Some years ago an elderly gardener told me of a control for Brown Rot in stone fruit and that was sprinkling Sodium Carbonate under the tree.

Sodium Carbonate is known as Wallys Soda Ash Dense. I tried it and it certainly reduced the problem greatly without any other spraying.

I wrote about this and later on, had another gardener contact me and said it worked on their curly leaf problem as well. Another told me it helped with keeping their rose foliage better from black spot.

Been a fine powder it is easier to spread and get a good coverage and it breaks down quicker having a pH of 11 when added to water which is weakly alkaline.
