An oil-in-water emulsion containing 250 g/l (23.8% w/w) tebuconazole.
A broad-spectrum triazole fungicide for control of a range of diseases in numerous agricultural and horticultural crops.

Crops:
Winter and Spring Wheat, Barley, Rye and Oats, Oilseed Rape, Cabbages, Swedes, Turnips, Field Beans, Carrots, Horseradish, Parsnips, Leeks and Linseed.

Directions For Use:
Caution: Fungicide Resistance
RIZA is a triazole fungicide. It is advisable to alternate the use of RIZA with a fungicide with a different mode of action (e.g. a piperazine or morpholine fungicide) to avoid the build-up of resistant strains of disease. Disease control may be reduced if strains of a disease less sensitive to RIZA develop.
RIZA contains a DMI fungicide. Resistance to some DMI fungicides has been identified in Septoria leaf blotch (Mycosphaerella graminicola) which may seriously affect the performance of some products.
For further advice on resistance management in DMIs, contact your agronomist or specialist advisor and visit the Fungicide Resistance Action
Group (FRAG) U.K. website.

Mixing and Application:
Shake the container thoroughly before opening and use.
Half-fill the sprayer tank with clean water and begin agitation. Add the correct amount of RIZA using a filling device (e.g. an induction hopper) or by direct addition to the tank, followed by the rest of the water.
Rinse the container clean, preferably with an integrated pressure rinsing device, otherwise manually 3 times. Add the washings to the spray tank at the time of filling. Apply without delay. Maintain agitation while travelling and throughout the spraying operation.
Apply as a ‘Medium’ spray at a pressure of 2-3 bar. Do not apply in frosty weather. Apply to dry foliage.
Thoroughly clean the sprayer after use.
