2023 UCCE Blackeye Bean Variety Evaluation

UC Cooperative extension experts led by Michelle Leinfelder-Miles evaluated blackeye bean varieties in a commercial field in Stanislaus County in 2023. The season began with cool and wet spring conditions, which lasted through the month of June and delayed planting. Seven varieties from the University of California blackeye breeding program were planted on July 7th. The varieties were grown on …

Aphid ‘honeydew’ May Promote Bacteria that Kill Them

The word ‘honeydew’ sounds benign, but the sugary waste product of aphids can promote growth of bacteria that are highly virulent to the pests, according to a new study. The research takes a step towards understanding how some strains of the bacteria Pseudomonas syringae that live on leaves and are pathogenic to aphids might one day be used to control …

Black Beans Help Fix Insulin Resistance and Gut Bacteria Balance

USDA ARS — Adding cooked black beans to a high-fat diet improved sensitivity to insulin and other measures often related to diabetes and restored gut bacteria balance in obese mice, according to a USDA Agricultural Research Service study. As little as the mouse-size equivalent of a single serving a day of black beans—about a half cup for a human—lowered insulin …

New Dry Beans from UC Davis Combine Qualities for Both Farmers & Consumers

Many consumers desire heirloom-type beans, which have great culinary quality and are visually appealing. On the other hand, farmers desire beans with better disease resistance and higher yield potential. The bean varieties that …

New Bean Defeats Both Leafhoppers & Drought

Agricultural Research Service (ARS) scientists in Puerto Rico have developed a new pinto bean germplasm that may increase a farmer’s yield, reduce production expenses, and help the environment. The new bean, called TARS-LH1, is resistant to two types of leafhopper – Empoasca fabea, the potato leafhopper, which can reduce common bean yield by 20 percent in temperate areas, and the tropical leafhopper, E. …

New CA Blackeye Varieties Show Resistance to Cowpea Aphid

Field trials in the Central Valley with two new varieties of blackeye beans, CB74 and CB77, show impressive resistance to cowpea aphids compared to standard CB46, CB5, and CB50 lines. Four varieties of blackeyes including CB46, CB77, CB74, and CB5 were seeded into a blackeye CB50 field, in single lines on 30-inch beds in the Sacramento Valley in May 2020 …

Fusarium Root Rot in Seedling Lima Beans

In May, I looked at a lima bean field in the Sacramento Valley that showed poor seedling emergence scattered throughout the field (photo 1). I sent samples to the UC Davis Plant Pathology lab and the main pathogen consistently recovered from the roots was Fusarium root rot, a fungal disease caused by Fusarium solani f. sp. phaseoli. This pathogen is specific …

Keeping Pinto Beans Away from the Dark Side
