To unlock the potential of unproductive pastureland which has been overrun by large-scale infestations of blackberry, turn to GARLON* 600 for the economy job. It won’t affect grasses and there is no need to move your livestock during application. This will help you improve your pasture economically and bring this hardy noxious weed under satisfactory control.

GARLON 600 is not a residual product and follow-up applications will be required. As part of a follow-up programme, or for a superior performance against blackberry, we would recommend our product GRAZON* Double Strength (DS). GRAZON DS has a residual action, a broader spectrum and a superior efficacy to GARLON 600. It may be a little more expensive but it will give you a premium job.

So, if you are trying to get large areas of blackberry under control economically, use GARLON 600. It’s the herbicide for the economy job. And for the follow-up eradication program on smaller patches, use GRAZON DS for the premium job.

The result of this program should be revitalised pastures of profitable grazing land for your livestock.

GARLON 600 weed control programs should be conducted according to our Product and Environment Policy, a copy of which is available on request from DowElanco.

THE PROGRAMMED APPROACH TO BLACKBERRY CONTROL

A programmed approach to blackberry control over several years combining both chemical treatment and management is necessary because of the persistent nature of the weed. A single chemical treatment will not completely control blackberry, as some regrowth will undoubtedly be experienced. If follow up spraying is not carried out, bushes will return to their original condition.

TIMING

GARLON 600 can be applied from late spring to early autumn for most effective control provided sufficient soil moisture is present and the blackberry is growing actively. The use of GARLON 600 under extremely dry conditions is not recommended as considerable regrowth may occur. When goats or slashing have been used to control blackberry, the bushes should be allowed one year’s growth before spraying.

WEATHER CONDITIONS

Foliar absorption following spraying with GARLON 600 is sufficiently fast that light rain within one hour is unlikely to adversely affect blackberry control.

APPROACH TO DIFFERENT SITUATIONS

Situation 1 – Dense Blackberry covering large areas.

Option A
Year 1: Use GARLON 600 to reduce the blackberry to more manageable proportions.
Year 2: Use DowElanco GRAZON* DS to treat regrowth greater than 1 metre in length.
Year 3: Check treated areas for any regrowth and spot spray with GRAZON DS.

Option B
Year 1: Use GRAZON DS at recommended rates. Because of its superior efficacy, regrowth will be minimal. You will save time and money with less retreatments.

Situation 2 – Blackberry in areas with associated woody weeds.

Where you have blackberry growing in areas where there are other woody weed problems such as African boxthorn, gorse, hawthorn, lantern or sweetbriar, use GRAZON DS. It is effective against all these species.

Situation 3 – Blackberry growing next to desirable plants.

GARLON 600 can be used to control blackberry growing in association with desirable plants such as Eucalypts provided these are not directly sprayed or contacted by spray drift.

Situation 4 – Difficult to kill blackberry.

For difficult to kill blackberry varieties or hybrids, use GRAZON DS for the premium job.

MANAGEMENT AFTER SPRAYING

Removal of dead canes by burning or crushing is an important feature of the blackberry control programme. However, these practices should not be carried out earlier than six months after spraying.

The removal of dead canes makes retreatment easier, reduces the amount of herbicide required for follow-up treatments and enables stock to graze in the pasture growth that follows spraying. Where can removal leaves bare soil, oversowing with a recommended pasture mixture for the area is advisable.

Regrowth should be allowed to reach 1 metre in length before respraying is commenced.

Grasses are not normally affected by high-volume spraying in water. Livestock can safely remain in the paddock during and after treatment, as no withholding period is applicable.

Residues of GARLON 600 in the soil are shot lived.
