Very nice presentation of management with pre-plant fungicidal dips of anthracnose given by Gerald Holmes of CalPoly of work he did together with Jim Adaskaveg, Doug Gubler, Stacy Haack, Helga Foerster and Kelly Ivors did earlier this year.
Look at the presentation, it's very well done. The upshot (copied directly from the concluding slide) is as follows:
1. Actinovate had NO efficacy on anthracnose in the conditions of this study.
2. Azoxystrobin (Abound) is highly effective in controlling Colletotrichum if the strain is sensitive, but not effective if the strain is resistant.
3. Switch is highly effective as a dip in controlling Colletotrichum in all the cases of this study. No phytotoxicity was detected in the conditions of this study (ie 4 minute dip with agitation, followed by 5 to 10 minutes drip drain).
4. Two new compounds, EXP-13 and Syngenta-2 (not registered yet) were found with high efficacy.

Review the ppt, there seem to be some promise with the numbered compound from Syngenta which is a biological.
One of the things I'm glad this study covered was the use of Actinovate, which as you know is organic and was being promoted in some circles as being effective. Given my experience with this product, I felt this enthusiasm was premature and I am glad to see my sentiments proven here in this work.
You always know I am open to new ideas for testing. If you have something interesting, you always know where to find me.
