Thats all I do in my gardens, using a variety of mulching ingredients I collect from neighborhoods putting out yard waste, which I see as gold. Seriously. We also used Nutri-Cote fertilizer. Every episode Ive watched (scores of them) contains a bare minimum of one absolutely crucial error in how a given test should be executed and even what a given test would actually demonstrate. I am a great believer in mixing plantings because what one plant takes out another could put back and thereby prevent a build up of particular pathogens and maintain a balance of microbial activity and nutrients in the soil (working in harmony with nature). Just tabulating the data from the replies here, it looks like corn meal works every time. From the abstract: A survey of different batches of corn meal for the inhibition of their fungal flora by propionic acid, benzoic acid, potassium sorbate, and Mold-X, a commercial inhibitor composed of four organic acids, revealed differences in inhibition so extreme that the batches of corn meal could be categorized as sensitive or resistant to the effects of an inhibitor.. However, high-value residential oaks may be treated with an injected registered chemical that protects individual trees. Applying a wax as a wound dressing may keep the oak wilt away, but as soon as the wax wears off, the tree will be vulnerable to disease with no ability to protect itself. Ill do it!

Nevertheless, were informed that a gardening personality has continued the study and finds cornmeal effective on most everything from turf grass to black spot on roses. This is directly refuted by Dr. Jerry Parsons, who by happy coincidence is an extension faculty specialist at Texas A&M. The next year (2015) a June inspection discovered all five trees with symptomatic leaves and we recommended re-treatment. So, why not purchase some and give it a try. Success with therapeutic treatments is better when less infection is present. Jay, there are a variety of recipes for culturing Trichoderma spp. is up proponents to demonstrate, conclusively, that it works. In 2017, the client decided to do the treatment themselves and save the $125. On a side note, I do wonder about using corn starch or even corn flour for its phosphorous content. In both of the studies, Trichoderma suppressed the disease issues.

I very much appreciate that you have taken up this topic. Even the most efficient N-supplying composts, cover crops, or other organic N sources do not release appreciable N to a subsequent crop beyond 6 to 8 weeks from incorporation, and this burst of early N may not synchronize with N requirements for many vegetable crops. I have no skin in this game; I just ran across your rant when I was doing agricultural research. THAT is how science is done.
