Abstract

Insecticides will be removed from Swedish forestry, at present insecticides are used to treat our seedlings to avoid them from being attacked by pine weevils. With the forthcoming ban on insecticides alternative protective measures will have to be tested.
Holmen Forest Ltd has aimed to find an alternative and have developed a mechanic pine weevils protection accessory as well as a new concept on planting pipes. Studies have been conducted on the behalf of Holmen Forest Ltd to see how planting with the newly developed mechanical protectors and plant pipe stands up against the conventional methods used today. The study was conducted over a three week period.
Three factors were compared regarding planting quality including i) pressure around the plant, ii) the depth the plant ended up in, iii) plant angle. Mechanical plant pipes were used in the study, and where tested like a one-handed and a two-handed pipe.
The study concludes that further development is needed for the mechanic plant protector to live up to the speed and quality of conventional methods. If such a development succeeds it will be a lucrative product to replace insecticides. The aim is to keep using conventional methods in forestry for now and continue with the development of alternative measures.
