AI Technical Summary

Technical Problem

Existing arylpyrrole pesticides are harmless to plants but highly toxic to fish, bees, etc., and have limited biological activity, making it difficult to be widely used in agricultural production.

Method used

A series of arylpyrrole N-ester derivatives were designed and synthesized. By introducing ester structural fragments, the systemic activity of pesticides was significantly improved while maintaining excellent biological activity. They are especially effective against various pests and mites. effect.

Benefits of technology

The new arylpyrrole N-ester derivative has excellent biological activity against a variety of pests, pest mites and nematodes at low concentrations, which is significantly higher than the commercial pesticide bromiprene, and is safer for cruciferous plants. Suitable for broad-spectrum insecticide, acaricide, nematode killing and bactericidal.
