4 CONTROL SERIES No. 92 



Boldface type indicates low purity, low germination, excessive weed seed, 

 noxious weeds not declared, or excessive inert material, depending upon the 

 column in which it is found. 



Other deficiencies are enumerated as follows: 



(1) Noxious weeds found. 



(2) Old seed (as shown by given date or by correspondence with the whole- 

 saler). 



(3) Ingredient found, but not declared. 



(4) Ingredient declared, but not found. 



(5) Ingredient declared, but percentage found after adding proper tolerance 

 is less than 5%. 



(6) Term not specific. 



The letter "R" after the germination percentage in the table of vegetable 

 seeds indicates that the sample has received one or more retests. 



All lots of seed included in this report were tested according to the Rules for 

 Seed Testing adopted by the Association of Official Seed Analysts. 



"Tolerance" is applied to both purity and germination, except in those tables 

 which list seeds falling under sections of the law not requiring purity or germina- 

 tion on the label. For the application of "Purity Tolerance", the sample is 

 considered as made up of two component parts: (1) the component being con- 

 sidered, and (2) the balance of the sample. The tolerance in percentage allowed 

 for each component shall be two-tenths of one per cent (0.2%) plus twenty per 

 cent (20%) of the lesser of the two parts. "Germination Tolerance" has been 

 applied between a given germination and the result of the germination test as 

 follows: 



Given Germination Allowable Variation (%) 



90 or over 6 



80 or over, but less than 90 7 



70 or over, but less than 80 8 



60 or over, but less than 70 9 



Less than 60 10
