MILDEW ON THE VINE. 

 (Odium Tuckerii.) 



Mildew is a fungus, and imparts a whitish appearance 

 to the leaves, bunches, and stems of vines. ' It robs 

 the plant of its juice, and interferes with its respiration. 

 There seems to be every reason to believe that the 

 fungus is communicated to the plants from the soil. 

 Every specimen of these fungi emits annually myriads 

 of minute seeds, and these are wafted over the soil by 

 every wind, vegetating and reproducing seed if they 

 have happened to be deposited in a favourable place, 

 or remaining until the following spring without germinat- 

 ing. These fungi have the power of spreading, also, by 

 stooling or throwing out off-sets. They are never 

 absent from the soil, and at some period of their growth 

 are annually to be found upon the plants liable to 



their inroads. They are more observed in cold, damp,
