In general, the trees were in good condition and seemed to have enough moisture. In some trees, however, there were the first signs of infestation by the insect “Euphyllura olivina” or, based on the Greek slang, simply “(olive tree) louse”. The louse forms colonies on the flower buds and, as a pupa, covers them with their sticky, white excrement, making heavily infested trees look like they are covered with cotton wool. This prevents pollination. In addition, the pupa feeds on the juices of the buds and affects the productivity of the tree. It is an annual phenomenon in April – May, but its extent varies and depends on various conditions, primarily the weather.
Luckily, the louse is easily controlled with a solution of water and hand soap sprayed liberally on the trees!
Otherwise, no diseases or enemies were discovered. The biggest concern, especially now that summer is approaching, is the weather. It is important that it rains a little every now and then and that there is not a heat wave, as happened in May last year, while the trees are still in bloom.
