CONTRACT HISTORY
Not applicable.
REASONS FOR RECOMMENDATION
A. Structural IPM Implementation Plans:
Initial inspection summary reports and recommendations on pest activity and related sanitation, housekeeping and maintenance issues were completed. Coordinated
recommendations for methods on sanitation, housekeeping and maintenance have been
reviewed with department IPM coordinators. These preventive methods will assist in averting pesticide applications. Summary reports are available upon request.
.
The frequency of structural inspections at residences on park grounds has been curtailed to on−call. Service inspection frequency at other facilities within Department of Parks & Recreation and Department of Roads & Airports has also been reduced from monthly to quarterly/alternate month or on−call. This will assist departments to focus resources on implementation of preventive measures as recommended.
.
B. Landscape maintenance & related pest management services:
A landscape maintenance RFP was released on August 8, 2003, but was withdrawn for revisions in contract language. It was reissued on October 9, 2003 with a closing date of November 14, 2003. The Procurement department is expected to complete the contract paperwork by December 2003. The Landscape Maintenance IPM initial surveys for County grounds & facilities will commence effective January1, 2004.
.
A primary objective of this area of activity is to implement a strategic plan for maintenance of county turf and landscape areas. Proactive maintenance of a healthy landscape through timely monitoring, and sound cultural and mechanical practices will preserve long term investments, effectively manage recurring maintenance costs and avert continuous use of pesticides.
Although some in−house landscape maintenance is performed, outsource services are also used as needed. Services that are not possible within department budgetary resources will be

managed through the landscape maintenance contract. Demonstration and trials will also be possible through the landscape contractor.
.
In addition, the County IPM Coordinator is working closely with the GSA, Roads & Airports and HHS Custodial & Grounds Maintenance on a case−by−case basis to perform field surveys and respond to pesticide application requests.
.
C. Posting of Pesticide Use: Land signs will be in use with commencement of new landscape maintenance contracts. These signs will be ordered and distributed to the user departments as soon as the new landscape contract is signed.
.
D. Pest Management & Pesticide Use − Record Keeping & Reporting: Electronic data base development work continues to progress. Two additional planning and development sessions were held during this quarter. Estimated completion time has been extended with launch expected in January 2004.
.
E. Pesticide Use Exemption: Four (4) pesticide use exemptions, per Section B28−5 of the IPM Ordinance, were granted in the last quarter:
. 1.Use of Pyrethrums for control of honeybees infesting a structure at Santa Teresa Park
. 2.Use of Sulfuryl Fluoride (Vikane) fumigation to control dry wood termite infestation at
Sunnyvale Superior court: fumigation to be performed on Thanksgiving weekend
. 3.Use of Sulfuryl Fluoride (Vikane) fumigation to control dry wood termites infestation at
272 Curie Drive, San Jose (Structure at Santa Teresa Park): fumigation date to be decided.
.
4.Use of Treflan E.C. & Grass preventer (a.i. Trifluralin) Franklin McKinley project to sterilize aggregate base (soil sterilization). This exemption was given after the fact. The contractor has been notified to obtain use exemption in advance.
.
The following use exemptions are under consideration for this coming season:
. 1.Use exemption for Pre−Emergent herbicides (Surflan, Oust, Gallery: these products are not on County's approved list of pesticides) is under consideration. The IPM Coordinator is reviewing the subject matter in consultation with Cornell University, Department of Roads & Airports, Department of Parks & Recreation, Department of Agriculture, and the Fire Marshall. The Department IPM coordinators are working to define high−risk areas based on road safety and fire hazard standards. Pre−emergent herbicide applications to

high−risk areas will be granted on season−by−season basis until viable alternatives are carefully evaluated for wide scale adoption. Pesticide applicator safety education training, scheduled for November 12 & 14, 2003, will also address this issue.
. .
. 2.Use exemption for Termidor (Fipronil 0.006%) liquid spray application to control
argentine ants is also under consideration on case−by−case basis.
.
F. IPM Projects & Demonstrations aiming at Pesticide Use Reduction: The IPM projects and demonstrations provide sites where hands−on education about IPM is coupled with relevant, "real−world" examples. Full reports on demonstration site visits are available from the IPM Coordinator.
. 1. California Ground Squirrel & Pocket Gopher trapping projects :
.
A trapping project is underway throughout park facilities to emphasize trapping over the use of chemicals to control ground squirrels. Rodenticide has not been used on the County Parks in the last quarter, as per the Department of Parks IPM Coordinator. It is hoped that trapping will gradually replace the rodenticide use in County parks and other open spaces, making rodenticide last resort component of IPM.
. .
.
It is encouraging to report that neighboring counties and city agencies have shown interest in this approach and adopting the protocol. The Department IPM Coordinator has also been asked to present this protocol to County of San Mateo's IPM workshop.
. Reed Hillview Airport has also started a trail project on pocket gopher control using black
hole traps.
. .
.
2. Stinging Arthropod control: Yellow jacket trapping trials were conducted in the last quarter and a protocol was set to intercept yellow jackets on seasonal basis. Protocol is available upon request.
. .
. However, since the ban/withdrawal of Diazinon (organophosphate), and non−availability of abatement chemicals for yellow jacket control, presence of these insects in the
recreational areas is on the rise. Structural infestation of honeybees is another challenge to be dealt with. Besides trapping, control for these pests is limited to "Search & Destroy" actions, such as those followed by fire departments and other emergency response groups. To respond in such emergency situations, three reduced risk pesticide products (Exempt

IC (Rosemary Oil), EcoPCO Jet (Eugonol/Phenothyl Propionate), and EcoExempt D (Clove Oil/Phenothyl Propionate)) have now been included on the approved list of pesticides.
. .
. With increased human intervention, through both search & destroy actions and honey
beehive removals, departments are expected to incur higher cost to mitigate these pests.
.
At the request of the Department of Parks & Recreation, the IPM Coordinator is
developing an informational brochure for park users to increase awareness of the hazards of venomous arthropods while visiting wilderness areas.
. .
.
3. Argentine Ant Control: A precision baiting efficacy trial will soon be set to demonstrate alternatives to liquid spray application and minimize non−target exposure. The County IPM Coordinator is making tenants aware of sanitation and building maintenance issues and their role in mitigating this problem in some county facilities.
. .
.
4. Aquatic Weed Harvester: Two demonstrations took place this quarter, one at Lake Vasona (Department of Parks & Recreation) and the other at the Los Gatos percolation ponds (Santa Clara Valley Water District). The Department of Parks & Recreation is considering use of this technology to mechanically manage aquatic weeds in ponds and lakes. Utilizing this technology will minimize or eliminate the aquatic herbicide usage.
. .
. 5. Vegetation Control:
.
Mulch as means of Weed Control: It is known that use of quality mulch offers cost savings over its life cycle besides environmental benefits. The Department of Roads & Airports is developing a demonstration: Mulch will be applied on selected road clovers, medians and landscape. Once proven, phase−in of remaining acreage under such sites will be completed in next 5−10 years with in the budgetary framework. The Department of Parks &
Recreation will follow a similar strategy.
. .
.
Use of Clove Oil formulation in post emergent vegetation control: This project will be expanded to airport taxiways and right of ways at Ed Levin Park. The County IPM Manager is currently negotiating a collaborative trial with the manufacturer. We are also negotiating for better prices for large orders from the distributor/manufacturer. Cost economics studies will be done once efficacy trials are completed.

. .
.
Right of Way vegetation control: During FY02−03, pre emergent herbicide use was completely withdrawn from all weed management applications and impact studies were completed. Careful consideration of road safety and fire hazard issues indicates that use of pre emergent herbicide in Priority 1 areas should continue until a suitable and cost
efficient alternative is found.
. .
. Finally, a number of studies/protocols have been identified for further study this year in
the area of vegetation control.
. .
. G. IPM Awareness, Education & Interactive Application:
.
1. IPM Outreach: During the past quarter, the County IPM Coordinator participated in education and outreach through speaking engagements at the Santa Clara County annual safety seminar, the Professional Association of Pesticide Applicators annual seminar (PAPA), the annual meeting of California Pest Control Advisors (CAPCA), a meeting of Parents for Safer Environment (Moraga, CA), Putting IPM into Practice (a workshop organized by Santa Clara Valley Urban Runoff Pollution prevention program (SCVURPPP).
. .
.
2.Staff Training: Staff education, training, and refresher courses are important
components of a successful program. A six (6) hour pesticide applicator training was held November 14 & 16, 2003, for all pesticide applicators and managers with
Department of Roads & Airports and GSA Custodial Grounds. Department of Parks & Recreation staff will undergo this training in February 2004. The objective of the training is "Reducing Risk through IPM education & Pesticide safety". The cost of approximately $200 per year to furnish this training in−house will allow cost savings of $3000−4000 for departments by eliminating the need to hire outside contractors to provide similar training.
. .
. 3. Annual IPM Training: As many agencies have IPM−related needs for training, plan development, and evaluation, a collaborative process has the potential for maximizing collective resources, sharing costs, and providing benefit to cities, the County, and other key agencies. The County IPM Coordinator is continuing efforts related to establishment of a countywide annual IPM training program. Estimated cost for the

first year is $28,000 and $20,000 in subsequent years. Details of a draft proposal and budget are attached to this report.
. .
.
4. Public Awareness: Two brochures are being developed by the IPM Coordinator. One will focus on public education about IPM; the second will promote the County's efforts. These brochures will introduce the concept of IPM to diverse audience, helping to encourage more active participation in the development and implementation of IPM plans. An initial print run of 10,000 copies will be produced at an estimated cost of $6000.00.
