Ilama seedlings dying.

[Chandramohan]

My Ilama seedlings, after putting out 4 leaves are dying one after the other. I notice that the roots have become black and rotted. What could be the reason? Please help with advice.

Were they treated with GA3 and became etoliated?

[tallman]

To much water in the substrate?

[Chandramohan]

They were treated with 350 ppm GA3. But I do not think they are very much etiolated. Will too much of GA3 cause them to die? I do not think it is too much of water.

Too much water?

[lebmung]

GA3 makes the cells elongated and sensitive to light use less 50mg/l

[Guanabanus]

Too much water and root rots.  Some Subdue and /or Alliette might help.

Also make sure the growing medium has nutrients.

[Chandramohan]

Thank you. I already applied 'Ridomil' when the first seedling wilted and after two more died I have applied 'Carbendazim'. I have reduced water. The growing medium has nutrients.

GA3 can make seedlings not only elongated but more vulnerable to becoming a casualty from other causes.Damping off and dying back like that is nearly always due to soil fungus. Whether phosphonate or Alliette will help I don't know but clean premium potting mix to start the seedlings out is important.

My Ilama seedlings are now fine. Carbendazim seems to have cured the problem. It was probably a 'Fuserium' infection.
