UC Davis and UC Cooperative Extension will host the UC Dry Bean Field Day on Thursday, August 15, 2024 from 9:30am to 11:45am. The field day will begin at the Agronomy Field Headquarters (2400 Hutchison Drive) on the UC Davis campus. From the Agronomy Field Headquarters, follow the UCCE sandwich board signs to the field location. Look for the pop-up tents. The agenda is pasted below, and a downloadable version is attached to the bottom of this post. DPR continuing education (1.0) is pending. CCA continuing education credits have been approved (1.0 Crop Management, 1.0 Pest Management). Light refreshments will be provided. Thanks for your interest, and we hope to see you at the field day!

Between 22 and 27 Feb, Ascochyta blight in garbanzo beans was detected in the Five Points/Lemoore area.

This disease has potential to cause economic damage, is favored by wet conditions and moderate temperatures, and rain is in the forecast for Friday, March 1^st and Sunday, March 3^rd.

Fungicides, such as Endura (boscalid), Headline (pyraclostrobin), or Quadris (azoxystrobin) applied to garbanzo foliage preventatively will reduce risk of loss due to this disease.

Consult product labels carefully before applying a fungicide treatment to ensure the most effective application method, timing and rate.

Here are recent resources for more information about Ascochyta blight in garbanzos:
