Abstract

 

Coriander (Coriandrum sativum L) is severely affected by the most common and wide spread stem gall disease caused by fungus (Protomyces macrosporous Unger). The efficacy of fungicides and bio- agents against this disease were studied. The treatment of soil solarization, soil application of T.viride (1kg/plot) and foliar spray with tridemorph (Calixin 0.1%) after 60 days after sowing (DAS), seed treatment and a foliar spray with tridemorph (Calixin 0.1%) or carbendazim (Bavistin 0.1%) applied at 60 DAS were equally effective in reducing the disease intensity and in improving yield. The bacterial antagonists viz, Pseudomonas fluorescens or Bacillus subtilis applied as seed treatment and a foliar spray at 60 DAS, and wettable sulphur (0.2 %) at 60 DAS were found less effective in controlling the disease.

 

Key words: Stem gall, Protomyces macrosporous, integrated disease management
