Each February, VineSmith, Inc. publishes the Eastern United States Grape Fungicide Guide. This "at-a-glance" color-coded poster helps vineyard managers plan an effective and economical grape disease management program. The first part of the guide -- the Disease Development Calendar -- illustrates, in color, critical control periods for each of the five major grape diseases. The Application Restrictions section shows, in a comparative format, all limitations for the use of each fungicide currently registered for use on winegrapes. The Control Options Calendar illustrates the efficacy, spray interval, rate, and cost of each fungicide.
