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

Packing and storage:

Packed in 200kg iron drums with PVF inside.

PBO should be stored in ventilative and dry (low temperature) storehouse, Do not make PBO moist or shined during storage and transportation,
