Dear Certified Arborists, Landscape Contractors, Golf Course Superintendents, and Irrigation Specialists,
Just a reminder about registering for the 12/12/12 Turf and Landscape Institute to be conducted at the Etiwanda Gardens Conference Center in Rancho Cucamonga, CA on 12/12/12,by Dec. 5 for the pre-registration rate of only $85 (or $75 if 3 register online together at http://cesanbernardino@ucdavis.edu.)
6.5 ISA CEUs and 6.0 Dept. of Pesticide Regulation PCA/QAL/QAC CEUs. IA and GCSAA accreditation have also been applied for.
This year’s Institute features three breakout sessions: Sustainable Landscapes (presented in English); Arboriculture (presented in English); and Irrigation Troubleshooting (presented in Spanish). A flyer is attached.
The Arboriculture Session features crucial pest management updates on the Ambrosia Beetle/Fusarium Complex (Dr. Timothy Paine, UC Riverside) and the Asian Citrus Psyllid (which impacts ornamental landscapes as well) presented by Dr. Matt Daugherty, also of UC Riverside. Other topics and speakers include Some Undeservedly Rare Trees for the Southern California Landscape (Don Hodel, UC Cooperative Extension); Why Some Trees Fail and Others Don’t (Ruben Green, Evergreen Arborists); Overview of Tree Appraisal (Ron Mantranga, Atlas Tree Service; Pruning Deciduous Fruit Trees in Commercial Landscapes (Chuck Ingels, UC Cooperative Extension); and Urban Forest Management Toolkit (Dave Rogers, Consultant).
The Sustainable Landscape session features a full morning devoted to how California water use legislation impacts you as a professional. University of California educators/researchers and Dept. of Water Resource representatives will discuss specific practices to help ensure that irrigated commercial and public landscapes remain healthy and comply with the new MAWA (Maximum Adjusted Water Allowance based on .7 ET Adjustment Factor) regulations. Univ. of CA demonstration projects at several sites throughout CA will be highlighted. The afternoon session covers Irrigation Water Quality Considerations in Turfgrass Plantings (Ali Harivandi, UC Cooperative Extension); Weed Control Update (Cheryl Wilen, UC Cooperative Extension) and School IPM (Phil Boise, Urban-Ag Ecology).
The Irrigation Troubleshooting session (presented in Spanish) features a full day on troubleshooting irrigation problems to improve plant health and water efficiency. Topics include Troubleshooting Valves and Electrical Circuits (Toni Monzon, Bilingual Training Institute) and Wires, Connections, and Valves (Jaime Bayona, Ewing Irrigation) followed by a Laws and Regs Update (Maria Zarate, San Bernardino County Agricultural Commissioner office).
Registrants may also attend (for no additional fee) a DPR ‘Water Quality Laws and Regs’ session from 7:00-8:00 AM and Update on Laws and Regs’ session from 4:00-5:00 PM. (2 DPR QAL/QAC/PCA hours applied for).
You may pay via credit card on a secure Univ. of CA server at http://cesanbernardino.ucdavis.edu. Click ‘Environmental Horticulture’ on the left side panel of the website. If paying by check or gov’t purchase order, simply complete and fax us the registration form attached to this email.

Agenda: The field day will start with coffee and a welcome at the Orange County Great Park. Travel by bus to the Orchard Hills Avocado Grove to see native pollinators in action. Introduced to the Irvine Ranch Conservancy Native Plant Project, learn about why native pollinators matter and get an update on colony collapse disorder.
Return to the Orange County Great Park for a tour of the farm and food lab. Lunch will feature pollinator-dependent foods. The afternoon program will feature an overview of the Native Pollinators in Agriculture Project, the benefits that native pollinators contribute to California agriculture, and a panel discussion of growers’ experiences with native pollinators.
There is no cost to attend. Coffee and lunch will be provided free of charge on the tour.

A colleague recently asked me what I thought about the Iron HEDTA (FeHEDTA) herbicides that recently came on the market. I replied with, "Uh..." Turns out that she is located in northern California and I'm in southern California and I guess the iron train has not arrived down here yet because no one has asked me about it. So I decided to check it out.
I could only find a little information online where the product was tested and it was not really a planned study, more like a what I call a squirt and look experiment. Generally that's not a good sign. If something works, there are usually a lot of scientific reports about it because researchers want to see where it can best be used. Nevertheless, I wanted to try it myself so I went looking for a bottle at my local nurseries. I say nurseries because I had to go to a few to find even one product that contained Iron HEDTA. I found WHITNEY FARMS LAWN WEED KILLER although there are 4 other registered products with the same active ingredient.
Concentrate - BAYER ADVANCED NATRIA LAWN WEED CONTROL CONCENTRATE 26.5%
Concentrate - FIESTA TURF WEED KILLER 26.5%
Concentrate - IRON-X SELECTIVE WEED KILLER FOR LAWNS 26.5%
Ready to use - ORTHO ELEMENTALS LAWN WEED KILLER 1.5%
Ready to use - WHITNEY FARMS LAWN WEED KILLER 1.5%
Long story short, this stuff works. I tried it on broadleaf plantain, dandelion, woodsorrel oxalis, and black medic in a tall fescue lawn. It took about 1 week for broadleaf plantain to die and the black medic was not controlled at all. However, the oxalis and dandelion both were showing injury in 1 day and were controlled in about 3 days. There was no turf injury.
I do want to caution you that there is no soil residual although there may be some longer term postemergence activity (I hesitate to speculate that it is systemic). The area I sprayed for oxalis had new plants about 3 weeks after I did the treatment.
I'll put a longer report with photos in the next Green Bulletin (http://ipm.ucdavis.edu/greenbulletin/index.html) or Retail Nursery and Garden Center IPM Newsletter (http://ipm.ucdavis.edu/RETAIL/retail-newsletter.html)
