A critical-point yield model to appraise the damage caused to soybean by white-...
Reis, Erlei M.; Zanatta, Mateus; Juliatti, Fernando Cezar; Campos, Hercules D.; Silva, Luis Henrique Carregal P.; Meyer, Maurício C.; Nunes Junior, JoséA model to estimate the damage caused by white mold to soybean yield from experimental field data gathered during the summer season of 2009-10 was generated. Six soybean cultivars were grown on six sites of the Cerrados region, resulting in a total of nine separate experiments. The gradient of disease intensity (plant stem incidence) and yield was generated through the application of different fungicides and ra...
Meta-analytic modeling of the decline in performance of fungicides for managing...
Ponte, Emerson M. Del; Lana, Felipe Dalla; Paul, Pierce A.; Godoy, Claudia V.; Utiamada, Carlos M.; Silva, Luís Henrique C. P. da; Siqueri, Fabiano V.An apparent decline of fungicide performance for the control of soybean rust in Brazil has been reported but the rate at which it has occurred has not been formally quantified. Control efficacy and yield response to three fungicides applied as single active ingredients (a.i.)—azoxystrobin (AZOX), cyproconazole (CYPR), and tebuconazole (TEBU)—and four applied as mixtures—AZOX+CYPR, picoxystrobin + CYPR, pyraclos...
