and corn. It would therefore appear that arsenical poisons might 

 protitabh^ be used in bollworm control on tomatoes, either alone or in 

 fungicidal preparations designed to prevent fungous diseases. Appli- 

 cations of poisons should be made as soon as bollworm moths are 

 observed in numbers in tomato fields. Two or three applications at 

 intervals of a week or ten days should suffice to protect from important 

 injury. 



Early sweet corn may be planted in belts through the tomato field 

 in a way that will afi'ord much protection to the earliest fruit. A sys- 

 tematic effort toward the destruction of all larvae found in these trap 

 belts would contribute much toward lessening future injury. 



Bollworm injury to tobacco is confined principally to the ''bud." 

 A treatment which has been in practice for many years by the tobacco 

 growers of Florida, and possibly elsewhere, is to sprinkle into the 

 "bud" at frequent intervals, by means of a tin can with perforated 

 bottom, a mixture of Paris green and cornmeal. Where tobacco is 

 sprayed with arsenites in the control of the " horn worm," this treat- 

 ment will probably keep the bollworm in subjection.
