Should Devrinol 50-DF Ornamental be applied to tulips showing more than 2 inches of top growth?

Devrinol 50-DF is a herbicide primarily used for pre-emergent weed control in ornamental plants and turf. Its application timing is crucial to avoid damage to desirable plants. When it comes to applying Devrinol on tulips that show more than 2 inches of top growth, it is important to consider the growth stage of the plants.

When tulips have more than 2 inches of growth, they are typically well-established and may be sensitive to herbicide applications. At this stage, the risk of injury to the tulips increases, as they can experience phytotoxic effects from the herbicide. Hence, applying Devrinol is not recommended due to the potential for harming the plants and negatively affecting their growth and blooming.

By avoiding application during this growth stage, the health and viability of the tulips can be preserved, which is essential for maintaining ornamental quality. This understanding of herbicide application timing related to plant growth stages is critical for effective pest management in ornamental horticulture.
