GENERAL INSTRUCTIONS CONTINUED

Nufarm Sempra Usage:

  • Nufarm Sempra is a dry flowable granule that disperses in water.
  • It is designed for selective post-emergence control of Nutgrass in Sugarcane, Corn/Maize, and Sorghum.
  • It is also effective for selective post-emergence control of Nutgrass and Mullumbimby couch in Turf and Navua sedge in pasture.
  • Additionally, it can be used for Nutgrass control in Cotton using shielded sprayers, and Banjo or Supercharge Elite should always be added for maximum control.

Symptoms of Weed Control:

  • Gradual yellowing of foliage and seed heads followed by desiccation.
  • Initial symptoms may take 7-10 days to be noticeable, with full effects occurring 4 to 6 weeks after treatment.
  • Apply to actively growing weeds when new growth has reached a minimum of 5cm for Nutgrass and Navua sedge, or 2cm for Mullumbimby couch.
  • Apply follow-up treatments if sufficient new growth warrants re-treatment.
  • For Navua sedge, follow-up treatments must be applied 8-12 weeks after the first treatment for good control.
  • Irrigation or rainfall within two hours of application will reduce control, and drought stress after treatment may also reduce control.

Mixing:

  • Add Nufarm Sempra gradually to a part-filled spray tank while maintaining continuous bypass agitation.
  • Add the surfactant near the end of the filling process to avoid excessive foaming.
  • Remove the hose from the mixing tank immediately after filling to avoid siphoning back into the water source.
  • If allowed to stand, ensure that the mixture is thoroughly agitated before recommencing spraying.
  • Use the mixture within one day.

Adjuvant Addition:

  • Nufarm Sempra must be applied with Banjo or Supercharge Elite at 1 L/100L to ensure uptake.
  • For handheld or knapsack application, add Banjo or Supercharge Elite at 100 mL/10L of water.

Sprayer Clean-up: Before applying products other than Nufarm Sempra, clean the sprayer:

  1. Drain the tank and flush equipment with water for a minimum of 10 minutes, including hoses, filters, and booms.
  2. Fill the tank with clean water and add chlorine bleach (contains 4% chlorine) at the rate of 300 mL/100L of water. Flush through the boom and agitate for 15 minutes.
  3. Repeat step 2 above.
  4. Remove all nozzles and screens and clean thoroughly.
  5. Rinse the tank thoroughly with clean water to remove traces of chlorine bleach.
  • Caution: DO NOT use chlorine bleach with ammonia. Rinse equipment that contained liquid fertilizer with ammonia before adding chlorine bleach to avoid the release of irritating gas.

Following Crops:

  • Time intervals before planting following the last application of Nufarm Sempra:
    • Corn/Maize, Sorghum, Sugarcane: 2 months
    • Wheat, Pastures (Brachiaria decumbens, Brachiaria humidicola, Setaria spp., Pangola spp.): 3 months
    • Cotton: 4 months
    • All other crops (except sugarbeet): 24 months
    • Sugarbeet: 36 months

Resistance Warning:

  • Nufarm Sempra is a Group 2 herbicide inhibiting acetolactate synthase, belonging to the sulfonylurea group.
  • It is essential to manage resistance as Nufarm Sempra is a Group 2 herbicide.
  • Some naturally occurring weed biotypes resistant to Nufarm Sempra and other Group 2 herbicides may exist.
  • Resistant weeds may dominate the weed population if Group 2 herbicides are used repeatedly.
  • There is no liability for losses resulting from the failure of Nufarm Sempra to control resistant weeds.

Additional Information:

  • It is crucial to follow all recommended procedures, including the cleaning of equipment, before applying products other than Nufarm Sempra.
  • Follow specific guidelines for tank mixtures and compatibility with other products.
  • Consider environmental precautions, such as preventing contamination of streams, rivers, or watercourses.
  • Take precautions regarding the protection of crops, non-target plants, livestock, wildlife, fish, crustaceans, and the environment.
  • Store the product in a cool, well-ventilated area, and follow proper disposal procedures for containers.
  • Review safety directions and precautions, including protective measures during application and re-entry periods.
