PHYTOSANITARY WARNING

08/04/2009

GRAPEVINE
Grapevine mildew:
In the two weeks we have monitored the plots included in our network, we haven't observed any phytosanitary incidence.

Plants have developed enough to be primarily affected by mildew, but night tempearures are too low for pathogen development. However, since first spots of the disease are likely to appear during these days, we must be alert in case temperatures rise.

At present the incidence of other pests and diseases is low

APPLE TREE
Powdery mildew and apple scab:

We have only observed some shoots with powdery mildew (a treatment is not necessary to be performed yet). Regarding apple scab, the same weather conditions (low temperatures) that hinder the development of the grapevine mildew are also negative for this pathogen.
