VIÑA Phenological stage: Condado and Rosal: fruit set
Salnés and Soutomaior: blooming period (end)- fruit set
Mildew:Ver Fotos

Plasmopara vitícola - Mildew symptom: Sporulation on leaf underside The current phenological stage of grapevine is very sensitive to mildew and the environmental conditions favour disease development. Thus, several spots with sporulation have been observed in control plots (untreated) and isolated spots were also detected in some of our monitoring plots, mainly in Castrelo (O Salnés area). It is advised to treat again in case new spots appear, even though the protection period of a previous treatment did not finish.

Oidium:Ver Fotos

Uncinula necator - First symptoms on leaf.As we have reported in a previous phytosanitary warning, first symptoms of the disease have been observed on leaf, mainly due to the misty weather of these days. It is necessary to treat..

Black-Rot: Ver Fotos

Black rot - Spot detail showing picnidiaSymptoms of this disease have been more important in O Condado area. Specific antimildew products are also registered for the control of black rot. Thus, a good strategy antimildew should also reduce damage caused by this disease.

Moths:Ver Fotos

The European grapevine moth- glomerulusMale captures recorded per trap ranged from 4 to 7 males in our monitoring plot. An increment was also observed in the number of glomerulus, however so far it is not necessary to treat.

Mites:Ver Fotos

Acariose first symptoms As it was expected, along this week we have observed the first populations of rust mites (Calepitrimerus vitis) but only on control plots belonging to O Condado area. Even though, acaricides should not be used, unless population occurrence or symptoms are confirmed.

Altica:Ver Fotos

L3 larvae feeding on leafL3 larvae feeding on fruit.Larval populations have reached a peak along this week in our monitoring plot in O Condado. Plants should be inspected for any sign of feeding activity.

Scab:Ver Fotos

Symptoms have been observed in untreated plants. Environmental conditions of these days are highly favourable for the pathogen, thus plants should be monitored and treated in case the characteristic spots of the disease appear.

Cydia pomonella:Ver Fotos

Male captures have been high in some traps. In case the crop protection period has finished, it must be renewed to avoid catterpillar entering the fruit.

Aphids:Ver Fotos

Rosy apple aphid - Colony on leaf underside This year aphid colonies are continuously occurring in fruit trees. New populations of the rosy apple aphid have been detected on apple tree shoots, therefore it is necessary to treat to avoid fruit deformation.
