Identifying nontarget crop and ornamental plant damage from herbicides has become much easier, with the launch of a new online photo repository by the Statewide IPM Program, University of California Division of Agriculture and Natural Resources.
Dr. Kassim Al-Khatib, weed science professor at UC Davis and director of the UC Statewide Integrated Pest Management Program (UC IPM), has gathered nearly a thousand photos of herbicide-damaged plants, drawn from his own and others' research. The images are cataloged to show damage that can occur from 81 herbicides in more than 14 specific herbicide modes of action, applied in the field to demonstrate the symptoms or when known herbicide spray has drifted onto the plant.
Each image is characterized with the name of the plant, mode of action of the herbicide, and notes the specific symptoms of damage. Together these photos provide a comprehensive archive of damage to over 120 different crops and ornamental plants by known herbicides, which users can easily compare with what they see in the field.
Also included in the repository is information about the modes

There is a new online course from UC IPM designed primarily for PCAs and licensed pesticide applicators. This course is based on a series of pesticide resistance workshops held in Davis, Fresno, and Kearney in 2014.
The course explains how resistance has developed among fungi, insects, and weeds and how it can be managed.
2.0 "Other" CEUs are available from the Department of Pesticide Regulation.
The course contains:
- Narrated modules with short quizzes throughout.
- A final test for each module.
- Selection Pressure, Shifting Populations, and Herbicide Resistance and Tolerance
- Glyphosate Stewardship: Maintaining the Effectiveness of a Widely Used Herbicide
- Preventing and Managing Glyphosate-Resistant Weeds in Orchards and Vineyards
- Managing Glyphosate-Resistant Weeds in Glyphosate-Resistant Crops
You can find this course on our web site at:
As a reminder, this course does NOT run on Internet Explorer 9 (IE9) or later versions of IE and will not accurately track your scores in those browsers. Please use IE8, Firefox, Safari, or Chrome. Sorry for any inconvenience this may cause./span>
Press Release from USDA:
Release of Endoparasite for the Biological Control of Asian Citrus Psyllid
APHIS published a draft environmental assessment on September 18, 2014 for the proposed release of Diaphorencyrtus aligarhensis for the biological control of the Asian citrus psyllid in the United States.
We will consider all comments that we receive on or before October 20, 2014.

The UC Riverside Veterinary Entomology Extension Laboratory has developed an on-line database of pesticides registered in the State of California for use against arthropod pests of animals. The database can be found at: Website visitors can search by animal commodity for which pest control is needed (e.g. poultry), by type of pest (e.g. poultry mite or house fly), and by application method and formulation. It is expected that animal producers and extension personnel will find this database to be much easier to navigate than the California Department of Pesticide Regulation product search website.
Animal producers may also be interested in other offerings of the Insect Pests of Animals website (). Visitors can find pest management information for some ectoparasite pests of poultry, cattle, and other animals. We are adding information on additional pests every few months so be sure to check back to see what has changed. We also maintain a Blog () that producers and extension personnel may be interested to follow. Information shared through the Blog includes recent findings related to pest management in animal facilities or of general relevance to animal producers, extension personnel, and researchers.
Finally, animal producers may be interested in taking a look at the many web links provided in our “other resources” section. In particular, there are links for producers to submit animal management questions to the national eXtension program through their “Ask and Expert” program. Experts from universities, extension offices, private industry, and other relevant organizations are registered with this national eXtension program to answer submitted questions or to provide question writers with guidance to address their questions.
