Abstract
The invention provides a m-diamide compound, and a preparation method and application of the compound. The m-diamide compound has a structure shown as formula I. The m-diamide compound can have high insecticidal activity at a low dose, takes effect quickly, can exert the insecticidal activity a day after application and achieve the very high insecticidal activity within 3 days, and has good quickaction performance; in addition, since the compound has a good effect at the low dose, harms to plants and human due to excessive concentration are reduced; the residue is low during application; theenvironmental protection is better facilitated; and the preparation method of the compound is simple, efficient, easy in large-scale production and wide in application prospect.
Description
technical field [0001] The invention belongs to the field of insecticides, and relates to a meta-diamide compound and a preparation method and application thereof. Background technique [0002] In the production of crops such as agriculture and horticulture, the damage caused by pests is still very significant. Due to the resistance of pests to existing pesticides and the unfriendly environment of existing pesticides, it is always necessary to develop better activity and lower dosage. , New insecticides that are more environmentally friendly. [0003] The insecticidal activity of intermediate diamide compounds has been reported, such as CN102119143A discloses compound KC1 (i.e. compound 7-1574 in CN102119143A), KC2 (i.e. compound 7-1595 in CN102119143A) and KC3 (i.e. compound 6-5907 in CN102119143A) And its insecticidal activity, among which KC2 has been commercialized, and its English common name is broflanilide. These disclosed compounds have insecticidal activity, howev...
