Question
Hi Kathy,
I need help with identifying the fungus/virus of my devil's trumpet (datura metel).  It is 2 years old and has developed some kind of disease.  Loopy trails of discolored green appear on a healthy leaf, turn brown, and spread.  After a week or so, the leaf is dead.  Usually, holes and gaps show up during the process.  Do you have any idea what is causing this and how to remedy it?  Thank you for your time.
-James

Answer
Hi James..  I use Pure Neem Oil on my datura plants and it works just fine, as it is a fungicide.
Holes in the leaves could be grasshoppers or snails/slugs which come out in the evening so you don't see them.  Neem does not wash off for future protection.
