Per Acre

1.2 to 2.4 lb.

1.3 to 2.6 pt.

Per 1,000 sq. ft.

0.5 to 1.0 fl. oz.

Major Weeds Controlled: Some annual grasses and some annual broadleaf weeds and yellow nutsedge.

Major Weeds Not Controlled: Germinated weeds.

For Best Results: Apply Pennant Magnum in sufficient carrier to obtain thorough coverage. Apply before grass, broadleaf weeds, or yellow nutsedge emerge or after existing weeds have been removed.

Cautions and Precautions: Do not use in greenhouses or other enclosed structures. Do not apply under conditions that favor runoff or wind erosion of soil containing this product to non-target areas. Do not exceed 4.2 pints per acre per year.

Residual Activity: High stability on soil, moderate persistence.

Volatility and Leaching Potential: Leaching generally is insignificant when soil organic matter is greater than 2 percent. Volatilization is generally low, but losses can be significant under certain conditions. Do not apply in enclosed structures.

Symptoms and Mode of Action: As weeds grow through the chemical barrier formed on soil surface, they are killed. Perennial weeds are usually vigorous enough to grow through.
