The Insect and Mite sections of the UC IPM Pest Management Guidelines for Dry Beans have been recently revised and updated and are now available online at: UC IPM Dry Beans Pest Management Guidelines.
Authors include UCCE Farm Advisor Rachael Long and UC IPM Advisor Pete Goodell (emeritus). The guidelines include an updated photo page to help identify pests and the damage they cause to dry beans at: Photo Identification.
These guidelines can help with managing pests in your fields. Interested in Lygus bugs and how to control them? Take a look at the guidelines on lygus and see that the thresholds vary by bean class and type. For example, blackeye beans (cowpeas) have different tolerance levels to lygus than lima beans. Some lima bean varieties are more tolerant to lygus than others. Interested in biocontrol of aphids? See photos of natural enemies that prey on aphids at: Photos to identify natural enemies of aphids.
There is also a newly revised table on the relative toxicities of insecticides and miticides to natural enemies and honey bees in dry bean production, found at: Insecticide Toxicities.
This information and much more is available through the newly revised 2018 UC IPM Dry Bean guidelines! This follows the recent revision of diseases and abiotic disorders in dry beans. The weed management section is currently in review and will be available later this year.

UC Davis Agronomy Farm
Directions: In the field across from the UC Davis Bee Biology Lab (same place as previous years). From Hwy 113 in Davis, exit on Hutchison Dr. Go west, turn north at the first roundabout, then west at the second roundabout. Continue west on Hutchison Dr for about 1 mile. Turn south on Hopkins Lane (look for a row of olive trees), make your first left, and park under the trees. For questions, contact Rachael Long at 530-666-8143. No RSVP needed.

The Diseases and Abiotic Disorders section of the UC IPM Pest Management Guidelines for Dry Beans have been recently revised and updated and are now available online at UC IPM Dry Beans Pest Management Guidelines.
Authors include Farm Advisors Carol Frate (emeritus) and Rachael Long and UC Davis Professor Paul Gepts. Two new diseases were added, including pythium in established plants and chocolate blotch on limas. The Fusarium wilt sections were also consolidated and new photos were added throughout the guidelines. This includes an updated photo page to compare common diseases and abiotic symptoms to help identify them (Photo Identification).
With the upcoming planting season for dry beans, these guidelines can help with managing diseases in your fields. Worried about southern blight? Yes, beans are susceptible and you'll need to rotate to a non-host crop, including corn or grains for at least 2-years to reduce the inoculum. How about alfalfa mosaic virus? This disease is transmitted by aphids from alfalfa fields, so avoid planting beans adjacent to alfalfa. This information and much more are available through the revised UC IPM Dry Bean guidelines!
The remaining pest management sections, including insect pest and weed management, are in the process of being revised and will be published soon!
