We have had this problem for five years, and would appreciate any suggestions you may have. Your question concerning dodder was given to Tom Lanini , Extension Weed Ecologist , he has been working on dodder for the past 10 years. 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.
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. We are involved in a modest restoration project along a stream and nature trail that is part of our 33 acre site. Please let us know if there is a consensus as to the best method for doing this. Thank you for your attention.
