Abolishment of Specific Toxicity of Host-Specific Toxin of Helminthosporium carbonum by Electrolytic Reduction.

The host-specific toxin produced by the plant pathogen, Helminthosporium carbonum Ullstrup is normally about 300 times as toxic for corn plants susceptible to the disease as it is for disease-resistant plants. Electrolytic reduction of the toxin destroys this specificity, rendering the material no more toxic for disease susceptible plants than for disease resistant ones.
