[0030] Example: Joint toxicity test of different ratios of sulfoxaflor and AgroSpred Prime on celery aphids.
[0031] In the test, celery aphids were used as the test object, and the method of measuring the toxicity of leaf-soaking inoculated insects was adopted. The specific method is as follows:
[0032] 1. Prepare the pesticide raw material with organic solvent DMF or DMSO to make a 1%-5% mother solution, and then dilute the pesticide mother solution with an aqueous solution containing 0.1%-Tween to form 5-7 serial determination solutions;
[0033] 2. Dip the celery leaves with celery aphids directly into the liquid to be tested for 5 seconds, then take them out and put them in a clean petri dish, dry and seal; repeat 3 times for each liquid. Check the mortality after keeping in the light incubator at (27±1)°C for 24-72 hours (depending on the nature of the insecticide);
[0034] 3. Criterion for judging death: lightly touch the worm body with a needle and no response or u...

[0048] Embodiment 2: Field control effect of compound pesticide preparation of the present invention on celery aphid
[0049] The experiment was carried out at the vegetable base in Daxing District, Beijing. Select a celery planting site with good water and fertilizer conditions and serious occurrence of celery aphids. Spray with water according to the design concentration of each treatment, every 667m 2 Use 30kg of water to evenly spray the front and back sides of the celery blades with a Gongnong-16 sprayer. Each treatment was repeated 4 times, and the area of each plot was 50 square meters, arranged in random blocks. Investigate the insect population base before spraying, adopt the 5-point sampling method, select about 5 celery plants with celery aphids at each point, and select 10 celery leaves with a suitable amount of insects per plant (depending on the insect population density) to count the celery on the plant The number of aphids is used as the base number of ins...
Embodiment 3
[0055] Embodiment 3: Field control effect of compound pesticide preparation of the present invention on cotton aphid
[0056] The test was carried out at the experimental base in Langfang City, Hebei Province. Select cotton fields with good water and fertilizer conditions and heavy occurrence of cotton aphids. Spray with water according to the dosage of each agent, every 667m 2 Use 30kg of water and spray evenly with Gongnong-16 sprayer. Each treatment was repeated 4 times, and the area of each plot was 50 square meters, arranged in random blocks. Investigate the base number of insect populations before spraying, adopt the 5-point sampling method, select about 3-5 cotton leaves with cotton aphids at each point (depending on the density of insect populations), and count the number of cotton aphid larvae on a certain plant, and use this as a pesticide application method. The former population base. The surviving cotton aphids on the fixed plants were investigated 1, 3 and ...
