Unicur

Unicur (active substances: prothioconazole and fluoxastrobin) is our leading fungicide for use in bulb onions and shallots, giving you unrivalled control of downy mildew (Peronospora destructor) and reduction of bacterial rots associated with this disease. It also controls leaf blight (Botryotinia squamosa, anamorph Botryis squamosa) and has activity against Botrytis, Cladosporium, Stemphylium and Puccinia species. Combining the powerful strobilurin, fluoxastrobin with the triazolinthione, prothioconazole (tzt technology), Unicur strengthens plant health for better bulb quality from field to store.

How Unicur works

The tzt technology in Unicur advances disease control and plant health. Being a
new generation DMI, prothioconazole combines exceptional protection with sustained curative activity for powerful broad-spectrum disease control. Uniquely for a DMI it also stimulates photosynthesis and enhances nitrogen assimilation to deliver greening and physiological effects in the same league as strobilurins enhancing yield and bulb resilience to bacterial infection.

When and how to apply

For the control of downy mildew (Peronospora destructor) and for a useful level of control of leaf blight, (Botryotinia squamosa, anamorph Botrytis squamosa).
Qualified minor use recommendation: Based on limited data, useful reductions can be expected of infections caused by Botrytis, Cladosporium, Stemphylium and Puccinia species and also some reduction of bacterial rots of bulbs associated with downy mildew infections.
Apply Unicur as part of a protectant programme, at any stage from when the leaf bases begin to thicken (BBCH 40, beginning of bulb formation) until when 10% of the leaves are bent over (BBCH 47).
Follow with further applications at an interval of about 14 days according to disease pressure. 

Application to young plants may cause some transient leaf chlorosis and leaf distortion. To avoid this and maximize the yield and quality benefits from Unicur, apply from the beginning of bulb formation.
Do not apply any more than two consecutive applications of Unicur.


Programme planning

It is important to structure downy mildew control programmes for optimum disease control with resistance and residue management. Trials have shown that the best partners to alternate with Unicur are mancozeb-based products as illustrated below.

Resistance Management

Apply fungicides according to manufacturer’s recommendations for the target disease (or complex) at the specific crop growth stage indicated. Effective disease management is a critical parameter in delaying the build-up of resistant pathogen populations.

Unicur is a mixture of two fungicides with different modes of action, a strobilurin and a triazolinthione. Unicur contains fluoxastrobin, a member of the Qol cross-resistance group.

For best resistance management solo applications of Unicur should be considered as solo QoI product use. The total number of sprays in a programme therefore restricts the number of Unicur applications per crop as follows;

Total no. of spray applications per crop
5 to 7 8 to 10 11 to 12
Max. recommended Solo Qol fungicide sprays
2 3 4

Unicur should be used preventatively and should not be relied on for its curative potential.

Use Unicur as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action.

Caution: The possible development of disease strains resistant to Unicur cannot be excluded or predicted. Where such resistant strains occur, Unicur is unlikely to give satisfactory control.
