Abstract

To determine the effect of different bio agents i.e. Pseudomonas fluorescens, Trichoderma viride on plant growth parameters and the effect of different treatments on root knot nematode multiplication in Black gram (Vigna mungo L.). The Completely Randomized Design (CRD) was used to set up a pot culture experiment, which was then replicated three times with ten different treatments. The results showed that all of the treatments improved plant growth parameters while reducing root knot nematode proliferation when compared to the control group. T8-(T2+T4) outperformed the other treatments by increasing plant height, root length, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, and decreasing the number of galls, number of egg masses, total nematode population in 200 cc of soil, and total nematode population in soil and root. Followed by T9 (carbofuran treatment @ 10g/m2) and T5-(T1+T3) (Seed and soil treatment of Trichoderma viride @ 10g/ka and 20g/m2 respectively

Keywords

Root Knot Nematode, Black gram, Pseudomonas fluorescens, Trichoderma viride.

Conclusion

Because of the rising nematode pest resistance problem and the high demand for safe and high-quality food items, biocontrol will continue to expand in the future. By lowering the burden of poisonous nematicides and associated adverse effects, bioagents can aid in the formation of population regulating processes for major nematode pests. It frequently involves biocontrol chemicals that can interact with either a plant or plant nematodes to inhibit nematode growth and restrict the nematode's harmful impact on the host plant. Plant development and yield are aided by bioagents. Finally, studies focused solely on the bioagents would yield useful knowledge for better nematode disease control while avoiding injury to other biosystems. However, there will be a number of obstacles to overcome.
