bacterial wilt by drench inoculation or by wound inoculation. Three strains of R. solanacearum were used for cultivar susceptibility screening, including two race 1, biovar 1 (R1B1) strains, P597 and P673, and a race 3, biovar 2 (R3B2) strain UW551

Everhart, 1895 ). Since 1954, anthracnose on azalea was observed and described in Louisiana, where the causal agent was identified as the conidial stage of Glomerella cingulata , the teleomorph of C. gloeosporioides . A susceptibility trial was carried

The response of 52 citrus hybrid rootstocks to a Mediterranean biotype of Tylenchulus semipenetrans Cobb was determined in greenhouse tests. Seven selections of the cross `Cleopatra' mandarin [Citrus reshni Hort. × Poncirus trifoliata (L.) Raf], and one of Citrus volkameriana Pasq. × P. trifoliata did not support nematode reproduction and were considered as highly resistant to the citrus nematode. The nematode showed very low infectivity and reproductive potential on seven additional selections of `Cleopatra' mandarin × P. trifoliata, one of `King' mandarin × P. trifoliata, and two C. volkameriana × P. trifoliata. These selections were considered as nematode resistant. All the selections with `Troyer' citrange [Citrus sinensis (L). Osbeck × P. trifoliata (L.) Raf] in their parentage supported nematode reproduction but showed different levels of susceptibility.
