replaced, tamped with air compressor. 

 Chemical applied around all pipes and 

 ducts. All exposed soil or pad treated, 

 1 gal. per 10 sq. ft. Slab areas covered 

 with gravel after treatment, then poly- 

 ethylene vapor barrier, next steel rein- 

 forcement, finally concrete poured. After 

 houses constructed, soil adjacent to out- 

 side foundation treated in 6-in.-wide, 12- 

 in.-deep trench, 4 gal. to 10 linear ft. No 

 responsibility for retreats. Insurance, 

 thorough preparation, and supervisor on 

 job at all times essential.)

 ment tests have been continued and all 

 chemicals mentioned in 1958 report re- 

 main effective.)

 surface soil sprayed 1 gal. per 10 sq. ft. 

 Debris removed.) 



1960c, p. 25. (U.S., in Memphis, Tenn., pre- 

 treatment with soil poisons costs 40% of 

 cost control in slab houses, 5% less than 

 correction in crawl space houses; in Okla- 

 homa City 25% less.)

 ston (Forest Service) warns to discon- 

 tinue downward trend in reducing con- 

 centrations of soil poisons for economic 

 reasons. Many pest control operators feel 

 Federal Housing Administration's concen- 

 trations for soil poisons are too low. In the 

 Canal Zone, Panama, twice as much in- 

 secticide required for same results as in 

 Mississippi; high rainfall may have bear- 

 ing. Ethylene dibromide an effective soil 

 fumigant in California for 4 years; Bill 

 Butz (Purdue) stated when a residual 

 chlorinated hydrocarbon is used with a 

 fumigant, the residual will not reach as 

 far as the fumigant will to get the initial 

 toxicity. Joe Kahn (Purdue) stated re- 

 search shows that ethylene dibromide will 

 not move through the soils of midwest- 

 ern United States because of the texture 

 and compactness of these soils.)

 the soil was thoroughly treated especially
