Product Information
SedgeMaster is a sulfonylurea herbicide that works by inhibition  of acetolactate synthase (ALS). Many factors such as application rate, weed species, weed pressure, conditions of weeds including size  and  climatic  factors  impact  the  degree  of  weed  control. 
Applications made to actively growing weeds at the early stages of  development  as  described  below  will  optimize  performance.   
In  post-emergent  weed  applications,  early  treatment  is  best  to  control the weeds vying (competing) with the crop.

SedgeMaster is  quick  to  act  on  targeted  weeds  by  stunting  growth  allowing  the  crop  to  overtake  the  development  of  the targeted weeds.
Once the development of the targeted weeds is stunted, the leaves and growing point begin to discolor and die.  Complete control typically occurs within 7 to 14 days depending on  the  weed  size,  species  and  growing  conditions.  Depending  on  the  stage  and  development  of  the  targeted  weeds,  control generally takes place in 7 to 14 days.

Resistant Management Guidance
SedgeMaster is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to SedgeMaster and other Group 2 herbicides. Weed species with acquired resistance to  Group  2  may  eventually  dominate  the  weed  population  if  Group  2  herbicides  are  used  repeatedly  in  the  same  field  or  in  successive years as primary method of control for target species.
This may result in partial or total loss of control of those species by SedgeMaster or other Group 2 herbicide.

To delay resistance consider:
•  Avoiding the consecutive use of SedgeMaster or other target site action Group 2 herbicides that have a similar target site of action, on the same weed species.
• Using tank-mixtures or premixes with herbicides from different target  site  of  action  Groups  as  long  as  the  involved  products  are  all  registered  for  the  same  use,  have  different  sites  of 
action, and are both effective at the tank mix or prepack rate on the weed(s) of concern.
•Basing herbicide use on a comprehensive IPM program.
•Monitoring treated weed populations for loss of field efficacy.
•Contacting   your   local   extension   specialist,   certified   crop advisor,   and/or   manufacture   and/   or   integrated   weed  management  specialist  for  specific  crops  and  resistant  weed  biotypes.


Since this product forms a suspension in water, it is important to maintain good agitation during mixing and spraying. If the spray suspension is allowed to settle for a short period of time, be sure to agitate the spray suspension for a minimum 10 minutes. Apply spray solutions within 24 hours after mixing.

Mix 0.03 ounces (0.9 gram) of this product (using the measuring scoop  provided)  in  1  -  2  gallons  of  water  to  treat  1,000  sq. ft. 
Add 2 teaspoons (1/3 fluid ounce) of nonionic surfactant per gallon of  water.  Measured  this  product  as  a  level  and  not  a  rounded  scoop.  Mix  or  shake  thoroughly  for  at  least  two  minutes  to 
completely  disperse  this  product. To  ensure  that  this  product remains  thoroughly  mixed  while  spraying,  occasionally  shake  the spray suspension.

Spray  additives  such  as  nonionic  surfactant  (NIS),  or  Crop  Oil Concentrate  (COC)  are  used  with  SedgeMaster to  improve  performance. The typical nonionic surfactant contains a minimum of 80% NIS and is accepted by the EPA for use on food crops. The use rate is 0.25 to 0.5% NIS concentrate (1 to 2 quarts per 100 gallons of spray mixture). Always use NIS in the spray mixture. For specific details, consult the use site directions.
