When fruit is grown for the trade this is absolutely necessary. For home orchards the later sprays may be omitted. The first two summer sprays, however, must be applied if even fair fruit is expected. For the best results in the commercial orchard it is often desirable to give later or more frequent applications than those outlined below. This schedule is arranged to meet average conditions. Spray Schedule Dormant Spray.--Applied as a sanitary measure and particularly for the control of scale insects. Material used--Concentrated limesulfur diluted to test five degrees Baume which would ordinarily mean six gallons of lime-sulfur to 50 gallons of water.
