PHYTOSANITARY WARNING
15/05/2009
GRAPEVINE EPhenological stage: Inflorescences
separated, flowers separated. |
Mildew: |
As it was
expected in the previous phytosanitary warning, weather conditions in the last
days (rain and mild temperatures) favoured the apparition of oily spots,
already occurring in our monitoring plots. By now, inflorescences are highly
sensitive to the disease (although first symptoms have not been reported yet),
thus plants must be protected, using systemic or penetrating
fungicides so as they would not be washed by the rain (an hour without
precipitations must take place so as products would penetrate in the
plant).
|
Oidium: |
Symptoms
have not been observed yet. It is not necessary to treat.
|
Black-Rot:
|
In
our monitoring plot in O Condado, we have observed the first leaf with symptoms
of the disease, but so far it was only seen in a single
plant.
|
Moths: |
In almost
every area, the number of captures of first generation moths has been higher
than in previous years. However, no signs of larval activity were observed
yet. It is not necessary to treat.
|
Mites: |
As in
previous reports, mite populations were not observed either in our monitoring
plots or in the samples submitted to our laboratories. It is not
necessary to treat.
|
APPLE TREE |
Scab: |
Environmental conditions in the last days have favoured the
apparition of symptoms of the disease (especially on more sensitive varieties
such as Golden or Granny Smith), on the leaf, and also in a few fruits. In case
plants have not been previously treated, a fungicide must be
applied.
|
Cydia
pomonella: |
In our
monitoring plots, captures were lower than in previous weeks, although plants
have not been treated. However, they are still in the threshold of tolerance,
thus plants must be treated in case they had not been previously subjected to a
previous treatment.
|
Aphids: |
Colonies of the rosy apple and green apple aphids have still
been observed on the shoots. In fact, this year aphid populations are been
higher than in the past in some crops, thus it is advised to treat in
case leaves show the curling symptoms characteristic of the insect
attack.
|
CITRICS |
Aphids: |
First
aphid colonies belonging to different species are being observed on shoots of
lemon trees, orange trees and tangerine trees, causing leaves to curl. In this
case plants must be treated.
