In comparison, a susceptible check, I979 was also evaluated. The feeding preference of &lt;em&gt;H. armigera &lt;/em&gt;larva was the least towards Varushanadu Local than I979 irrespective of the biofertilizer. Among the biofertilizers K-solubilizer treated plants were the least preferred than others. A trend was observed in both the free choice and confinement tests.&lt;span style=&quot;mso-spacerun: yes;&quot;&gt;Ã‚Â Ã‚Â  &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
