PHYTOSANITARY WARNING
02/07/2009
GRAPEVINE Phenological stage: Grains pea
sized |
Mildew: |
We 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: |
We haven't observed
new symptoms, but monitoring should be maintained (or even treat), especially
those grapevines moderately affected by mildew.
|
Black-Rot:
|
In 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: |
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: |
The 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.
|
APPLE
TREE |
Scab: |
High 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: |
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: |
We 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.
|
STONE FRUITS |
Moniliosis: |
We 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.
|
MAIZE |
Wireworms: |
We 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.
