(1) 



U) 



PHYSICAL STATE OF THE TEST COMPOUND 



INDICATION OF DIRECT, MASS APPLICATION VS. REMOTE. 

 PARTICULATE APPLICATION (I. E. , DISPERSION VS. 



APPLICATION OF THE UNDISPERSED COMPOUND) 



(3) INDICATION THAT INFORMATION ON CORRELATION OF 

 ACTIVITY AND CHEMICAL STRUCTURES OCCURS IN 

 THE DATA SOURCE 



Note: With only one or two exceptions, coding in Field A is restricted to a description of the 

 state and method AT THE TIME OF APPLICATION to the host or the test organism. See the Key for 

 specific directions and explanation of exceptions. 



1 Gas; vapor (a compound applied in a normal 



environment such as air, water, or soil; 

 either undiluted or a per cent composition 

 of a mixture with air, components of air, 

 or other innocuous gas) 

 A Adsorbed gas 



2 Liquid (undiluted compound, not dispersed) 

 B Liquid (undiluted compound) applied as a 



spray 

 K Liquid (undiluted compound) applied as a 



mist or aerosol 



3 Solid (undiluted compound, not dispersed) 

 C Solid (undiluted compound) applied as a 



dust 



4 Solution (not dispersed) 



D Solution applied as a spray 



M Solution applied as a mist or aerosol 



5 Emulsion (not dispersed) 



E Emulsion applied as a spray 



N Emulsion applied as a mist or aerosol 



6 Suspension (not dispersed) 



F Suspension applied as a spray 



Suspension applied as a mist or aerosol 



7 Suspension in a solid (not dispersed) 



(salve or powder) 

 G Suspension in a solid, applied as a dust 



(dust = dispersed powder) 



(The solvent, if specified, should be expressed 

 in Field C. ) 



(The vehicle, if specified, should be expressed 

 in Field C. ) 



(The conditioning agent, if specified, should be 

 expressed in Field B; the vehicle, if specified, 

 would be in Field C. ) 



The article contains information on the 

 correlation of activity and structure of 

 chemical compounds. 



"Dispersion" is used here to mean scattering the test material by use of a sprayer, 

 dispersion' 



atomizer, duster, 



aerosol; "dispersion" is NOT used in Field A definitions of the Code to describe mechanical spreading 

 or smearing of the test material over the surface of- -or diffusing through the substance of- -a test 

 organism or host. An examination of the Code terms will clarify this.
