Treatment: Cut out and burn badly spotted canes. Spray raspberries with 5 percent lime sulphur at bud burst and 2,5 percent lime sulphur immediately before blossom time. Alternatively, use copper or thiram (except on fruit to be to be processed) at these times, or use benomyl or thiophanate-methyl from bud burst to the end of blossoming at fourteen day intervals.
