Can anyone identify this brown trouble in the pics? The plant seems healthy otherwise. This started on one leaf and has spread. I have a fungicide/pesticide spray but am not sure if I should spray it since it is a succulent. It almost slightly looks like some pics of spider mite damage I have seen, maybe? Any advice would be greatly appreciated, thanks!
This is from Bangalore,India. (13 deg. North Latitude) Twice or thrice a similar problem occurred to my Adhenia too. All leaves fell off. However, all recovered uneventfully as the doctors say. I have started to spray Sevin as I have seen some woolly aphids at the leaf tips prior to leaf fall. The problem has not recurred. bioramani
