Leaf Blight...

  1. Alright so in another thread of mine, thanks to you guys' help I discovered one of my plants had leaf blight. I'm wondering now, how often to spray the copper sulfate on them. It's been showering on and off here a lot lately, so I've been spraying them after every time it rains. Can you over use this stuff? The plants seem to be not getting any worse, they still look nice. Thanks for any input :)
  2. Reapply anytime rain washes it off or every 12 days if it doesnt rain. Be sure and use 2ozs per gallon as lower doses may allow some of the spores to survive. Any surviving spores will reproduce and be totally resistant to the LC. It will have no effect on them at all.

    Its also highly contagious and if one plant has it, the others will soon. Spray them as well.
