Embodiment Construction

[0023] Combined toxicity of different ratios of spirotetramat and amides insecticides

[0024] 1.1 Drugs to be tested

[0025] 95% spirotetramat and 95.3% chlorantraniliprole were provided by the R&D center of Qingdao Hailier Pharmaceutical Co., Ltd.

[0026] 1.2 Source of tested insects

[0027] The third-generation adults of cabbage aphids were raised continuously for 10 generations with potted cabbage seedlings indoors, and the temperature was ( 25 ± 2 ) o C, relative humidity 50%±4%, photoperiod 14 / 10 h (L / D).

[0028] 1.3 Single dose determination method

[0029] The two original drugs were dissolved with a small amount of acetone by the worm soaking method, and then diluted with 0.1% Tween aqueous solution to form solutions of 5 equal concentrations, which were diluted in beakers for later use, and clear water was used as a control. The third-generation cabbage aphid adults of the same size were soaked in the liquid medicine of the insect cage for 5 seconds, and ...

Abstract

The invention relates to a pesticide insecticidal composition, the effective components of which contain (A) spirotetramat and (B), i.e. one of amide insecticides. Specifically, A and B are in a mass percentage of 1-80:80-1, and the content of A and B in the compound preparation is 1-80%. The compound pesticide composition prepared by the invention can be prepared into missible oil, suspending agents, wettable powder, water dispersible granules, emulsions in water and other dosage forms by methods well known to technicians in the field. The insecticidal composition provided by the invention is suitable for controlling piercing-sucking mouthpart pests in vegetables and fruits, and is especially suitable for controlling aphids, whiteflies, mealybugs, scale insects, plant hoppers, thrips, Empoasca pirisuga Matumura, as well as lepidoptera, coleoptera pests like diamondback moths, cotton bollworms and the like.

Description

technical field [0001] The invention relates to a synergistic pesticide and insecticide composition, the active ingredients of which are spirotetramat and one or more selected from amide insecticides. Background technique [0002] Piercing-sucking mouthparts pests such as aphids, planthoppers, thrips, and scale insects have the characteristics of short reproduction cycle, large reproduction number, and obvious generation overlap, and are prone to develop drug resistance. Due to the large-scale use in successive years, the above-mentioned pests have developed serious resistance to pesticides such as imidacloprid and acetamiprid. [0003] Spirotetramat, the English name of which is Spirotetramat, is a tetronic acid insecticide developed by Bayer Company, and belongs to the same class of compounds as the insecticide and acaricide spirotetramat and spirobetramat. Spirotetramat has unique action characteristics and has excellent two-way systemic conduction performance. It can mo...
