CURRANT. 



[1899 



During the past season little communication regarding presence of 

 our common corn crop attaclcs was sent, excepting some very local 

 observations on Corn Sawfly and Wheat-bulb Maggot. Injury from 

 Corn Sawfly is caused by the maggot feeding within the stem, and 

 finally gnawing it nearly through in a ring from the inside about 

 ground-level, the straw consequently falling. The maggot changes to 

 fly in the remaining part of the stem, and therefore "skimming" and 

 and collecting the stubble and burning it before the fiy comes out in 

 the following early summer is a sure remedy. Wheat-bulb Maggot 

 does not call for further notice; and " Wireworm " is noticed under 

 " Hops," as some good remedial treatment was suggested regarding 

 its attack to this crop. A note on carnivorous Wireworms is also 

 given.
