The interaction between Pratylenchus coffeae and Pythium aphanidermatum and/or Rhizoctonia solani on chrysanthemum and the influence of farmyard manure (FYM) on it was studied under pot conditions. The disease caused by P. aphanidermatum or R. solani was significantly high at varying inoculum levels of Pratylenchus coffeae. The severiy further increased when nematode infected plants were inoculated with both the fungi together. Organic manuring also influenced the disease severity which was greatest in soils containing 200% organic manure. The nematode population significantly increased in presence of R. solani , decreased in presence of P. aphanidermatum and remained unaffected when both the fungi occurred together around the plants. The nematode population was greatly reduced in soils containing 200% organic manure.
