 o
Apricot Tree Problem

My apricot trees which have been in the ground for three years are starting to leaf out. The first year they grew great but had a bad case of shot-hole fungus toward the end of the first year. During the winter I sprayed them with a copper fungicide at Christmas and in February during the dormant period. The following year it leafed out and grew poorly and once again had a good deal of shot-hole fungus by the end f the season. During the winter, I painted the entire tree with a combination of a neem oil and fungicide to try to get the shot-hole fungus under control. The fungicide was white hence the look of the trees - see attached picture. On one of the trees the new leaves are coming out fine although they are already showing signs of shot-hole fungus. On the others, about a week or two after the new leaves come out, they are shriveling up and turning brown on the limbs. Any idea what might be causing this ? I haven't done anything further to the trees beyond painting them with the oil and fungicide in December.

RE: Apricot Tree Problem

The tree probably suffered too much and is dead. Several years of a bad disease can sap all the energy. RIP.

For best control of shot-hole, spray copper right at leaf fall and right when leaves are about to come out. Skip the neem, its not going to help. I would also spray dilute copper through shuck split; dilute copper is around a fifth of the dormant amount.
