WITH excellent growing conditions across most of Australia’s cereal producing areas and early identification of foliar diseases, growers are set to welcome a new higher performing fungicide to further maximise their production potential and return on investment this season.
Radial, a newly registered strobilurin-based fungicide developed by Adama has been evaluated extensively over the past four seasons and has demonstrated superior or equivalent performance against major cereal diseases compared with existing benchmark fungicides.
The new product combines the market leading strobilurin and triazole active ingredients (azoxystrobin and epoxiconazole). The dual modes of action provide persistent systemic control of major foliar diseases in wheat and barley.
Developed as a specialist, high performing cereal fungicide for Australian conditions, Radial continued its outstanding performance in trials last year. Where yield potential and disease pressure was average to high, it demonstrated a yield advantage.
In wheat, where all trial results were combined, Radial showed an average yield improvement over Soprano® (epoxiconazole) of 8 per cent. When compared to an alternative strobilurin and triazole product, Radial achieved an average 9pc higher yield due to its specific combination of strobilurin and triazole and highly optimised formulation.
Meanwhile, in an Oxford barley trial conducted by Southern Farming Systems at Westmere in Victoria last season, Radial showed excellent control of net form net blotch, with an improved result compared with other market standards. The trial was high yielding, with its mean yield at 9.4 tonnes per hectare and the Radial 420 mL/ha treatment providing the highest yield of 9.7 t/ha.
Matt Beddison, Agronomist with SMS Rural Services at Horsham in Victoria, viewed Radial’s good control of spot form net blotch and leaf scald in a local trial in Scope barley last year, while he was also particularly impressed with the crop’s green leaf retention following the treatment.
Trials were conducted in Scope barley and Yitpi wheat, with Radial applied at the late tillering stage.
“Crop canopies were quite thick and the extra green leaf area from the treatment was particularly noticeable, especially in the barley. It was a real eye opener,’’ Matt said.
“Considering the season we had last year, the soft finish would have allowed the extra green leaf area to push through to yield.’’
He said he understood the yield increase at harvest where Radial was applied was considerable.
Alistair Crawford, Adama Market Development Manager for Victoria, South Australia and Tasmania, said foliar fungicides were an integral part of cropping programs depending on variety and rainfall zone, enabling growers to maximise cereal crop yields.
“To a certain extent, yield potential and disease pressure will dictate product choice and the economics of fungicide returns. With fungicide prices having dropped significantly in recent years, even top shelf products like Radial are now very affordable compared with where they once would have been and return on investment is better than ever,’’ Alistair said.
“With the recent reduction in cost of strobilurin-based fungicides like Radial, it means growers can expect better than ever returns from their investment in a quality fungicide.’’
He said with the good growing conditions and early identification of diseases such as stripe rust and yellow leaf spot, it could be an ideal season for growers to upgrade to a higher performing fungicide like Radial to take advantage of its greater length of disease protection and improved yields.
