GRAPEVINE Phenological stage: flowers separated
Mildew:Ver Fotos

Along this week we did not observe new symptoms of the disease in our monitoring plots. In fact, this year the level of damage caused by the pathogen has been low, and even in neglected and abandoned grapevines it is hard to find a spot. Anyway, grapevines should be intensively monitored given the environmental conditions occurring during these days and since in this stage inflorescences are highly sensitive to the disease.

Oidium:Ver Fotos

Symptoms were not observed so far. It is not necessary to treat, but an eye must be kept on the plants, since climatic conditions occurring during these days favor the development of the pathogen (mild temperatures, locally persistent mist, and high moisture).

Moths:Ver Fotos

During these days moths captured did not follow a constant pattern: whereas some plots registered more moths, in others the number of moths collected decreased. We did not observe any signs of larval activity. It is not neccesary to treat.

Mites:Ver Fotos

So far neither mites nor symptoms were observed. It is not necessary to treat.

Altica:Ver Fotos

Hoja de Albariño con ataque de AlticaHuevos eclosionados y larva de AlticaIn a previous phytosanitary warning we have reported the presence of Altica quercetorum in our monitoring plot in O Condado. In this week we have observed new symptoms and an increase in the area affected by the crisomellyd. Plants need to be inspected to check for symptoms.

Apple scab:Ver Fotos

Damage of apple scab on apple fruitThe treatments applied following the recommendations of the previous phytosanitary warning have restrained the evolution of the disease. Anyway, plants should be monitored since conditions are still favorable for the development of the pathogen and fruit development could be affected.

Oidium:Ver Fotos

Podosphaera leucotricha - Apple shoot with oidium symptomsWe have observed new shoots with oidium, which was favoured by the current environmental conditions. It is necessary to treat.

Cydia pomonella:Ver Fotos

The captures of the codling moth in our monitoring plots did not reach the threshold of tolerance.

Aphids:Ver Fotos

Eriosoma lanigerum - Wooly aphid parasitedWooly aphid colonies on apple treeAs it was recommended, the applications performed have eradicated the rosy apple aphid colonies, and prevented the occurrence of new ones. From now on, we must choose innocuous insecticides for the beneficial organisms since Eriosoma lanigerum, the parasitoid of the wooly apple aphid, has clearly become active and presents large populations in this year.
