Siltra XproPlant Protection Product ComparisonPlant Protection Product ComparisonReport inaccuraciesReport inaccuracies

A fungicide for the control of stem-base, foliar and ear diseases in winter and spring barley and winter and spring oats.

It combines the best azole for barley disease control, prothioconazole, with new generation SDHI bixafen to form the new standard for Rhynchosporium, net blotch, brown rust and Ramularia control.  SiltraXpro delivers exceptional crop health and crop greening benefits for optimum grain quality, it is fully accepted by MAGB and the BBPA for use on malting crops.

WINTER and SPRING BARLEY, WINTER and SPRING OATS
Maximum individual dose: 1.0 litres product per hectare
Maximum number of treatments: Two per crop
Latest time of application: up to beginning of flowering

DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Siltra Xpro is a mixture of a carboxamide and triazolinthione fungicide recommended for control of a wide range of diseases on winter and spring barley and winter and spring oats.
PROTECT FROM FROST

CROPS
Siltra Xpro may be used on all commercial varieties of winter and spring barley and winter and spring oats.

RATE OF USE
Apply SiltraXpro at 1.0 litre per hectare in cereals.
The maximum number of treatments is two per crop.

APPLICATION
Water volume
Apply SiltraXpro in 100-300 litres water per hectare. The higher spray volumes are recommended where the crop is dense or disease pressure / risk is high to ensure good penetration to the lower leaves and stem bases. Disease control may be compromised by reducing water volumes, where good spray coverage is difficult to achieve. A spray pressure of 2-3 bar is recommended.

Spray quality
Apply as a MEDIUM spray quality (as defined by BCPC).

Latest Permitted Timing
In barley and oats SiltraXpro may be applied at any stage up to beginning of flowering.

Mixing
Thoroughly shake the pack before use.
Add the required quantity of Siltra Xpro to the half-filled spray tank with the agitation system in operation and then fill to the required level. Continue agitation at all times during spraying and stoppages until the tank is completely empty. Spray immediately after mixing.

General
Sprayers should be thoroughly cleaned with water and detergent after use, and filters and jets checked for damage and blockages.
Boom height should be adjusted to ensure even coverage of the crop, particularly at later growth stages. The correct height is one at which the spray from alternate nozzles meets just above the crop, In dense crops, at later growth stages, higher water volumes should be used.

DISEASES CONTROLLED
Barley
Eyespot (reduction of the incidence and severity), powdery mildew, yellow rust, brown rust, ear disease complex (moderate control of Fusarium ear blight and reduction of sooty moulds), Rhynchosporium, net blotch, Ramularia.

Oats
Eyespot, crown rust and mildew.

APPLICATION TIMING
CEREALS
Eyespot (Oculimacula spp.)
Spray in the spring at the first sign of disease, from when the leaf sheaths begin to become erect until the 2nd node is detectable (GS 30-32).

Powdery Mildew (Blumeria graminis)
Apply SiltraXpro at the first signs of disease. Where disease pressure remains high application may be repeated.

Yellow Rust (Puccinia striiformis)
Apply SiltraXpro at the first signs of disease. A second application may be made 2-3 weeks later if re-infection occurs. Applications made to established infections are likely to be less effective.

Brown Rust (P. hordei)
Apply SiltraXpro at the first signs of disease. A second application may be made 2-3 weeks later if re-infection occurs. Applications made to established infections are likely to be less effective.

Crown Rust (Puccinia coronata)
Apply SiltraXpro at the first signs of disease. Siltra Xpro controls crown rust in winter and spring oats. A second application may be made 2-3 weeks later if re-infection occurs. Applications made to established infections are likely to be less effective.

Ear Disease Complex
Apply SiltraXpro soon after ear emergence up to the beginning of flowering for moderate control of Fusarium ear blight in barley and reduction of sooty moulds. Control of ear diseases can result in cleaner, brighter ears.

Leaf Blotch (Rhynchosporium secalis)
Apply SiltraXpro in spring at the first signs of disease. For severe infections a second application may be necessary 2-3 weeks later.

Net Blotch (Pyrenophora teres)
Apply SiltraXpro at the first signs of disease in spring/early summer. For severe infections, a second application 2-3 weeks later will give most effective control when conditions remain favourable for disease development.

Ramularia (Ramularia collo-cygni)
Apply SiltraXpro at the first signs of disease. Applications made to established infections are likely to be less effective.

RESISTANCE STRATEGY
Tank-mixtures or alternation with fungicides having a different mode of action against the diseases present have been shown to protect against the development of resistant forms of disease.
No more than two applications of SDH inhibitors must be applied to the same cereal crop.

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