TABLE 8. Showing condition of budded Mazzard stocks treated and untreated as regards 



foliage and measurements. 



* By an accident this section received one late spraying with Bordeaux and hence it is rendered un- 

 fit for comparison . 



The disease did comparatively little damage upon these stocks, but 

 as shown by the table, the treated sections were superior to the un- 

 treated, and the Bordeaux slightly superior to the ammoniacal solution 

 when 6 treatments are compared.* The difference between 5 and 6 

 treatments was not very marked. 



A comparison of the two tables brings out the fact which is note- 

 worthy in this connection, that the u buds"t on Mahaleb stocks aver- 

 aged greater in diameter throughout than those on the Ma/zard. This 

 difference is constant when stocks receiving the same treatment are 

 compared in each row, with the exception of the untreated section of 

 Windsors when compared with that treated once by mistake. This 

 constant difference in diameter, at 3 inches above the base (" caliper"), 

 is of such importance as to merit further observations. The author re- 

 grets that the control rows were left so small, and feels warranted in 

 drawing only the general conclusion, which was strikingly demonstrated 

 that the fungicides were effective to a remarkable degree in preventing 

 the disease and that treated stocks made the best growth. 



*The superiority of Bordeaux is not fully sho\vn by the figures, as in every case 

 the effect of the ammoniacal solution was evidently injurious to the health of the foli- 

 age. 



tThe term "bud" is here used, as among nurserymen, to indicate a budded stock 

 after the top has been cut off and the iuserted bud itself allowed to grow.
