In the heart of Ireland, researchers are exploring innovative ways to boost strawberry yields and combat diseases without relying heavily on chemical pesticides. Daniela Costa, a leading figure from the Horticulture Development Department at Teagasc in Dublin, has been at the forefront of this investigation, delving into the potential of silicon-based biostimulants. Her latest findings, published in the Journal of Sustainable Agriculture and Environment (Journal of Sustainable Agriculture and the Environment), offer a glimpse into a future where strawberry farming could be more sustainable and environmentally friendly.
Costa’s research focuses on the use of silicon-based biostimulants, a promising alternative to traditional pesticides. These biostimulants are designed to enhance crop growth and quality, potentially reducing the need for chemical interventions. The study, conducted across three commercial-style trials in glasshouse and polytunnel environments, evaluated different silicon-based biostimulant products and application methods against standard and reduced pesticide programs.
The results, while varied, provide valuable insights. “We found that the growing system had a major effect on strawberry production where biostimulants are used,” Costa explains. “The positive effects of biostimulant use were only noted in the polytunnel system.” This suggests that the effectiveness of silicon-based biostimulants may be influenced by the growing environment, a factor that could significantly impact commercial applications.
The trials revealed that while certain parameters, such as total weight and total yield, responded positively to silicon-based biostimulant application, these improvements were not consistent across all trials. Moreover, the overall yield increases did not translate into higher marketable yields. This inconsistency highlights the need for further research to optimize the use of biostimulants in different growing conditions.
One of the most critical aspects of the study was the comparison of biostimulants with traditional pesticides in disease control. The results were clear: pesticides remain more effective than biostimulants in reducing the incidence of fungal diseases like grey mould and powdery mildew. This finding underscores the ongoing challenge of finding sustainable alternatives to chemical pesticides that can match their efficacy.
Despite these challenges, Costa’s work is a significant step forward in the quest for more sustainable agricultural practices. “This research expands our understanding of the effectiveness of silicon biostimulants in strawberry production and disease management,” she notes. The insights gained from this study could pave the way for future developments in the field, potentially leading to more environmentally friendly and economically viable farming practices.
As the agricultural industry continues to seek sustainable solutions, the role of biostimulants in crop production and disease management will likely become increasingly important. Costa’s research, published in the Journal of Sustainable Agriculture and the Environment, provides a foundation for further exploration and innovation. By understanding the nuances of biostimulant use, farmers and researchers can work towards a future where strawberry farming is not only productive but also environmentally responsible. The journey towards sustainable agriculture is complex, but with each study like Costa’s, we move one step closer to a greener, more resilient future.
