Example 1: indoor toxicity determination of compound medicament on diamondback moth
The tested pests: selecting healthy 3-instar larvae with consistent sizes as test insects for cabbage diamondback moths;
reagent to be tested: a technical material of flubendiamide and a technical material of cyfluthrin; market purchase;
the test method comprises the following steps: the leaf soaking method is adopted. On the basis of a pre-test, each medicament is provided with 7 concentration gradients, clear water is used as a blank control, the steps are repeated for 4 times, and 24 plutella xylostella 3-instar larvae are reused each time. Beating clean cabbage leaves into round pieces with the diameter of about 2cm by using a puncher, immersing the leaves into corresponding medicament treatment concentration, taking out after 10s, naturally drying the leaves, placing the leaves into 12-hole plates, placing 1 piece of the leaves into each hole, and inserting 2 test insects starving for 4h, and covering 1 layer of paper on the 12-hole plates (preventing the test insects from escaping). The test is carried out in a pest breeding room, and 48 test pest death conditions are observed. The dead was determined to be dead by gently touching the insect with the brush pen. The virulence regression equation, LC50, was calculated using the DPS software as a statistical tool.
The co-toxicity coefficient of each mixed preparation is calculated by adopting a Sun Yunpei co-toxicity coefficient method. The co-toxicity coefficient is used for representing the combined action of the compound agents, the co-toxicity coefficient is more than 120 for representing that the compound agent has obvious synergistic action, the co-toxicity coefficient is less than 80 for representing that the compound agent has antagonistic action, and the co-toxicity coefficient is between 80 and 120 for representing the addition action.
And (3) testing results: as can be seen from Table 1, the stomach toxicity activity LC50 values of the crude drug of the brotrochan difluoride and the crude drug of the cyfluthrin to the plutella xylostella are 0.055mg/L and 26.590mg/L respectively, namely the crude drug of the brotrochan difluoride has higher stomach toxicity activity to the plutella xylostella compared with the crude drug of the cyfluthrin. After the technical product of the flubendiamide and the technical product of the cyfluthrin are compounded, the synergistic and additive combined effect is shown on the plutella xylostella; when the mass ratio of the brotrochar diflufenican to the cyfluthrin is 20:1-5:1, the compound medicament has additive effect on diamondback moths; when the mass ratio of the brotrochar diflufenican to the cyfluthrin is 1:1-1:20, the compound medicament has synergistic effect on diamondback moths. Particularly, when the mass ratio of the brobendiamide to the cyfluthrin is 1:10, the CTC value is 170.3, and the synergistic effect is remarkable.
