GRAPEVINE Phenological stage: Setting
Mildew:Ver Fotos

Plasmopara vitícola - Initial symptoms on leaf The risk of secondary infection after the environmental conditions occurring in the last days has been high, and in fact new oily spots have appear in untreated control plots. Weather forecast announces quite stable weather for next week. Due to the high sensitivity of grapevine it is advised to increase monitoring, and treat whenever new symptoms appear.

Oidium:Ver Fotos

Uncinula necator - First symptoms on leafWith the constant and relatively strong precipitations of these days, oidium did not increase. However, at present grapevine is highly sensitive to the disease, thus it is necessary to perform a high surveillance of the grapevines.

Botrytis:Ver Fotos

Precipitations of these days occurring at the end of the blooming period have caused that many flower caps adhere to the berries and did not separate. Botrytis can occur in moist conditions, thus at least in very sensitive varieties (Treixadura, Godello..) it is advised to apply a preventive treatment mainly directed to berries.

Moths:Ver Fotos

Along this week almost no captures have been recorded in the pheromone traps. It is not necessary to treat.

Panonychus ulmi femaleAlong this week we have detected the first mobile stages of the red spider Panonychus ulmi on samples submitted to our laboratory taken in O Salnés area. So far, mites were only found on 2% of the leaves, thus it is not necessary to treat, however the increase of temperatures could favour mite populations.

Apple scab:Ver Fotos

Environmental conditions of these days have favoured infections caused by this fungus. It is advised to protect plants against this mite to avoid damage to the fruit.

Oidium :Ver Fotos

Symptoms of the pathogen have been observed again in terminal shoots. However, its presence is limited to some plantations.

Cydia pomonella:Ver Fotos

We have only captured a single adult in the pheromone traps placed in our monitoring plots. In general, it is not necessary to treat. In case specific monitoring is not performed, it is advised to keep the plants protected, since certain variability among areas may take place.

Pammene fasciana:Ver Fotos

Pammene fasciana - Adult in pheromone trapWe have recorded the first captures of this chestnut pest in our pheromone traps.
