In the discussion which followed Mr. Howard reported that "X. O. 

 Dust " — a patent combination of ground tobacco and some other sub-

Mr. Smith reported that he had found the same substance an excel-

EXPERIMENTS WITH REMEDIES FOR THE PLUM CURCULIO. 



Clakence M. Weed. 



During the spiing of 1888 I undertook an' extended series of ex- 

 periments with remedies for the plum curculio, and have reported the 

 results of the first season's work in the Bulletin and Report of the Ohio 

 Agricultural Experiment Station. The most successful method ihere re- 

 corded is that of spraying with I^ondon purple, the results indicating 

 that about three-fourths of the cherries liable to injury by the insect can 

 be saved by the treatment, and that as large a proportion of the plum 

 crop as is desirable may thus be brought to maturity. These experi- 

 ments were repeated this season, and I desire now to present some of 

 the more important results, and to indicate the conclusions to which 

 they point. 



Experiments with Cherries. 



The principal experiment with cherries this year was a duplicate of 

 the one carried on in 1888, the variety used being a half acre of Early 

 Richmond trees in full bearing. Last year the west half of this orchard 

 was sprayed and the east half left as a check. To eliminate any possi- 

 ble effect upon the results due to the difference in situation and expo- 

 sure, this year I reversed the treatment, spraying the east half and leav- 

 ing the west as a check. 



So far as possible this experiment was made an exact duplicate of 

 ihe one last season. During the time of spraying a great deal of rain 

 fell both \cais, necessualing three sprayings where two ordinarily would
