Summary in the original language of the document
Neste estudo foram avaliados diferentes embalagens e métodos de ensacamento sobre a incidência de pragas e doenças, bem como a qualidade de frutos até a colheita. O experimento foi realizado a campo, em dois períodos, com a cultivar Douradão sob sistema orgânico de produção. Em 2004, os tratamentos foram: saco de papel pardo 11,5 cm x 15,0 cm, saco de papel manteiga (parafinado) 11,0 cm x 16,0 cm e sem ensacamento. Em 2007 os tratamentos foram: saco de papel manteiga (parafinado) fechado com grampo; o mesmo saco fechado com arame plastificado (8,0 cm de comprimento) e sem ensacamento. Os frutos foram ensacados na fase de raleio (2 cm Ø) e avaliados na fase de colheita. As embalagens de papel pardo e papel manteiga foram eficientes na prevenção da incidência de mosca-das-frutas e diminuíram a incidência de podridão parda em frutos. O sistema de fechamento das embalagens com grampo ou arame não diferiu quanto incidência de pragas e doenças e qualidade dos frutos, porém com grampo a operação de ensacamento foi mais rápida.
Summary translation
In this study we evaluated the efficiency of different methods of bagging to prevent the incidence of pests and disease and the quality evaluated of bagged fruit to harvest. The experiment was carried out in the field, in two periods with Douradão cultivar, in the organic crop system. In 2004, treatments were: brown paper bag 11.5 cm x 15.0 cm, paraffin paper bag 11.0 cm x 16.0 cm and control of non-bagging. In 2007 the treatments were: paraffin paper bag closed with clip, paraffin paper bag closed with plastic wire (8.0 cm) long and control of non-bagging. Fruits were bagged during the thinning (2 cm Ø) and evaluated during the harvest. The packaging of brown paper and paraffin paper were efficient in preventing the incidence of fly-fruit and reduced the incidence of brown rot on fruit. The closure system of packaging with clip or plastic wire were similar in the prevention of pests and diseases and fruit quality, but with clip the bagging were more rapid.
