Intensidade de poda verde em pessegueiro para controle da ferrugem Tranzschelia discolor (Fuckel) Tranzschel e Litvinov Rust Tranzschelia discolor (Fuckel) Tranzschel and Litvinov control by green pruning in peach

Abstract

Com o objetivo de se avaliar o controle da ferrugem [Tranzschelia discolor (Fuckel) Tranzschel e Litvinov] em pessegueiro 'Flordaprince' [Prunus persica (L.) Batsch], duas intensidades de poda verde foram realizadas aos 45 dias após a colheita: poda leve e poda de renovação. O experimento foi realizado em condições de campo, no Departamento de Produção Vegetal da ESALQ-USP, em Piracicaba-SP, entre novembro de 2004 e janeiro de 2005. O delineamento experimental adotado foi inteiramente ao acaso, com dois tratamentos e doze réplicas. A parcela experimental correspondeu a duas plantas em espaçamento 3,0 x 1,2 m e conduzidas sob sistema de líder central. A avaliação de incidência e severidade de ferrugem foi realizada em folhas de quatro brotações por parcela, sendo duas por planta. As avaliações foram conduzidas de 33 a 81 dias após a poda verde, em intervalos de sete dias, utilizando-se de escala diagramática adaptada para a ferrugem. Os dados referentes à incidência e severidade de ferrugem foram submetidos, respectivamente, ao teste exato de Fisher e ao teste de Wilcoxon. A incidência e a severidade de ferrugem aumentaram com a idade das folhas, independentemente do tipo de poda verde empregada, atingindo, respectivamente, 81,95% das folhas e 1,43% de área foliar lesionada, aos 81 dias após a poda verde. A poda de renovação não reduziu os níveis de ferrugem em pessegueiro 'Flordaprince' em relação à poda leve, a partir dos 40 dias após a poda verde.Rust [Tranzschelia discolor (Fuckel) Tranzschel and Litvinov] control in peach [Prunus persica (L.) Batsch] cultivar 'Flordaprince' was evaluated through the use of two green pruning levels performed 45 days after harvest: light pruning and renovation pruning. Experimental works were conducted at University of São Paulo, Piracicaba-SP, Brazil, from November 2004 to January 2005. Experimental design was completely randomized with two treatments and 12 replicates. Experimental unit was comprised of two plants under central leader's system in a high density orchard (2777 trees ha-1). Incidence (% of diseased leaves) and severity (% of lesioned leaf area) were evaluated weekly from 33 to 81 days after green pruning in four shoots per experimental unit. Data were submitted to Fisher's Exact Test (rust incidence) and Wilcoxon's Test (rust severity). Rust lesions increased with leaf age regardless of pruning level. Rust incidence and severity were, respectively, 81, 95% of diseased leaves and 1,43% of lesioned leaf area, 81 days after green pruning. Renovation pruning did not decrease rust leaf lesions in 'Flordaprince' peach from 40 to 81 days after green pruning.
