The presence in these days of fruiting bodies of #Armillaria, #HoneyMushrooms, in your orchard or garden is not a good sign. To prevent attacks of this parasitic fungi keep your trees in good health, avoid water stagnation and heavy pruning!

Impressive death of Norway spruce trees, Picea excelsa, caused by the #BarkBeetle #IpsTypographus in Val Badia, South Tyrol. Experts consider this massive attack a legacy of the storm Vaia, which knocked down 42,500 ha of woods in northern Italy in 2018. Increasing temperatures favored the beetle.

L'alternariosi del pomodoro, causata dal fungo patogeno #AlternariaSolani, ha un optimum di temperatura tra i 25 e i 35 gradi con elevata umidita'. Per questo si osserva facilmente adesso negli orti familiari. Efficaci distanza tra piante, trattamenti con rame e pulizia foglie.

Bamboo, if not properly contained and confined in gardens, can very easily become invasive occupying large areas, causing also problems with neighbours. Root barriers must be laid.

#OxythyreaFunesta, cetoniella, piccolo coleottero scarabeide che si nutre di polline e nettare, di fiori (in particolare bianchi) e foglie. Le sue popolazioni sono aumentate negli ultimi anni e possono causare danni. Nel giardino e nell'orto e' consigliata la raccolta manuale.
