Great for Blight
This works great on plant fungus and diseases. Works great on Bligh. We had a very humid summer and unfortunately I did not pretreat my plants with Captain Jacks beforehand so as to avoid Blight completely. Instead we sprayed all affected plants when we saw it coming on and it worked great! I sprayed it every four days for a couple weeks which brought it under control and then maintained by using every two weeks.

Knocks out Blight and Black Spot!
Used as directed (maybe mixed a tad stronger than directed) and it knocked out some early blight and black spot in my veggie garden. Was able to save many plants that would otherwise been tossed on the burn pile.

It truly does work
It actually works. Last year sprayed on heavily molded garden and it killed it along with the leaves affected. New growth had no mold. This year I sprayed after the heavy rains but prior to any mold. Also poured some in the ground for the roots to absorb. Wow. EVERYTHING IS NOW IN BLOOM WITHOUT EVEN ONE HINT OF MOLD. My roses, wild flowers, and the flower bushes that usually are solid mold by now...ABSOLUTELY NO MOLD. The area I live in has mold and plant rust rampant in the air. Entire neighborhood gets deeply infested every year. But NOT ANYMORE. You really can't go wrong with this. And it doesn't harm the butterflies or bees and birds. Only drawback is that it is a dark neon blue and will stain hands, clothes, walls, fences, etc. So cover up and be mindful how you spray. Small price to pay for the benefits. Good luck.
