Applications: Piperonyl butoxide (PBO) is one of the most outstanding synergists to increase pesticide effectiveness. Not only it can obviously increase pesticide’s effect more than ten times, but also it can extend its effect period. PBO is widely used in agriculture, family health and storage protection. It is the only authorized super-effect insecticide used in food hygiene (food production) by the UN Hygiene Organization.
