are ready for setting in the orchard the 

 next year. This is a saving of an en- 

 tire year over present practices, from 

 the beginning of propagation till the 

 stock is ready for the orchard. 



Gassing the Peach Tree Borer 



The result of what is known as the 

 para-dichlorobenzene treatment for the 

 eradication of the peach-tree borer lead 

 experts of the United States Department 

 of Agriculture to believe that a practical 

 means has finally been found of ridding 

 orchards of this disastrously destruc- 

 tive pest. Previously the only effective 

 method of fighting the borer was by re- 

 moving the soil around the base of the 

 tree and digging the grubs out of their 

 galleries with a knife. It is estimated 

 that the borers have done $6,000,000 

 damage a year than that $2,000,000 a 

 year has been spent fighting them. 



The para-dichlorobenzene method 

 was first used extensively by orchard- 

 ists in 1919. It consists in sprinkling 

 fine crystals of the insecticide on the 

 soil around the base of the infected tree 

 and covering with earth to hold the gas. 

 The substance is highly volatile and 

 forms gas when the soil is between 74° 

 and 80° F. This gas is five times heavier 

 than air and sinks down through the 

 soil. It is highly effective against the 

 borer; and a pound of the insecticide, 

 costing not more than 25 cents, is suf- 

 ficient for 8 or 10 trees. The labor is 

 scarcely one-third of that formerly re- 

 quired. The saving therefore is great. 

 This year the para-dichlorobenzene 

 process has been used extensively in the 

 Georgia peach belt, some localities buy- 

 ing as high as 50,000 pounds and large 

 individual growers as high as 2 tons 

 each. Growers declare that it is one of 

 the greatest accomplishments in the his- 

 tory of the department, comparable to 

 the self-boiled lime-sulphur treatment 

 for control of brown rot and scab of the 

 peach.
