Efeito do armazenamento na compatibilidade de fungicidas e inseticidas, associados ou não a um polímero no tratamento de sementes de feijão
[Effect of the storage in the compatibility of fungicides and insecticides associated or not to a polymer in dry bean seed coating]
Bragantia 64 (3), 459-465
Abstract: The compatibility of chemical products in dry bean seed coating associated to a polymer was studied in this work. Also, the maximum period of storage for these seeds coated with polymer and defensives was established. Dry beans, from cv. Pérola were submitted to the following treatments: 1) control; 2) carbendazin + thiram + fipronil + polymer; 3) carbendazin + thiram + fipronil; 4) carbendazin + thiram + thiodicarb + polymer and 5) carbendazin + thiram + thiodicarb. The evaluated parameters included emergency, lesser cornstalk borer (Elasmopalpus lignosellus) efficiency control and seed pathology. For the parameters emergency and borer control the best results were obtained with the treatments including fipronil insecticide. As for seed pathology, treatments with thiodicarb insecticide were more efficient, indicating a suitable compatibility of this insecticide with the fungicides carbendazin + thiram until 150 days of storage. The products tested could be used in dry bean seed dressing, and the treated seeds could be stored up to hundred and twenty days prior to planting.

Estudou-se neste trabalho a compatibilidade de produtos químicos, associados a um polímero no tratamento de sementes de feijão, estabelecendo-se ainda, o período máximo de armazenamento. Sementes de feijão da cultivar Pérola foram submetidas aos seguintes tratamentos: 1) testemunha; 2) carbendazin + thiram + fipronil + polímero; 3) carbendazin + thiram + fipronil; 4) carbendazin + thiram + thiodicarb + polímero e 5) carbendazin + thiram + thiodicarb. Avaliaram-se emergência, eficiência no controle de lagarta elasmo (Elasmopalpus lignosellus) e sanidade das sementes. Nos resultados dos parâmetros emergência e controle de elasmo, os tratamentos associados ao inseticida fipronil foram superiores aos demais; na sanidade das sementes, os tratamentos com o inseticida thiodicarb foram mais eficientes, indicando ser esse o inseticida mais compatível à mistura com os fungicidas carbendazin + thiram aos 150 dias de armazenamento. Os produtos testados podem ser utilizados no tratamento de sementes de feijão, e as sementes tratadas armazenadas por até 120 dias antes da semeadura.
