Spot Treatment (spray solution)

3 to 10%

Major Weeds Controlled: Nonselective herbicide; nearly all plants are controlled or suppressed.

Major Weeds Not Controlled: Older annual and perennial weeds will only be suppressed with top kill. Grassy weeds are likely to regrow.

For Best Results: Ensure thorough wetting and complete coverage of all unwanted vegetation, but avoid runoff. Apply in warm, dry weather for most rapid results. Use higher rates for weeds greater than six inches in height or in flowering stage.

Cautions and Precautions: Avoid contact with desirable vegetation. Do not apply using hose-end sprayers. Keep people and pets off treated areas until dry. The odor can be offensive. Avoid skin and eye contact because irritation is likely.

Residual Activity: No soil residual activity has been reported.

Volatility and Leaching Potential: Volatility and leaching are negligible.

Symptoms and Mode of Action: Disrupts cell membranes causing rapid cell desiccation. On a sunny, warm day initial symptoms of water-soaked foliage may be observed within minutes.
