Comparação de dois métodos de sanidade na detecção de Alternaria helianthi em sementes de girassol

Abstract

Comparison of two health methods in the detection of Alternaria helianthi in sunflower seedsThe objective of this work was to compare the efficacy of the blotter test and agar method to detect Alternaria helianthi associated to seeds of sunflower (Helianthus annuus) produced in some regions of Brazil. In general, higher incidences of the fungus were registered in blotter method.

Establishment of a semi-selective method for the detection of Sclerotinia sclerotiorum in dry bean and soybean seeds

“…Part of those fungi may take over the whole container of seed incubation very quickly and others may change the color of the substrate in a similar way as S. sclerotiorum. For those reasons, plating seeds on blotter substrate impregnated with Neon-R ingredients may be an alternative that should be considered for routine seed analysis for the detection of S. sclerotiorum, as reported by Salustiano et al (2006).…”
