Department of Pesticide Regulation Proposes Restrictions in Urban Areas to Protect Water Quality
SACRAMENTO - Businesses that provide structural pest control would be required to follow strict new controls that limit where pesticides are applied around structures to protect water quality under regulations proposed today by the California Department of Pesticide Regulation (DPR).
“Surface water monitoring data collected for the state’s regional water quality control boards and monitoring by our staff continue to show that pesticide runoff in both urban and agricultural waterways exceed levels toxic to some small aquatic organisms,” DPR Chief Deputy Director Chris Reardon said. “Most people don’t realize that pesticides used to control ants, spiders and other pests in and around homes, commercial and industrial buildings and landscapes can affect aquatic life.”
While pesticide use is closely associated with agriculture, more than half of the products regulated by DPR are for commercial, industrial and home use, Reardon explained.
The rules would restrict the use of 17 pyrethroid insecticides by businesses that apply them to homes, other structures and landscaped areas -- not pesticide use by individual consumers. In addition to decreasing the amount of insecticides used around structures, the regulations would prohibit pest control applicators and maintenance gardeners from making applications when it rains, when puddles are present and over drains and natural drainage areas.
The intent of the regulations is to reduce pesticide contamination in runoff from homes and other urban structures, driveways and landscaped areas into surface water. Pest control businesses and maintenance gardeners apply more than 70 percent of the pyrethroids targeted by the proposed regulations.
DPR has long encouraged more environmentally friendly pest prevention and control strategies through grant funding and recognition. The proposed regulations incorporate changes suggested by pest control businesses and other stakeholders during workshops and numerous discussions over the past two years.
“The proposed regulations are a cost-effective way to protect water quality,” Reardon said. “Many pest control businesses are already offering site evaluation and customized pest control rather than routine spraying of pyrethroids.”
Following adoption of the proposed regulations, DPR plans to follow up with additional restrictions on pesticide use in agricultural areas in 2013 to protect surface water from further contamination.
More information about the proposed regulations is posted on DPR’s website at: http://www.cdpr.ca.gov/docs/legbills/rulepkgs/11-004/11-004.htm. The deadline for public comments is 5 p.m. Dec. 12. They can be submitted by e-mail to dpr11004@cdpr.ca.gov, by fax at 916-324-1452 or by mail to Linda Irokawa-Otani, Regulations Coordinator, Office of Legislation and Policy, Department of Pesticide Regulation, 1001 I St., P.O. Box 4015, Sacramento, CA 95812-4015.
One of five departments and boards within the California Environmental Protection Agency, DPR regulates the registration, sale and use of pesticides to protect people and the environment. Additional information about DPR is posted at www.cdpr.ca.gov.

I gave a presentation (same one I did at the FarWest Show) today and was asked to post it. Unfortunately, I haven't had time to figure out the new website program (sorry DK!) so I'm putting it here.
It is called "Are you spending too much on weed control?" and it is geared towards container nurseries.
Are you spending too much on weed control?

I was playing with our new puppy today and was rolling around on the back yard with her. As it turns out, there is also a birdbath where we were playing and I happened to look up when I was under it and found a bunch of burr-like sacs underneath.

These are egg sacs of the brown widow spider and the sacs are so distinctive, that even I knew what they were. Here is what they look like to me:
I even found the spider itself and have to say it was a lot smaller and more delicate than what I expected. Even though its overall size is about the size of a quarter, the body is tiny, like a drop of water.

The IR4 Program helps expand pesticide labels for use in minor crops such as ornamental plant production.
Western US issues are often put in at a lower rank because growers in the east and midwest participate more in priority setting surveys including the one I link to below.
If you want to have a say in what products are going to have targeted testing, you NEED to fill out this survey.
Participate today in the Grower & Extension Survey:
The survey is available on the IR-4 Website.
Preliminary Survey Results:
Top 3 plant disease categories:
1. Crown and root diseases (not caused by water molds)
2. Bacterial diseases
3. Powdery mildews
Top 3 pest categories:
1. Thrips
2. Mites and spider mites
2. Borers and beetles
Top 3 weeds:
1. Liverwort
2. Bittercress
3. Spurge

I don't want anyone to miss out on my latest post even if it's somewhere else. I just put something up of the UC WEED SCIENCE blog. See "Summer means polarized sunglasses" http://ucanr.org/blogs/UCDWeedScience/index.cfm
I also want to alert you to a meeting coming up on August 27 at the South Coast Research and Extension Center in Irvine.
Pitahaya (Dragon Fruit) Festival and Field Day
I'll be talking about Pitahaya IPM (Gophers, Birds, Snails and Weeds).
See the EVENTS section on the right side of the San Diego UCCE web page or go directly to it here.
