Influência do tipo de ensacamento no controle de pragas do pessegueiro

Abstract

This research aimed to look for alternative bags that could offer protection against fruit-flies and oriental moth attack, offer easy procedure at the harvesting time of peach crops and verify two aspects referred to the bags: the practicability and the cost. The work was conducted at Santa Maria Farm in São Luis do Paraitinga County (São Paulo State), from August to November of 2006, in a tree-year-old peach crop. The cultivar Aurora 2 was conducted in modern vase system with 6m between rows and 4 m between plants. The experimental design followed randomized block, where each plant was considered one block. There were 15 treatments, 8 replications (blocks) and 10 fruits per treatment. 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). The results showed that bagging did not influenced chemical fruits characteristics, such as, pH, soluble solid contents (SS), titratable acidity (TA), SS/TA ratio, however, produced reasonable bigger and havier fruits. The fruit epiderm color was influenced by baging... (Complete abstract click electronic access below)

O presente trabalho teve por objetivos buscar alternativas às tradicionais sacolas de papel manteiga, buscando proteção segura aos ataques de insetos-praga e pássaros, maior facilidade no momento da colheita de pêssegos, e verificando também o custo e a praticidade das embalagens. O trabalho foi realizado no Sítio Santa Maria, no município de São Luis do Paraitinga, SP, durante o período de agosto a novembro de 2006, em um pomar comercial de pêssego do cultivar Aurora 2 , de três anos de idade, conduzido em sistema de vaso moderno e espaçamento de 6 x 4 m. O delineamento experimental utilizado foi em blocos casualizados, onde cada planta foi considerada um bloco, utilizando-se 15 tratamentos, 8 repetições (blocos) e 10 frutos por tratamento. Os tratamentos foram os seguintes: T1 - Sacolas de TNT branco de 45 Gramaturas por m2 (45G/m2) fechado, T2 - Sacolas de TNT branco de 45 Gramaturas por m2 (45G/m2) aberto, T3 - Sacolas de TNT branco de 20 Gramaturas por m2 (20G/m2) fechado; T4 - Sacolas de TNT branco de 20 Gramaturas por m2 (20G/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 2 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). Os resultados mostraram que o ensacamento não influenciou...
