Does Devrinol 50-DF Ornamental control both germination and established weeds?

Devrinol 50-DF is primarily used as a pre-emergent herbicide, which means it is specifically designed to inhibit the germination of weed seeds. This herbicide works by affecting the physiological processes that are crucial for seedling development, preventing new weeds from establishing themselves.

It does not effectively control established weeds, as these plants are already past the germination stage. Established weeds typically require different types of herbicides that can target their growth and development. Therefore, the statement that Devrinol 50-DF can control both germination and established weeds is inaccurate. Understanding the specific functions of herbicides is essential for their effective use in ornamental and turf management.
