• Do not apply to waterlogged soils.
• Do not irrigate to the point of runoff for at least 3 days after application.
• Do not apply if heavy rain has been forecast within 48 hours.
• Do not apply to golf putting greens or bowling greens.
• Do not apply to newly laid turf sods. Wait until the turf has established.

Spray Drift Restraints:

• Specific definitions for terms used in this section of the label can be found at apvma.gov.au/spraydrift
• Do not allow bystanders to come into contact with the spray cloud.
• Do not apply in a manner that may cause an unacceptable impact to native vegetation, agricultural crops, landscaped gardens and aquaculture production, or cause contamination of plant or livestock commodities, outside the application site from spray drift. 
• Wherever possible, correctly use application equipment designed to reduce spray drift and apply when the wind direction is away from these sensitive areas.
• Do not apply unless the wind speed is between 3 and 20 kilometres per hour at the application site during the time of application.
• Do not apply if there are hazardous surface temperature inversion conditions present at the application site during the time of application. 
• Surface temperature inversion conditions exist most evenings, one to two hours before sunset and persist until one to two hours after sunrise.

Re-entry Period:

• General Public: Do not allow public re-entry into treated areas until the spray has dried.
• Ground Staff / Professional Operators: Do not enter treated areas until the spray has dried, unless wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical-resistant gloves.

General Instructions:

• Pennmag is a pre-emergent herbicide for the control of various annual grasses and broadleaf weeds. 
• Pennmag is safe to use on established and recovering turf. 
• The product acts mainly through shoot (coleoptile) absorption. 
• Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the top 3 to 4 cm of soil, where it must be present at the time of weed germination. 
• If applying Pennmag to warm-season turf during the transition from winter to spring, avoid applications when soil temperatures remain low. 
• Turf recovery will be greater if applied when soils have already commenced warming.

Mixing:

• Add Pennmag directly to a spray tank containing 2/3 of the required spray volume. 
• Add the rest of the water and ensure the mix is thoroughly agitated before application. 
• Maintain agitation during application.

Application:

• Apply before weed emergence. 
• Total application volume should be a minimum of 750 L/ha. 
• Use coarse droplets (eg Air Induction flat fan 08 nozzles). 
• Spray nozzles should be uniformly spaced and of the same size, and should provide accurate and uniform application. 
• To ensure accuracy, calibrate the sprayer at the beginning of the season before use and recalibrate frequently. 
• Observe sprayer nozzles frequently during the spraying operation to ensure that the spray pattern is uniform. 
• Avoid overlapping of spray runs.
• Ensure that boom height does not exceed 50 cm above the leaf blades of the turf. 
• Irrigate after application.
  • Fallow soil: When applying to fallow soil, follow application with irrigation of at least 3 mm within 24 to 48 hours.
  • Established turf: When applying to established turf (full or recovering canopy), immediately follow application with at least 3 mm of irrigation.

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

• 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.

Protection Of Wildlife, Fish, Crustaceans And Environment:

• Toxic to fish. Do not contaminate streams, rivers or watercourses with the chemical or used containers.

Storage:

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

Safety Directions:

• Harmful if inhaled. 
• Do not inhale spray mist. 
• It will damage the eyes. 
• Avoid contact with the eyes. Repeated exposure may cause allergic disorders. 
• Sensitive workers should use protective clothing.
• When opening the container, preparing and using the prepared spray wear:
  • goggles
  • a disposable mist face mask covering the mouth and nose
• If the product gets in the eyes, wash them out immediately with water. 
• Wash your hands after use.
