Is it true that Devrinol 50-DF Ornamental applications should utilize rainfall if irrigation is unavailable?

Devrinol 50-DF is a pre-emergent herbicide commonly used in ornamental plant applications to control weed growth by inhibiting seed germination. When applying this product, activating it in the soil is crucial for its effectiveness. Rainfall plays an essential role in this activation process, as it helps to incorporate the herbicide into the soil, ensuring that it can effectively form a barrier that prevents weed seeds from germinating.

If irrigation is unavailable for activating Devrinol, relying on rainfall becomes an important strategy. Adequate moisture from rainfall allows the herbicide to penetrate the soil and provides the necessary conditions for its herbicidal activity. Therefore, encouraging the utilization of rainfall in the absence of irrigation is sound practice for achieving optimal results with this herbicide.

The other choices do not align with the best practices for using Devrinol. Stating that it's only true if the soil is dry or under specific temperature conditions limits the applicability and efficiency of the herbicide. The need for water to activate the herbicide stands regardless of soil moisture levels or temperature, indicating that moisture from rainfall is beneficial whenever irrigation cannot be applied.
