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.
