MARROM – Puccinia melanocephala<\/em><\/strong><\/p>\n

Hist\u00f3rico<\/strong><\/p>\n

Conhecida a mais de 100 anos<\/p>\n

Continente Americano \u2013 1978<\/p>\n

Perdas de 50% em variedades suscet\u00edveis<\/p>\n

Brasil \u2013 Novembro de 1986<\/p>\n

90 % das nossas variedades \u2013 Resistentes<\/p>\n

Substitui\u00e7\u00e3o da SP70 \u2013 1143<\/p>\n

Hoje alguns preju\u00edzos principalmente em SP 79 – 1011<\/p>\n
