Rubus Staphyt Trials

Staphyt carried out formal trials as part of a project funded through Hort Innovation, the project looked to develop chemical residue datasets to support the registration of new agrichemical options for producers. These datasets are essential for getting APVMA approval for new chemicals to be used within the sector and have to be developed for each crop species.
