Abstract

Castor is an important non-edible oilseed crop and plays a vital role in Indian economy. Castor is affected by several biotic and abiotic factors. Among plant parasitic nematode, reniform nematode (Rotylenchulus reniformis) is the most widely distributed and the destructive nematode. It is considered as one of the major limiting factors in the production of castor. Owing to adverse impacts of chemicals on human health, there is need to evolve ecofriendly methods of nematode management. Biological nematode control in relation to crop production system is a subject of considerable current interest because of a perceived urgency to develop and adopt safe, economic and efficient method for managing nematode pest of crops. During present investigation, Farm Yard Manure (FYM) enriched with bio-agents viz., Glomus fasciculatum, Trichoderma harzianum and Beauveria bassiana were tested as soil treatment at 2.5, 5 and 10 g/plant for the management of R. reniformis on castor. Results showed that T. harzianum at 10 g/plant was found most effective followed by Glomus fasciculatum at 10 g/plant and Beauveria bassiana at 10 g/plant which significantly enhanced the plant growth parameters of castor and also reduced the nematode multiplication factors. Bioagents T.harzianum reduce the density of reniform nematode (31.16-66.18%) and enhance the plant growth (30.23-94.70%)

Keywords

Glomus fasciculatum, Bio-agents, Castor, Rotylenchulus reniformis, Trichoderma harzianum, Beauveria bassiana and FYM

Conclusion

Present investigation focused on the use of bio-agents and organic amendments in sustainable agriculture system and opens up vistas for the use of bionematicides which are promising as well as ecologically sound and safe. Hence, efforts in discovering new non-chemical or eco-friendly strategies for nematode management should be continued to overcome future challenges.
