Pádraic Walsh found me with his Deaddock prototype at a time when docks in silage were causing a lot of dietary issues in my dairy herd. When he arrived on the farm with the machine at early development stage, "Seeing was NOT believing!" However I liked the idea and had a lot of docks that needed killing. I had used broadcast spraying over the years with mixed results. To get a good kill takes a lot of expensive product which is sever on the grass, kills clover and not very friendly to the environment. On some high clover swards the "clover friendly sprays were not very effective on the docks. We used the Deaddock as much as possible during the growing season of 2017. The machine was at an early stage of development and had some difficulty with certain light conditions esp low evening sunshine. Padraic has solutions for in the pipeline for this issue. We used the Deaddock in many different conditions to expose any shortcomings and aid development. We had varying results which served to show me just how important this machine will be the environmentally friendly and effective dock control. In many of the pastures done the kill rate was very high with clover untouched and with no set-back to pasture growth. Another important benefit of spot spraying is that the Deaddock machine only used a fraction of product needed for broadcast spraying. Also while very effective on heavy Dock infestations, it is an economical way of dealing with smaller numbers of docks that would not justify broadcast spraying and never letting heavy infestations of docks re-establish.
