Stem Rot Resistant Asters 
I T IS most encouraging and convincing to see resistant strains stand up nearly 100% 
in thoroughly sick soil, as shown above, alongside ordinary commercial stock that 
goes down nearly 100%. 
We have received a few unfavorable reports on our resistant strains of asters, surprisingly 
few considering the number of favorable ones. In several cases we investigated, the 
plants were affected with the "yellows” and one was in a cloth house; this emphasized 
the necessity of maintaining these houses tight, 100% so, to keep out the leaf hopper 
that alone is responsible for the fatal yellows. There are a number of forms or varieties 
of rot that affect asters, one a blackening of much of the stem. This is not nearly so 
fatal or wide spread as the common stem rot that works through the stem near the base. 
Our Resistant strains are bred to overcome or resist this and they will do so to the 
extent of 85% — 90%, even in soil that has grown asters for several years, as the above 
photo proves. Asters have been grown for four consecutive seasons in this house
