130 PEACH LEAF CURL". ITS NATURE AND TREATMENT. 



October 1, 1894. — The results of this experiment are rather disappointing, as I was 

 led to believe when I made the estimate of the loss of foliage in Jmie that the results 

 would be more satisfactory than with experiment 3. Whether the solutions used 

 had the effect of neutralizing each other, or whether formula B, having been first 

 applied, prevented any benefit from formula C, I can not tell. 



Exper'mient 5: 



June 23, 189-4. — The first spraying of this lot was followed by ten hours' rain, the last 

 spraying by good weather. The treated trees present a fine appearance, but the con- 

 trast is not so great as in some other experiments, for the control trees are an outside 

 row and apparently not as badly affected as those farther in the orchard. I do not 

 anticipate a very large difference in the fruit yield. 



October 1, 1894. — This experiment has turned out just as I thought it would. The 

 difference in the amount of fruit from the sprayed and misprayed trees is not great, 

 yet it is quite satisfactory considering the conditions. 



Experiment S.- 

 June 23, 1894. — This experiment was thoroughly made, but was imfortunately 

 followed by twenty-four hours of warm rain, commencing ten hours after the spray- 

 ing, sothat the result is not as satisfactory as desired, but the effect is so noticeable 

 that the difference can be seen half a mile away. 



October 1, 1894. — The results of this experiment are entirely satisfactory. In spite 

 of the fact that the spraying was followed by rain and then by very cold weather, 

 the yield of fruit was one-third more on the treated trees than on the untreated trees, 

 but what pleases me most is the very great difference in appearance of the trees now. 

 Those that were treated have made double the groM'th this season that the untreated 

 rrees have. They are holding their leaves late and have twice the buds set for another 

 year, and are fresher and healthier in every way. 



Experiment 7: 



June 23, 1894. — The result of this experiment thus far seems to show that the 

 formula used is not strong enough to accomplish the work desired. There is at this 

 date les i difference to be noted between the treated and untreated trees than in any 

 other experiment. 



October 1, 1894. — This exi>eriment has resulted about as I thought it would, from 

 the appearance of the trees in June. I do not think formula B is strong enougli. 



Experiment 8: 



June 23, 1894. — I regard this as one of the most valuable experiments in the series. 

 It has so far shown the best results. The imtreated trees look as though a blight had 

 struck them, appearing at this date as if they were going to die, while the sprayed 

 trees look as fresh and healthy as young trees that never had any disease. One 

 curious thing I have noticed is in relation to a branch from one of the untreated trees 

 which reaches across to one of the treated ones. This branch, of course, got sprayed 

 w'hen the tree was sprayed with which it mingles, and it is as full of leaves and fruit 

 as the treated tree, while the balance of the tree to which it belongs is bare of leaves 

 and fruit. 



October 1, 1894. — The final results of this experiment have proved what I expected. 

 There is a greater difference in yield than in any other experiment, while the differ- 

 ence in appearance between the treated and untreated trees is yet very marked. The 

 treated trees look as fresh and healthy as young trees, while the others still look 

 very bad. These trees have always been very heavy bearers, and consequently have 

 not attained a very large size. They were never very badly affected by leaf curl till 

 this year.
