ที่มาเลเซียพบปัญหาเรื่องกล้วยๆ คือ ไม่ใช่ เรื่องกล้วยๆ มันคือเรื่องกล้วย (บางครั้งภาษาไทยเรามันก็ทำให้วุ่นวายในการจะสื่อ) ปัญหาที่พบคือ :
My Research short note:
Name: Moko Disease or Bacterial Wilt
(formerly called Pseudomonas solanacearum)
Cause : Ralstonia solanacearum
Soilborne : can survive in soil 2 years
Transmission : rain splash, soil, infected host, mechanical and insects
Host : majority dicots exception being bananas and plantains
Favorable conditions : High temp. and high soil moisture.
Site of infection: through wounds in the roots.Obstructing the uptake of water and soil nutrients.
older leaves : turn yellow and wilt, become necrotic and collapse.
younger leaves: turn pale green and turn necrotic
central leaves: break at a sharp angle while still green.
young plant and suckers : wilt, candle leaf, turn black, become stunted or twisted.
older plants : the inner leaf first turns yellow near the petiole.
petiole : breaks down, and the leaf wilts and dies.
vascular tissue: discolored in the center , when cut and dip in the water exudes bacterial ooze.
fruit : ripen prematurely or split, internal part the fruit becomes discolored and eventually rot.

Prevention:
1. Soil Fumigation with Basamid G.
2. Destroy source of inoculum by Glyphosate injection into the diseased plant or burn.
3. Resistant variety
4. Crop rotation
5. Cultural practices : drainage
6. Probiotic Treatment :
6.1 soil treatment with mineral that have a fungicide and bactericide property.
6.2 Neutralize soil pH
6.3 Inoculate a beneficial microorganism
