APPLES and PEARS
SYSTHANE 20EW is a systemic fungicide with protectant and curative activity against apple scab (Venturia inaequalis), apple powdery mildew  (Podosphaera  leucotricha)  and pear scab (Venturia   pirina).
SYSTHANE 20EW is most effective when used as part of a routine preventative spray programme from bud burst to the onset of peta l fall. SYSTHANE 20EW is safe to use during flowering. From the onset of petal fall SYSTHANE 20EW should be tank-mixed with protectant fungicides to enhance fruit scab control. From mid June, SYSTHANE 20EW can be applied alone for the control  of  secondary mildew.
SYSTHANE 20EW and SYSTHANE 20EW + Karamate Dry Flo Neotec mixtures are safe to use on all the main commercial varieties of apples and pears. Please consult the PP Captan 80 WG or Dithianon Flowable labels for details of varietal   restrictions.
 
SPRAY TIMING AND RATES OF USE
To control leaf scab and reduce the development of powdery mildew from primary infections, apply SYSTHANE 20EW from bud burst to the onset of petal fall at the following rates and spray intervals. To improve control of fruit scab after the onset of petal fall tank mix SYSTHANE 20EW with Karamate Dry Flo Neotec (UK only), Dithianon Flowable or PP Captan 80 WG (UK only). Tank mixtures should only be applied within the label recommendations of every product in the  mixture. 
If spraying intervals have been unavoidably extended, the next spray should be at the 11-14 day rate(s) to maximise the curative activity of SYSTHANE 20EW.
In periods of rapid growth or high disease pressure, SYSTHANE 20EW should be used in a programme at 7 day  intervals.
 
BLACKCURRANTS, GOOSEBERRIES AND STRAWBERRIES
BLACKCURRANTS  AND  GOOSEBERRIES
SYSTHANE 20EW controls American powdery   mildew.
SYSTHANE 20EW is most effective when used as part of a routine preventative spray programme from just before the first signs of       mildew infection up to two weeks before picking if necessary. Post-harvest treatments may be applied to reduce over-wintering inoculum.
 
STRAWBERRIES
SYSTHANE 20EW controls strawberry powdery   mildew.
SYSTHANE 20EW should be applied pre-harvest, beginning at or just prior to first flower and thereafter at the recommended spray intervals up to 3 days before picking. Post-harvest sprays may be required where mildew is present and likely to be damaging (especially mildew susceptible varieties).
This will help to produce vigorous growth and reduce the amount of over-wintering   inoculum.
