If you have already done safe use and boom sprayer, you may want to add handheld( knapsack) , in which case it is just 1 day training and then practical assessment the following week.
Or done handheld and now want boom? Same applies.
We are running a pesticides session 10- 12 Jan , but we have a small number of places available , on 11th for boom, and the 12th for handheld.
