Trichoderma Harzianum

This time I really need some scientific based help. This is the case: new born baby pines (pinus pinea und pinus pinaster) those are been attacked by a terrible fungus that its killing them one by one and too early before they can go to their deffinitve place or even before to get phytosanitary help.
Anyone who can told me if this advice is correct: To use a water solution using Trichoderma Harzianum that its called "good guy fungus" and supposedly can eat the "bad guys" inside the soil and save the baby roots.
The new pines are in starbuks cups with a very good (I believe) drainage. The sustratum aren't that good, but now it's to late to change it.
1. Can it help? 2. In wich cases can it help? 3. Should I ust use sulfur solution now? Pines are 2 months old 4. Should I stop the water (just spray) 5. How can I safe a very bad looking lemon cipress taht its getting dry and I'm affraid it have a problem with fungus in their roots?
Thank you very much for your answers, you're so kind to listen to me (or read me)... :)
