As I write this in early April, the weather is shifting back and forth between being warm and cold and there is the occasional rainfall. Many of you have started or are thinking about starting ground work in preparation for planting. With all this going on, I ask you to imagine what it would be like for your farming operations if you could plant a rice field in mid-April. Later this week, we are planning to plant our first research plots on a summer stale-seedbed (fallowed last year and worked in the summer into a seedbed) using a no-till planter. The ground is firm enough to support equipment, we have taken care of our winter weeds and the seed will be planted into moisture. On top of that, we have rain in the forecast for the weekend. Once planted, these rainfall events are helpful.
If the soil is dry, how early one can plant really depends on temperature. Daily average temperature (average of daily minimum and maximum) should be 60oF. Historically, this average falls between April 10 and 15 in the Sacramento Valley. The other consideration if you are planting early is the availability of water. The seeds need to have water to germinate. You cannot always rely on rainfall. Sometimes it may be hard to plant to moisture. In these cases, you need irrigation water. If you have an irrigation pump, you are free to decide when to plant and irrigate your field. If you have to rely on district water, you will be more restricted in your planning.

Growers Invited to Avocado Lace Bug Presentation
On May 14 at 12:30 p.m., Paloma Dadlani — a graduate student under Dr. Mark Hoddle who has been spearheading avocado lace bug research funded by the California Avocado Commission — will deliver her master's thesis defense seminar. Interested California avocado growers can view the thesis defense online or attend in person at the UC Riverside Entomology Building located at 165 Citrus Drive, Riverside, CA.
The thesis covers the following topics:
- Effects of temperature on developmental and reproductive biology, and degree-day models. This work helps predict development times in the field and will inform growers on possible levels of control from hot weather events.
- Two years of population phenology data from four commercial Hass avocado orchards in San Diego County, and surveys for ALB on non-Hass avocados like GEM, Lamb Hass, Bacon, and Fuerte. Natural enemy surveys are included, and sticky card captures to monitor adult dispersal by flight.
- Updated molecular analyses on ALB populations in San Diego county (the original 2004 population in Chula Vista and National City are still there), including comparisons to the "aggressive" populations in northern San Diego County, Riverside, Los Angeles, and Santa Barbara Counties and the extremely damaging populations in Hawaii.
