Dormant oil
Not sure where dormant oil fits. Is it a Barrier, a Repellent, a Poison or a Microbial? Does anyone know what is the purpose of applying dormant oil? I have seen different descriptions of dormant oil: Thanks in advance, Ottawahitech (discuss • contribs) 15:10, 29 March 2024 (UTC)
 * dormant oil that smothers overwintering insects and their eggs
 * Dormant oil that is used as a fungicide or bactericide
 * Dormant oil that is sprayed on the trunk to prevent scale laying insects from climbing up to lay their eggs
