Monitoring the success of herbicide applications is very important to identify any areas that require follow-up treatment.



Controlling with herbicides

Herbicides are highly effective tools for controlling blackberry, and their use is the most reliable method for achieving local eradication.

There are a large range of herbicides available for blackberry control. The effectiveness and suitability of each herbicide varies depending on your situation and management goals. Four factors should be considered when controlling blackberry with herbicides:

1. There are two main modes of action. Most herbicides used for blackberry are absorbed through the foliage, stems or leaves, but some are also absorbed through the roots and can remain active in the soil for some time.

2. A large proportion of a blackberry plant is underground (crown and roots), therefore herbicides will need to be translocated here to kill the plant. Selection of the most appropriate chemical and application technique is important.

3. A number of different techniques are available to apply herbicides, for example, foliar, cut stump, granules or gel, and aerial applications. The most suitable will depend on a range of site factors such as accessibility, other vegetation, cost, resources and proximity to waterways. Be wary of legislation that may require an accreditation for applying some herbicides.

4. The level of control with herbicides is variable and is influenced by a range of factors, including application, timing, plant condition and age, weather, plant species, water quality, and type and rate of herbicide. Always refer to the product label before using any herbicides.
