Superbrotamento de Erigeron bonariensis L.
Witches broom of Erigeron bonariensis
A. S. Costa
SUMMARY
A witches broom disease of Erigeron bonariensis L. commonly found in the state of São Paulo is described. The disease was transmitted by grafting and by dodder (Cuscuta campestris Yuncker). Mechanical transmission was negative, as well as tests with various species of insects.
Tomato plants infected by means of dodder grown previously on diseased Erigeron plant developed symptoms similar to these of the disease known as tomato big bud. The virus causing Erigeron witches broom is, therefore, considered as belonging to the tomato big bud virus complex.
