摘要

Provided is a co-crystal which is composed of a diamide-based insecticidal activity component and a neonicotinoid-based insecticidal activity component, and which exhibits an excellent insecticidal effect for a long period of time, while suppressing the occurrence of chemical damage on useful plants. This co-crystal is obtained by a method which comprises heating and stirring of a suspension that is obtained by suspending a diamide-based insecticidal activity component and a neonicotinoid-based insecticidal activity component in a solvent such as water.
