Tazer trial results impress

Published on 28/06/2013

Nufarm development specialist Cynthia Christie says Tazer more than met her expectations in terms of by how well it controlled rhizoctonia when applied in-furrow in potatoes recently.
“We know it’s a good product and this trial work re-confirmed our expectations. It was certainly shown to be very effective, both in decreasing the severity and incidence of lesions on potato tubers and increasing marketable yield.”
Christie has also recently carried out more local trial work on Tazer in cereals on behalf of Nufarm Australia’s R&D team.
Her results in this case showed Tazer and Amistar both provided equivalent control of stripe rust under moderate to high disease pressure and effective control of fusarium head blight under moderate-low disease pressure.
The first post-patent azoxystrobin launched in New Zealand, Tazer was developed in house by the Nufarm formulation group and has now earned its stripes in both the local market and overseas, she says.
“It’s found good favour with growers. It mixes well; people are happy with the properties of the formulation and it has become well known as a reliable, proven strobulurin fungicide, particularly in wheat where growers are looking to provide cover against ear diseases like fusarium toward the end of the season.”
Another key benefit is that Tazer comes with all its claims for different crops on one label, so that growers with a diverse range of crops don’t need to buy and store multiple formulations of the same active, she says.
This is particularly relevant where crop agronomy programmes are audited for market access purposes.
As well as wheat, barley, potatoes (in furrow), sweecorn, maize and ryegrass seed, Tazer is registered for use in potatoes for foliar applications; peas, onions, field tomatoes and grapes.
Diseases covered include late and early blight (potatoes and field tomatoes); black mould (field tomatoes); ascochyta and downy and powdery mildew (peas); downy mildew, pink rot and neck rot (onions), and powdery and downy mildew plus botrytis in grapes.
As with all fungicides ‘best practice’ should be used to minimise development of resistance.
Cynthia Christie says this means selecting correct rates, tank mixing Tazer with fungicides with different modes of action and using it no more than the recommended number
of times per growing season for the crop in question.
Tazer is a protectant fungicide with translaminar and systemic activity. It should be applied before diseases become established in crops and tank mixed with an effective curative fungicide to manage established infections.
