Antibiotische stoffen als fungicide tegen cercospora nicotianae op tabak

With a summary: Antibiotics as fungicides against Cercospora nicotianae on tobacco

  • P. A. van der Laan


Several fungus extracts containing antibiotics were tested for fungistatic activity onCercospora nicotianae, causing the “frog-eye”-disease of tobacco in the tropics.

The activity of extracts with actinomycin, streptomycin and viridin appeared very weak; an extract containing streptothricin was a little more promising; the pure clavacin is fungistatic againstCercospora at the concentration of 1 to 50.000, but burns tobacco-leaves already at 1 to 25.000. Best results gave gliotoxine extracts fromTrichoderma viride, strain 211 ofBrian. This antibiotic does not burn tobacco leaves and has a highly fungistatic and fungicidal action.
