Protect young plants through autumn
Young plants, or vines newly grafted this season should be protected through the autumn period—particularly those located in frost-prone sites or close to Psa-V affected locations.
New leaf spot symptoms are being seen on a number of sites indicating a lift in Psa-V activity as we begin to experience colder wetter weather periods.
A protective spray programme re-establishing copper cover is now high priority to protect young tissue and plants.
The KVH Psa-V Risk Model has predicted high risk periods for Psa-V over the last few weeks with these periods matching periods of rainfall.
