opportunity to experiment under Maine conditions with various 

 methods which have been recommended for the extermination 

 of wire worms in the past as well as to try out newer rnethods. 



It may be stated that the plot had been in potatoes last year 

 and in sod for a number of years previously. Last fall (1910), 

 the field was plowed late, after the ground was stiffened by 

 frost. 



The upper part of the field was divided into 20 plots, each 

 9 feet wide by about 200 feet long, the lower part into plots 6 

 feet wide by 100 feet long. 



On the 25th of July, the few stunted plants still remaining 

 on the upper part of the field were hoed down and the plots 

 without previous plowing were planted as follows, alternate 

 plots being left fallow. 



Grains coated with tar and Paris green. 

 Grains coated with arsenate of lead. 

 Check row, grains not treated. 

 Canada field peas. 



Plowed July 27 and weekly thereafter for 6 weeks. 

 Check row, grains not treated. 



Handful of tobacco dust placed in each hill ; grains 

 not otherwise treated. 



Plot 15. Handful of slaked lime placed in each hill; grains 

 not otherwise treated. 



Plot 17. Check row, grains not treated. 



Plot 19. Handful of "bug death" placed in each hill; grains 

 not otherwise treated. 



The remaining plots on the lower part of the field were 

 planted in the same way and in the same order, as a check, and 

 in -addition 3 shorter plots were added in which Sherwin-Wil- 

 liams Soil Fungicide was used in the hills. 



Germination tests upon the seeds show them to be of good 

 quality. 



Record of results. 



Plot I. Grains coated with gas tar, then rolled in Paris 



green until well covered. Grains failed to germinate as they 



were too heavily coated. Wire worms were still present in 

 September.
