Campbelltown City Council - Noxious Weeds Profile Sheet Broad Leaf Privet - Ligustrum lucidum B road-leaf Privet is a tall shrub that grows up to 4m high. It can infest disturbed land, native bushland, moist nutrient rich sites eg. creeks, gullies, down slope of stormwater drains. It occurs on relatively undisturbed sites and hillsides on shale soils. Once established, it can totally replace a diverse mix of native plant species. During spring and early summer, large amounts of pollen are produced which cause allergic reactions in some people. The fruit of Broad-leaf Privet is also reported to be poisonous to humans. Requirements of the Noxious Weeds Act 1993 Under the provisions of the Noxious Weeds Act 1993, Broad-leaf Privet is classed as a Class 4 weed. This means that the growth and spread of the plant must be controlled according to the measure specified in a management plan published by the local control authority and the plant may not be sold, propagated or knowingly distributed. How does it spread? Mature plants can produce a million or more fruits in a favourable year. Privet berries are eaten by birds which spread the seed widely into previously non-infested gardens and bushland. Seeds can also be distributed through waterways. If these shrubs are cut off at the base, without follow up with chemical treatment, they are well known to regrow shoots from the base and often grow new plants from the roots. Methods of Control To comply with legislation, flowers and fruit must be pruned from the plant on a yearly basis. This is a time consuming procedure and it is often recommended (though not a legal requirement) that trees be completely removed. Small seedlings can be manually removed. Larger plants and clumps of Privet should be removed and chemically treated. Cut stump and paint with chemical immediately after cutting. This will prevent regrowth from the stump which will occur if the plant is not poisoned. A number of chemicals (herbicides) are available for the treatment of Privet: Chemical Rate: Spot/Boom Comments Metsulfuron methyl Apply to bushes up to 3 metres Various trade names 10g in 100L of water high; complete coverage is essential. Glyphosate + Metsulfuron Apply to bushes up to 3 metres Cut-out ® 1 pack in 100L of water high, in full leaf and actively growing; complete coverage is essential. Triclopyr Basal bark/cut stump Various trade names 1 L in 12 L of diesel application. Triclopyr + picloram Access ® 1 L in 30 L of diesel Basal bark/cut stump application. Glyphosate 360g/L Stem injection technique, as Various trade names Undiluted per label Campbelltown City Council - Noxious Weeds Profile Sheet Note: Make sure that any chemicals used are registered for the use on the weed being eradicated. READ THE LABEL - it is an offence to use a herbicide in a manner contrary to the label. Take particular care if the weed you want to eradicate is near a dam or waterway. If possible, avoid using herbicides near waterways as they can harm fish and other aquatic organisms.
