PHYTOSANITARY WARNING

09/06/2009

SEVERAL CROPS
Damage by winds:

Winds recorded yesterday broke new shoots of some crops and even branches from trees belonging to several species. Branches are torn by the wind, and these wounds are a way of entry for several pathogens. Thus, it is advised to remove shoots and broken branches and apply a healing product (such as captan) as soon as rain stops.

Aphids:

Aphid colony on PopulusAphid colony on cherry treeWe are still observing colonies belonging to several aphid species in agricultural, ornamental and forestry crops. It is advised to treat whenever symptoms appear.



GRAPEVINE
Oidium :Ver Fotos

In the warning of July 4th we reported the appearance of the first symptoms of oidium. In case plants were previously treated with sulphur, this treatment could have been washed away by the rain, thus it must be applied again (a systemic fungicide antioidium can be also applied) as soon as weather become more stable.

WALNUT TREE
Anthracnose :Ver Fotos

We detected new symptoms of anthracnose on leaves, which have been favoured by the rainy weather occurring during these days. Even though treatments against the disease are more effective if applied from shoot development, it is advised to apply a mancozeb or miclobutanil based product at this stage.
