Southern Ag Dithane M-45 Fungus & Disease Control (6 Ounce)

Works as intended at a good price.

Works well

When you use this and mix it with Thiomyl, it is the perfect mix for killing black spot on Indian Hawthorn and other sensitive plants. You used to be able to purchase that mix, but it is no longer available.

This product was recommended to treat a leaf fungus problem with a legustrum tree that I have. I've treated the tree twice so far with about 10 days between treatments. It's too soon to see if there's any effect at this time, but it's easy to use. You just spoon out about 1 to 1.5 tablespoons of the powder in a few ounces of water (typically using a sprayer), connect the sprayer to a hose and spray the tree. (In my spray bottle, a gallon of water would aspirate through the bottle when the hose is connected and take up the solution in the bottle.)

This product was recommended by the company that grafted my Florida Roses. It's the best thing I've ever found to fight black spot. And in powdered form, there are many, many applications to be had. I can leave this on my lanai, because it won't freeze. Lastly, the fungi it controls don't get used to it, so you can keep applying it.

Me lo recomendó un ingeniero en agronomía, y que bien, pues está funcionando. Cómo fungicida le doy 5 estrellas, pues no lo he tratado en otro caso. Cuando lo haga completo el comentario.

Easy to use as described

This is a first-line of defense against grape diseases, and resistance is unlikely. It has a l-o-n-g PHI. I repurchase a small amount each year (and properly dispose of any left over) because it degrades in storage, something I was not aware of at one point.

I was surprised to receive a card from Royal mail to say that the product could not be delivered until a fee of £11.57 had been paid. This consisted of £3.57 VAT on this import from outside the EU and £8.00 international fee by Royal Mail. The product cost me much more than I had expected and represents poor value for money. The website did not make this clear, as it should have done. Delivery was also slower than the quoted time.
