250 FRUIT INSECTS 



Peaches, 



On peaches the direct injury caused by the curculios is 

 greatly augmented by the brown rot which is distributed by 

 the. beetles and which gains entrance to the fruit through 

 their punctures. As far as spraying is concerned, the two 

 problems are considered as one, antl the following system has 

 been devised for the control of both, based on extensive ex- 

 periments in Georgia and Missouri. 



The first application should be made just as the calyxes 

 (shucks) are shedding, using 2 pounds arsenate of lead to 50 

 gallons of water, to which is added the milk of hme made from 

 slaking 2 pounds of stone lime. As this is too early for brown 

 rot, the fungicide is not used. 



The second application is made about three weeks later, using 

 2 pounds of arsenate of lead in 50 gallons of the self-boiled lime- 

 sulfur (8-8-50). 



A third application should be made about one month before 

 the ripening of the fruit, using self -boiled lime-sulfur only. 

 The poison is omitted, because experience has shown that it is 

 very unsafe to spray peaches more than twice with arsenate of 

 lead. 



Apples. 



In spraying apples there is practically no danger of injury 

 to the fruit or foliage by repeated applications of arsenate 

 of lead. The two sprayings usually given for the codlin- 

 moth, just after the petals fall and three weeks later, are 

 of considerable value in controlling the curculio, but where 

 the infestation is severe, additional applications will be found 

 necessary. The spray often given for the second brood of the 

 codlin-moth nine or ten weeks after the petals fall will help 

 to control the pest, and in the South it is sometimes advisable 

 to repeat the application two or three weeks later. To get the 

 best results the spraying must be done in a very thorough 

 manner, using a fine nozzle and high pressure in order to keep
