Agra Quest 708510A Serenade, 32-Ounce Garden Disease Control,Ready to Use, fl oz

I'm glad I bought this organically acceptable spray. I used to it prevent powdery mildew. The ingredient of this product is the only thing known to work against powdery mildew (which btw occurs during dry spells, not damp times). This product worked well in my personal plot in a community garden in which plots a mere 2 feet away were awash in powdery mildew. I used it on a strain of heirloom peas which have no powdery mildew resistance bred in. This spray saved my crop. I know powdery mildew can skip plots, but previously at this time of year my plot was always stricken like its neighbors. Not this year. I used the product as directed. Stood upwind, wore gloves, sprayed until it ran off the plant. Did not water within 4 hours of spraying. Used it every 7 days. It worked very well, but the smell is strong and truly putrid and fetid, like the time the dog found a rotting dead squirrel. Gag. The smell lasted for about 2 days and on the second day was still noticeable 6 feet away.

This is a good fungicide. It was effective at quickly killing mildew on a squash plant, at least on the exact spot where it was applied. But I had a bad case and the mildew would return within a week or two. Even though I applied this product weekly, I was never able to fully eradicate the infection and the plant never set fruit. Next, time, I will use it preventively, before the mildew starts. Yes, it does smell pretty foul, and you don't want to get it on your skin or clothes, but its not unbearable and the smell dissipates as soon as the leaves dry.

I have been organic gardening for several years now. Like every gardener, I have issues that sometimes require commercial intervention. This year, I'm trying to be proactive. I live in south Louisiana which is very hot and humid right now, not to mention several days straight of wet weather. Of course, every year is the same battle with some sort of fungi/disease/critter invading my growing garden. Growing organic you learn there are certain things you just have to live with, while other things you've gotta battle head on. I started seeing small signs of brown circles surrounded my yellowing, which is a sure sign of a fungus. Something I deal with year after year. After reading the reviews of this product on several websites I turned to trusty Amazon for speedy shipping.This arrived as expected on Saturday (yesterday). Sprayed on all my tomato plants in the evening after all the pollinators have left for the day. When I went out to the garden today, I have millions of tiny, brown spots on every leaf. Even the new leaves are covered. I don't understand it! Does anyone else have this issue?I noticed the mixture has a very putrid smell that reminds me very much of "Critter Ridder", so maybe this is an old mixture or bad batch? I'm clueless. All I know is that yesterdays solution is now todays mess. I will be returning this product and nursing my tomato plants back to health in the mean time.

Got this because I had some rust spots on my mint leaves and some brown spots (fungus) on my tomato plants. Applied this liberally over the course of a week (every other day) in the morning. After some pruning and this spray, my plants are fungus free and are looking good. Overall, I am very happy with this product and I would not hesitate to recommend to anyone.

I was frantic. The Campari tomatoes I'd grown from seeds had come up in their pots beautifully and were just breaking into flower when suddenly the tops just flopped over into wilt! I went online and discovered that it was likely caused by some sort of fungus. My searching led to this product, and as an Amazon Prime member, I was able to get it delivered inexpensively by the next day.It was like the cavalry came over the hill. The box showed up promptly, I pulled out the product and tore open the protective plastic bag on my way out to the garden. I read the instructions which basically said, just HOSE the plant down, so I did. Mind you, this stuff smells really horrid, so you definitely don't want to be downwind even from a slight breeze, and you can poison yourself if not careful.But by the next morning, all was straight up and green, except for the lowest branches that had gotten seriously yellowed and which I removed. Now the plants are almost 4 feet high and loaded with flowers and growing tomatoes.This stuff is organic, and the label says that one can continue to use it right up till harvesting time if need be. And I discovered that one spraying was not enough. Apparently my garden here in Florida is so mold prone that I need to respray about every 7 to 10 days. The stinky smell doesn't linger. My plants smell like tomato plants should, and the tomatoes don't have any weird, mutated look to them. I'll just be sure to wash my harvests down very thoroughly.The only downside to this product, and any other spray bottle I've ever used, is that after the first few sprays the product begins to drip a bit onto your hand while using. So you should probably wear gloves while spraying. Also, if I'd known about the fungus situation ahead of time, I'd have gone for the mix-and-spray-with-hose larger version of Serenade so I could have covered the whole garden and surrounds in preparation, and perhaps warded off bad fungus for the duration. Spritzing with the bottle is time-consuming, but was definitely an effective triage for the emergency situation I encountered.

This products is amazing. I spray it on my grapevines. We have mildew in the springtime with our weather in the Pacific NW. I saw it coming and sprayed my vines thoroughly. I saw a bit of mildew on a vine, so I sprayed it and the mildew went away. As the grapes matured, I had NO mildew on my grapes and beautiful grapes this year.
