HARDI is world leading in the understanding of the concept of spray accountability and it is this knowledge that underpins its leadership in today's spraying.

Fundamental research with nozzles by HARDI agro-scientists is conducted in their own dedicated laboratories and those of independent Research Centres at many key institutions throughout the world. Sites where field research is conducted are very diverse - ranging from the temperate conditions of Northern Europe to the tropical crops of Australia.

Instrumentation used in HARDI’s laboratories is at the leading edge in drop size analysis studies.
It is this broad - but intensive approach - which, when combined with state-of-the-art manufacturing techniques and computerised quality control programmes, guarantees that HARDI nozzles will meet the demands of better crop protection.
