PLUMS 



For the protection of plums the same recommendation is made 

 as for peaches. The plums can be washed and all residue should be 

 removed before the fruit is eaten or delivered at market. 



CHERRIES 



In a normal year the cherry crop in the heavily infested area is 

 harvested before Japanese beetles have emerged in numbers large 

 enough to cause any great injury either to the trees or to the crop. 

 As spraying the trees just prior to harvesting the crop would result 

 in excessive spray residue on the fruit, the application should be 

 made just after the cherries are harvested. A second application 

 may be necessary two to three weeks later. Lead oleate coated lead 

 arsenate spray in the proportion of 9 pounds to 100 gallons of water 

 should be used. 



Where yellow leaf or leaf spot is present in an orchard, the usual 

 2y 2 gallons of commercial lime and sulphur concentrate solution to 

 100 gallons of water is recommended. TThere this spray is applied 

 immediately after the fruit has been harvested. 4 pounds of lead 

 arsenate and 4 pounds of flour should be added for control of the 

 Japanese beetle. This application should be repeated from two to 

 three weeks later. Lead oleate coated lead arsenate should not be 

 added to any spray mixture containing lime. 



GRAPES 



BEAEI^G VTXES 



Six pounds of lead arsenate. 4 pounds of flour, and 100 gallons of 

 water is recommended for the protection of bearing vines. As the 

 beetles do not feed on the berries, it is only necessary to spray the 

 leaves. The spray should be directed from the top down, using a 

 very fine mist and coating each leaf thoroughly. Care must be taken 

 not to force the spray up from below, as this might leave too much 

 spray deposit on the berries when harvested. A second application 

 should be made two to three weeks later in order to protect the new 

 growth that comes out after the first spraying: otherwise beetles will 

 accumulate upon it. and severe injury will result both to it and to 

 other portions of the vines in spite of the spray coating. 



YOrXG AXD rCOTBEABIXG VI^TES 



For the protection of young and nonbearing grapevines, 9 pounds 

 of lead oleate coated lead arsenate to 100 gallons of water should be 

 used, and the application repeated as often as necessary to protect 

 the new growth. 



TThere the practice is to use the 4-6-50 Bordeaux mixture on 

 grapes at about the time the beetle spray should be applied, the 

 lead arsenate in the formula for the protection of bearing vines is 

 added without the flour. Many varieties of grapes, such as Ives. 

 are often seriously burned by heavy applications of Bordeaux mix- 

 ture. In such cases it is suggested that the spray for Japanese 

 beetles be composed of 6 pounds of lead arsenate. 4 pounds of flour. 

 and 100 gallons of water.
