"Electrodyne" bench.Forestry Commission,Corris,Wales. Used for applying an electrostatically charged spray of persistent insecticide to forestry plants prior to planting.The conveyor is earthed and thus ensures that the spray only attaches to the plants. Efforts to minimise chemical use as well as the withdrawl of many insecticides have encouraged research into other methods of control of Hylobius and Hylastes. Field scale use of nematodes and stump removal have given promising results.
