and corn. It would therefore appear that arsenical poisons might 
profitabl}" 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 afiord much protection to the earliest fruit. A sj^s- 
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 principall}^ to the ^'bud.'' 
A treatment which has been in practice for many years by the tobacco 
growers of Florida, and possibh^ elsewhere, is to sprinkle into the 
"bud" at frequent intervals, b}^ means of a tin can with perforated 
bottom, a mixture of Paris green and cornmeal. Where tobacco is 
spraj^ed with arsenites in the control of the "horn worm," this treat- 
ment will probabl}^ keep the bollworm in subjection.
