For use only as an agricultural fungicide for the control of stem-base, foliar and ear disease in winter and spring wheat (also reduction of the mycotoxin deoxynivalenol), durum wheat, triticale, winter rye, winter and spring barley, winter and spring oats and for disease control in winter oilseed rape.

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.

GENERAL INFORMATION

PROTENDO 250 EC is a triazolinthione fungicide recommended for control of a wide range of diseases on winter and spring barley, winter and spring wheat, durum wheat, triticale, winter rye, winter and spring oats, and for disease control in winter oilseed rape.

RESISTANCE STRATEGY

Repeated application of PROTENDO 250 EC 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 (e.g. morpholines) have been shown to protect
against the development of resistant forms of disease.
Take all precautionary measures to reduce the selection pressure for insensitive Septoria tritici strains (e.g. tank-mix with product having a different mode of action which is active against Septoria). Consult your advisor for up to date guidance regarding current resistance status and a strategy for preventing and managing resistance in the cereal and oilseed rape pathogens listed on the label.
The Fungicide Resistance Action Committee (FRAC) produces recommendations that may be consulted for additional information.
Strains of light leaf spot resistant to azole fungicides are known to exist. To avoid development of resistance apply product protectively in response to disease forecasts. Where possible,
when light leaf spot is present, avoid the use of azole based fungicides when targeting other diseases such as Sclerotinia at mid flowering stage.
Caution: The possible development of disease strains resistant to PROTENDO 250 EC cannot be excluded or predicted. Where such resistant strains occur, PROTENDO 250 EC is unlikely to give satisfactory control.

CROP SPECIFIC INFORMATION

PROTENDO 250 EC may be used on all commercial varieties of winter and spring barley, winter and spring wheat, durum wheat, triticale, winter rye, winter and spring oats and winter oilseed rape.

Cereals
Method of application: Tractor mounted/trailed sprayer.
Apply PROTENDO 250 EC at 0.8 L/ha in 100-300 L water/ha.
Apply as a MEDIUM spray quality. A spray pressure of 2-3 bar is recommended. Maximum total dose per crop is 1.6 L/ha for barley and oats and 2.4 L/ha for wheat and rye. PROTENDO 250 EC may be applied at any stage before grain milky ripe stage (GS 71) in winter wheat and winter rye and up to beginning of flowering in barley and oats (GS 61).

Winter Oilseed Rape
Method of application: Tractor mounted/trailed sprayer.
Apply PROTENDO 250 EC at 0.7 L/ha in 100-300 L water/ha.
Apply as a MEDIUM spray quality. A spray pressure of 2-3 bar is recommended. Maximum total dose per crop is 1.4 L/ha. PROTENDO 250 EC may be applied at any stage before beginning of side shoot development (GS 21).
Apply PROTENDO 250 EC in 100 to 300 litres of 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.
