AI Technical Summary

Benefits of technology

The compound described in this patent has strong insecticidal and acaricidal properties, effectively controlling a variety of pests and parasites. It is particularly useful for pests that develop resistance to existing insecticides. Additionally, the compound has low adverse effects on mammals, fish, and beneficial insects, and has a low impact on the environment. Therefore, this patent provides a novel and useful pesticide.

Problems solved by technology

Recently, pests acquire resistance by the use of pesticides such as insecticides or fungicides over long term, and thus control by the insecticides or fungicides that have been conventionally used becomes difficult.

In addition, a part of known pesticides has a high toxicity, or some of them start to disturb native ecosystems due to long-term persistency.
