POWDERY SCAB PATHOGEN EXPERIMENT
      Ever hear of spongospora subterranea? Most people know it as "powdery scab,"  a troublesome fungal infestation that has been popping up in potato fields, greatly worrying potato farmers.  Indeed, powdery scab pathogen is showing up in essentially every potato crop area in the world. Here are the results of the experiment conducted with AgriCultures...

                                       PHASE I:  GREENHOUSE EXPERIMENT 
      
Under the direction of  Dr. Richard Zink, Colorado State University, Cooperative Extension, San Luis Valley Research Center, a controlled greenhouse experiment with ACI Bioremediation (formerly AgriCultures International) began to determine AgriCultures' possible effectiveness in eliminating this disease. See newspaper article about this experiment.  
        Several months after the experiment began, Dr. Zink personally inspected all of the containers. He found that the two containers without the cultures yielded an entire crop of potatoes diseased with powdery scab   Of the six containers inoculated with the six different strains of AgriCultures, two containers yielded an entire crop of potatoes that were deemed by Dr. Zink to be completely free of the powdery scab disease.
                                          
PHASE II:  IN-FIELD EXPERIMENT   
       This experiment was overseen, monitored and the results evaluated by the Staff members of the Colorado State University Agricultural Extension Program, located in Center, Colorado.  One particular field in the San Luis Valley had been chosen for this particular experiment, since it had produced a pathogen affected diseased potato crop for several seasons prior.  Wet weather late in the growing season seems to trigger the pathogen spores present, thereby infecting the potato tubers. 
       Twelve rows within a much larger acreage also planted with potatoes were used for this experiment, with each row about fourteen feet in length, and only one row (#12) assigned for the use of AgriCultures. All rows were planted by Colorado State University, Agricultural Extension staff, who purposely planted powdery scab pathogen-diseased seed potatoes into the affected soils, then inoculated only row #12 with AgriCultures. 
      At harvest time, in early September, the row inoculated with AgriCultures produced a bumper crop of very large healthy potato tubers.  Since other areas of this large acreage field crop were highly variable in the presence or absence of the diseased tubers, no solid scientific conclusions could be drawn. One staff member called it a “mixed bag”, since there were some areas within this same field where the powdery scab had not been triggered. “Luck of the Irish” mumbled a CSU staff member, as many shook their heads in disbelief due to the outcome of the long awaited results of this experiment. 
        Officially, the field experiment was considered  “inconclusive” by CSU because of the mixed results in the field outside of the AgriCultures row. 
        However, due to the success of the AgriCultures in-house experiment conducted this past spring, wherein two of the six chosen strains of AgriCultures produced a completely healthy crop, void of any sign of the disease, coupled with the results of the in-field crop experiment within the row #12 inoculated with AgriCultures, it is possible to mark these results in favor of AgriCultures.
