GRAPEVINE Phenological stage: Grains pea sized
Mildew:Ver Fotos

Racimo en tamaño guisante con ataque de mildiuWe are still within the situation of extreme risk due to current climatic conditions. We are continuously registering favourable conditions for the infection to occur. In fact, mildew was observed on berries, in most plots in every area (Salnés, specially). With this situation, it is necessary to treat again, using a cupric and a penetrating fungicide, and apply again in case the disease does not cease. In addition, with the current environmental conditions and the index of associated risk, it is advised to carry out any practice that could favour berry ventilation, such as summer pruning or removing leaves.

Oidium:Ver Fotos

We haven't observed new symptoms, but monitoring should be maintained (or even treat), especially those grapevines moderately affected by mildew.

Black-Rot: Ver Fotos

Daños de black rot en racimoIn our monitoring plot in O condado we have observed the first symptoms in the berries. The disease was also detected in other plots in the area. In general, the pathogen can be controlled using anti-mildew fungicides, but in extremely severe cases, these treatments may not be totally effective. Sheet

Moths:Ver Fotos

The number of male moths captured in the traps was similar to those recorded in the previous week. Larval penetrations were not recorded. It is not necessary to treat.

Green mosquitoes and other cicadellidae:Ver Fotos

Cicadélidos - Ninfa de Emposaca vitis en envés de la hojaThe number of captures in the traps was higher, also the number of nymphs observed on the leaves. So far it is not necessary to treat, but monitoring should be increased.

Scab:Ver Fotos

First spots of apple scabHigh sensitive varieties show symptoms of the disease in some areas. If plants are not protected by a previous treatment (we must be aware that if contact fungicides were used, they could have been washed away by the rain), they should be treated.

Cydia pomonella:Ver Fotos

We have only captured a single specimen in one of the traps placed in our monitoring plot. However, we must check for symptoms of larval penetration into the fruit.

Red spider:Ver Fotos

Aspecto bronceado de las plantas por ataque de araña rojaWe are still observing visual symptoms of the attack of the mite in some plants. If a treatment is performed, its effect should be tested in case it is necessary to renew it to avoid a probable defoliation.


Moniliosis en cirueloMoniliosis en nectarinaWe are receiving samples of plum, peach, etc. with symptoms characteristic of the presence of Monilia, which has undoubtedly favoured fruit cracking due to rainfall. Apart from applying a fungicide (with products such as folpet or mancozeb), it is advised to remove damaged and fallen fruits.


Larvas de gusanos de alambreDetalle de daños de gusanos de alambre en planta de maizWe are still receiving samples of maize damaged by these soil larvae. Damages can be reduced, in case their presence is confirmed, spraying 25 and 48% clorpiriphos, active ingredient registered by the ministry to control these insects once they are established on the plants.
