Boom Spraying

Gorse Management

Boom spraying uses a long sprayer arm attached to a tractor or vehicle to treat large areas with gorse in a short time. Boom spraying is best for treating regrowth if you have already treated a large area of gorse. Not all herbicides can be sprayed with a boom spray because of the ‘blanket coverage’ it provides.

When

Boom spraying works best when plants are actively growing because this distributes the herbicide throughout the plant. Gorse does not actively grow in winter and herbicides are less effective if plants are stressed by extreme cold or heat. The best time to boom spray is from spring to early summer and after autumn rain, before gorse flowers. For best results, treat gorse before it flowers and produces seed pods to prevent the seed being spread. When gorse is in seed take care as dropped seeds can be picked up from the ground by machinery and vehicles and transported around your property. Regrowth should be at least 40 centimetres high before treating so it can absorb the herbicide effectively.

Pros & Cons

Boom spraying is ideal for large areas of accessible land and for controlling regrowth. Care must be taken not to spread gorse from vehicles to other areas.

Follow up

Establish fast-growing pasture or revegetate with plants to outcompete gorse seedlings. Check for gorse regrowth and treat. Regrowth should be at least 40 centimetres high before treating so it can absorb the herbicide effectively.

Cultural Heritage Awareness

Landholders must be careful to avoid further damage to the environment (including waterways) and Aboriginal cultural heritage sites when using machinery. Be aware of your legal obligations and obtain the necessary permits. Aboriginal Cultural Heritage may be found during works at any time, at any place.

If suspected heritage is discovered, work is to cease and a Preliminary Report Form must be completed and sent to vahr@dpc.vic.gov.au. If you are unsure, seek advice from Agriculture Victoria, Department of Environment, Land, Water and Planning, First Peoples – State Relations (formerly Aboriginal Victoria) or your local council.
