PHYTOSANITARY WARNING

19/06/2009

GRAPEVINE Phenological stage: Fruit setting- Pea size
Mildew:Ver Fotos

The mist and night moisture of the last days favoured the appearance of certain oily spots on untreated plants and also the first symptoms of the disease on some berries. However, in our monitoring plots we haven't observed new symptoms, except for Tremoedo where, in spite of having treated plants on Thursday 11th, new spots are appearing. Thus, plants need to be monitored to check the evolution of the disease, in spite of being already protected by a previous application.

We haven't observed new symptoms, even in plants that were not treated during this year. However, at this stage grapes are highly sensitive to the disease, thus plants need to be monitored.

This week the maximum number of moths captured per trap was seven males (in most plots no captures were recorded). Now, we have to check berries for glomerulus appearance, although so far they were almost not present. It is not necessary to treat.

Almost no insects were captured in the sticky traps placed in the monitoring plots. It is not necessary to treat.





Mites:Ver Fotos

New mobile stages of the red spider Panonychus ulmi on samples from O Salnés area were observed. However, since mite density is still very low, it is not necessary to treat.

We have not observed new symptoms of the disease. However, since fruits could still be affected by this pathogen, plants need to be protected provided a specific surveillance programme is not followed.
