SILVA, Francimar Perez Matheus da; GAVASSONI, Walber Luiz; BACCHI, Lilian Maria Arruda  e  GARCEZ, Fernanda Rodrigues. Carpogenic germination of Sclerotinia sclerotiorum under crop residues and its extracts. Summa phytopathol. [online]. 2011, vol.37, n.3, pp.131-136. ISSN 0100-5405.  https://doi.org/10.1590/S0100-54052011000300009.

The effects of crop residues and their extracts on Sclerotinia sclerotiorum are not well documented. Three experiments were conducted with crop residues and their ethanol and partition extracts. Oat, vetch, bean, pearl millet, corn and wheat were assessed under controlled conditions. Sclerotia covered with oat, vetch, bean and pearl millet residues did not germinate carpogenically. Ethanol extracts of oat and vetch residues were efficient in inhibiting carpogenic germination whereas pearl millet and wheat did not differ from control. All partitioned ethanol extracts inhibited germination. Crop residues negatively affected the number of apothecia per sclerotium.

Palavras-chave : White mold; plant extracts; apothecium; control.
