Peach. — For this fruit use only one-half the amount of bluestone and 

 one-half the quantity of Paris green that is used for the regular formula. 

 Arsenate of lead is, however, much the most effective and safest poison 

 for use on peach and plum, and should be used at rate of 3 pounds to 50 

 gallons. Late peaches usually require four sprayings for best results, 

 as follows : 



1. Late February or early March, before buds burst. 



2. About a week after blossoms fall. 



3. Ten days to two weeks after second spraying. 



4. When fruit is nearly grown, but before coloring begins and before 

 rot appears. 



Very early varieties of peaches may be sufficiently protected by three 

 sprayings, or perhaps with only two. 



These treatments will, to considerable extent, lessen the ravages of the 

 Curculio, which makes the worm at the pit ; also, leaf curl and the brown 

 rot of the fruit. 



Plum. — Same remarks as for peach. 



Cherry. — Same general enemies as the peach, but usually not neces- 

 sary to spray, and results are not usually satisfactory. _ 



Conclusion. — It may not every year be necessary to give all the treat- 

 ments which we have outlined, but, as we cannot tell what insects are 

 going to be present in any particular year, it is best to have a regular 

 plan of treatment in mind, to be followed as closely as circumstances 

 will permit. Sometimes there will come seasons when the spraying fails 

 to do what is desired of it ; but taking it all in all and year after year, 

 the man who follows the methods here outlined will soon find that he is 

 paid for his trouble and expense many times over. 



Finally it should be said that success in spraying with the Bordeaux 

 Mixture (poisoned) depends fully as much on its being done thoroughly 

 and at the right times as on the number of times that the trees are 

 sprayed. Some good growers never attempt more than two sprayings 

 and do well. Time and again growers have told me of cases where only 

 one spraying with apples (given just after the blossoms fall) worked 

 wonders in securing better fruit. Of all sprayings with apples, the one 

 which comes soon after the blossoms shed is the most important, and 

 must not be neglected. 



THE LIME-SULPHUR WASH. 



This is the material now mostly relied upon for controlling the San 

 Jose Scale, and it has proven so effectual in all parts of this State that 

 when one once finds that his trees are infested and knows how to prepare 

 this wash, there is no real necessity for another tree being lost from the 

 scale. When the ingredients are properly boiled together and the wash 

 then sprayed (or applied by hand with mop or brush) on the trees, so 

 as to thoroughly treat all the branches and twigs, it is fatal to every 

 scale that is wetted by it. It cannot, however, be relied upon to exter- 

 minate the San Jose Scale, for it is impracticable to make any appli- 

 cation so thorough as to reach all of the tiny scales. It is so effective, 

 however, that one thorough treatment late each winter is sufficient to 

 keep the trees in good condition. Trees that are very badly infested
