When &lt;em&gt;Phytophthora&lt;/em&gt; infested soil was supplemented with &lt;em&gt;Trichoderma&lt;/em&gt;, a disease reduction of 27.5-63.75% was noticed in 20 days application compared to soil without &lt;em&gt;Trichoderma&lt;/em&gt; supplement. Hence for the biological control of &lt;em&gt;P. capsici&lt;/em&gt; in black pepper system, the pH of the soil has to be maintained after at 4.5-6.0 in order to facilitate the growth and proliferation of &lt;em&gt;Trichoderma&lt;/em&gt; which in turn will reduce the population of &lt;em&gt;Phytophthora&lt;/em&gt;.}, number={2}, journal={Journal of Biological Control}, author={Suseela Bhai, R. and Raj, Sithara and Kumar, A.}, year={2010}, month={Jun.}, pages={153–157} }
