early applications, are nuich less apt to show injur}' from 

 later sprayings. 



The application Just after the blossoms fall is usually 

 the one zchich i^ires clean fruit. All the fruits that are in- 

 fected before the blossoms open, later fall from the trees ; 

 therefore only clean fruits will be left to be protected by 

 later applications. This spraying just after blossoms drop 

 is the most important of all. Xever omit it. Spray just 

 before rain periods, not after them. Watch your zveather 

 maps. If YOU recall that the scab spores are scattered, and 

 infect the fruit and leaves only during rather extended rain 

 periods, you will at once, see the logic of having the spray 

 mixture on the trees ahead of the rain. Don't let the 

 notion that it will "wash off" deter you. If it is once dry 

 little will wash oft'. The nearer you can come to getting 

 it on just before the rains the better, for the more new 

 growth you will thus protect. The development of the 

 buds ami fruit and the character of the zvcather must be your 

 guide in spraying for apple scab. 



The number of sprayings to be made will depend much 

 on the season. Nearly all good growers make an early or 

 dormant spray. This is for insects, blister mite, scale, etc. 

 It has no effect on the control of the apple scab. Some 

 seasons it may be advisable to make another application 

 following the one made just after the blossoms fall. This 

 is usually not profitable so far as scab control is concerned. 

 A late application the latter part of July or first of August 

 is in some seasons highly beneficial and profitable in pre- 

 venting a late infection of the fruit, which may appear at 

 packing time or after the fruit goes into storage. 



Lime-Sulphur. We may now consider some of the 

 more important points brought out in the past two seasons' 

 investigations w^ith lime-sulphur as a substitute for Bor- 

 deaux mixture. Not onlx- in our own, but the experiments 

 of others in different parts of the United States have shown 

 that lime-sulphur is equally effective icitli and safer than
