EXPERIMENT STATION BULLETINS. 



329- 



PLUMS -(PrwnMs). 



Whether caused by the copper sulphate spray applied in April to plume 

 in common with all other fruits, or from other cause, the plum trees have 

 been notably exempt from the attacks of fungus, except that there was a 

 very considerable loss of fruit from rot {Monilia fructigena) during the 

 month of September, this being its first appearance upon the plum upon 

 the station grounds, although it had been slightly noticeable, a year earlier, 

 upon some of the earlier peaches. 



The crescent of the curculio was observed, and the jarring process com- 

 menced as early as May 14, finding a good many insects. The jarring wa& 

 continued, except during high winds, till June 12, when the insect had 

 disappeared. 



The first rose chafer (Macrorfac/^/^ws suhspinosus) was discovered on May 

 27, and a few as late as June 5, after which date no more were seen. A few 

 were caught upon roses, though they have been conspicuous this year by 

 their absence. 



This year's crop of plums was comparatively light, due doubtless to the 

 excessive crop of last season.
