So what did we see?

applying conventional treatments.
Now, the organic treatments: When compared to the copper trial, milk whey showed a slight decrease in infected leaves, number of spots, and coverage area of rust. However, these decreases are relatively small and could still be attributed to random error. Sodium Bicarbonate showed a decrease in all areas when compared to copper. However, these decreases are also relatively small and could also still be attributed to random error.
And finally, the madrifol treatment: Of all of the areas, this treatment is perhaps the most confusing. Upon initial analysis, it appears that there was a large increase in the number of rust spots in this plot. However, it was observed that two of the five treated plants appeared to have decreased rust incidence, while the other three showed significant increases in rust severity.

treatments to the plants.
We separated out the two trees that have normal spacing and found a decrease in both coverage and spot size, suggesting that madrifol may actually interrupt the development of rust spots, but only with proper spacing and pruning.
We are continuing to apply both organic and conventional treatments on the test farm. We will take the next sampling in another 30 days, and we will keep you updated on the progress of the experiment.
