HIS Inspector's Guide
​The idea of a nursery inspector’s guide was conceived at the Founder’s meeting in 1970 to update an old publication that was being utilized by the Central Plant Board (CPB). The first segments were produced in 1976. The idea fully got off the ground in 1984 with the costs being shared 50/50 with the CPB. Inspectors wrote each insect or disease reference and provided color photos. The first printing in 1985 included 165 entries covering 10 pests and was provided to each inspector.

In 1991 it was considered complete and was produced with a comb binding to allow updates and revisions to be added as new pests and diseases have emerged. The Inspector's Guide was reformatted to include recommended regulatory actions, with reference articles covering 63 insects and mites, 37 diseases and nematodes, and 3 environmental problems.
​
The pest write-ups cover the distribution, description, hosts, damage, life cycle, inspection tips, control tips, related pests, and references. The Inspector's Guide was designed to be a reference manual that would both assist with diagnosis, and to serve as a guide to help produce uniform enforcement of plant regulatory laws.

In 2025, the CCHIS began the process of producing and printing a completely revised and updated manual to keep up with current pest and disease issues and to reflect changes in regulations and treatments. 

If you would like to be notified when the newest manual is available for purchase, please email our treasurer, Liz Meils.
