a composition consisting of 4:1-1:4 and using a Sun cloud Peel (Sun y-p) method.
Test target: tetranychus cinnabarinus (Tetranychus cinnabarinus Boisduval) is an adult mite, and is a sensitive strain fed indoors.
Preparing a liquid medicine: according to different test requirements, accurately weighing test samples by using an electronic analytical balance, wherein the raw medicines are dissolved by acetone, and then diluted into a series of liquid medicines with a certain concentration gradient by 0.1% Tween 80 water according to the test design dose.
The test method comprises the following steps: the activity of tetranychus cinnabarinus is measured by a potted seedling spraying method. Firstly, tetranychus cinnabarinus with the same size is connected to young kidney bean seedlings (one leaf of the leaf is reserved) in the first pair of leaf-flattening period, and the cardinality is counted after the tetranychus cinnabarinus is stable; and then uniformly spraying the liquid medicine by an Airbrush spraying method according to the sequence from low dose to high dose of the test design, wherein each strain is 1.5mL, each treatment is repeated for 4 times, and a blank control is additionally arranged.
The treated test material is placed in an observation chamber, and the temperature, humidity and illumination of the observation chamber can be adjusted as required. The number of dead mites and live mites was investigated after 72 hours. Calculating corrected mortality using abbott's formula, using DPS dataThe processing software performs statistical analysis to obtain the virulence regression equation and LC of each single agent to be tested and each mixed agent with different proportions 50 And calculating the co-toxicity coefficient of each proportion by using a grand cloud Pei (Sun y-p) method and evaluating the mixed use effect.
The co-toxicity coefficient (CTC value) of the blend was calculated according to the following formula:
wherein: the ATI-mixed agent actually measures the toxicity index; LC of S-standard agent 50 A value; LC of M-mixture 50 Values.
TTI＝TIA×PA+TIB×PB
Wherein: TTI-mixed agent theoretical virulence index; TIA-A agent virulence index; the percentage of the PA-A agent in the mixture; TIB-B agent virulence index; the PB-B medicament comprises the following components in percentage by weight.
Wherein: CTC-co-toxicity coefficient; the ATI-mixed agent actually measures the toxicity index; TTI-blend theoretical virulence index.
Co-toxicity coefficient (CTC) of the combination agent: CTC is more than or equal to 120 and shows synergistic effect; ctc.ltoreq.80 shows antagonism; 80< ctc <120 appears as additive.
And LC of the composition 50 LC with a value less than one or two single doses 50 The value means that the composition is used in a dose less than one or both of the single doses when the same effect (50% mortality) is achieved.
The test results are shown in Table 2.
Table 2: indoor combined toxicity test result of compound I-isoxazole insect amide on tetranychus cinnabarinus
From the data, the compound I, isoxazole and tebufenozide compound 5 pairs tetranychus cinnabarinus LC 50 The value is 0.038mg/L, and single dose LC 50 Values of 0.50mg/L and 0.039mg/L, respectively, then mean that the dosage of the composition (0.038 mg/L) is less than the dosage of one or both of the single doses (0.50 mg/L and 0.039 mg/L) when the same effect is achieved (mortality 50%); in addition, from the definition of the co-toxicity coefficient, the control effect of the composition is higher than the theoretical effect of two single agents to different degrees; due to field usage dose and indoor LC 50 The values are positively correlated, so that the field dosage of the composition can be correspondingly reduced, thereby reducing the use cost and reducing the environmental pollution.
