ProForce Duke Herbicide

Tips For Use

Application Tips:

• The 100gm pack is supplied with a 1-gram measure scoop.
• For optimal results, apply a water volume rate of 200-500L/ha.
• Duke 100WG can be transferred or ‘tracked’ by equipment or foot movement.  To minimise this risk, irrigate treated areas after application, but allow at least 4 hours for chemical uptake.
• After use, ensure spray tanks are cleaned thoroughly, according to label directions.
• To optimize results with Duke 100WG, always apply with a non-ionic surfactant or Hasten adjuvant at the recommended rate on the surfactant product label. Also, ensure the application is made to actively growing weeds and not to weeds in stress, as the movement of the herbicide through the weed may be limited, and subsequent weed control may be impacted.
• For the best suppression of winter grass, it is best to target younger weed plants. Less than 50 % control can be expected where more mature plants are established.
• For good Bahiagrass suppression, apply during summer when the turf is actively growing. Apply as soon as seed heads start to form or when it becomes a regular mowing intervention issue. Apply 2-3 times at 4-week intervals after mowing for best performance.
• Avoid mowing during the 3 to 4 days preceding or following the treatment.
• Avoid entry into treated areas until the spray has dried.
• Don’t graze treated turf or feed turf clippings from any treated area to poultry or livestock. Very toxic to aquatic plants and certain algae. Do not apply under weather conditions or from spraying equipment that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.
• Application to very dry sandy soils followed by soaking rainfall may cause turf damage. Turf damage may also be increased in highly alkaline soils (soil pH >8.5 as determined by soil in water suspension).
• Avoid application on turf that is not yet established or under stress from environmental conditions.
• Allow at least six weeks between the last application and overseeding with cool season grasses for winter cover.
• Don’t use clippings from treated areas for mulch around vegetables or fruit trees.

General Instructions:

• ProForce Duke Herbicide is a selective sulfonylurea herbicide.
• It is predominantly a foliar herbicide with less activity via the soil.
• Duke 100 WG will not reliably control weeds that emerge after spraying.
• Results are best under good growing conditions, and application to weeds or turf under stress should be avoided.

Restraints:

• Do not apply by air or through any type of irrigation equipment.
• Do not apply to turf which is under stress or which is not yet established.
• Do not use if rain is expected within 4 hours.
• Do not use it on golf or bowling greens.
• Do not make more than one application of a group 2 herbicide in a season except for Bahia grass –
  refer to the Directions for Use for Bahia grass.

Mixing:

• Ensure that the spray tank is completely clean before mixing.
• Half fill the spray tank with water, then with agitators in motion, add the correct amount of Duke 100 WG directly into the spray tank.
• Then add wetting agent or crop oil as recommended.
• Complete filling the tank with agitators in motion.
• Agitation must continue before and during spraying.
• If the pH of the water carrier is less than 5.5, use a buffer solution (ie Wilt 700) to raise the pH to 7.0.
• Do not mix Duke 100 WG with acid-forming compounds in the spray vat.
• Do not leave the spray mix standing in the vat overnight.

Application:

• Ensure spraying equipment is properly calibrated before use.
• Ensure that complete and even spray coverage of all weeds is achieved.
• Do not overlap sprayed areas.
• Apply 50 cm above the turf with flat fan nozzles and medium droplet size with the boom.

Turf Safety:

• Application to very dry sandy soils followed by soaking rainfall may cause turf damage.
• Turf damage may also be increased in highly alkaline soils (soil pH >8.5 as determined by soil in water suspension).
• Avoid application on turf that is not yet established or under stress from environmental conditions.
• Allow at least six weeks between the last application and overseeding with cool season grasses for winter cover.

Precautions:

• Mowing: Avoid mowing during the 3 to 4 days preceding or following the treatment.
• Re-entry period: Do not allow entry into treated areas until the spray has dried.

Protection Of Crops, Native And Other Non-Target Plants:

• Very toxic to aquatic plants and certain algae.
• Do not apply under weather conditions or from spraying equipment that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.
• Do not replant any crop or ornamental to treated areas other than the turf grass listed in the directions for use for a period of 12 months after application.

Protection Of Livestock:

• Do not graze treated turf or feed turf clippings from any treated area to poultry or livestock.

Protection Of Wildlife, Fish, Crustaceans And the Environment:

• Keep people and pets away from and off treated areas until spray deposits have dried.
• Do not contaminate streams, rivers or waterways with chemical or used containers.
• Do not apply if heavy rain is forecast.

Storage:

• Store in the closed, original container in a cool, well-ventilated area.
• Do not store for prolonged periods in direct sunlight.
