As the webmaster of the Parasitic Plant Connection, one of the most frequent inquiries I receive from the general public concerns controlling dodder. I am not an agronomist or plant pathologist, therefore I can only provide you information (Table 11.3) I have about chemical control of Cuscuta derived from a chapter on that topic in the following book:
Eplee, R. E. and R. Norris. 1995. Control of parasitic weeds. In M. C. Press and
J. D. Graves [eds.], Parasitic Plants, 256-278 Chapman and Hall, London.
|Soil applied (for various hosts)||chlorpropham|
|alfalfa||DCPA and pronamide|
|chickpea, sugar beet, cranberry||pronamide|
|alfalfa||paraquat, diquat, dinoseb, DNOC, glyphosate|
|host denial||diuron, methribuzin, simazine, terbacil|
Before applying any herbicides, I strongly suggest you get a copy of this book and read this chapter. The original table (11.3) contains bibliographic references to each of these host/herbicide combinations. I also think there are some good web sites to check out for control of dodder such as:
http://www.dowelanco.com/western/Treflan_Dodder.htm. This site is specific to California.
