SWEET CORN 



quickly, and it is seen that the water supply 

 has been cut off and the plant soon dries 

 out. The leaves are the part first noticed 

 to be affected; at first one and then the 

 other dies until all are dead and fall off^. 

 Where the plant is very small all the leaves 

 may wilt at the same time and the plant 

 dry up, being soon lost. 



As far as known, no control methods 

 have beeh practical. There seem to be, 

 however, one or two measures which have 

 been employed which may be of value in 

 checking the disease. Pure seed from corn 

 which was not affected should be used. 

 This is highly important. Another method 

 would be rotation of crops so that corn 

 would not be placed on the same area more 

 than once every three or four years. It 

 has also been noticed that in some cases 

 certain varieties are not so susceptible to 

 the disease, and it might be greatly to the 

 advantage of the grower to plant varieties 

 which are less subject. These seem to be 

 the only practical measures thus far dis- 

 covered.
