Fewer seedlings treated with pesticides 2019
The usage of pesticides on coniferous seedlings declined by 4 per cent 2019 compared to 2018. Instead mechanical treatment is used. This is shown by annual statistics from the Swedish Forest Agency on sold seedlings. The amount sold is about the same as the previous year.
In 2019 381 million seedlings of forest species were delivered, which is the same level as in 2018. The number of delivered seedlings of Scots pine has evened out. However, it is too early to say whether it is a new trend or not. Seedlings of Norway spruce and Scots pine together constitute 96 per cent of total number of delivered seedlings. The trend of declining numbers of delivered lodgepole pine seedlings continues, but at a slower rate, and make up for 1,7 per cent. The number of broadleaf seedlings is stable and make up for only 0.6 per cent.
Container-rooted seedlings is the dominating method of production for coniferous species. Scots pine and lodgepole pine are basically only produced as container-rooted seedlings. 2019 the share of Norway spruce seedlings produced as container-rooted was 77 per cent, which is an increase by 9 per cent compared to 2018. Most other coniferous species and broadleaves are produced as bare-rooted seedlings. Only a very small share of coniferous seedlings was produced as transplanted container-rooted seedlings.
Seed propagation was the totally dominating method of propagation of coniferous seedlings 2019. The share of vegetatively propagated coniferous seedlings was negligible.
54 per cent of coniferous seedlings were delivered with some sort of protection against insect pests 2019, and 46 per cent were delivered untreated. The share of seedlings with some sort of mechanical treatment shows an increasing trend and was 42 per cent 2019. Correspondingly chemical treatment shows a clearly declining trend and was down to 12 per cent.
80 per cent of delivered seedlings in 2019 originate from Swedish seed-orchards, which is an increase compared to 2018. Seedlings of Scots pine almost solely (99 per cent) originate from Swedish seed-orchards. The share of Norway spruce seedlings originating from Swedish seed-orchards increased to 67 per cent 2019.
During 2018 nearly 48 million seedlings were imported to Sweden from other countries. That means 12 per cent of delivered seedlings 2018 (out of 384 million seedlings in total) had at least partly been produced outside Sweden. The import of seeds from abroad to Sweden was nearly 800 kg, out of which seeds of Norway spruce made up for 730 kg, which is rather little in comparison to previous years beginning with 2004.
Statistics refer to seedlings for use in Sweden.
The survey is part of Official Statistics of Sweden.
Container-rooted seedlings – the roots are surrounded by a substrate cluster that usually consists of peat.
Transplanted container-rooted seedlings – container-rooted seedlings which are transplanted as bare-rooted seedlings.
Bare-rooted seedlings – seedlings without accompanying cultivation substrate (soil or peat) around the roots.
