Jonathan McDonald, ADAMA’s Market Development Manager for Queensland and the Northern Territory, said legislation introduced more than seven years ago to reduce run-off to the Great Barrier Reef has changed the way crop protection inputs are used by canegrowers.
“Growers are using more residual herbicides to reduce the number of passes over paddocks to control weeds. Some growers are getting away with just one application after the residual herbicide,’’ Jonathan said.
“With the move away from burning prior to harvest in most growing regions in the industry, there is also the need for herbicides to move through trash blankets.’’
ADAMA’s Bobcat® i-MAXX herbicide has been increasingly adopted by growers throughout industry. It combines the strength of two active ingredients for extended residual control and herbicide resistance management. Its performance in both field trials and extensive commercial use demonstrates the strong and broad-spectrum control it provides on a range of grasses and broadleaf weeds in plant and ratoon crops, including barnyard grass, summer grass, liverseed grass, blue top and Ipomea vine species.
A new soluble granule formulation, Bobcat i-MAXX SG launched in 2018, providing growers with a higher loaded product and a more efficient way of applying the active ingredients. A new use pattern was also added to the label which enables growers to spot spray guinea grass using hand held equipment or optical spray technology.
ADAMA’s General Manager of Technical and Development, Andrew Horsfield, said ADAMA is committed to a long-term investment in innovation in the sugar industry.
Andrew said since 2010, a key focus had been to ensure growers have access to effective new products to minimise the effect of any restrictions on the use of existing products such as Diuron.
He said the company was focused on evaluating and launching new herbicides for the sugar industry to provide growers with a range of modes of action to manage weeds efficiently.
Recent work has focused on extending the registration of Palmero® TX into sugarcane. Palmero TX is a co-formulation of isoxaflutole and terbuthylazine, controlling a wide range of grasses and broadleaf weeds. This will be the first registration of a terbuthylazine product for sugarcane in Australia and registration is expected in late 2019 or early 2020.
Andrew said that the use of Palmero TX increases the weed spectrum and activity compared with solo isoxaflutole products like Palmero 750. By formulating as a mixture, it eliminates the need to tank mix with another residual herbicide.
“Palmero TX, will provide a genuine rotational product for Bobcat i-MAXX and Bobcat Combi,’’ Andrew said.
“We are also screening a lot of other active ingredients – some that have never been used in cane, some that are registered for cane overseas and some that are registered for other crops in Australia.
“We understand that due to the range of challenges faced by cane growers, we need to provide a flexible product portfolio.’’
