Bonide Sulfur Plant Fungicide, 4 lb. Ready-to-Use Micronized Spray or Dust for Organic Gardening, Controls Common Diseases

After trying a few other things for the extensive powdery mildew infestation, I purchased this. It worked in one try. I've been spraying weekly with a Copper Fungicide & even tried a home remedy with Baking Soda. But nothing was touching my powdery mildew problem. I saw this & figured I'd try something else. In one application, it has obliterated the mildew which is especially bad this season. It does have a slight sulfur smell but nothing too awful. And I can live with a mild smell if it kills the powdery mildew. Will definitely be using this the next time I have an outbreak.

I use this product on all of my Desert Roses to keep the fungus down in the hot humid summer months. Makes a great drench for pots as well as a spray for the foliage. Even works well when used for cuttings. I think it's safer to use than copper as it will not burn the plants.

This powder is pure sulfure and effective in fighting mold, and fungi on plants, and may deter thise annoying wet mold gnat flies in house plants. It can also help adjust the soil Ph. However, it claims it is "wetable," and you "can add powder to garden sprayer bottle," but it clogs the sprayer if you have any other chemicals, especially the oil based ones added to enhance clinging to plants' leaves, bark. Still recommend purchase as it is a naturally occurring element that gets the job done without the addition of poisonous forever chemicals.

pure sulfur in the bag, no issues. i may have bought too much, i think im set for life. hooray sulfur cream

It's a pain to mix with water for a spray, but that's the nature of sulfur. I put 3 Tbs in a bowl with some water & mush it around until the sulfur is wetted before adding it to 1 fallon of water in a sprayer. Use a plastic sprayer to prevent corrosion & shake as you spray to keep it mixed. (I have to get it under leaves to get mites & the only way to do that is by mixing it with water.)

A great product from a reputable brand, but I was surprised to find that the plastic bag it is sold in is not resealable. So I have a bag full of fine powder that I need to keep closed with a clip or something.

With all of the rain we have had this summer, my newly planted Blue Chiffon Rose of Sharon came down with a fungal infection. I hate using treatments that involve a lot of chemicals that may be harmful to the environment so this seems to be a good choice for me. I did need to purchase bulb duster (very inexpensive) but no big deal. I put it on in the evening and was amazed that the fungus cleared up after only one application. My shrub is looking very happy now. One reviewer freaked out about the dust ruining the appearance of her plants. It does what it needs to and then washes off in the next rain (or you can hose it off after a few days).

Does not mix well in water as the package says, clogged up my sprayer.
