Insecticide Resistance Action Committee and Poster

The Utah Pests group encourages switching pesticide groups, but even we cannot remember all the group names or the insecticides that belong to them.  The poster is a handy reference.  The IRAC provides a coordinated industry response to prevent or delay the development of resistance in insect and mite pests.

CDMS Label Search

CDMS provides a huge searchable database of pesticide labels for agricultural and ornamental products.  Can’t live without this reference.

Bugwood Images

Anyone who needs to prepare PowerPoints or use images for print or online, this website is a must.  It provides an easily accessible archive of high quality images covering invasives, forestry, agriculture, IPM, plants, insects, diseases, fungi, wildlife, fire and other natural resource issues. Most images are of good quality as they are reviewed for content and quality. 

Pest Tracker

A website to report exotic pests.  It gives citizens, professionals and institutions information and maps on pest spread and progress about eradication, survey, and detection.

Science Daily

This site compiles snapshots of the latest research, and is updated daily.  There are many topics, but I find the invasive species news most helpful.

These sites are useful for identifying disease problems:
