trade, provided orders are placed sufficiently early. Farmers 

 and dealers should order now, goods to be shipped as soon as 

 wheather conditions will permit. Official ekemption of in- 

 secticides from embargoes does not insure rapid transporta- 

 tion." This reads very much as though it might have been 

 dictated by a shipping agent who had been rather busy the 

 last few months. 



It is safe to assume that we agree as to the great desirab- 

 ility of making a dormant or delayed dormant application of 

 lime sulfur wash, sometimes with other materials added, and 

 the well known calyx or codling moth spray. These two treat- 

 ments are by far the most important the apple grower can 

 make and usually the latter is of greater value than the for- 

 mer, because the codling moth is not only a general but very 

 injurious pest. 



We further admit that dormant applications of lime sul- 

 fur wash at winter strength or some other equally effective 

 insecticide is the most satisfactory method ow controlling 

 J^an Jose scale. It is well known by some at least that this 

 pest infests Kieffer pear, sour cherries and quinces to such a 

 slight extent that spraying of these trees to control scale is 

 not as a rule necessary and may therefore, under present con- 

 ditions be omitted. Experience in the Hudson Valley has 

 shown it to be moderately safe to omit the dormant spray 

 for a year or two, at least in orchards where scale has not 

 been abundant the last two or three seasons, though this 

 should not be construed as guaranteeing immunity from in- 

 jury if there is no dormant spraying. It has worked out fairly 

 satisfactorily in a number of cases and the probabilities are 

 that equally good results would follow in many New Eng- 

 land orchards, since parasites are apparently very effective in 

 cheeking this pest in many localities. 



The delayed dormant spray, where conditions permit 

 and justify its employment, is more valuable than the earlier 

 dormant application, since if arsenate of lead or other poison 

 be added and the treatment be delayed until the young 

 leaves are about half an inch long or even until the pink
