Using mancozeb after after flower blooming!

Hi, as discussed with you before, I used mancozeb during dormant period (June/July) and again just before bud swelling in mid/end of August. The problem of leaf curl has improved, but still I find some leaves with leaf curl disease. Flowers have bloomed already in my trees; fruits are about to form. Is it okay to continue spraying mancozeb at this stage at 10 days or 2 weeks interval? Please advise.

Mancozeb is registered to control a range of fungal diseases in apple, pear & stone fruit trees, however not leaf curl.  Apply at full blossom, petal fall then every 3 weeks in stone fruit.

A better solution is Leaf Curl Copper Fungicide Spray:
