Overview
Daminozide is a synthetic plant growth regulator that has been widely used in agriculture since the 1960s. It is primarily known for its ability to control plant height and improve crop yield. The chemical works by inhibiting gibberellin biosynthesis, which slows down cell elongation in plants. This makes it particularly useful for producing compact, sturdy plants with enhanced flowering and fruiting capabilities. Initially developed by the Uniroyal Chemical Company, daminozide gained popularity under the trade names B-Nine and Alar. Its applications span across ornamental plants, fruit trees, and vegetable crops. Despite its effectiveness, its use has been controversial in some regions due to health and environmental concerns.
Physical and Chemical Properties
Daminozide is a white crystalline solid with a molecular weight of 160.17 g/mol. It has a melting point range of 154-156°C and is highly soluble in water, making it easy to apply as a foliar spray. The compound is slightly soluble in organic solvents like ethanol and acetone. One of the key chemical properties of daminozide is its stability under normal storage conditions. However, it can degrade when exposed to high temperatures or strong acids and bases. The compound’s ability to inhibit gibberellin biosynthesis is central to its role as a plant growth regulator.
Main Applications
Daminozide is primarily used in agriculture to regulate plant growth and improve crop quality. It is commonly applied to ornamental plants like chrysanthemums and poinsettias to produce compact, bushy growth. In fruit production, it enhances the color and firmness of apples and cherries, delaying ripening to extend shelf life. The chemical is also used in vegetable crops such as tomatoes and cucumbers to promote uniform fruit setting. Its ability to reduce plant height makes it valuable for greenhouse and nursery operations, where space is often limited. However, its use in food crops has been restricted in some countries due to regulatory concerns.
Safety and Storage
Daminozide should be handled with care to avoid inhalation or skin contact. Personal protective equipment, including gloves and masks, is recommended during application. The compound is classified as slightly hazardous if ingested or inhaled, and prolonged exposure should be avoided. For storage, daminozide should be kept in a cool, dry place away from direct sunlight. Containers must be tightly sealed to prevent moisture absorption. Disposal should follow local regulations for agricultural chemicals to minimize environmental impact.
B2B Procurement Guide
When procuring daminozide, it is essential to verify the supplier’s compliance with agricultural chemical regulations. Key factors to consider include purity levels, typically ranging from 85% to 98%, and the availability of certification documents. Prices vary depending on quantity and supplier, with bulk purchases often offering cost savings. Procurement professionals should also assess the supplier’s reputation and delivery reliability. Given the regulatory restrictions in some regions, buyers must ensure that the product meets local legal requirements. Technical support and application guidelines from the supplier can be valuable for effective use.
