Description

Technical field

[0001] The invention belongs to the field of pesticides, and relates to a novel spirodiclofen compound and a synthesis method thereof, which are suitable for insecticide and acaricide. Background technique

[0002] Spirodicin (structure III) is a highly effective quaternary keto acid acaricide developed by Bayer. It has a different mechanism of action from existing insecticides and acaricides. By inhibiting the synthesis of lipids in the body of harmful mites, it is effective against nymphs. Especially it has an excellent inhibitory effect on mite eggs.

[0003] CN101255147A reported the structural formula The compound of chrysanthemum oxychloride was reacted to synthesize a series of spirodiclofen derivatives, and the biological activity of mites and broad bean aphid was tested.

[0004]

[0005] Due to the large and frequent use of drugs, harmful insects and mites have developed severe resistance to many insecticides and acaricides. The development of insecticide...
