Due the Coronavirus outbreak the Ctgb has received cancellations and we expect to receive more cancellations. Therefore the Ctgb has decided to cancel the workshop Tips and tricks to improve your dossier for protected uses.

Ctgb is planning to organise the meeting in October 2020.

The focus of the workshop will be on the assessment of plant protection products for applications on protected crops. The workshop will be held in English.

The fee for this workshop is € 820,- per participant. If you would like to participate, please fill out the registration form below and return it by  March 2, 2020.

If you are available on both dates, please tick both date boxes, which enables us to come to an equal distribution of participants over both days. You will be informed asap to which day you are assigned (both days have the same programme).

The workshop starts at 09.45 h (registration opens at 09.15 h). For each topic, there will be adequate time allotted for discussion. The afternoon will end with networking drinks.

Please note that attendance is limited to a maximum of 25 participants per workshop. Cancellation after March 23, 2020 will not be reimbursed.
If the number of participants is not sufficient to fill up both workshops, only one workshop will take place.
