PHYTOSANITARY WARNING
08/05/2009
GRAPEVINE Phenological stage - Separated
cluster |
Mildew: |
We
detected the first spot in two different monitoring plots in O Salnés,
particularly in Castrelo and A Modia sites. In other areas, (different from O
Rosal and Tremoedo) first symptoms were not observed yet. In fact, adequate
optimum conditions for disease development did not take place so far, but next
week it is expected a change in the weather conditions that could favour spot
occurrence. If the grapevine is not already protected by a previous
treatment, it must be treated before precipitations take place, since
the plant is near the blooming stage, a period when the plant is more sensitive
to the disease.
|
Oidium: |
First
symptoms of the disease were not observed so far. It is not necessary to
treat yet.
|
Moths: |
The
number of moths captured has still been high, although the flight peak of the
first generation had already taken place and the number of captured males was
lower than in the previous week. Since symptoms were not observed so far,
plants must not be treated.
|
Mites: |
In spite
of the high temperatures recorded during these days, first colonies did not
appear yet. Acaricides should not be applied, unless the occurrence of
these arthropods is confirmed.
|
APPLE TREE |
Cydia
pomonella: |
The number of
insects collected per trap has reached the threshold of tolerance, thus
it is necessary to treat.
|
Aphids: |
The first
colonies of the green apple aphid were detected on shoots. The aphid
does not affect fruit development, thus it is not necessary to treat. However,
in some trees a large amount of rosy apple aphids that can cause fruit
deformation were observed. In this case, it is advised to apply an aphicide
(or, if we are using an insecticide against Cydia, we can apply a
product effective against both pests).
|
QUINCE TREE |
Oidium: |
First symptoms
of the disease were reported this week. Since they were widespread, it is
necessary to treat.
|
CAMELIA |
Chloropulvinaria floccifera: |
First colonies
of the insect are occurring in camellias planted all around the province.
An insecticide must be applied to avoid plant weakening and the
implementation of sooty mold in the honeydew secreted by the insect.
