Review: Powdery Mildew Killer - 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.
Review: Safer to use than other products out there - 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.

## Questions & Answers

**Q: does thisproduct  Control Powdery Mildew, Rust,and  Scab Mites and is it simular to garden sulfur by lilly**
A: Our tomato and pepper plants were completely wiped out the year before, so this last season when the leaves started to droop, we did research and found this product on Amazon.  We received the Bonide in three days, dusted them, and never lost a plant.  The plants were healthy and we grew large crops.  I highly recommend this product.   . . . .  I bought two new dusters, but the simple one by Hudson works best.

**Q: is it toxic to cats?**
A: This is a natural sulfa mineral powder. It is anti-fungal agent. If a lot is ingested it would probably give the cat the runs, however if used properly and your cat like mine simply was around it, then no. I have 2 indoor cats who stray into our backyard and a  feral cat which is adopting our deck. 
I've used this for several years without any noticeable ill effects.

**Q: I want to cut the top off of my pillar cactus.  Can I just sprinkle this stuff on the cut edge of the pillar to help it heal?**
A: Yes applying sulfur powder to a cactus cut is common practice as it prevents molds and fungus from forming on the open cut while it heals and scabs. You can also apply a rooting hormone to the cut to expedite the rooting process

**Q: Will the smell of this sulfur be enough to keep deers from eating forming buds on fruit trees?**
A: I've never seen anything that compares to ammonia for deterring deer or anything else.Its a noxious odor they respect and safe to use outdoors.Place on strips of cloth and tie to branches or fencing.

### ⭐⭐⭐⭐ Gardening Pulverized/Powdered Sulfur
*by A***H on July 19, 2024*

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.
