PHYTOSANITARY WARNING

04/06/2009

VIÑA Phenological stage:		Condado and Rosal: fruit set
		Salnés and Soutomaior: blooming period (end)- fruit set
Mildew:
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:
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:
Symptoms 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:
Male 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:
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:
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.
APPLE TREE
Scab:
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:
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:
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.
