Efficacy of Paecilomyces lilacinus (1% W.P.) against Meloidogyne incognita on tomato in different agro-climatic regions in India

Bio-efficacy of a bio-nematicide, IIHR -Paecilomyces lilacinus (Purpureocillium lavendulum Luangsa-Ard) was evaluated for the management of Meloidogyne incognita (Chitw.) on tomato (Solanum lycopersicum L.) at Indian Institute of Horticultural Research, Bengaluru and C S Azad University of Agriculture and Technology, Kanpur, Uttar Pradesh, India. The trials were conducted in two different agro-climatic regions using Farm Yard Manure (FYM) enriched with P. lilacinus (1%) W.P. Standardized optimum dose for the seed treatment with P. lilacinus (1%) W.P. Seed treatment at the rate of 20g/kg, nursery bed treatment at the rate of 50g P. lilacinus/m² and application of FYM (5 tons) enriched with 5kg of P. lilacinus/ha proved to be significantly effective in the management of M. incognita and these treatments increased the yield of tomato significantly. The results of these trials revealed the potential of this bio-nematicide in the management of M. incognita on tomato in two different agro-climatic regions.
