during warm weather. The summer sul- 

 phur applications might also be supposed 

 to have some effect upon the young of 

 scale insects. The insoluble sulphides 

 of iron and copper proved rather neutral 

 as compared with sulphur ground in 

 sand. We then did not expect to obtain 

 a control of aphids by the use of these 

 compounds, but were somewhat unpre- 

 pared to note a marked increase in the 

 woolly aphis where iron sulphide and 

 copper sulphide was used. 



The woolly aphis was decidedly more 

 abundant on the sprayed than on the 

 check trees, and may be explained in 

 two ways. First, the increased vigor of 

 the sprayed trees produced a more sappy 

 condition, giving optimum nutrition con- 

 ditions for the aphis. Irrigation often

produces the same effect, and, further, 

 those trees sprayed with lime-sulphur 

 solution did not develop more, but rather 

 less aphis infection than the checks. 

 Here the trees had been retarded rather 

 than stimulated by the applications, but 

 the physiological sulphur effects were 

 markedly in evidence. Second, the fungi- 

 cidal action of the iron sulphide spray 

 may reduce the fungus diseases of the 

 aphids, and so aid them. This explana- 

 tion is sometimes offered to account for 

 the same results obtained with the bor- 

 deaux mixture. 



With regard to scale insects we did 

 not get very positive data. There was 

 only a trace of the San Jose scale on the 

 sprayed trees or the immediate checks. 

 With the greedy scale (Aspidiotus rapax) 

 we appeared to obtain 50 per cent control 

 by the use of iron sulphide. This result 

 appears in the tabulated fruit counts. 

 The green aphis did not increase mate- 

 rially upon those trees that were most 

 badly attacked by the woolly aphis. 



The increase of the woolly aphis by the 

 use of iron sulphide may prove to be a 

 somewhat serious complication requiring 

 special treatment to reduce the insects 

 where mildew control operations are car- 

 ried on. 



In making the counts, as shown in 

 the table herewith, the apples from each 

 tree were placed in boxes under it and 

 then an average box made up from 

 these by taking fruit at random from 

 all the boxes. In taking the fruit from 

 the boxes care was taken not to look 

 at the apples, and so avoid conscious 

 selection. When averages were taken 

 from the general spraying or main body 

 of the orchard they were made up from 

 50 to 100 boxes. The apples in the aver- 

 age box were then sorted, graded and 

 otherwise selected to show conditions 

 and percentages as desired. We have 

 made a careful study of this method of 

 obtaining average results and find that 

 it is both rapid and accurate. The accu- 

 racy is, of course, determined by the 

 number of average boxes taken. 



The fruit from lime-sulphur sprayed 

 Newtown trees was inadvertently picked 

 and removed before it could be counted. 

 The fruit from the pear trees was not 

 counted, but was examined and found to 

 be free from scab. 



These fruit counts show that the trees 

 of the White Winter Pearmain variety 



that were sprayed with iron sulphide 

 produced the largest fruit, taking into 

 consideration the yield per tree. The 

 tree that produced 38 boxes was much 

 overloaded, and so yielded very small 

 fruit. The trees in plot (h) yielded fruit 

 of remarkably fine size and quality, and 

 surpassed anything in any of the other 

 plots. The apples from the iron sulphide 

 plots were distinctly superior to those 

 from the checks. Check plot (k) was 

 sprayed in March with lime-sulphur solu- 

 tion (see first mildew application) and 

 showed no scabby fruit, and while the 

 scab was light even on unsprayed trees 

 (see check (m) ) it would indicate that 

 the soluble sulphides applied just before 

 the blossoms open may have a marked 

 influence upon this disease. The com- 



Do you 

 know 



That it takes a great deal of science 

 and skill to produce the kind of 

 trees that will make the best growth 

 and give the best satisfaction? 



Many people imagine that with a 

 good location one has only to plant 

 the tree in the spring and dig it up 

 in the fall. This may do for some, 

 but not with us. 



We took particular pains to secure 

 the best location here in the Yakima 

 Valley, where the soil is exceedingly 

 rich and well drained, and where the 

 growing season is long. 



By our constant cultivation during 

 the growing season, and otherwise 

 assisting Nature whenever possible, 

 we turn out a fine, stocky tree with 

 a splendid lot of healthy, fibrous 

 roots, unsurpassed anywhere. 



A good root system is the founda- 

 tion of a tree, and without this good 

 root system you cannot secure the 

 best results. 



If you intend to plant now or next 

 season, write for our catalog. It will 

 save you money.
