PHYTOSANITARY WARNING
23/07/2009
GRAPEVINE Phenological stage: bunch
closure |
Mildew: |
The unstable
conditions recorded will make it necessary to treat whenever
precipitations stop to avoid any damage to the bunch. Although the
grapevine is protected by a previous treatment, we must be aware that
precipitations occurring have been enough to wash away any contact
fungicide and to reduce the effect of penetrating fungicides. In
addition, due to the high environmental moisture, we recommend to
eliminate the vegetation excess around bunches, removing leaves
and prune if shoots impede grape aeration.
|
Oidium: |
The risk of attack of
this pathogen to the bunch is not high.
|
Botrytis:
|
Along this week
we have observed the first berries affected by botrytis. As we have reported in
the previous phytosanitary warning, the fungus has established in the skin
cracks as a consequence of the severe mildew outbreak observed in the last
week, favoured by the climatic conditions (heat and high humidity). It is
necessary to treat, focusing the applications on bunches.
|
Moths: |
The number of
captures in the traps has still been low. Eggs and larval penetrations are
occasionally observed. It is not necessary to treat.
|
Green mosquito and
other cicadellidae: |
Once again the number
of Zygina rhamni and Empoasca vitis captures recorded in the
traps has been high. However, it is not necessary to treat.
|
Mites: |
We have not observed
any symptoms of mite attack or populations in leaf surveys. It is not necessary
to treat.
|
Wood diseases: |
We should mark
those plants with symptoms of any wood disease to differentiate them from the
rest when carrying out opportune measures.
|
APPLE
TREE |
Scab: |
Although new symptoms have not
been reported yet, whenever precipitations stop, treatments should be renewed
to protect developing fruits.
|
Cydia
pomonella: |
We did
not have captures in the pheromone traps placed in our monitoring plots.
Anyway, plants should be checked to search for any sign of larval penetrations
in the fruits.
|
Red
spider: |
Environmental conditions were not favorable for mite
development
|
OAK |
Altica
quercetorum: |
According to
the information given, signs of attack of this defoliator have been observed.
We must be aware that the only chemicals recommended by the Ministry for the
control of these insects on oak are deltamethrin (controlling both adults and
larvae) and flufenoxuron (against larvae).
|
PINE |
Processionary: |
On the basis of the captures registered in the traps placed on
pine trees, we know that the Lepidoptera has initiated its flight (maximum
number of captures: nine males).
