I found a few examples of bacterial plant disease forecasting including fire blight of fruit trees, bean bacterial diseases, onion xanthomonas. Is there any other bacterial disease control programs based on prediction of pathogen development?
Thanks to Ronald Gitaitis, he gave the first answer:
"Although it can be seedborne. P. stewartii is notorious for being transmitted by corn flea beetles. In fact there is an old time forecasting method that added the average daily temperatures for Dec-Feb and if it was above a certain threshold the prediction is for a bad year for stewart's wilt of corn because more flea beetles survive the winter."
Dear Alex
You can find the information of 10 forecasting models for Fire Blight of Pear and Apple in the website of The University of California Statewide IPM Program (UC IPM) :

Good luck
Dr Aghajani, thank you! I think there are two general models for bacterial diseases forecasting: the first based on vector development prediction, and the second - on weather before the potential outbreak of disease.
Japanese researchers used bacteriophage monitoring in water from rice paddy fields to predict outbreak of Xanthomonas oryzae. Do you think that such method can be applied for other bacterial pathogens?
It depends on the existence of bacteriophage for that bacterium. First of all, it must be checked.
It is possible to find bacteriophage specific for most of plant pathogenic bacteria present in environment (water, soil, plant surface). But, many plant disease outbreaks are associated with seed infection. I think of cereal diseases, because they cannot be predicted from level of seed contamination (P. atrofaciens, X. translucens/arboricola are often found on seeds), and grow first on and in plants without visual symptoms.
