Trials with tree injections using the systemical in secticide Confidor WG 70 in the concentration 80mg a.i./ml solution on horse chestnut trees to control Cameraria ohridella showed good results. The insecticide formulation was applied not before 24 July when the first generation of the insect had nearly finished its development inside the leafmines. Therefore only the second and third generation could be controlled. 11 weeks after application the injected trees (3ml per 20cm round) showed only about 50% defoliation whereas the nontreated trees had more than 80% fallen leaves.
