Wounds as a way of entry for pathogens
Any wound on a tree, whether it be due to pruning, building sites, storm damage etc., represents a potential way of entry for pathoges, especially wood decay fungi. The arborist can wait for the right time of the year to prune by considering increased periods of fungal sporulation associated with wood decay fungi, such as during autumn in the northern hemisphere. However, the easy-to-apply Avengelus BASIC gel can be used as a preventative treatment after pruning, which would mitigate the damaging effects of harmful fungal spores during virulent periods.
Isolation of wounds
The treatment of wounds is of particular importance for the long term preservation of trees. When wounds occur, the tree tries to isolate itself against bacteria and fungi, etc., through compartentalisation and zone line formation. This active defence in trees includes the production of secondary metabolites which act as an antibiotic, e.g. phenolic compounds. The synthesis of these defence compounds is in part triggered by salicylic and jasmonic acid. Trichoderma harzianum significantly increases the amount of salicylic acid already formed at the infected area.
When Avengelus BASIC is applied to fresh pruning wounds, it acts as a ‚protector‘ by parasitising incoming spores from decay-causing fungi. The application of the product can also indirectly lead to faster wound closure, as a result. The patented gel formulation of Avengelus BASIC makes it easy to apply to wounds. It forms a protective film on the surface and prevents infection from potential pathogens. The gel helps to minimise the effects of pathogens, allowing the tree to grow and develop rather than tend to fungal infections during wound closure. Depending on the size of the wound, repeated application of the gel is recommended over time.
Avengelus BASIC and its active ingredient, Trichoderma harzianum, is most suitable for tree wounds, as it can be applied with a brush around the wound and even inside cracks, which develop after a period of desiccation. This further minimises the risk from disease entry.
Contains fungal spores (Trichoderma harzianum CBS 140589) 1×108 (CFU per ml)
When applying to wounds, no measurements are required, the undiluted gel mass should be applied over the entire surface with a brush or spatula.
For brushing with gel or spraying a spore suspension, we recommend that you carry out the treatment during rain free periods, otherwise the spores will be washed off the surface. Trichoderma harzianum also survives on the ground‘s surface, depending on moisture and nutrient availability, and rapid reproductive cycles. For gel application to a wound surface, Trichoderma harzianum populations, especially on the sapwood, can be found after months (depending on environmental conditions).
Please note: Avoid mixing Avengelus BASIC Gel with products that have a pH value below 4.5 and above 8. Do not mix with products containing bactericides, fungicides or phosphates.
Avengelus BASIC Gel should be stored in a cool and dry place and protected from direct sunlight. Ideally at a temperature of 10-15 °C. Once opened, bottle should be stored at 4-8 °C.
