California certs/classes for PHC recommendations.

[Chris Winters]

Ive recently been introduced into the concept of PHC for the company I am working for and was wondering if you all have any insight on classes or certifications that would be beneficial to my education in the industry regarding this topic. I am looking to broaden my knowledge of both applications and chemical treatment systems. Any information would be awesome!

I have learned the most from my local university extension website, check and see if you have that resource available. Here is a free book I stumbled on. https://openlibrary.org/books/OL22592286M/Plant_health_care_for_woody_ornamentals.
