Re: need help with sick sdc
 

abnshrek, you are right about the cold.they did start when the cold nights came.

i do use a 4 month osmocote, with bi weekly liquid ferts. i stoped just befor bringing inside.

Re: need help with sick sdc
 

It appears to me to be neither. Yellow and Black Sigatoka have a distinct fungal pattern of specks that start on the leaf.

Black Sigatoka:




Might be fertilizer burn?

lookin' ight... are you keeping an eye out for spider mites and nematodes?

Re: need help with sick sdc
 

hi justin,well i have been looking for spider mites, but what do i look for nematode problems?

Re: need help with sick sdc
 

Sorry I can't answer well. . . red inside the roots would indicate, nematodes are microscopic. . . I use pesticide on mine to prevent anything. . . You should be okay as long as you're using "new" soil (not used by others plant) but tissue cultures are suppose to be disease-free.

thanks justin.i use a soiless mix in containers.roots looked fine when i repotted in august.but pots were set on mulched ground. maybe i should check for signs of nematodes.oh, yes i do use new mix.tennessee nursery mix type.
