Woody weeds have long been a scourge on grazing landscapes across the country, however the arrival of capsulated herbicide products and key application technology is providing a breakthrough in control – with strong environmental benefits.

Adama Australia’s Injecta technology seals the capsules directly into woody weeds, reducing traditional herbicide usage by up to 70 per cent and limiting environmental impacts.

The technology was featured on the ABC Landline program, sparking growing interest in the system.

Plant pathologist Professor Victor Galea told the program the technology meant super giant (weed) trees could be taken out via a simple process.

“It would only take 15 minutes to treat the tree and within a year it’s totally dead,’’ he told the program.

“All the herbicide stays in the stem, so there is no environmental leakage, and so we can reduce the amount of herbicide we need to kill these weeds.’’

Di-Bak G capsules from Adama Australia, containing glyphosate, control woody weeds and unwanted trees in forestry, pasture, commercial, industrial and public service areas.

Di-Bak Parkinsonia bioherbicide has been developed to control the weed Parkinsonia aculeata which goes by a range of common names in different states, including Jerusalem thorn, parkinsonia, Barbados flower-fence, horse bean, jelly bean tree and Mexican palo verde.

Di-Bak Parkinsonia bioherbicide contains three native Australian fungi that have been isolated from plants afflicted with a naturally occurring disease known as parkinsonia dieback, which can be lethal to the plant. The injected bioherbicide causes an infection that kills the Parkinsonia weeds naturally.

Professor Galea told ABC Landline the bioherbicide could be used to provide control in areas where the disease did not occur naturally.

He said the biological control also reduced the reliance on chemicals, providing for economic and biological sustainability.

The Injecta 400 system from Adama Australia was designed specifically for use with the Di-Bak capsulated products. It provides fast and efficient delivery of the capsules into tree stems and allows treatment under various weather conditions and in challenging terrain.

The Di-Bak products are available in 200 or 1000 capsule bottles for insertion into the Injecta gun.
