Full Title

Full titles differ between systems:

IPC:

Biocides, pest repellants or attractants, or plant growth regulators containing organic compounds containing a carbon atom having three bonds to hetero atoms with at the most two bonds to halogen, e.g. carboxylic acids > containing the group —CO—N, e.g. carboxylic acid amides or imides; Thio-analogues thereof > the nitrogen atom being directly attached to an aromatic ring system, e.g. anilides

CPC:

Biocides, pest repellants or attractants, or plant growth regulators containing organic compounds containing a carbon atom having three bonds to hetero atoms with at the most two bonds to halogen, e.g. carboxylic acids (containing cyclopropane carboxylic acids or derivatives thereof, e.g. cyclopropane carboxylic acid nitriles, A01N53/00) > containing the group —CO—N<, e.g. carboxylic acid amides or imides; Thio analogues thereof > the nitrogen atom being directly attached to an aromatic ring system, e.g. anilides

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
