Summary The potential secondary effects of insecticides used in forests on man and animals, on injurious insects and its enemies and on the biocenosis are described. Considerations, experiences and investigations allow the conclusion, that an application of an insecticide once during the existence period of a forest stand or in long intervals does not deteriorate the ecosystem. The necessity of the measure, kind and dosage of the insecticide and the way, time and area of application have to be payed attention to. Experiences on the secondary effects of frequently repeated chemical control measures are missing. Therefore extreme care, if necessary, the carrying out of investigations and the testing of suitable biological methods must be demanded.
