Resistance management
Apply Stiletto according to the instructions for the target diseases at the specific growth stage indicated. Apply a maximum of two sprays of Stiletto per crop.
Stiletto 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.
To reduce the risk of resistance development, where mildew is well established at the time of application, Stiletto should be used in mix with 350 g/ha fenpropimorph e.g. Corbel.
Stiletto 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 adviser, and visit the FRAG-UK website.
 
Crop specific information
Crops
Stiletto can be used on all varieties of winter wheat, spring wheat, winter barley, spring barley, oats, rye and triticale.
Time of application
Apply Stiletto 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, rye and triticale and up to and including emergence of ear just complete (GS59) in winter and spring barley and oats.
For optimum effect against eyespot apply between the leaf sheaths erect and second node detectable stages of the crop (GS30-32).
For protection against Fusarium ear blight and sooty moulds (Cladosporium, Botrytis) on the ears of winter and spring wheat, apply Stiletto during ear emergence.
For the control of Septoria tritici and Septoria nodorum , treatment should normally be made after third node detectable stage when disease is present and when weather favouring disease development has occurred. A follow up treatment may be necessary if conditions continue to favour disease development.
Rate of application
Apply 2.0 litres Stiletto in a minimum of 200 litres of water per hectare.
 
Following crops
After treating a cereal crop with Stiletto, 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 Stiletto 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.
