320 EXPERIMENT STATION RECORD. 



Observations relative to the life liistory of the tobacco worm are 

 given, in which it is shown that at the station there is evidence of 3 

 annual broods instead of 2, as hitherto believed. From the grower's 

 standpoint the broods appearing one early in July and the other early 

 in August are of the most consequence. 



A summarj^ by the author shows that it is not necessary to spray 

 tobacco more than 3 times, provided the times of api)lication are well 

 chosen. Based upon his experience, the proper times of applying 

 Paris green would be early in July, again early in August, with a third 

 application about the middle of August. One part of Paris green to 

 160 gals, of water is of sufficient strength if properly aDplied, and 

 under no circumstances is a strength greater than 1 part to 120 gals, 

 advised. 



Some good form of knapsack sprayer with an agitator is recommended 

 for use where tobacco is grown on a sufficient scale. To those dislik- 

 ing the use of Paris green, a solution of cobalt placed in flowers ot 

 jimson weed is recommended. 



Grasshoppers have been found to cause considerable damage to 

 tobacco when other herbage becomes scarce in the latter part of sum- 

 mer, and it is recommended that all unnecessary growth which would 

 harbor these pests should be kept down around the tobacco fields.
