GRAPEVINE Phenological stage: Bunch closure- veraison (initial)
Mildew:Ver Fotos

In our monitoring plots we have only observed new symptoms of the disease on untreated control vines. At the veraison stage (so far we have only observed symptoms on some bunches in O Rosal and O Condado areas) the risk of bunch damage is low, but given the severity of the infections recorded along this summer and the environmental conditions registered, we must still be alert. Thus, we shall renew the treatments if symptoms are observed and/or in case the protection period of a previous treatment is about to conclude.

Oidium:Ver Fotos

We have only observed new symptoms of the disease occassionaly in those plants which have not been subjected to a treatment along the year.

Botrytis: Ver Fotos

We have not observed new affected berries, but the persistent warm and humid environmental conditions of these days, make it neccessary to monitor the plants and to improve the sanitary condition of grapevines so as to reduce any damage that could be caused by the pathogen.

Moths:Ver Fotos

Once again the number of captures in the traps has been low, and only sporadically eggs or larval penetrations have been registered. It is not necessary to treat.

Green mosquito and and cicadellidae:Ver Fotos

Cicadellids - Scaphoideus titanus femaleIf in previous phytosanitary warnings we reported an increase on the number of captures recorded in the traps placed in our monitoring plots, along this week insect populations have remained unchanged. On the other hand, we must pay special attention to the possibility of apparition of Scaphoideus titanus, at least in southern areas (where it has been previously detected), since in the last year, first adults were seen at this time of the season.

Mites:Ver Fotos

Calepitrimerus vitis - Bronzed leaves produced by rust miteCalepitrimerus vitis - In some grapevines located in O Salnés area we observed plants with symptoms of mite attack. Anyway, we must be aware that before treating plants, its presence and number should be confirmed, since the application of an acaricide could affect beneficial mites and favour the attack of phytophagous mites.

Scab:Ver Fotos

The risk of infection persists until the end of the year and, given the warm and humid conditions recorded, we recommend to keep plant monitoring and treat again in case new symptoms appear or if plants are not protected. In case plants are treated, we must pay attention to the withdrawal period of the selected funguicide, especially in those varieties that will be harvested soon.

Cydia pomonella:Ver Fotos

We have not recorded any capture in the pheromone traps placed in our monitoring plots. However, fruits must be checked in search of larval penetrations in the fruit.

Red spider:Ver Fotos

Panonychus ulmi femaleMobile stages of the mite on new shoots have been observed again in some areas. However, its incidence must be confirmed before treating.


Monilia sp symptoms on apple tree. Note fungal growth forming concentric rings. In those varieties being in the ripening stage, the fruits that have drop or fallen to the ground should be removed, since they are likely to be affected by monilia or botrytis under the present humid environmental conditions.

Proccesionary:Ver Fotos

Thaumetopoea pytiocampa (Processionary) - Processionary in feromone trap This lepidoptera continues its flight, since they were still captured in the traps placed in our monitoring plots.
