30 THE REPORT OF THE No. 19 



some orchards treated with the uncooked wash. On the other hand, it should 

 be stated that both washes gave good results in many orchards. The reason 

 for this variation in results is difficult to find; for example, Mr. W. H. Bunt- 

 ing of St. Catharines, who did not check the development of the scale with 

 the cooked wash, is a most careful and thorough sprayer. On examination of 

 Mr. Bunting's plum, peach, pear, and apple orchard in late October, Mr. P. 

 W. Hodgetts and myself found the scale more abundant and more wide spread 

 than at the close of any previous season. Like results were observed in Mr. 

 Bunting's orchard at his home in St. Catharines. The scale had spread and 

 parti V encrusted many trees in spite of treatment with the cooked wash in 

 the spring. 



Mr. Titterington's orchard composed of peach and plum chiefly, just 

 across the Welland Canal, was sprayed also in the spring with the cooked 

 lime-sulphur wash. The trees near the road at the south end were fairly 

 free from scale, but many trees at the north end were quite badly infested. 



Mr. Irvine, near Queenston, on the Queenston Road, used the cooked 

 lime-sulphur wash prepared according to the usual formula. The results 

 might be said to be good in spite of the fact that there is now a 

 ^sprinkling of scale in his peach orchard. Many of his Japan plums and 

 a few of his peach trees, however, are badly infested. Mr. Muir, of Virgil, 

 also sprayed with the cooked wash and speaks very highly of its merits. Cer- 

 tainly the condition of his trees at the end of October would seem to justify 

 his opinion, for there was but a slight scattering of scale. This is saying a 

 good deal when we remember that the scale is very bad throughout the Virgil 

 district. In Mr. Muir's orchard the wash on the bark was quite visible in 

 most of the trees up to the end of the season. 



Mr. Lambert's orchard near the Welland Canal was sprayed thoroughly 

 in early spring with the cooked lime-sulphur-salt wash. Two rows of Japan 

 plums, badly encrusted last season, were in good condition, and the scale 

 was not abundant. These trees showed very plainly the wash at the end of 

 the season, and were perhaps the best in this regard of all the trees we ex- 

 amined. To my mind the presence of the salt made the wash more adhesive 

 than that applied by his neighbors; moreover, it is very likely due to the 

 extra adhesiveness of this wash that the scale was so reduced in numbers. 



In the peach orchards of Mr. Porter Adams, on the Queenston road, near 

 Queenston, the uncooked lime-sulphur wash Was used. The results were good, 

 although there was a slight sprinkling of scale throughout his orchard. Un- 

 treated trees were very bad, the bark being wholly encrusted. An interesting 

 observation in this orchard is worth recording. There were three, and only 

 three so far as we could find, badly injured peach trees in the sprayed orch- 

 ard, and these were not close to one another. These received the same appli- 

 cation as the other trees, but they are now encrusted with scale. 



Mr. Bradley, near Mr. Adams, was not so successful with the uncooked 

 wash. We are told, however, that the trees received a one-sided application 

 on account of the high winds that prevailed at the time of spraying. The 

 older trees of this orchard are now badly infested. 



Mr. C. A. Secord used the uncooked lime-sulphur wash in his fine 16-acre 

 peach orchard, and secured excellent results. Scale was there, but it was 

 rather hard to find. The owner is perfectly satisfied with the results, and 

 will use a similar wash next spring. 



Mr. Beattie, Scale Inspector, of St. Catharines, tried Scalecide, Carl- 

 son's Mixture, and the uncooked lime-sulphur wash in his own orchard.
