SBCWMA Newsletter                                                                    November 2006

 

Hello SBCWMA Newsletter subscribers:

 

I want to point out that the USDA CSREES grant deadline for researchers to submit a letter of intent to study the biology of invasive plants in agriculture is December 6, 2006. – News item found in “Grant Opportunities”.  I also am including a new feature – Weed of the Month – starting with Oxalis latifolia in this month’s newsletter.  And… note the news item, listed first below, for a significant opportunity to influence the federal government on how they will regulate plant imports into the United States.

 

Thank you.

– David Chang

Cal-IPC’s Nearly $Half Million Grant Proposal to Map Arundo Statewide Recommended for Funding (10/25/06)

            Cal-IPC’s proposal for $412,500 for "Arundo donax (giant reed) Complete High Resolution Regional Mapping: Salinas to Tijuana" has been recommended for funding.  (Decision will be finalized at State Water Board meeting in November.)  This project, when combined with data from Team Arundo del Norte, will move Cal-IPC a long way's towards having a good statewide map for arundo.  This will be good for strategic planning and for supporting funding needs for addressing infestations.  If you are working on arundo projects or know about arundo infestations in Santa Barbara County, expect Cal-IPC and me to be asking for your help.

 

Florida Transportation Department Agrees to Help Battle Destructive Plants (10/27/06)

            Florida's Department of Transportation (FDOT) has joined an effort promoted by The Nature Conservancy to control invasive species, agreeing, among other things, to encourage use of alternative plants in landscape projects.  The FDOT refined the Voluntary Codes of Conduct developed for government agencies and will incorporate them in their statewide policy for roadside landscaping and other related business practices.  The Department is the first government agency in the country to sign on.  Click here for the complete press report.  

 

Milestone Herbicide Registered in California (10/25/06)

            Milestone herbicide (generic ingredient – aminopyralid) was accepted for registration by CalEPA on October 4, 2006.  Click here for a copy of the label.   Following is a statement Beau Miller emailed to WMA coordinators:

            “As you have probably already heard, Milestone will become the new standard for noxious and invasive weeds, including tough perennials like artichoke thistle, Canada thistle and Russian knapweed.  At this point there are over 50 weeds on the newly approved label.  A second label version is already under submission which has over 90 weeds and woody plants on the label-- stay tuned for that one in 07!  So you get the idea that this broad-spectrum, reduced-risk chemistry herbicide is great for all kinds of difficult-to-control weeds such as yellow star thistle, Scotch thistle, and the knapweeds.   Milestone has both pre- (up to 4 months) and post-emergent activity on these weeds at use rates of 3-7 oz per acre. 

            Since Milestone does not affect grasses, range & pasture forage can be demonstrably improved with early (December through March) applications to control yellow star thistle.  The benefits of application often persist for one or more years after treatment with very high performance on labeled weeds, as almost all of the longer-

term evaluations demonstrate.   

            Milestone also has some woody plant activity – look for additions to the label and blends of our actives for superior woody plant control in the future.  With some woody activity, Milestone will not be as selective as Transline, especially on desirable small trees that have to be sprayed over the top.  There is a Milestone tree bulletin available.

            Milestone has a broad label with range & pasture, general non-crop vegetation management and a long list of natural use sites that you will want to check out in more detail.  It may be applied up to the water's edge in many areas, but not on the inside banks of irrigation canals.  For irrigation canals, it will be OK to apply from the top hinge of the inner bank, including the top and outside banks.”

NatureServe Adds 28 I-Rank Assessments to Their Website, NatureServe Explorer (11/10/06)

            NatureServe has added U.S. invasive (I-Rank) assessments for 28 plants to their website, NatureServe Explorer, http://www.natureserve.org/explorer/.  This brings the total number of assessed plants to 480.  The I-rank assessments are the result of applying a systematic protocol (Morse et al. 2004) to determine the degree of impact an individual non-native species has on the native plants, animals, and ecosystems of the United States.  NatureServe’s hope is that these objective and transparent assessments will build consensus and galvanize action.

            This is an excerpt from Kat Maybury’s, (Botany Dept. Director of NatureServe), original announcement.  I saved the original announcement that lists the 28 new plants and gives directions for accessing the site.  Contact me to obtain the original announcement.

 

Steve Schoenig Update on CDFA WMA Grants (11/13/06)

            $1.5 million was recently added to CDFA’s budget to fund noxious and invasive weed management.  Request for proposals were due in October.  Steve Schoenig, CDFA scientist and administrator of the WMA statewide program provided an update on the proposal selection process.  Following is that update.

            The selection committee met November 1st to evaluate and score proposals.  CDFA staff have compiled these scores and submitted them to Integrated Pest Control Branch management for evaluation.  A recommended funding allocation will be sent up for final approval and awarded grants should be announced in the week of November 27th.

 

DPR Reports 2005 Pesticide Use Data; Highly Toxic Categories Down Again (11/14/06)

            This is not exactly weed related, but I thought of enough interest to include, here.  This is a nearly verbatim, (formatted differently) reprint of the original DPR news release. – dc

            (Editors/reporters: See county pounds statistics and rankings www.cdpr.ca.gov/docs/pur/pur05rep/lbsby_co.pdf and the 2005 Pesticide Use Report Summary with "top" data lists www.cdpr.ca.gov/docs/pur/pur05rep/05_pur.htm  )

            The California Department of Pesticide Regulation today reported a statewide decline in the use of several highly toxic chemicals in 2005, including fumigants and other pesticides of regulatory concern.

            DPR tentative statistics for 2005 show 194 million pounds applied for all commercial uses, compared to 180 million pounds in 2004. Half of the increase was attributed to sulfur, a natural compound used by organic and conventional growers to combat mold and mildew. Wet weather was a factor for many growers in 2005.

            At the same time, use of many higher risk chemicals declined, both in pounds applied and acres treated, while use of some reduced-risk compounds increased dramatically.

            "DPR continues to put strong emphasis on reducing pesticide risks and use whenever possible," said DPR Director Mary-Ann Warmerdam. "While last year's weather presented challenging conditions for growers, we see a growing reliance on sustainable pest management.

            "The number of pounds applied is not as significant as the chemicals that contribute to that total," said Warmerdam. "Increased use of less toxic materials shows that we are moving in the right direction."

            As in previous years, most farm pesticide use occurred in the San Joaquin Valley, the nation's No. 1 agricultural area. Fresno, Kern, Tulare, San Joaquin, and Madera counties had the highest use, as measured in pounds. Other indicators summarized by DPR include the number of applications made and cumulative acreage treated, statewide and by county.

            Pesticide use varies from year to year based on many factors, including types of crops, economics, acreage planted, and other factors - -  most notably weather. A cool, wet spring in 2005 promoted fungus and other diseases in crops such as grapes, requiring more intensive pest management. 

            Some details from the 2005 DPR pesticide use summary:

            As measured in pounds, the most used pesticides were sulfur, petroleum oils, metam-sodium, 1,3-dichloropropene (1,3-D), and mineral oil.  Sulfur use increased by 7.3 million pounds (13 percent) and was the most highly used pesticide in 2005, both in pounds applied and acres treated.  By pounds, sulfur accounted for 32 percent of all reported pesticide use. Sulfur is a natural fungicide favored by both conventional and organic farmers.

            Fumigant chemicals decreased in pounds applied from 2004 to 2005 (1 million pounds, 2.5 percent) and decreased in cumulative acres treated (54,000 acres, 14 percent).  Use of about half of the major fumigants decreased in pounds but nearly all major fumigants decreased in acres treated.

            Pounds of reduced-risk pesticides increased by 630,000 pounds applied (60 percent) and by 2.4 million acres treated (39 percent).

            Crops that showed an overall increase in pesticide pounds applied from 2004 to 2005 included wine grapes (6 million pounds), oranges (2.7 million pounds), raisin and table grapes (1.8 million pounds), walnuts (1.2 million pounds), and almonds (1 million pounds).  Major crops or sites with decreased pounds applied included rice (1.5 million pounds), fresh tomatoes (700,000 pounds), strawberries (420,000 pounds), and lemons (370,000 pounds).

            For several years, DPR annual pesticide use summaries have included various toxic categories. The statistical summaries for these categories are not risk indicators. DPR uses the data to support regulatory activities to enhance public safety and environmental protection. Some notable changes from 2004 to 2005:

            Pounds of all the higher risk pesticide categories, except for toxic air contaminants, decreased and use of all the lower risk pesticides increased. Acres treated with carcinogens and organophosphates increased, mostly because of increased use of the fungicides mancozeb and maneb and the insecticide chlorpyrifos.

            Chemicals classified as reproductive toxins decreased in pounds applied from 2004 to 2005 (2.1 million pounds or 8.8 percent) and decreased in cumulative acres treated (88,000 acres or 4.1 percent).

            Pounds of insecticide organophosphate and carbamate chemicals, which include compounds of high regulatory concern, continued to decline as they have for nearly every year since 1995.

            Chemicals categorized as toxic air contaminants, another group of pesticides of regulatory concern, remained nearly the same as in 2005 while cumulative acres treated increased by 220,000 (6.1 percent).

Weed of the Month

***************************************************

New Newsletter Section (11/17/06)

            Locals often report weedy plants to me and there are weeds I would like to remind you about.  Therefore, I am adding a new occasional feature to my monthly newsletter – Weed of the Month.  I am far from an expert, so let me know and don’t hold me responsible, when I make mistakes or omissions.  All botanists and concerned locals out there are invited to submit a story or report a weedy plant to me.  I intend for the stories to be timely, i.e. about a weed in flower, presenting a new or incipient discovery, currently in the news, or needing more attention.  Stories will usually be about noxious or invasive weeds.  (My first Weed of the Month is an exception.)  I hope you find the new feature useful. – dc

 

Oxalis latifolia (10/9/06)

            Don Tate, a botanically astute local citizen, reported the presence of Oxalis latifolia (Oxalidaceae) growing quite densely in celery fields and sparsely in the ditch nearby in Lompoc this past September.  We, (i.e. Mike Champion, Agricultural Commissioner biologist), noticed this weed, 5 or 6 years ago, growing in an asparagus field, which has since been disced.  It has also been spotted in Carpinteria, growing in an Avocado orchard.  Routine maintenance of the orchard apparently eliminated the infestation.  

            I believe O.latifolia is relatively uncommon as a weed in Santa Barbara County.  Let me know if you think it is a common weed.  It is sold as an ornamental.  Looking very similar to O. cornicluata and O. pes-caprae, (Bermuda buttercup), O. latifolia is a pretty plant with pink flowers above shamrock shaped foliage.  Click here for pictures.  The horticulturist that submitted the pictures notes that it is an “easy to grow bulb; nice in containers and window boxes…  Can be invasive in warm zones."  It is not listed in Clifton Smith’s, A Flora of the Santa Barbara Region.  The Jepson Manual of Higher Plants lists the distribution as NCo, CCo, SCoRo and native to NM (New Mexico), and Mexico and as a weed of n SCoR (Salinas Valley).  The SCoRo designation includes Santa Barbara County.  Jepson’s does not give it a common name.  Common names for this plant include broadleaf wood sorrel, fishtail Oxalis, or Mexican Oxalis.  

            O. latifolia is not designated Cal-IPC invasive or CDFA noxious.  Apparently it is declared a secondary weed in Tasmania.  An Australian origin website I found considers it a major garden weed in most areas, extremely difficult to control once well established, and may cause oxalate poisoning in livestock.  Perhaps, while pretty (to some), it is a plant worth watching out for.
