Help with fruit tree disease

Hi everybody,

There's an apricot tree in my mother's garden (in the south west of France) and it seems really sick.

I took some pictures. Can you help me find a natural treatment for this?

Thanks!

It's difficult for me to see what's going on with the picture of the leaf, but the couple dark spots on the leaf lead me to think it's a blight. The mighty split in the bark going down the trunk is a canker in my opinion, and in the second photo of the trunk, the small dark vertical "gash" below the branch union appears to be another canker appearing. The third photo also looks to me to have several small cankers on the trunk.

Well, usually a vigorous healthy tree can fight the diseases and heal those cankers, but it looks like there may be a question regarding the health of the tree. I have fruit trees myself and mix a foliar spray containing Effective Microorganisms, molasses, a biological disease control called Serenade, raw unfiltered and cold processed neem oil, and a little natural soap as an emulsifier. The microorganisms will attack a lot of disease pathogens aiding the tree. The neem oil will disrupt the life cycle of insects (like borers) that will find the cracks in the bark from the canker and lay eggs in the cambium tissue just beneath the bark. Wounds on tree bark are open doors to pests that can cause real problems and I know borers can be a real problem in north america, but I am unsure of what sort of pest pressure is experienced in europe. I not only spray the leaves of my trees but all the branches and trunk as well. Also, quality compost and even sawdust & wood chips can be scattered thickly on the surface of the soil beneath the tree and out past the drip line to help slowly feed the tree and improve the soil.
 
Been there. Done that. Went back for more. But this time, I took this tiny ad with me:
