Semera 51% WDG is a fast acting pre-emergent and post-emergent herbicide that provides residual control of selective broadleaf weeds and grasses in warmer season turf grasses that are dormant in areas such as golf courses, sod production farms, and areas similar. The herbicide does not volitive and move off target which makes it effective in helping to maintain bare ground non-crop areas. Semera is also used to control selective emergent, floating, and submersed aquatic weeds in slow moving or quiescent bodies of water. To be the most effective, application to bodies of water should take place when weeds are young and actively growing and the pH of the water is less than 8.5. Semera 51% is a water disposable granule that is a great tank mix partner and application options are flexible.

For Terrestrial Uses
Pre-emergence Application: Weed control is the most effective when it is applied to weed-free and clean soil surfaces before weed emergence. It is necessary to apply Semera in a moist environment, if it is too dry the effectiveness of the herbicide may be reduced. If the proper amount of moisture is not received post application, weed control can still be maintained by shallow cultivating
Post-emergence Application: Weed control is the most effective when Semera is combined with a surfactant to weeds that are less than 2 inches high. Apply only to actively growing weeds in sunny weather and temperatures are greater than 65 degrees. Semera is rainfast one hour after application, so do not apply if rainfall is expected within one hour after.
For Aquatic Uses
Pre-Emergence Application: Use at least 10 gallons of spray solution per acre when using boom sprayers to ensure a uniform coverage. Apply 50-100 gallons of spray solution per acre when making backpack applications.
Post-Emergence Application: Use at least 15 gallons of spray solution per acre when using boom sprayers to ensure a uniform coverage. If there the vegetation is dense or if there is a heavy residue on the soil surface, apply atleast 20 gallons per acre. Apply 1 gallon of spray solution for every 500-1000 sq.ft when using a backpack sprayer.
