FANTASTIC
SAVED my water propagations-- they finally stopped rotting!!

A magical potion!
This stuff is great! It is the elixir of life for my tomato plants! They are big and lush this year. Last year my tomatoes got some sort of funk and this fugicide was recommended on one of my garden sites. It was too late last year to save my tomato plants - it was late in the season anyway. But this year I gave my tomato bed a good soil drench of this before I planted and I used this to water them in, giving them a nice shower of the solution too. They are so healthy and I have lots of green tomatoes on the vine! I ordered more just to have on hand at the first sign of trouble. My only issue with it is the bottle opening. For whatever reason, I cannot measure it out without some of it dribbling down the side of the bottle. Maybe a future redesign of the bottle?

Great for leaf miners and tomato hornworms
I sprayed a fine mist of this well-diluted product on my cucumber plants. Getting ready to apply again after 3 weeks. It made a big difference in saving the plants as leaves were dying in mass from leaf miners. In addition to the leaf miner and tomato hornworm control, it saved a young peach tree that was dropping leaves severely from some kind of spider mites forming webs. The tree is growing new leaves! I noticed some 1/4 inch hornworms on pepper plants and will spray late this afternoon before leaving for a week. All this pest control from a product that will not poison me and my family. Highly recommend this bacterial control.

Works
So far it seems to be working fine but it’s definitely not a one treatment thing. After a few times of applying it you’ll start to see less of the bad stuff. And a plus that I didn’t know is that the bacteria in this can be used as a bio fertilizer. My grapes leaves darkened up after a few uses of it and they look better than I’ve seen them and that’s no other fertilizer added so that’s a bonus. Plus if you do a soil drench the bacillus will colonize on the roots and protect them from pathogenic fungus and bad bacteria.so it’s more than just a foliarfungal preventative . Definitely added to my arsenal. Live in the panhandle of Florida and the disease and insect pressure is pretty intense where I am

Excellent!
It's the same ingredient as Hydroguard, but at a much higher concentration so I can use a fraction for the same application. This saves me a lot of money and I highly recommend it.

Amazing Plant Recovery
One of my best tomato plants started getting that "drool" look to it. I ordered Southern Ag Fungicide. By grace of Cosmos Amazon got it here fast and I immediately used it that evening. Now, 24 hours later it looks back to normal on par... I mixed it strang and poured it over the whole plant- I didn't spray it- i poured it and saturated the roots and all the plants around it. No pruning, super hot weather that is totally humid to the max and weeds everywhere... Is a recipe for disease. So now that I don't have to pull this wonderful plant maybe I should address those other things I can do but baby believe me this Southern Ag Fungicide works. I also applied it to about 20 foot more of congestive plantings. I am amazed and happy that hopes of not having early/late blight and all the rest or just being able to grow my stuff is so finely trancending to my soul so I can go out and prune, weed, keep my leaders staked on lines and can some food for jars you open in winter that are summer in a bottle. love it!

Perfect fungicide for my indoor garden project.
This product works great in my recirculating deep water culture screen of green garden setup. Applied at a rate of 1ml per 20 gallons of nutrient solution, it makes for a great companion and backup to my chiller to effectively help prevent mold, mildew and other rootzone and nutrient solution problems. This product is very affordable compared to products such as hydroguard and it's much more concentrated.

So far, effective against wilt
Last year a wilt killed all my tomato plants by June (probably Verticillium wilt). Plants had spots and wilting leaves by May. Cucumbers also had a similar affliction. This year I planted in all new soil, in containers - but most of the plants got the spots after the very first rains. I've been applying this stuff for 4 weeks or so, as per label, and the disease seems to be controlled. No new leaves are affected, and the plants are thriving. The conainer is small, but you only need 1tsp - 1tbsp per gallon, so it goes a long way in a home garden. I'm still on my first tablespoon. I doubt I'll need to buy more this season, and shelf life is not specified (but some studies suggest that this bacterium should last more than a year at room temperature).
