title: Studies on certain aspects of chemical control of bacterial stalk rot disease of maize.
abstract: Sandoz seed dressing 6335 showing high efficacy in checking the growth of the maize stalk rot pathogen Erwinia carotovora f. sp. zeae Sabet in culture. Brestan, Antracol, Difolatan, Aratan, Duter, Ceresan wet, Flit-406, Cuman, Blitox-50, Streptocycline, Agrimycin, Terramycin, Actidione, Aureomycin, Chloromycetin, Penicillin G, and Streptomycin were moderately effective. The rest of the 35 chemicals was negligible in its influence. 15 different chemicals, namely Agrimycin, Streptocycline, Chloromycetin, Sodium penicillin G, Actidione, Terramycin, Aureomycin, Sandoz seed dressing 6335, Antracol, Aratan, Blitox-50, Diflotan-80, Ceresan wet, Cuman and Brestan 60 could also control the disease, but only when the plants were treated in vivo immediately after inoculation. They could not show any effectiveness, however, after 24, 48, and 72 hours of inoculation, showing their failure to control, once the infection has taken place by the pathogen.
