Citrus greening disease problem and management in the Asian region

Citrus greening disease is supposed to have originated in South Asia specifically in China and spread throughout South Asia.
The management of this disease is becoming more difficult and more time and money-demanding year after year.
The management practice in the past was applied in bits and pieces, but it did not have very encouraging results.
Some useful traditional practices such as disease-free sapling production and distribution, vector control like inter-cropping with guava, use of pesticide and yellow sticky traps, and elimination of host plants are in operation in this region but that is not enough.
Some novel technologies are coming up from the USA, Brazil, and European countries.
A spray of kaolin to the standing plants to impair the vision of citrus psylla, use of antibiotics with the help of trunk injection techniques, hormonal sprays, identification of scion and rootstock combinations that are tolerant to the greening diseases and development of transgenic cultivars, growing citrus under protective cover and screens, and cover crop which attracts vector and later killed by natural predators are effective control measures verified as very effective in other parts of the worlds but introduction and utilization of such technologies in South Asia is sluggish.
Packaging all available indigenous and exotic technologies as integrated disease management practices and quick adoption is crucial to save this region’s citrus industries.
A pathway to get these technologies from the Western world and adoption mechanisms in the Asian region has been proposed in this paper.
