Resumo
Objetivou-se, no trabalho, buscar opções ao ensacamento de pêssegos, visando o controle eficiente das principais pragas do pessegueiro. Para isso, instalou-se um experimento em um pomar comercial de pêssego do cultivar Aurora 2, conduzido em sistema de vaso e espaçamento de 6 x 4 m. Os tratamentos foram os seguintes: T1 - Sacolas de TNT branco (45 g/m²) fechado, T2 - Sacolas de TNT branco (45 g/m²) aberto, T3 - Sacolas de TNT branco (20 g/m²) fechado; T4 - Sacolas de TNT branco (20 g/m²) aberto; T5 - Sacolas de polipropileno microperfurado transparente (furos de 1mm) fechado; T6 - Sacolas de polipropileno microperfurado transparente (furos de 1mm) aberto; T7 - Sacolas de polipropileno microperfurado transparente (furos de 2mm) fechado; T8 - Sacolas de polipropileno microperfurado transparente (furos de 2mm) aberto; T9 - Sacolas de polietileno microperfurado leitoso (furos de 1mm) fechado; T10 - Sacolas de polietileno microperfurado leitoso (furos de 1mm) aberto; T11 - Sacolas de polietileno microperfurado leitoso (furos de 2mm) fechado; T12 - Sacolas de polietileno microperfurado leitoso (furos de 2mm) aberto; T13 - Sacolas de papel impermeável fechado; T14 - Sacolas de papel impermeável aberto; T15 - Testemunha (sem ensacamento). de acordo com os resultados concluiu-se que todas as embalagens foram eficientes no controle de moscas-das-frutas e pássaros, porém não para mariposa oriental. As sacolas com abertura no fundo podem ser utilizadas como opção ao ensacamento de pêssegos.
Aiming to look for new options of peach bagging in the control of peach insect pests, an experiment was carried out in a treeyear-old peach crop. The cultivar Aurora 2 was accomplished in vase system with 6 m among rows and 4 m among plants. The treatments were: T1 - white and closed TNT (tissue non-tissue) bag (45g/m²), T2 - white and opened TNT bag (45g/m²), T3 - white and closed TNT bag (20g/m²), T4 - white and opened TNT bag (20g/m²), T5 - transparent polypropelene microperfurated and closed bag (1mm of diameter), T6 - transparent polypropelene microperfurated and opened bag (1mm of diameter), T7 - transparent polypropelene microperfurated and closed bags (2mm of diameter), T8 - transparent polypropelene microperfurated and opened bag (2mm of diameter), T9 - milky microperfurated polyetilene and closed bag (1mm of diameter), T10 - milky microperfurated polyetilene and opened bag (1mm of diameter), T11 - milky microperfurated polyetilene and closed bag (2mm of diameter), T12 - milky microperfurated polyetilene and opened bags (2mm of diameter), T13 - closed and waterproof paper bag, T14 - opened and waterproof paper bag, T15 - check treatment (unbagging fruits). According to the results, it may be concluded that all bags are efficient to control fruit flies and birds, but not the oriental fruit moth. The opened bags may be used in peach bagging.
