Semera 4 SC Herbicide is an economic fast-acting herbicide that offers pre-emergence and post-emergence control on broadleaf weeds and grasses. It destroys a wide range of weeds such as Russian thistle, kochia, carpetweed, bluegrass, and pigweed. Also effective on submersed, emergent, and floating aquatic weeds. Its unique mode of action enters the targeted weeds thru foliage, disrupts chlorophyll, and makes weeds decompose rapidly. Flexible for both aerial and ground application. Compatible with a variety of post-emergent herbicides for more control. Best used on non-crop areas, conifers, reforestation sites, containers, trees, landscapes, ornamentals, and slow-moving waters. Available in an eight-ounce bottle.

This pesticide is toxic to plants . Use strictly in accordance with the drift and run-off precautions on this label in order to minimize off-site exposures .Treatment of aquatic weeds can result in oxygen loss from decomposition of dead weeds . This loss can cause fish suffocation . Therefore, to minimize this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait at least 10 to 14 days between treatments . Begin treatment along the shore and proceed outwards in bands to allow fish to move into untreated areas.
