14 Variety Trials 



spring of 1920 we succeeded in putting the vineyard in pretty 

 good condition and there has been little loss since. The following 

 is a list of the varieties set. Those marked with $ failed to live, 

 the number immediately after the $ show the number that 

 died, again the number following show how many were reset. 

 Those marked with * were reset in 1919, while those marked f 

 were set for the first time in 1919. This list does not include 

 the V. vinifera varieties as they appear elsewhere. This vine-- 

 yard was .planted in cooperation with the U. S. Dept. of Agri- 

 culture, it furnishing all vines bearing a number; the number 

 being their nursery number. 



All grapes are more or less subject to brown rot. and bird's 

 eye rot in this climate. As a preventative these grapes were 

 sprayed three times in 1922, 4-4-50 Bordeaux mixtitre being used. 

 Heavy and continuous rains prevented this giving the 

 degree of protection that could reasonably have been expected 

 but as all were treated alike the degree of susceptibility observed 

 /should be accurate. Those varieties only slighly subject to rot 

 are marked 1. Those showing considerable disease are marked 

 2, while those in which the disease was so severe as to seriously 

 damage the market quality of most of the bunches are marked 3. 



These numbers appear at the extreme right in the complete list. 



Phylloxera has not been present thus far in great enough degree 

 to make if possible to give an accurate study of variety suscepti- 

 bility -to this disease. 



Leaf roller has given more or less trouble every season since 

 the vineyard was planted. A few varieties seem wholly resistant 

 to this insect while none seem conspicuously susceptible above 

 the general average. Those that are resistant are marked* on 

 the list of fifty.
