BARROS, Rosana Gonçalves; BARRIGOSSI, José Alexandre F. and COSTA, Jefferson Luis da Silva. Effect of the storage in the compatibility of fungicides and insecticides associated or not to a polymer in dry bean seed coating. Bragantia [online]. 2005, vol.64, n.3, pp.459-465.

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.
