Daminozide is primarily used as a plant growth regulator in agriculture. It is applied to control the height and promote the flowering of ornamental plants, ensuring they remain compact and visually appealing. This chemical is particularly effective in enhancing the quality of fruits by improving their color, size, and shelf life. Additionally, daminozide is utilized to delay the ripening process, which is beneficial for extending the harvest period and reducing post-harvest losses. Its application is common in the cultivation of fruits like apples and cherries, as well as in the production of greenhouse crops. Proper usage helps in achieving desired plant characteristics and optimizing crop yield.
