Particle Film Technology: approach for a biorational control of Cacopsylla pyri (Rhynchota Psyllidae) in Northern Italy
Bulletin of Insectology 55 (1), 39-42
Abstract: Two trials were carried out to investigate the efficacy of a kaolin-based product (Surround WP) a white non-abrasive, fine-grained alluminum-silicate mineral in controlling pear psylla Cacopsylla pyri (L.) oviposition. The trial was carried out in Italy's Emilia-Romagna Region on cv. Abbè Fétel during late winter in 2001-2002 year; the reference product was mineral oil. The timing of product application was before or at the onset of egg laying during overwintering. The results show a very good efficacy of kaolin in comparison to the mineral oil and untreated control. No eggs were found on the treated plants and no phytotoxic effects were observed. No nymphs were observed inside the flowers in the kaolin-treated plots.
