ADAMA Australia Herbicide Portfolio Manager, Stuart Moncrieff, says Palmero TX is a unique co-formulation of the active ingredients, terbuthylazine (Group C) and isoxaflutole (Group H).
“This is the first registration for the use of terbuthylazine for sugarcane in Australia, so it’s big news for the industry,” he says.
“Terbuthylazine is a new triazine herbicide that controls target weeds by inhibiting a specific step in photosynthesis.
“Isoxaflutole also inhibits an enzyme involved in photosynthesis but at a different stage of the process.
“Combining these two actives into one, easy-to-use water dispersible granule formulation reduces the need to tank-mix to broaden the weed spectrum.
“The combination of Group C and Group H herbicides are often synergistic due to their combined effects on inhibiting photosynthesis in target weeds.”
Palmero TX can be applied as a directed spray in plant and ratoon cane or as a broadcast application in ratoons after harvest up to the two-leaf crop stage.
Trials conducted in Australia between 2015 and 2019 demonstrate that Palmero TX provides equivalent or superior control when compared to industry standard tank-mixes of key grasses and broadleaf weeds up to three months after treatment.
Stuart says Palmero TX is an ideal rotation partner for ADAMA Australia’s existing sugarcane herbicides, Bobcat® i-MAXX SG (Group B/C) and Bobcat® Combi (Group C), for sustainable weed control in sugarcane.
“It’s important that growers use a range of management strategies to control weeds,” he says.
“Rotating between herbicides with different modes of action reduces selection pressure for herbicide resistance.
“For resistance management, controlling emerged weeds and improved crop safety, we recommend that Palmero TX and Bobcat i-MAXX are always applied in a tank-mix with ADAMA’s paraquat herbicide Spraytop®.”
Stuart says ADAMA is continuing to invest in innovation for the sugarcane industry.
“In particular, we are focussed on developing alternatives to offset restrictions on the use of existing herbicides, such as 2,4-D and Diuron.
“Applying a product with a strong residual on target weeds in plant and ratoon cane, such as Palmero TX or Bobcat i-MAXX, reduces the frequency or need for 2,4-D applications during the season,” he says.
The use of Palmero TX will be supported by the free ADAMA ReefAware app, a simple ‘stop-go’ decision support tool that determines which herbicides can be applied to a specific paddock at a specific time of year.
“We’re committed to helping growers and agronomists to implement effective and sustainable weed control programs,” Stuart says.
“ReefAware allows growers and agronomists to select and use ADAMA products with confidence.”
