NAVARINI, Lucas et al. Chemical control of soybean rust (Phakopsora pachyrhizi Sidow) in soybean crop. Summa phytopathol. [online]. 2007, vol.33, n.2, pp.182-186. ISSN 0100-5405.

The efficiency of different fungicides rates applied at various soybean stages was evaluated to control Phakopsora pachyrhizi. Soybean cultivars used in the field trials under natural infection were: RS 10, BRS 154, CD 201, BRS 153, CD 206 and CD 209. Results showed significant variation on yield after two fungicide applications. The sequence of fungicides and the inoculum level at the experimental area were important to establish the efficacy of fungicides in the control of the disease. Strobirulins applied at R1 growth stage had the best performance and the preventative control resulted in the highest efficacy.

Keywords : Strobirulins; host growth stages; preventative control.
