Unleashing the Power of Ethephon: A Revolutionary Approach to Plant Growth Control
Unleash the Power of Ethephon: A Game-Changer for Plant Growth Control
In the world of horticulture, the quest for uniform and aesthetically pleasing plants is an ongoing challenge. But here's where it gets exciting: a recent study has unveiled a powerful tool - ethephon substrate drenches - that can effectively control plant growth, offering a new dimension of control for growers.
Controlling Stem Elongation: A Precise Approach
The study focused on herbaceous perennials, evaluating the impact of ethephon drenches on stem elongation. The results were remarkable: targeted applications not only controlled plant height but also ensured overall plant health, resulting in uniform, high-quality plants ready for the retail market. This precise approach allows growers to achieve the desired aesthetic without compromising plant vitality.
Managing Growth in Annual Bedding Plants: A Compact Revolution
Building on this, a complementary study explored the effects of ethephon drenches on annual bedding plants. The findings were equally impressive: controlled applications limited excessive growth, leading to more compact, visually appealing plants. This strategy offers a cost-effective and efficient way for growers to manage plant growth, especially in greenhouse and nursery settings.
Industry Impact: A New Era of Horticulture
Effective height and growth control are not just about aesthetics; they are essential for operational efficiency and sustainability in ornamental horticulture. This research provides growers with actionable insights to enhance plant uniformity, reduce labor-intensive pruning, and improve crop marketability. By adopting these strategies, growers can embrace more sustainable and profitable production practices.
Leading the Research: A Team of Experts
This groundbreaking research was led by W. Tyler Rich, a research associate, as part of his Master of Science degree at The Ohio State University. The study was conducted to support the label expansion of Collate® 2L (ethephon), which, as of May 2025, is the only ethephon product approved by the EPA for substrate drench use and foliar sprays. These findings are a testament to the potential of ethephon in floriculture production.
W. Garrett Owen, an extension specialist and assistant professor, focuses on sustainable greenhouse nursery systems, including floriculture crop production, plant nutrition, and growth regulation. His expertise contributes to the broader understanding of these practices.
