A01N

PRESERVATION OF BODIES OF HUMANS OR ANIMALS OR PLANTS OR PARTS THEREOF (preservation of food or foodstuff A23); BIOCIDES, e.g. AS DISINFECTANTS, AS PESTICIDES OR AS HERBICIDES (preparations for medical, dental or toiletry purposes which kill or prevent the growth or proliferation of unwanted organisms A61K); PEST REPELLANTS OR ATTRACTANTS; PLANT GROWTH REGULATORS

Introduced: September 1968

Description

A01N encompasses compositions and methods for preserving biological materials and controlling organisms through chemical means. It covers biocidal agents used as disinfectants, pesticides, and herbicides, as well as pest repellants, attractants, and plant growth regulators. This classification includes active ingredients, formulations, application techniques, and efficacy data for agricultural, veterinary, and sanitary uses. The scope spans synthetic and natural biocides, their chemical structures, and mechanisms of action across diverse pest and pathogen targets.
