I have a small family hay operation (alfalfa/oats) in northern CA and your information on varieties, herbicides, application rates has been most helpfull. I have also used fly ash as a soil amendment (Nakamura/Forero) and use reclaimed water from a local treatment plant.

Any good suggestions on how to get rid of "NUT GRASS" (CYPERUS ROTUNDUS) from my lawn? mahalo, giovanni paciello
---------------------
Cyperus rotundus is commonly known as purple nutsedge. There is a link to the Nutsedge Pest Note on the Weed Information page. Under the management section it recommends:
"If nutsedge is found in small patches in turf, it may be best to dig out the patch to about 8 inches deep, refill, and then seed or sod the patch."
Please read the entire document for more information.

There is a link to Crop Data Management Systems on the Useful Links page - a great site for MSDS information.

What would you suggest we use to eliminate a dodder infestation? We have had this problem for five years, and would appreciate any suggestions you may have. Thanks much Deb
---------------------
Your question concerning dodder was given to Tom Lanini, Extension Weed Ecologist, he has been working on dodder for the past 10 years.

The first question is what is the dodder growing on (what is the host plant)? The options that exist are to plant a non-host crop, plant before or after the dodder emergence period (most dodder emerges between Mid-March and Mid-May), treat with a herbicide (herbicide choice would depend on the crop), or remove the dodder by hand. Once we know what crop(s) the dodder is attacking, we will elaborate on the options.

Good things here. I am looking for the weed susceptiblity charts by crop. I've checked the IPM site and they don't have them for all the crops. Apples, Stone Fruit and some other crops don't have any. Grapes have a nice one. Why don't the other crops have charts like that? I know I've seen the charts in UCCE newsletters but can't find them on the sites anywhere. This would be a good place to have them.

There is a herbicide susceptibility chart available at the bottom of the Weed Information page.

I am a volunteer with the Conejo Valley Botanic Garden in Thousand Oaks (Ventura County), California. We are involved in a modest restoration project along a stream and nature trail that is part of our 33 acre site. With funds from the Department of Public Works and labor from the California Conservation Corps we have spent two weeks removing Washingtonia filifera and Canariensis palms from the riparian areas; now we will devote a week to removing Cortaderia species, the pampas grasses. Please let us know if there is a consensus as to the best method for doing this. We will have intensive labor now, and perhaps once more; then we will depend on our volunteers for followup. Thank you for your attention.

Would like any information and references on the control of perennial pepperweed. This weed is quite invasive in our water treatment plant in Martinez, CA. We are interested in any methods to eradicate including chemical ones.
---------------------
Please check the The Nature Conservancy web page for information about perennial pepperweed. There are two documents on this page which should be useful to you. If you need more information you may contact the author, Mark Renz, at mjrenz@ucdavis.edu.

I enjoyed viewing this site. Please put me on your mailing list if one exist. What are the "safest" herbicides for aquatic weed control? I live in a developing tropical country where aquatic weeds are a major problem. Some of these include several species of Eichhornia (E. crassipes, E. paniculata, E. diversifolia etc.), Hydrocleys nymphoides, Pistia stratiotes, Salavinia auriculata and many grasses. These weeds have caused tremendous problems in drainage and irrigation, especially for rice and sugar cane production. Do you have any suggestions/ recommendations? Ramesh
---------------------
If you go to the Aquatic Weeds web site, you will find a list of aquatic herbicides approved by the US EPA for aquatic weed control, along with susceptibility ratings for species common in the U.S. Some of the species you listed are on this list.

I have a grower with a Equisetum species infesting a roadway in a vineyard. What could be used to control the weed as it has spread up and down the road way and he does not want it to spread into the vineyard. The soil is a heavy clay and retains a lot of moisture into the summer. Any suggestions? Thanks.
---------------------
Several UC Weed Specialists provided the following responses:

-Equisetum will re-appear each year until they eliminate the wet soil situation. First provide drainage, then foliar glyphosate as label recommends (for two or three seasons) should provide control.

-Glyphosate is only partially effective at best. The best solution is to improve the drainage situation.

-I never was able to get adequate control, even after two years, with 2% glyphosate.

-check out this supplemental for the herbicide Manage: http://www.cdms.net/ldat/ld549000.pdf. Also, I have heard that chlorsulfuron (Telar) and diclobenil (Casoron) work too, but the main thing, as pointed out, is to keep at and try to modify the site to make it less hospitable for the weed. I doubt if any of the herbicides is a "one-shot cure-all" for the problem.

I have had this annoying weed in my back yard lawn for several years and could not get rid of it. I tried Roundup on it several times with little or no success. I have been lately pulling it up by following the stems from root to root. I was thrilled to identify this today on your web page as Bermuda Buttercup and find my hand weeding seems to be the only way to control this. It is hard as I have quite an infestation but I am controlling the spreading new growth. Thanks a million for the information. What a relief to know what it is.
---------------------
Thanks for letting us know this information is helpful!! Weed identification information can be found on the Weed Information page.

Is there any chemical that can be used in a residential yard to rid the yard of bermuda grass. I have a mostly fescule yard and I would like to keep it pure fescule.
---------------------
The following information was taken from the UC Pest Management Guideline for Bermuda Grass.

Selective Herbicides - Early spring is the best time to apply selective herbicides. Four herbicides that are safe to use near many ornamental plants (see labels for exact species) include sethoxydim (Grass Getter) and fluazifop (Grass-B-Gon, Ornamec), which are available for use by the home gardener, and clethodim (Envoy) and fenoxaprop (Acclaim), which are available for use by licensed pesticide applicators only. In cool season turfgrasses (annual and perennial ryegrasses, bentgrass, fine and tall fescues, and Kentucky bluegrass) triclopyr and/or fenoxaprop can be used by licensed applicators to suppress bermudagrass.

We have recently purchased a 120 acres within Los Padres National Forest and are inundated with Star Thistle and it is spreading to the adjoining forest lands. What is recommend for erradication without out use of herbicides? Thank you, Rose Creek Ranch

Yellow Starthistle information can be found on the Weed Information page. The document is available to view on the internet or download as a pdf for printing. It includes information for controling Yellow Starthistle by mowing, grazing or burning. We hope to have an extensive web page devoted to this plant in the near future.
