  • CA Dry Bean Advisory Board Request for Research Proposals - 2022

    The California Dry Bean Advisory Board is requesting applied research proposals for 2022. This commodity-based research request is sponsored by the California Dry Bean Marketing Order, under the guidance of CDFA (CA Dept Food & Ag). The Board has supported applied research by...

  • Remember to Register for the UC Dry Bean Field Day

    We look forward to hosting the UC Dry Bean Field day next Tuesday at UC Davis. This is just a reminder that, due to Covid-19 safety precautions, pre-registration is required. There is no registration fee. Please visit https://tinyurl.com/ucbean21 to register. The agenda is...

  • Using sensors for monitoring lygus bugs and natural enemies in dry beans

    An insect monitoring sensor used for counting Lygus bugs and insect natural enemies in a dry bean field, UC Davis 2021.

    Monitoring insect populations in crop fields is important for managing pests and diseases. Sweep nets have been the main tool for this task but new sensor technology is being developed to conduct continuous real-timing monitoring. This summer, the Gepts Lab at UC Davis is hosting 5 such sensors...

  • Managing root-knot nematodes in crop rotations

    Root-knot nematodes causing galling on tomato roots.

    A question came up about managing root-knot nematodes in processing tomato and lima bean rotations.  Root-knot nematodes are tiny worm-like soil dwelling pests that cause root galling on plant roots, resulting in significant yield and quality losses. Symptoms of severe root-knot infestations...

  • Why Aren't My Crops Drying Down?

    Blackeye

    We cut our blackeye bean (cowpea) research plots at UC Davis almost 3 weeks ago and they're still too green to harvest. If we tried now, the vines would get wrapped around the threshing cylinder.  Several growers in the Sacramento Valley have mentioned that their corn has sat at the same...

  • Lima Bean Heat Stress

    Figure 3. Bean plant with poor pod set. The arrows indicate where flowers did not set pods. The pictured, opened pod shows no lygus stings, suggesting that heat (and not lygus) caused poor pod set at this field.

    Last week, I visited a baby lima field in the southwest part of San Joaquin County that had overall poor pod set. Pods were filling lower in the canopy, but flowers had not set higher on the plants. The field, which was planted in late-June/early-July had an excellent stand, and ostensibly, good...

  • Ground squirrel damage to garbanzo bean pods

    Garbanzo seed pods damaged by California ground squirrels.

    Have you ever wondered about this damage to garbanzo beans where there's a hole clipped in the pod and the seed is missing (see photo)? In this case, the damage is from pesky ground squirrels that were foraging in and around our garbanzo research plots at UC Davis this spring. However, other...

  • Why aren't my blackeye bean pods filling out at the tips?

    Photo. Lack of pod fill in blackeye bean tips caused by heat, which affects pollen viability and fertilization; water stress can add to this problem, especially during heatwaves. San Joaquin Valley, 2020.

    Recently, I received a call about a blackeye bean field in the San Joaquin Valley with a lot of bean pods that did not fill out at the tips (photo). I contacted the UC Riverside blackeye bean breeders Drs. Phil Roberts and Bao Lam Huynh and they shared that this problem is primarily caused by...
