The effect of the scab on the size of a]>ples is shown from the fact that 

 a bushel of Xewtown Pippins \vhi(;li were free from scab contained L*Oli 

 apples, while 317 scabby api)les were put into the same measure. The 

 average weight per ap[)le was 4 and L*.5 ounces, respectively.

The brief accounts of similar ex[)i'rrm('iil.s in L;iwrciice County, Ohio, 

 iu coopi'iation with tlic station. c(»rr()b(»iate tliose of the cxi)eriments 

 al)0ve described. Similar e.\i>'eriments to i»revent p<'ar scab are brietiy 

 reported, in which the dilute Bordeaux mixture and modified eau celeste 

 were about ecjually beneficial, but the latter injured the foliage to some 

 extent. 



Spriiji'infi for the plum cnrotVu) (i)p. 213-21G). — Reports from a number 

 of fruit growers in Ohio are given, in.dicating- that spraying with Paris 

 green is considered an effective remedy for the plum curculio. The 

 need of caution in the preparation of the mixture in oider to prevent 

 injury to the foliage, is urged. It is thought that 1* ounces of Paris 

 green to 50 gallons of water is sufficient, if three or four applications 

 are made during the season, and that the use of the dilute Bordeaux 

 mixture in connection witli the insecticide will prevent injury to the 

 foliage. This mixture of fungicide and insecticide was also used with 

 beneficial effects on ])ear trees affected by the curculio. 



Sprayhifi for ^' .shof-/iol(''\fini(/i(s of flic plum (pp. 21G, 217). — Septoria 

 crra-sina was prevalent in plum orcliards in 1<S9I, causing the prema- 

 ture dropping of the leaves. Paris green alone aggravated the trouble, 

 but in connection with the dilute Bordeaux mixture it was quite 

 effective in preventing the disease. The author advises the use of the 

 combination two or three times during the season, after which Paris 

 green should be applied alone once or tAvice.
