                           INTRODUCTION
     This guideline is one  of a  series  of test  guidelines that have been
developed by the Office of Prevention, Pesticides and Toxic Substances,
United States Environmental  Protection Agency for use  in the testing of
pesticides and toxic substances, and the  development of test data that must
be submitted to the Agency  for review under Federal regulations.

     The Office of Prevention, Pesticides and Toxic Substances (OPPTS)
has  developed this guideline through  a process of harmonization that
blended the testing  guidance  and requirements that  existed in the Office
of Pollution Prevention and  Toxics  (OPPT) and appeared in Title  40,
Chapter I,  Subchapter R of the Code of Federal Regulations  (CFR),  the
Office of Pesticide Programs (OPP) which appeared in publications of the
National Technical  Information Service (NTIS) and the guidelines pub-
lished by the Organization  for Economic Cooperation and Development
(OECD).

     The purpose of harmonizing these  guidelines  into a single set of
OPPTS guidelines is to minimize  variations among the testing procedures
that must be performed to meet the data  requirements of the U. S. Environ-
mental Protection Agency  under  the Toxic  Substances  Control Act  (15
U.S.C. 2601) and the Federal Insecticide, Fungicide and Rodenticide Act
(7U.S.C. I36,etseq.).

     Final  Guideline Release: This guideline  is available from the U.S.
Government Printing Office, Washington, DC 20402 on The Federal Bul-
letin   Board.   By  modem  dial   202-512-1387,  telnet   and   ftp:

     (a) Scope—(1) Applicability. This guideline is intended to meet test-
ing requirements  of the Federal Insecticide, Fungicide, and Rodenticide
Act (FIFRA) (7 U.S.C. 136, et seq.}.

     (2) Background. The source material used in developing this har-
monized OPPTS test guideline is OPP guideline 153A-4.

     (b) Identification and characterization of microbial pest control
agents. In  addition to the  information detailed under  OPPTS 860.1100,
the microbial pest control agent (MPCA) must be identified and character-
ized. If the  MPCA is a genetically  altered microbe,  then the nature  and
source (if applicable) of the inserted or deleted genetic material must be
provided.  The number  of viable,  infectious,  or  replicative entities
(propagules) per unit weight or volume of product must be specified as
well as the density of the product if it is a liquid.
