WINTER OILSEED RAPE

Rate: 1.0L/ha
Critical comments: Maximum total dose per season 2.0 litres product per hectare per season. Latest time of application: up to a pre harvest interval of 56 days.
Eyespot (Tapesia spp.)
Prosaro reduces the incidence and severity of Eyespot. 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).
Septoria Leaf Spot and Glume Blotch (Septoria tritici and Leptosphaeria nodorum)
Apply before disease is established in the crop. To protect the upper leaves and ear apply Prosaro at full flag leaf emergence (GS 37) up to mid-flowering (GS 65). Where disease pressure remains high application may be repeated.
Applications to upper leaves where S. tritici symptoms are present are likely to be less
effective.
Powdery Mildew (Erisiphe graminis)
Apply Prosaro at the first signs of disease. Where disease pressure remains high application may be repeated.
Yellow Rust
Apply Prosaro at the first signs of disease. Prosaro controls Yellow Rust (Puccinia striiformis) in wheat. A second application may be made 2-3 weeks later if re-infection occurs. Applications made to established in fections are likely to be less effective.
Brown Rust
Apply Proasaro at the first signs of disease. Prosaro controls Brown Rust in barley (Puccinia hordei), rye (P. recondita) and wheat (P. recondita). 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.
Tan Spot (Pyrenophora tritici-repensis)
Apply Prosaro at the first signs of disease in spring/early summer. Apply Prosaro at the first signs of disease in spring or early summer. Where disease pressure remains high application may be repeated.
Ear Disease Complex
Apply Prosaro soon after ear emergence until the end of flowering (GS59-69) for control of Fusarium Ear Blight and reduction of Sooty Moulds. Control of ear diseases can result in cleaner, brighter ears.
Leaf Blotch (Rhynchosporium secalis)
Prosaro gives high levels of Rhynchosporium control. Apply Prosaro 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 Prosaro 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.
RESISTANCE STRATEGY
Repeated application of Prosaro alone should not be used on the same crop against a high risk pathogen such as cereal powdery mildew. Tank mixtures or alternation with fungicides having a different mode of action (eg morpholines) have been shown to protect against the development of resistant forms of disease.
CAUTION:
The possible development of disease strains resistant to Prosaro cannot be excluded or predicted. Where such resistant strains occur, Prosaro is unlikely to give satisfactory control.
CROP SPECIFIC INFORMATION
Prosaro may be used on all commercial varieties of winter and spring barley, winter wheat and winter rye.
Apply as a medium spray quality. A spray pressure of 2-3 bar is recommended.
Apply Prosaro in 200-300 litres per hectare water.
Mixing
Thoroughly shake the pack before use.
Add the required quantity of Prosaro 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 before 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.
