In a collaborative effort between Chaucer Landscape Management and Sorbus International, a new study is underway to assess the efficacy of Avengelus Trichoderma atrobrunneum-based soil inoculation granules and bark gel in combatting the progression of honey fungus (Armillaria spp.) in tree stems and soil areas.
Honey fungus, a notorious pathogen known for its devastating impact on various tree species, has long posed a significant challenge to arborists and environmentalists worldwide. The introduction of Avengelus Trichoderma-based solutions offers a glimmer of hope in the ongoing battle against this destructive fungus.
The study, conducted initially over an 18-month period, aims to meticulously document the effectiveness of two treatment modalities. Lead researcher, Neil Moulton (BSc (Hons), MArborA, DipArbL4) of Chaucer Landscape Management will monitor the progress of treated trees at six-month intervals, providing valuable insights into the long-term impact of the interventions.
Treatment methodologies
Avengelus Bark Gel (tree balm) is applied topically to targeted areas, specifically rhizomorphs and lifted cambium beneath affected bark. Administered monthly between April and September, this method targets the localised areas of infection with precision.
Avengelus Granules: Trichoderma soil inoculation granules are spread at a rate of 5 g per square metre and watered in thoroughly. Similar to the bark gel, this treatment regimen is implemented monthly between April and September, ensuring consistent application and sustained efficacy.
Bridging theory and practice
The study intends to provide an ‘in practice’ link between previous peer-reviewed laboratory studies and the efficacy of Avengelus. By evaluating the performance of these Trichoderma-based treatments under real-world conditions here in the UK, researchers aim to validate their potential as practical solutions for arboricultural challenges.
Participant involvement
Participants are encouraged to actively engage in the study by providing feedback through a dedicated survey platform. The survey, accessible via https://forms.office.com/r/02iGj0g0gn, allows participants and other early adopters of Avengelus-based treatments to record observations and outcomes following each treatment cycle of their own. This collaborative approach enables researchers to gather real-time data and adjust strategies accordingly, fostering a dynamic and responsive research environment.
Looking ahead
The use of Trichoderma-based solutions holds the promise of not only controlling the spread of the pathogen but also nurturing healthier and more resilient tree populations. Be sure to look out for updates in future issues of the ARB Magazine.
Call to action
To contribute to this research endeavour, participants are invited to access the survey link provided and share their experiences and observations. Every response serves as a vital piece of the puzzle in our quest to safeguard our natural ecosystems against the threat of honey fungus.
In a world grappling with environmental challenges, collaborative initiatives such as this offer a beacon of hope, demonstrating the power of science and collective action in shaping a brighter future for generations to come.
