Problems solved by technology

[0006] Long-term use of a single insecticide will easily lead to insect resistance and increase the amount of pesticide used, leading to adverse consequences such as high toxicity, large dosage, large residues, and poor efficacy, and the field of action is relatively single
However, the research and development of pesticide compounds requires a long research and development cycle, and the work of screening compound structures is very complicated, which cannot be undertaken by ordinary research and development institutions.

[0066] (1) Drugs to be tested

[0067] The original drug of o-phenylenediamine insecticide A was provided by Syngenta, and the original drug of abamectin was provided by Qingdao Kaiyuanxiang Chemical Co., Ltd.

[0068] (2) Source of tested insects

[0069] Plutella xylostella larvae raised for generations indoors, indoor conditions: temperature (26 ± 2) o C, relative humidity 68%±5%, photoperiod 16 / 8h (L / D).

[0070] (3) Single-dose determination method

[0071] The two groups of original drugs were dissolved in a small amount of acetone by worm soaking method, and then diluted with 0.1% Tween aqueous solution to form 5 concentrated solutions with equal difference, which were diluted in beakers for later use, and clear water was used as a control.

[0072] Plutella xylostella larvae of the same size were immersed in the medicinal solution of the insect cage for 5 seconds, and after absorbing the excess medicinal solution, they were placed in a petri dish with a diameter of 9 ...

Abstract

The invention relates to an insecticidal combination containing o-phenylenediamine insecticide and abamectin. Active components of the insecticidal combination are o-phenylenediamine insecticide A and abamectin, and the remaining are auxiliary components for preparing pesticide formulations. The weight part ratio of the active component o-phenylenediamine insecticide A to abamectin is (1-35):(5-0.1), the total weight parts of the active components account for 1-30% the total weight parts of the formulations. The pesticide formulations capable of being prepared from the insecticidal combination comprise wettable powder, suspending agent, soluble liquid, emulsion in water and water dispersible granules. The combination can be prepared into the formulations suitable for agricultural application, the insecticidal combination has an obvious synergistic effect, the insecticidal spectrum is expanded, the pesticide amount is reduced, the control effect is improved, residue is less, the duration is long, and the insecticidal combination is favorable for delaying pesticide resistance of pests and environmental protection.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing o-phenylenediamine insecticides and abamectin. Background technique [0002] The chemical structural formula of o-phenylenediamine insecticide A is as follows: [0003] , [0004] The insecticide is a new insecticide compound announced by Syngenta, and its mechanism of action is currently disclosed as a ryanodine receptor agent. There are no more experimental reports or publications, and there is no disclosure of field tests in the field of compounding. [0005] Abamectin, the English common name abamectin, is a macrolide disaccharide compound, and is a biopesticide isolated from soil microorganisms. It has contact and stomach poisoning effects and weak fumigation effect, no systemic effect, strong penetration effect on plant leaves, can kill subepidermal pests, and has a long lasting effect. Its mechanism of action is dif...
