EFFECT OF INORGANIC FERTILIZERS ON THE EFFICACY OF PAECILOMYCES LILACINUS IN THE CONTROL OF SOIL BORNE ROOT INFECTING FUNGI ON MUNG BEAN

SHAHNAZ DAWAR AND A. GHAFFAR

Abstract: Use of inorganic fertilizers viz., urea, NPK, DAP and superphosphate on the efficacy of Paecilomyces lilacinus inoculum multiplied on rice grain showed that the infection of Fusarium spp., significantly reduced in mung bean plants where soil was treated with P. lilacinus alone, urea or NPK at 0 days. Seed sown after 10 days of treatment showed complete control of Fusarium infection where soil was amended with P. lilacinus + DAP. Infection of Macrophomina phaseolina was completely controlled where seeds were sown after 40 days of treatment in soil treated with urea alone and P. lilacinus mixed with urea. Similarly, complete suppression of Rhizoctonia solani infection was observed where soil was treated with superphosphate, NPK alone or P. lilacinus used with superphosphate, NPK, urea or DAP after 40 days of soil treatment.
