Intercropping of citrus and guava trees for management of Huanglongbing [abstract]. Florida Entomological Society Annual Meeting, July 15-18, 2007, Sarasota, Florida. Paper No. 72. Interpretive Summary: Technical Abstract: Recent studies conducted in Viet Nam by Vietnamese, Japanese and Australian scientists indicate that interplanting citrus with guava negated infestations of Asian citrus psyllid and consequently huanglongbing, a serious disease caused by a bacterium vectored by the psyllid. Young citrus interplanted with guava remained disease-free for a year whereas a similar plot of citrus by itself showed signs of the disease within four months of planting and reached over 30% trees infected within a year. Observations supporting the guava effect were made in other Vietnamese groves where citrus and guava were intercropped. This presentation presents a summary of what is known about the guava effect in Viet Nam along with information gained during a trip made by USDA-ARS to Viet Nam during April 2007. |
