In Germany it is done in rare cases to fight one specific insect (Eichenprozessionsspinner) in forests only and exclusively using helicopters because they can deliver the pesticide in small doses exactly where it is needed. Helicopters are also used for neutralizing acid soils with calcium compounds (Waldkalkung).
Aerial spraying of pesticides was common practice in the former German Democratic Republic (like in most ex eastern block countries) but not any more since the reunification nearly 35 years ago.
