What is it?

Oryzalin is a dinitroaniline herbicide, known for its orange-yellow crystalline appearance. It is widely used in agricultural settings, home gardens, and landscaped areas to control unwanted vegetation. As a pre-emergent herbicide, it is applied to the soil to target weed seeds before they can emerge and establish.

How does it work?

Oryzalin is absorbed by the roots and shoots of germinating weed seeds. By interfering with microtubule formation, it disrupts cell division, effectively stopping weed growth before it starts. Since it is a pre-emergent herbicide, it must be applied before weed seeds germinate for optimal effectiveness.

Benefits

• Effective Pre-emergent Control: Prevents the growth of many annual grasses and broadleaf weeds.
• Long-Lasting Residual Activity: Provides extended protection against weeds, often lasting several months depending on environmental conditions.
