Abstract
This study aimed to evaluate the influence of soil management on the occurrence of pests and natural enemies in the rose cultivation under Integrated Production System.
The experiment was carried out at the Agricultural Research Enterprise of the State of Minas Gerais, in São João del Rei-MG, Brazil. Carolla rose graftings were used.
The experimental design was in randomized blocks with 8 treatments composed of 4 chemical fertilization percentages (25, 50, 75 and 100%) versus presence and absence of combination with green manure (Calopogonium mucunoides) and four replications each.
Samplings of phytophagous arthropods and natural enemies were carried out weekly, from February to November 2010. The occurrence of mites, aphids, whitefly, beetles, parasitoids and predators was observed.
In the area with presence of green manure, lower number of aphids (3.9±0.58 aphids/leaflet) and mites (1.2±0.44 mites/leaflet) was observed, when compared to area without green manure (6.7±0.56 aphids/leaflet and 2.4±0.69 mites/leaflet). In all treatments, high-quality flower stalks with long stems (average length of 50-100 cm) were obtained.
It was concluded that the soil management directly influences the occurrence of pests and natural enemies in the rose cultivation in integrated production system.
