If you want to do this per product just delete the contents of the Description box in the Information tab when editing a product.

 

 

If you want to remove this information from all products then you'll need to delete the following lines from the product.tpl file in your theme's directory:

{if isset($product) && $product->description}                         
    <!-- More info -->                                                
    <section class="page-product-box">                                
        <h3 class="page-product-heading">{l s='More info'}</h3>       
        <!-- full description -->                                     
        <div  class="rte">{$product->description}</div>               
     </section>                                                        
    <!--end  More info -->                                            
{/if}

If you delete these lines, be sure to delete the smarty cache etc...

In that case just delete the single line:

<h3 class="page-product-heading">{l s='More info'}</h3>
