BonideMancozeb Flowable with Zinc Fungicide, 16 oz Concentrate, Broad Spectrum Disease Control & Prevention for Plants

Great stuff. I've had big problems the last 2 years with blight killing my tomatoes but this product KILLS THE FUNGUS. I even had one plant that was 2-3 days away from me pulling it up the fungus was so bad. Literally 90% of the plant was engulfed in fungus. But 2 days ago I found this same plant had sprung a new strong limb! This was after I soaked this plant with Mancozeb a few days earlier. The product STOPS fungus cold. To be safe I am rotating this with Daconil so it's Mancozeb 1 week and then Daconil the next and so on to keep the fungus from adapting. The leaves that were infected before don't recover and have to be snipped off but the fungus is stopped from spreading. The product needs to be sprayed on regular intervals though since rain and weather can remove it. This is the stuff the pros use and if you live in a southern state with hot and humid summers you should try this fungicide in your garden. It KICKS A$$!1-1.5 tablespoons per gallon is the recommended amount I have read online. I just looked again at the container booklet and it doesn't seem to have these smaller dilution numbers. Also when I spray I totally soak the plants and leaves to get complete coverage. 1 tablespoon per gallon has been working well for me so far but you can go to 1.5 tablespoons if needed.

Worked well for my tomatoes and pickles. He held back to Disease pretty much all summer with many applications of course

This is a liquid concentrate, application mixture varies with crop and type of plant disease targeted, an example mixture would be - Grapes, powdery mildew, 1-3 Tablespoons per gallon.

Read the label! Great prebloom product. Be aware, not spray on fruit/crops within 66 days to harvest. You can also mix with copper based fungicides.

Oh my gosh! This stuff REALLY works - immediately. I planted new miniature roses this spring and was instantly plagued with nearly every sort of fungus imaginable - black spot, rust, and powdery mildew. In spite of good care - plenty of sunlight, impeccable drainage, watering close to the soil and repeated application of "organic" remedies, the leaves just kept falling and falling off my little guys. I saturated my roses with a fairly aggressive mixture of Mancozeb and made sure it was allowed to dry thoroughly on the plants. Boom! I lost a few more leaves that were already infected and that was that. In less than a week, my roses have new healthy growth and no more leaf loss.I contacted Bonide customer service for follow up care. Cindy was awesome. She suggested using Rose Shield in 10 to 14 days and repeating every 14 days after that. I just planted two new roses and doused them with Rose Shield for prevention. So far, so good. The Bonide Fish Fertilizer she also recommended is stinky stuff, but my roses seem to love it as well as my fuschias.My advice - don't waste time with other remedies. Get the Mancozeb, follow the directions exactly and your roses will thank you. Just be careful not to inhale or get the product on your skin. Wash and clean up diligently afterward.

OMG I FINALLY found something to help my roses. I live in north Louisiana where we have extremely hot and humid summers. Springs have very warm days and cool nights which all of the above are perfect for blackspot outbreaks. I have tried what I feel must be everything on the market to no avail. The FIRST spray stopped most of it. Sprayed again in five days and there are NO blackspot leaves anymore. I also sprayed the mulch under the roses. If you are on the fence about this product for roses BUY IT, IT WORKS!

Remember that this is nasty stuff, which requires protective gear and much care during application (see instructions). In view of this, the bottle, and more specifically the "safety cap", should not elevate the hazard - but it does. The cap is of the "press down and turn" variety, and is difficult to open - moreso with continued use. The cap liner becomes mushy and falls out of the cap at opening. (To replace it, your gloved hand has to touch the concentrated fungicide.) As per directions, it is necessary to mix up the contents well before using; one time the bottle leaked while I was inverting it. (Hazardous mess to clean up.) I had the bottle begin to collapse (see photo where arrows point to new creases in the bottle) when pressing the cap down with a turn, to try to open the bottle. I suspect the difficulty opening is because of the thick fungicide solution seeping into the threaded portion. So now it seems I must wipe down the threaded region (and inside of cap?) after each use. Fun, fun! Transferring a hazardous material into a new container is generally considered a bad practice, but I'm considering it.Three stars only because I think mancozeb is a good fungicide.

Works as expected
