Abstract

Jujube witches broom disease (JWB), a destructive disease caused by phytoplasma (MLO), kills 3-5% or even more jujube trees each year in many orchards.
Through 10 years study and practice, an excellent new cultivar with very high level of resistance to JWB, named Xingguang was bred and released during 2005. It could be used not only to establish new orchards free from JWB, but also to re-construct the crown of diseased tree for recovering normal growing and fruiting.
At the same time, a very effective drug combination (oxytetracycline+MgSO4+citric acid) named Qufeng No.1 was screened through indoor and field experiments.
According to the results of a large scale field application, the cure rate and effective rate of once trunk injection of the drug combination given before blooming were 85 and 100%, respectively.
The cure effects of one injection lasted for 2-3 years and even more.
In addition, an integrated strategy was put forward in accordance with trees with different levels of JWB.
