Have you always wanted to know the difference between a risk and a hazard? Between the technical material and the technical concentrate of a pesticide?
On special request of Toolkit users the Toolkit now hosts a greatly expanded section on Terms and Definitions which contains about 160 terms that are frequently used in the field of pesticide registration.
All definitions in the list are taken from reputable and authoritive sources -like FAO/WHO, GHS, IPPC, IPCS and IUPAC- and combined into a single glossary.
The terms can be found using the general search function on the website or through the "Terms and definitions" menu item which provides access through an alphabetized index.
