UC IPM offers 26 online courses. All courses are free. To get continuing education units (CEU) and a CEU certificate for completing a course, there are course fees. In addition to the California Department of Pesticide Regulation, many of the courses are also accredited by the California Structural Pest Control Board (SPCB), Certified Crop Advisor (CCA), Western Chapter of the International Society of Arboriculture (WCISA), or Arizona Department of Agriculture.

Diagnosing Herbicide Injury provides information on how to investigate crop injury when herbicides are the suspected cause. It includes information on how herbicides injure plants, how long herbicide symptoms may last, possible scenarios of herbicide exposure based on injury patterns observed in the field, and how to prepare samples for laboratory analysis.

The new online course was developed by UC Cooperative Extension specialists Brad Hanson and Kassim Al-Khatib, with UC IPM instructional designers Petr Kosina and Cheryl Reynolds. If you are a grower, pest control adviser, or pesticide applicator, then this course is a great opportunity to learn about how to approach a crop injury investigation when herbicides are the suspected cause.

Confirming herbicide injury can be tricky. Disease and nutrient deficiencies or toxicities can closely resemble the injury symptoms caused by herbicides. If it is in fact herbicide injury, the economic implications of herbicide damage can vary—in some cases visible injury may have very little direct economic effect, while in others even slight herbicide symptoms can affect the marketability of the crop. In addition, the presence of an unregistered herbicide on nontarget crops can result in illegal residues that could have both safety and legal consequences.

Take the course to learn more about herbicide injury symptoms. Diagnosing Herbicide Injury is accredited by the California Department of Pesticide Regulation (1.5 hours Other), Certified Crop Advisor (1.5 IPM), and the Arizona Department of Agriculture (1.0 credit)

Managing Ground Squirrels and Pocket Gophers provides information on the description, biology, and ecology of ground squirrels and pocket gophers as well as an overview of available control options including habitat modification, trapping, baiting, and fumigants.

This course consists of eight video segments with UC Cooperative Extension Specialist Roger Baldwin and was developed by UC IPM instructional designers Petr Kosina and Cheryl Reynolds. The course, originally presented as part of the UC Ag Experts Talk webinar series, was developed for pest management professionals and growers to better understand the importance of IPM in vertebrate management.

Managing Ground Squirrels and Pocket Gophers has been approved by the California Department of Pesticide Regulation for 1.0 continuing education unit in the Other category and also by Certified Crop Advisor (CCA) for 0.5 unit of IPM credit.
