Technical Open Field Day IRTA Lleida, 19th October 2016

The Open Day Technical Meeting (19th in Catalan language, 20th October in Spanish language) on fruit production is the most important meeting of fruit industry in Spain an also in the South of Europe accounting more than 1600 people in two days.
The most relevant results of the pest and diseases monitoring of the orchards belonging to the Fruit.Net program of Lleida (which includes peach, pear and apple species) were presented, which was followed by comments related to the incidence of 2016 fruit pests and diseases, the number of active ingredients detected in residues analysis and also the Fruit.Net control strategies to prevent fruit damages.
Regarding to the incidence of insects, an increase in the presence of peach twig borer (Anarsia lineatella) and Oriental fruit moth (Cydia molesta) has been observed in stone fruit. Results of residues of active ingredients on fruits highlighted that 79% of stone fruit samples reached tree or less active ingredients. On pear 75% of samples showed tree or less active ingredients compared with 68 % of the samples coming from the standard orchards, while on apple 68% of samples showed four or less active ingredients compared with 50 % of the samples coming from standard orchards
Concerning to the most prominent changes on defence strategies, it must be said that fluopyram was used in stone fruit preventive model to avoid Monilinia damages, instead of triazol’s fungicides and a strategy for the fire blight (Erwinia amylovora) control on pear.
