発されてきた殺虫剤に比べ高価なことである。 In recent years, against this background, synthetic pyrethroid insecticides have been attracting attention because of their excellent insecticidal power, their outstanding effectiveness against pests resistant to organic phosphorus or carbamate agents, and their relatively low toxicity to humans and livestock. I came flying. However, the disadvantage of this synthetic pyrethroid insecticide is that it is highly toxic to fish, which limits its range of use. Furthermore, they are more expensive than conventionally developed insecticides.
