A recently-renewed permit granted by the APVMA (PER82104) also allows the use of Veritas for the control of Powdery Mildew in summer pulses, such as Adzuki beans, mung beans and navy beans.
ADAMA Australia Head of Portfolio, Dror Dagan, says these label extensions and permit mean Veritas is arguably the most versatile foliar fungicide available.
“Veritas controls all of the major foliar diseases that affect wheat, barley, canola, broad beans, chickpeas, faba beans, field peas, lentils, lupins and vetch,” he says.
“Importantly, Veritas combines two distinctly different modes of action for improved disease control and to allow growers to proactively address fungicide resistance.
“Australian trials have shown Veritas delivers similar or better control of foliar diseases as the current benchmarks, making it an extremely cost-effective option to protect yield potential in crops facing less disease pressure.”
Veritas contains 200g/L tebuconazole (Group 3) and 120g/L azoxystrobin (Group 11) in a suspension concentrate formulation.
Tebuconazole is rapidly absorbed into leaves and is transported acropetally to provide uniform protection throughout the plant.
Azoxystrobin inhibits spore germination and host penetration from the early stages of fungal growth and provides persistence activity against spore formation.
“The concentrations of each active were deliberately chosen to provide the optimum balance between protectant and systemic disease control,” Dror says.
“Veritas contains a higher loading of tebuconazole because DMIs provide effective control of disease during the early stages, whereas the strobilurins are best used as protectants.
“In effect, Veritas doesn’t just deliver a better outcome in terms of protection against foliar diseases, it helps to protect existing chemistry.”
For use in pulse crops, Veritas is applied at a rate of 300 mL to 1 L/ha in spray volumes of 60 to 100 litres/ha for ground application and 30L/ha for aerial spraying.
Best results will be obtained when Veritas is applied as a preventative application before significant disease pressure.
“Apply at the first sign of disease or if an infection period is forecast,” Dror says.
“Use the higher rate of Veritas if conditions favour infection, on susceptible varieties or if the crop canopy is dense.
“Ideally, Veritas should be applied in rotation with a fungicide with an alternate mode of action, however a second application can be made 14 days later if conditions favour further infection.”
