RE: Large, brown dry spots
Glen, I didn't start the post but mine sometimes get as I described, and I
think it's burn; I noticed that leaves, while typically acting like a
funnel, are never all the same & some, depending on the angle of the stem
which makes some spots of leaves almost parallel to the ground, often hold
puddles. Sometimes this is worsened by wind, which often breaks leaf
veins/ribs. The broken ribs often cause browning perpendicular across the
vein from it flapping in the breeze but this something complete different,
as is leaf rub damage. You can see the brown section by using something like
daconil (white) or even seaweed (brown) & spray & see where it builds up
without running off. Chances are these areas will exhibit the shrunken brown
crispy areas. It doesn't spread (can't speak for the original poster) but it
doesn't happen immediately so people think maybe they just all of a sudden
"got something" a couple days later. I went as far as cutting the bad
section of a leaf out and brushing the edges with a captan watery paste and
3 weeks later, the leaf is completely healthy, albeit minus a pie wedge and
a white edge. Lately, I started walking around after spraying and grabbed
the leaves that had puddles & pulled them up or down to force run-off.

Does it appear and then continue to spread or is it a one time burn event? I
would tend to think if you burned areas of the leaves like the edges and
small
puddle areas on the leaf the damage would show up and be over. If its a
disease it would continue to spread within the leaf and from leaf to leaf
over
time. Dont confuse spread within the leaf with the changes of the dead parts
over
time...darkgreen/grey turns to brown crispy which gets wet and gets raggy or
floppy (scientific terms I swear!) and its not spreading...just different.
Once
its burned the rest of the leaf should be ok.......G
