((1) Application of OSIRIS P to ears of wheat and triticale can lead to reduction of the levels of the mycotoxin deoxynivalenol (DON) associated with Fusarium ear blight infection, but this level of effect may not necessarily lead to reduction of DON below the statutory limit in wheat and triticale grain. # When applied at 2 litres per hectare OSIRIS P will achieve Moderate Control of Fusarium ear blight. OSIRIS P can also be used at 1.33 litres per hectare for Good Reduction of this disease. C = Control GR = Good reduction MC = Moderate control R = Reduction)
 
Resistance management
Strains of certain diseases with decreased sensitivity to triazole fungicides are known to exist in the UK. Where these occur or develop, OSIRIS P may not give satisfactory control.
OSIRIS P contains the DMI fungicides epoxiconazole and metconazole. 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 with DMIs contact your agronomist or specialist advisor, and visit the FRAG-UK website.
A strategy for managing resistance should be adopted. Guidelines have been produced by the Fungicide Resistance Action Committee (FRAC) and copies are available from HGCA, CPA, your distributor, crop adviser or product manufacturer.
 
Crop specific information
Crops
OSIRIS P may be used on all varieties of winter and spring wheat, durum wheat, winter and spring barley, rye and triticale.
Time of application
Apply OSIRIS P at the start of disease attack. Applications in wheat, rye and triticale can be made up to the end of flowering (GS 69). Applications in barley can be made up to the end of ear emergence (GS 59).
For optimum effect against eyespot with OSIRIS P apply between the leaf sheaths erect and second node detectable stages of the crop.
For protection against Fusarium ear blight and sooty moulds on the ears of winter and spring wheat, durum wheat and triticale, apply OSIRIS P during ear emergence.
Rate of application
Apply 2 litres of OSIRIS P in 150 to 300 litres of water per hectare.
Osiris P may be applied at 2 litres per hectare in 100 litres water per hectare although efficacy at this reduced volume has not been evaluated. Therefore application at 100 litres water per hectare is at user’s risk with regard to biological efficacy.
Reducing the water volume is not recommended where control of stem base diseases is required.
When applied at 2 litres per hectare OSIRIS P will achieve Moderate Control of Fusarium ear blight. OSIRIS P can also be used at 1.33 litres per hectare for Good Reduction of this disease.
 
Following crops
After treating a cereal crop with OSIRIS P, oilseed rape, cereals, sugar beet, linseed, maize, clover, beans, peas, carrots, potatoes, lettuce, cabbage, sunflower, ryegrass and onions may be sown as the following crop. The effect of OSIRIS P on other crops has not been assessed.
Mixing and Spraying
Mixing
Never prepare more spray solution than is required.
Fill the tank half full with water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of OSIRIS P to the spray tank while re-circulating. Fill up the tank with water and continue agitation until spraying is completed.
On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely.
Application
Apply as a MEDIUM spray as defined by BCPC.
Sprayer cleaning
After spraying, thoroughly clean and flush out application machinery with a minimum of three rinses.
