ARDENTO: treatment for Bleeding canker at Horse Chestnut trees, Alnus sp., Acer sp., Quercus sp. and Fagus sp.
Biological Crop Care for trees and shrubs, suffering from Bleeding Canker.
ARDENTO is a highly concentrated liquid composition of specific herbal concentrate, based on water. Applicable using soil injection in combination with airing or hosing. Characteristics are the high amounts of natural auxines, cytokinines and various trace elements. ARDENTO is SKALcertified.
ARDENTO is absorbed by the roots of the tree and by the soil. Due to the compilation of ARDENTO the roots, leaves and soil will increase their resistance, favored by the root stimulating and nutritional ingredients.
The tree will develop his own defense system by increasing the resistance.
The ingredients in the product have, in addition to a soil improvement and a crop enhancing effect, an indirect effect on pests and diseases that can cause the bleeding disorder in certain trees like Horse Chestnut (Aesculus hippocastanum), such as the leaf miner (Cameraria ohridella) and the bacteria Pseudomonas syringae.
Insects are inhibited in their development. The treated soil and trees are no longer attractive to them. And thus the damaging larvae will no longer eat parts of the leaves. The treated trees will show a healthy growth. Pathogens will have fewer grips on the renewed tree.
ARDENTO can be used as an indirect expulsion against all kinds of nuisances of insects, larvae, fungi and other appearances in the soil and the crown at all the various tree species where the bleeding disease may occur. In particular, the Chestnut but also in the Alder, Beech and Oak
Especially when in the past there has been much inconvenience and damage, the product can be best applied as a preventative. But when damage and deterioration is detected, the product can still be, on targeted advice, successful.
For optimal operation moist conditions are required. Otherwise, watering is a necessity.
The liquid product can be applied by watering or by soil injection.
First time apply if the tree becomes active again in spring. First year, the cure must be repeated in June and August. Repetition can be necessary depending on disease pressure.
- Dissolve 1 liter concentrated ARDENTO in 50 liters water
* Preventative: use 1 liter concentrated ARDENTO on 250 m2 root surface.
* Curative: use 1 liter concentrated ARDENTO on 100 m2 root surface.
- Soil injection:
- Dissolve 1 liter concentrated ARDENTO in 50 liters water.
Injection: use 5 liters solution for each hole.
Number of holes depends on the diameter of the trunk.
Number of holes in crown projection:

The treatment lasts for two years.
1. The first treatment takes place around April, simultaneously with the “waking up” of the tree.
2. The second treatment takes place around June/July before the population of the leaf miners (chestnut moths) and other insects develops.
3. The third treatment takes place around August/September to create a vital and toughened tree for the winter period.
The following year this treatment will be repeated.
Approach of treating the bleeding canker of trees:
There are several reasons which have a strongly influence on the vitality of a tree.
A weakened tree will be more susceptible to various fungi and bacteria, especially at the roots.
We therefore recommend to apply ARDENTO through a soil injection at the roots combined with the special liquid fertilizer OMNIFERTIL.
Before treatment starts, it is necessary to investigate the condition of the soil and to inventory the depth of the roots in the soil. The working depth is determined depending on soil type, soil structure and humus content.
We differentiate the various circumstances and conditions of the growing location:
On a depth of about 60 cm vertical airing holes will be created by air pressure and special equipment.
- Soil type (density)
This creates a large number of horizontal ducts, allowing the entire rooted space to be achieved.
Simultaneously ARDENTO and OMNIFERTIL are inserted under air pressure to the whole root area.
Since 2003 the development of treated trees is monitored with all comments precisely charted.
The results do speak for themselves and prove that with this approach we are on the right track.
