Verticillium Wilt Not just a European disease…..

An increasing problem in the UK!

Dr Gladders’ recommendations for managing the risk were

1. Determine its prevalence on individual farms

2. Good agronomy – a strong plant holds off verticillium

3. Extended rotations

4. Variety choice

Trinity has good resistance –

1. Galileo parent has very good resistance

2. Trinity performed excellently in the Gottingen trials.
