The Minor Use Foundation organized the Advanced Concepts of Manual 224 FAO Training Workshop held November 15-19, 2021, to further the Foundation’s vision to break down agricultural trade barriers resulting from global misalignment of residue tolerances on minor crops. Attendees of the virtual event included government officials, regulators, academia, consultants, researchers and growers from 21 Latin American and Caribbean countries. The workshop was taught by Dr. Eloisa Caldas, professor at the University of Brasilia and a member of the FAO Expert Panel on Pesticide Residues.

The workshop content was divided in to five sessions including:
- Environmental Fate of Pesticides in Soil, Water and Water-Sediment Systems;
- Sampling, Sample Preparation and Analysis, Efficiency of Extraction, Stability of Residues;
- Selection of Supervised Trials for Estimation of STMRs (Supervised trials median residue), HRs (highest residue) and MRLs (maximus residue limits) Including Application of Statistical Methods;
- Evaluation of Supervised Trial Data. Estimation of Maximum Residue Levels and STMR and HR values; and
- Estimation of Dietary Intake.
The training, available on the Foundation website, was a great opportunity to get acquainted with people working in the same topics in the region that could collaborate in the near future on common interests. The event also provided an opportunity to gather information about important topics for future training workshops.
Attendance and engagement throughout the event was very high. Between 70 and 100 people attended each of the five days showing very elevated levels of understanding and engagement by posing questions that were solved during the sessions.

With the success of the workshop and positive feedback from participants, the Foundation hopes to organize and hold future trainings and meetings to further support agriculture in the region.
