FOREWORD
This Indian Standard ( Second Revision ) was adopted by the Bureau of Indian Standards on
23 August 1989, after the draft finalized by the Pest Control Sectional Committee had been
approved by the Food and Agricultural Division Council.
Dimethyl amine SL salts of 2, 4-D, namely, 2, 4-dichlorophenoxy-acetic acid are extensively used
in the control of weeds in agriculture and horticulture.
Soluble liquids ( SL ) dimethyl amine salts of 2, 4-D are manufactured to contain 22’5 and 58 per-
cent ( m/m ) of 2,4-D.
This Standard was published in 1961 and first revised in 1984. It has been revised again to
update its requirements in the light of the experience gained.
The empirical and structural formulae and molecular mass of dimethyl amine SL salts of 2, 4-D
are as indicated below:
0-CH2-COOH

In the preparation of this standard due consideration has been given to the provisions of the
Insecticides Act, 1968 and the Rules framed thereunder. However, this standard is subject to the
restricticns imposed under these, wherever applicable.
For the purpose of deciding whether a particular requirement of this standard is complied with,
the fkal value, cbservcd or calculated, expressing the result of a test or analysis, shall be rounded
cff in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values ( revised )‘. The
number of signifkant places retained in the rounded off value should be the same as that of the
specified value in this standard.

Standard Mark
The use of the Standard Mark is governed by the provisions of the Bureau of Indian
Standards Act, 1986 and the Rules and Regulations made thereunder. The Standard Mark on
products covered by an Indian Standard conveys the assurance that they have been produced
to comply with the requirements of that standard under a well defined system of inspection,
testing and quality control which is devised and supervised by BIS and operated by the pro-
ducer. Standard marked products are also continuously checked by BIS for conformity to
that standard as a further safeguard. Details of conditions under which a licence for the use
of the Standard Mark may be granted to manufacturers or producers may be obtained from
the Bureau of Indian Standards.
