Maton]}, volume={35}, url={https://informaticsjournals.com/index.php/jbc/article/view/26772}, DOI={10.18311/jbc/2021/26772}, abstractNote={&lt;p&gt; Investigations were made to study the effects of three nemato-pathogenic fungi&lt;em&gt; viz.&lt;/em&gt; &lt;em&gt;Purpureocillium lilacinum&lt;/em&gt;, &lt;em&gt;P. lilacinum&lt;/em&gt; + neem cake, &lt;em&gt;Pochonia chlamydosporia&lt;/em&gt; and&lt;em&gt; Trichoderma&lt;/em&gt; sp. as well as two synthetic insecticides (cartap hydrochloride and carbosulfan) against the Root-knot Nematodes (RKN) of cardamom at the farmers’ fields in three locations of Idukki district, Kerala, India during 2016- 2019. Results revealed that the combined application of &lt;em&gt;P. lilacinum&lt;/em&gt; with neem cake gave maximum reduction of typical symptoms of infestation like the leaf narrowing (6.42%) and root knot formation (1.32 nos.) followed by &lt;em&gt;P. chlamydosporia&lt;/em&gt; with 8.04% narrowed leaves and 1.83 root knots. The application of &lt;em&gt;P. lilacinum&lt;/em&gt; and neem cake in combination (0.82 kg/plant and 2.99) followed by&lt;em&gt; P. chlamydosporia&lt;/em&gt; (0.71 kg/plant and 2.71 recorded highest yield and Benefit Cost Ratio, respectively). Bio-control agents are therefore efficient and environmentally safer for managing the RKN in cardamom. Future studies can be directed to focus on the compatibility and efficiency enhancement of these bio-agents with organic amendments.&lt;/p&gt;}, number={2}, journal={Journal of Biological Control}, author={T., Sathyan and M.
