Reaction of native Cerrado and Pantanal forest species to Ceratocystis wilt

ABSTRACT

Ceratocystis fimbriata is one of the most important pathogens affecting woody plants worldwide. Management of Ceratocystis wilt using resistant genotypes in crop rotation can be an alternative to control this disease. The aim of the present study was to verify the reaction of forest species native to Cerrado and Pantanal to Ceratocystis wilt. Thus, inoculations of C. fimbriata were performed in 7 forest species native to Cerrado and Pantanal. After 45 days, disease severity was evaluated. Peltophorum dubium was the species that presented the smallest lesion length. Cedrela fissilis and Magonia pubescens had the greatest severity rates, 9.2% and 7.2%, respectively.
