Resistance management
Apply Cloister according to the instructions for the target diseases at the specific growth stage indicated.
Apply a maximum of two sprays of Cloister per crop.
Cloister should be used as part of a resistance management strategy that includes use in mixtures or sequences that are effective against mildew as well as non-chemical methods e.g. cultural control. Cloister contains metrafenone which is a benzophenone fungicide. Do not apply more than two applications in total of products containing either benozophenones or benzoylpyridines to any one crop. Do not mix with products containing pyriofenone. Avoid using sequential applications of products containing metrafenone.
To reduce the risk of resistance development, where mildew is established at the time of application, Cloister should be used in mix with a mildewicide with an alternative mode of action e.g. fenpropimorph (Corbel).
Strains of certain diseases with decreased sensitivity to triazole fungicides are known to exist in the UK. Where these occur or develop, Cloister may not give satisfactory control.
Cloister 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 FRAG-UK website.
 
Crop specific information
Crops
Cloister can be used on all varieties of winter wheat, durum wheat, spring wheat, winter barley, spring barley, oats, rye and triticale.
Time of application
Apply Cloister at the start of foliar disease attack. A maximum of two applications can be made up to the beginning of flowering (GS61) in winter and spring wheat, durum wheat, rye and triticale and up to and including emergence of ear just complete (GS59) in winter and spring barley and oats.
For protection against Fusarium ear blight and sooty moulds (Cladosporium, Botrytis) on the ears of winter and spring wheat and durum wheat apply Cloister during ear emergence.
Rate of application
Apply 1.5 litres Cloister in 200 to 400 litres of water per hectare.
Qualified recommendation
If required, water volumes down to 100 litres per hectare may be used, however these have not been supported by effectiveness or crop safety data.
 
Following crops
After treating a cereal crop with Cloister, cereals, oilseed rape, sugar beet, linseed, maize, clover, field beans, peas, turnips, carrots, cauliflower, onions, lettuce and potatoes can be planted as succeeding crops.
 
Mixing and Application
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 Cloister to the spray tank while re-circulating. Fill up the tank with water and continue agitation until spraying is completed.
When tank mixes are to be used, take due note of any instructions given as to the order of mixing. Each product should be added separately to the spray tank and fully dispersed before the addition of any further product(s).
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.
The following does not form part of the product label under the Plant Protection Products Regulations 2005.
With many products there is a general risk of resistance developing to the active ingredients. For this reason a change in activity cannot be ruled out. It is generally impossible to predict with certainty how resistance may develop because there are so many crop and use connected ways of influencing this. We therefore have to exclude liability for damage or loss attributable to any such resistance that may develop.
To help minimise any loss in activity the BASF recommended rate should in all events be adhered to.
