Normally, we wouldn't be making a call for bugs here at IREC, but this call is different! We would like all of you photo bugs to enter the Siskiyou County Centennial Photography Contest. Please read the following details, and get your photos in by July 15. Winners will be announced at the IREC Field Day on August 13.
The University of California Cooperative Extension (UCCE) of Siskiyou County and the Intermountain Research and Extension Center (IREC) announce the 2014 UC Cooperative Extension centennial photo contest. University of California, Agriculture and Natural Resources celebrates 100 years of UC Cooperative Extension researchers and educators living and working in communities to solve economic, agricultural, natural resource, youth development, and nutrition issues.
Water/Irrigation/Drought-Photos should cover the following topics: Natural water sources, water distribution, irrigation practices and equipment, drought impact or any on farm use of water. All photos should show the impact of water in everyday agricultural practices.
4-H in Action- Photos should highlight the many aspects of the 4-H program telling the story of the volunteers and youth in action. These photos should tell a story of how 4-H volunteers and members interact with the other youth and adult organizations, communities, and the media within the scope of 4-H work.
Working on the Farm or Ranch-Photos should cover the following topics: planting, harvesting, animal care, farm labor, and working with machinery or tools. These photos should show action. All photos must show correct and safe practices around the farm or ranch.
My Scenic Farm or Ranch-Photos should be visually appealing and can cover a variety of topics including, but not limited to: farm/ranch house, barn, crops, farm animals and landscapes. People may be present in the photo, but should not be the main focus. We want to see what agriculture looks like through your eyes!
Submission Rules (Online entry due July 15, 2014):
The submitted photos must be the photographer's original work, and the photos must have been taken in Siskiyou County.
Photos do not need to be taken within the contest timeframe to be eligible to win.
The photographer must select the category for his/her entry and indicate the category on the entry form. An image may only be entered in one category, but participants may enter all categories using different images. Participants may enter up to two entries per category.
Please use high resolution photos. All photos submitted must be in JPG format. Photos with date stamps will not be accepted.

Tough water years mean tough decisions for Intermountain farmers.
UCANR along with the California Institute of Water Resources and the Strategic Water Initiative have produced a YouTube online seminar series entitled "Insights: Water & Drought." As part of this series, Steve Orloff, Siskiyou County Farm Advisor and IREC researcher, offers recommendations and consequences for making those tough decisions in this video "Perennial Forage Production with Limited Water."
While checking fields this morning, IREC Director Rob Wilson ran into some interesting guests enjoying the alfalfa. Perhaps they are collecting data for our researchers, or they are conducting their own taste tests. Either way, we welcome their company!
Tulelake is the place to be on August 13, 2014, for the Annual Intermountain Research and Extension Center Field Day! We have many activities planned, so there is something for everyone!
Our special theme this year is the celebration of 100 years of UC Cooperative Extension. Learn about the history of Cooperative Extension in Siskiyou and Modoc counties, as well as at IREC.
Take a guided field tour to learn about the important research happening here. With our researchers as our guides, we'll learn about the different crops grown in our area.
Meet with local, state and regional growers, industry personnel and UCCE staff. Share your experiences and glean insight into how to make tomorrow better. Maybe make a new friend or two.
Finally, enjoy a piece of birthday cake and home-made ice cream to top off the celebration!

Water availability is still uncertain, but the probability of maggots infesting onion fields this year is nearly guaranteed. Over the last three field seasons, we conducted several experiments at IREC examining insecticides applied at planting for protecting onion stands from maggot damage. Our results show seed treatment with OI500 (spinosad) was the most effective all three years. The next best labeled option was Lorsban applied in furrow at the maximum label rate. In untreated plots, onion stands were reduced at least 50% from maggot feeding compared to those treated with an insecticide.
During the study we trapped maggot flies to determine when adults emerge and deposit eggs in onion fields. The results from 2011, 2012, and 2013 are shown in the figure below. All three years, seedcorn maggot and onion maggot flies were found in the traps. Researchers in New York and Canada have developed degree day models to predict fly emergence based on air temperatures. Using Tulelake weather data, we compared their predicted emergence dates with fly counts from 2011-2013. Most years, the predicted emergence date came close to matching elevated fly counts.
Below is a graph showing predicted emergence of seedcorn and onion maggot using 2014 weather data. First generation seedcorn maggot flies are emerging right now, and first generation onion maggot are predicted to emerge May 21st. Seedcorn maggot is widespread and most problematic in fields with a lot decaying organic matter especially following alfalfa. Onion maggot is also widespread and infests many fields each year. Onion maggot overwinter in onion cull material and flies deposit eggs at the base of onions plants. Onion maggot is most problematic in fields located within 0.75 miles of old onion fields with cull material left in the field.
Looking at 2014 fly emergence predictions, maggot larva will attack onions at sensitive growth stages in fields planted now to mid-May. If onions maggot is expected to be problematic, consider planting in early to mid-May to avoid time flies have to oviposit on onion plants.
