Dessa forma, objetivou-se determinar os patógenos associados a sementes de pinhão-manso, para possibilitar o desenvolvimento de estratégias de controle dos mesmos. Para o teste de sanidade, utilizou-se o método do papel de filtro (&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;em&gt;&lt;span style="font-weight: normal;"&gt;blotter test&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;span style="font-style: normal;"&gt;&lt;span style="font-weight: normal;"&gt;), modificado com restritor hídrico NaCl - 1,0 MPa, e avaliação após sete dias de incubação, a 25ºC, com fotoperíodo de 12 horas. As sementes de pinhão-manso analisadas apresentaram alta frequência de espécies fúngicas, independentemente da desinfestação superficial das mesmas. Foram observados 19 gêneros de fungos, destacando-se &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;em&gt;&lt;span style="font-weight: normal;"&gt;Alternaria alternata&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;span style="font-style: normal;"&gt;&lt;span style="font-weight: normal;"&gt;,&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;em&gt;&lt;span style="font-weight: normal;"&gt; Colletotrichum&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;span style="font-style: normal;"&gt;&lt;span style="font-weight: normal;"&gt; sp., &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;em&gt;&lt;span style="font-weight: normal;"&gt;Fusarium&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;span style="font-style: normal;"&gt;&lt;span style="font-weight: normal;"&gt; spp. e &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;em&gt;&lt;span style="font-weight: normal;"&gt;Rhizoctonia solani&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #000000;"&gt;&lt;span style="text-decoration: none;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span lang="pt-BR"&gt;&lt;span style="font-style: normal;"&gt;&lt;span style="font-weight: normal;"&gt;, os quais são comumente patogênicos e devem ter sua relevância considerada.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
