Indagini sulla presenza di Prays oleae in oliveti a conduzione biologica della Sicilia occidentale
2011
Investigations on presence of Prays oleae in organic olive orchards of western Sicily. This paper reports a study on the population dynamics of the olive moth, Prays oleae (Bern) (Lep., Plutellidae) in four organic olive orchards in western Sicily (Italy), from 2007 to 2010. The influence of the phytophagous on the fruit drop was detected. Also, the efficacy of treatments with Bacillus thuringiensis var. kurstaki on damage reduction was evaluated. Flight trend was monitored using delta-wing traps (3/ha) containing the sexual pheromone ((Z)-7-tetradecenal), placed in each olive orchard. Traps were hung in the inner zone of the canopy to a height of 1.50 m, and checked weekly from May to 2-3 …
Foliar fertilization in ‘Nocellara del Belice’ olive trees
2008
Eight-year-old olive trees of ‘Nocellara del Belice’ grown in central Sicily were treated with five different types/combinations of organic and mineral foliar fertilizers. Floral 20-20-20 (mineral N, P, K, and microelements; FLO), Alga (extract of brown algae; ALG), FLO+ALG, Azomin (organic N, amino acids and peptides; AZO), Supernat93 (organic N and K, distillation residue; SUP), and water (CONTROL) were applied four times during summer and fall 2002. Yield and trunk circumference were measured during fall 2002, whereas other vegetative and reproductive parameters were measured during spring-fall 2003. AZO and SUP trees produced more than CONTROL and ALG ones, whereas only AZO trees showed…
