DIRECTIONS FOR USE: It is a violation of Federal Law to use this product in a manner inconsistent with its labeling. [Read the entire label before using this product.] [Use only according to label instructions observing all use directions and precautions.]
NOTE: Read the "CONSUMER INFORMATION" Section of this label for important information on protecting desirable plants from potential injury.

When To Use: Apply to actively growing weeds, preferably before the seed heads form. Completely spray the foliage of the weeds and grasses you want to kill until thoroughly wet. For best results, apply on warm sunny days when the temperature is above 60°F. Weed control is accelerated by warm, sunny weather. For best results, reapply the product if rainfall or watering occurs within 24 hours after application.
Apply when the wind is calm to prevent spray from drifting to desirable plants. If desirable plants are accidentally sprayed or if spray drifts onto desirable plants, immediately wash desirable plants thoroughly with plenty of clean water. Hard-to-kill weeds may require a second application if not completely dead in 4 weeks

How To Use: This product is formulated for "spot" treatment of individual weeds and grasses or for treatment of large areas as instructed on this label (see specific site areas below). Apply with a plastic, aluminum or stainless steel tank-type sprayer.
Do not apply with galvanized or unlined steel sprayer, or through any irrigation system, or with a sprinkling can.
Using a tank-type sprayer, adjust spray nozzle to deliver a coarse spray for spot treatments. Use a fertl-lome AIR-O-MATIC Hose-End Spray or other hose-end sprayer to treat large areas such as for lawn renovation or to prepare sites for planting flower or ornamental beds, or for vegetable gardens. Apply evenly and thoroughly wet weeds and grasses.
