1933] SERVICE AND REGULATORY ANNOUNCEMENTS 181 
ing the grower himself or one of his competent employees responsible. Records 
are to be kept of the temperature of the water at 15-minute Intervals during 
the entire period of treatment, and when the inspector is absent such records 
are to be kept by the grower or employee in charge. Excepl where a grower 
has been definitely authorized by an inspector to proceed, treatment carried 
out in the inspector's absence is not considered as fulfilling the requirements 
for the issuance of Federal permits. 
In that paragraph of the discussion of hot-water treatment entitled "Process" 
in circular B.P.Q. — 337, it is stated that hot-water treatment is required either 
if eelworm infestation has been found "or if the inspector lias been unable to 
determine to his full satisfaction that the narcissus are free from eelworms." 
This latter clause refers to cases where the inspector is authorized in the 
Instructions to assume infestation, as in the case of weedy fields, or instances 
where the grower or his employees are themselves roguing the fields for eelworm 
infestations in advance of the inspector, and other similarly authorized cases. 
CHANGE IN PRESOAKING REQUIREMENT 
In the case of bulbs which have dried for more than 3 weeks, circular 
B.P.Q. — 337 stated that " they should be soaked for 12 hours in cold water 
before being treated." The advisory expression " should *' was used in place of 
making this a specific requirement, as experimental tests of the effect of such 
presoaking on many varieties had not been completed. Presoaking for a 2-hour 
period has been used commercially, however, for several years in certain sec- 
tions. The former recommendation is now modified to provide that such pre- 
soaking for 2 hours is a definite requirement in the case of bulbs which are to 
be treated after having dried for more than approximately 3 weeks. 
FIELD SANITATION 
In addition to the recommendations of circular B.P.Q. — 337, it is advan- 
tageous to dig all the healthy varieties and blocks first, and to store them in 
a separate section of the shed. This aids in preventing the spread of eelworms 
on tools and containers. Trays of infested varieties should never be placed on 
the same rack above uninfested lots. 
Except as modified or interpreted in this circular, the provisions of circulars 
B.P.Q. — 337 and B.P.Q. — 338 are considered as binding on inspectors as condi- 
tions of certification for the interstate movement of narcissus bulbs under 
Federal plant quarantine no. G2.
