Some hosts of Pseudomonas solanacearum in Chile.
Eighteen cultivated and weed species were inoculated with an isolate of Pseudomonas solanacearum, Race 3, biovar 2, in order to determine their reaction as hosts. Eleven species were found susceptible: Solanum tuberosum, Lycopersicon esculentum, Capsicum annuum var. grossum, C. annuum var. longun, Solanum melongena, Nicotiana glutinosa, N. tabacum, Solanum sarrachoides, S. capsicastrum, Physalis floridana and Datura stramonium. A few plants of C. annuum var. grossum, D. stramonium, S. capsicastrum and P. floridana were symptomless carriers. Chenopodium quinoa, C. amaranticolor, Nicotiana rustica, Arachis hypogaea, Tagetes erecta, Solanum elaeagnifolium and Physalis phyladelphica, were found not to be hosts. From author's summary.
