The efficiency of the one-spray and demonstration treatments in 
preventing worminess is shown in condensed form in Table XII. 
Here it will be seen that the one-spray method was nearly as effective 
as the demonstration in preventing calyx entrance, but gave little 
benefit in regard to side infestation.
