@Ahmad Could you share your experiences with apricots and Captan burn? I know Captan is labelled for apricots and I remember an old forum thread that discussed the issue of burn. If I remember correctly most people had not experienced Captan burn on apricots but you were one of the unlucky ones which I am curious about the conditions you experienced burn.
I noticed this post of yours made about having problems with damage after spraying Captan with copper. Have you had burn after spraying Captan by itself?
I remember when I started out I was concerned with the risk of Captan burn on sweet cherries but I was reassured that it was rare by advice given on the forum. Here is the thread.
