Ongoing research

Nice to see you! In early spring and throughout most of the summer, we saw scores of digger bees, Anthophora urbana, living in our garden. The very territorial males patrolled the flowers, trying to save them for the females (to mate with them).

Hello everyone in extension! Our IGIS workshop schedule for the fall is here. We have some great workshops scheduled for your geospatial pleasure. These are coordinated with the workshops provided through the GIF.

You can "bee" one in a million. You can "bee" more than you ever thought of "bee-ing." And when you do, you'll be helping the bees, butterflies, beetles and bats.

I was speaking with a colleague a few weeks ago about field drainage in the Delta. Our conversation reminded me of a farm visit that I made a couple of years ago. I visited a corn field that was not growing well, and sections of the field had standing water.

Andy Eschbacher, Map Scientist with CartoDB, will visit the GIF to teach this special hands-on workshop.CartoDB.com is a versatile cloud-powered spatial database, mapping, analysis and visualization engine that facilitates the process of building spatial applications for both web and mobile devices.

Dragonflies! Who isn't fascinated by dragonflies? They're an ancient insect. Their ancestors existed before dinosaurs. Indeed, fossil records show that they were the world's largest flying insects, some with wingspans measuring three feet.

In late August, I visited a kidney bean field that was exhibiting stress symptoms, like necrotic leaves and stunting. Even though the field was near harvest, the consultant asked if I would take a look at it.

In late August, I was requested by a crop consultant to visit an alfalfa field in the Delta that was exhibiting symptoms like those in the picture. The leaves had little white spots near the margins, and generally, the plants had not grown well after the previous cutting.

Greetings! I started this blog as a component of my Extension program for field crops growers and allied industry in San Joaquin County and the greater Sacramento-San Joaquin Delta region.

The UC Statewide Integrated Pest Management Program (UC IPM) put together a 26-page card set in English and Spanish on understanding pesticide labels.
