dc.description.abstractThe sensitivity of two systemic fungicides, Ridomil and Aliette to Phytophthora palmivora was tested by poison bait technique. Ridomil at 100 and 200 ppm showed 80% and 86% inhibition respectively, in the radial growth of the fungus and complete inhibition at 300 ppm. Aliette showed 22 % and 50 % inhibition of the fungus at 509 and 1000 ppm respectively and growth was absent at 1500 ppm. The systemic activity of the fungicides was evaluated by measuring the lesion diameter on the% inoculated leaves of black pepper pretreated with fungicides. Ridomil-treated leaves showed no lesion at 500 and 1000 ppm whereas Aliette-treated leaves showed inhibition of the lesion development to the extent of 57% and 71% at 500 and 1000 ppm respectively.en_US
