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 BioControl Agent Avengelus 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
When Avengelus 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 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.
The application of tree wax, wound balm etc. is considered critical. Most products promote the infestation of diseases, as wound closures often crack and pathogens penetrate through the new cracks and find warm, humid millieus under the seal – ideal growth conditions. With Avengelus this risk is not given.
Contains fungal spores (Trichoderma) 1×108 (CFU per ml).
Application & Dosage:
When applying to wounds, no measurements are required, the undiluted gel mass should be applied over the entire surface with a brush or spatula. A dilution of the gel with water and spraying is also a possible treatment option.
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. The temperatures should also be below 30 °C.
Trichoderma 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 populations, especially on the sapwood, can be found after months (depending on environmental conditions).
Please note: Avoid mixing Avengelus with products that have a pH value below 4.5 and above 8. Do not mix with products containing fungicides.
Avengelus should be protected from direct sunlight and temperatures above 30 °C. Do not store below 0 °C. Shelf life of 18 months if stored between 0-4 °C. Shelf life of 12 months when stored between 10-15 °C. Shelf life of 6 months when stored between 20-25 °C. Empty packages can be disposed of with the household waste.
