INSECTICIDE AND FUNGICIDE BOARD. 597 



either ceased practicing this form of adulteration or so changed their 

 labeling as to correctly describe the article containing the mineral 

 oil. During the campaign 19 seizures were made and prosecution 

 of the manufacturers recommended in 29 cases. Since this practice 

 has not been entirely broken up, but is still being continued by a 

 comparatively few manufacturers or jobbers, the campaign of seizure 

 and prosecution will be continued. 



The campaign against adulterated and misbranded disinfectants 

 of various kinds has been continued during the year, with especial 

 reference to pine-oil disinfectants sold for general disinfecting pur- 

 poses ; paradichlorobenzene powders and blocks sold as disinfectants, 

 and new or hitherto uninspected disinfectants the labels of which 

 have flagrantly false and misleading statements. Investigations by 

 the board showed that pine-oil disinfectants were not suited for gen- 

 eral disinfecting and that the paradichlorobenzene blocks and pow- 

 ders were not disinfectants. As a result of the campaign, the labels 

 of many of the pine-oil and other disinfectants have been corrected, 

 fi number of manufacturers have ceased selling pine-oil disinfectants 

 for general disinfecting purposes, and most of the manufacturers of 

 paradichlorobenzene powders and blocks have removed all disinfect- 

 ant claims from their labels and literature. Since the practices 

 spoken of above have not been entirely broken up, and since new 

 disinfectants are constantly coming on the market, the labels and 

 literature of which commonly bear false and misleading claims, the 

 campaign to control disinfectants will be continued from year to 

 year. 



The campaign started during the fiscal year 1919 against insect 

 powder adulterated with daisy flowers and insect flower stems and, 

 extending through the fiscal years 1920 and 1921, was further con- 

 tinued during the fiscal year 1922. Several seizures of goods adulter- 

 ated with daisy flowers were made and prosecution recommended of 

 a number of different manufacturers. Some important cases involv- 

 ing this form of adulteration are now pending in the courts and will 

 be vigorously prosecuted. While this form of adulteration has been 

 reduced steadily during the period of this campaign, it does not 

 appear to have been entirely abandoned. Therefore the campaign 

 will be continued. 



The campaign against naphthalene nest eggs, recommended to 

 control poultry lice and mites and act as disinfectants, which was 

 begun during the fiscal year 1920. was continued during the fiscal 

 years 1921 and 1922, with the result that all insecticidal and disin- 

 fectant claims were removed from the labels and literature of most 

 of the naphthalene nest eggs sold on the American market. 



INTERSTATE SAMPLES. 



During the fiscal year the board reported to the Solicitor of the 

 department S9 cases presenting alleged violations of law, with recom- 

 mendation that the facts be transmitted to the Attorne}^ General to 

 institute criminal action or seizure proceedings. Disposition was 

 made of 153 cases by correspondence with the manufacturers. These 

 cases presented violations which were technical only, not flagrant, 

 or cases in Avhich the manufacturer gave reasonable and adequate 

 explanation of his failure to conform to the provisions of the act.
