For use as an agricultural fungicide for the control of stembase, foliar and ear diseases in winter and spring wheat (also reduction of the mycotoxin deoxynivalenol), winter rye and triticale.

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.
Croton is a mixture of a triazolinthione and triazole fungicide recommended for control of a wide range of diseases on winter and spring wheat, triticale and winter rye.

Eyespot (Oculimacula spp.)
Croton 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 Blotch and Glume Blotch (Mycosphaerella graminicola and Stagonospora nodorum)
Apply before disease is established in the crop. To protect the upper leaves and ear apply Croton 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 (Blumeria graminis)
Apply Croton at the first signs of disease. Where disease pressure remains high application may be repeated.
Yellow Rust and Brown Rust
Apply Croton at the first signs of disease. A second application may be made 2-3 weeks later if reinfection occurs. Applications made to established infections are likely to be less effective.
Tan Spot (Pyrenophora tritici-repentis)
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 (GS 59-69) for control of
Fusarium Ear Blight and reduction of Sooty Moulds. Control of ear diseases can result in cleaner, brighter ears.
Through the reduction of ear blight, Prosaro effectively reduces the level of the Fusarium mycotoxin deoxynivalenol (DON) in wheat grain. However, where Fusarium levels are high, the reduction achieved may not always be sufficient to ensure that DON levels fall below the statutory limit.
Leaf Blotch (Rhynchosporium secalis)
Croton gives high levels of Rhynchosporium control. Apply Croton in spring at the first signs of disease. For severe infections a second application may be necessary 2-3 weeks later.

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
