This paste has a preventive effect and spreads a
odor barrier making the tree unattractive
for the spider mite beetle. It can be easily applied
by smearing the trunk and first part of the crown
with the pasta. This treatment should be in the course of the
summer season be repeated to keep the odor barrier intact
keep for optimal results.
A large number of bark beetles, weevils longhorn beetles and
Wood wasps live in weak and dead trees and shrubs.
The main group for infestation immediately after planting
is the group of bark beetles and particularly subgroup of spider beetles.
The mother beetle drills small holes in the trunk (especially on
the warm southwest side), mates, makes a passage and lays
eggs. The larvae eat corridors through the cambium and the
young wood tissue. The tree loses at the feeding sites
the entire sap flow. A planted tree comes
in spring in leaves and after infestation begins
turning to yellow and shrinking, very similar to
desiccation symptoms. The beetle is common
throughout Europe and is especially active in heat.
Some examples include elm sapwood weevil (Scolytus scolytus),
birch spider beetle (Scolytus ratzeburgi), pine shaver
(Tomicus piniperda) and oak spider beetle (Scolytus intricatus).
Regularly affected host plants are Quercus, Castanea,
Ulmus, Fagus and Populus and, to a lesser extent, Carpinus,
Corylus, Ostrya, Sorbus and Betula. In particular, the oak spider beetle
is a threat to the newly planted.
The dosage for using ESK is 1 kg per 8 m2
bark surface. The dosage is highly dependent on whether the
bark is rough or smooth. Repeat treatment 2-3x after 1-1.5
month administration, especially in stressful conditions
(dry warm periods).
