Hello, My farm has seen major die off in our greenhouse plants due to a fungal pathogen (so we think). Plants droop and after three days are completely dead. When inspecting the soil I have found blue and white colonies of some type of fungus that I believe is some kind of trichoderma. I am not sure if this is the root cause or an opportunistic fungi. I dealt with this issue about six months ago and added hypochlorus acid to my irrigation mix as an antimicrobial and it seemed to get rid of the issue until now. I have also sent leaf and root tissue samples to another lab for pythium and fusarium and all tests came back negative for those specific pathogens. So, I am looking to find a lab that could do a broad spectrum pathogen test on infected soil from plants I just killed and see if we can get a more exact idea of what type of pathogen we are dealing with. Can your lab provide such a test? If so, how big of a sample do you need and where does it need to be sent. Let me know if you guys can help us out and then we can work out the logistics. Feel free to reach out via email or I will also leave my cell phone number below as well.

I have a friend who recently purchased a small apple orchard and wants to learn about fruit tree grafting. For Christmas, I would like to get them a book or a class related to this. Can you recommend a book, class, or other resource related to fruit tree grafting?

My pressure canner gauge is at 2 lbs before starting. Can I go to 12 lbs to adjust for a 10 lb recipe? Or is it just unusable?
