Authors should type in the "Comments to the Editor" a cover
letter presenting the work and explaining the main contribution to the
Weed Science. The letter should indicate that the work was not submitted
for publication elsewhere.
Articles and reviews should not exceed 25 pages (A4 paper with margins
of 3 cm, font Times New Roman size 12, pages and lines numbered sequentially),
including tables and figures. The Research Notes should not exceed 12
pages, including tables and figures.
The text should be typed into the Word (Microsoft) program and 1.5 spacing.
The main divisions of the text (Introduction, Methods, and Results and
Discussion) should be in uppercase and bold, and centered on the page.
Scientific notes do not have divisions.
The title of the manuscript must reflect the content of the work and should
not have subtitles, abbreviations, formulas and symbols. The scientific
name must be indicated in the title only if the species is unknown.
The names of the author and co-authors should be included in the Submission
System in the same order they appear in the final work. Please, do not
indicate the authorship of the work in the text of the manuscript.
The abstract must have the goal of the research clearly and concisely,
the methods briefly and the most relevant results and conclusions. The
text should not exceed 250 words with short sentences with complete connection
with each other. It must not contain references. The title and abstract
in Portuguese should be faithful versions of the text in English.
The key words in English and Portuguese should not repeat title words
and should include the scientific name of species. Words must be separated
by a comma and begin with small letters, including the first term. The
authors should present from 3 to 6 terms, considering that a term may
be composed of two or more words.
The Introduction should have one to two pages, include the rationale for
conducting the work, placing the importance of the scientific problem.
The information contained in the Introduction should be sufficient to
establish the hypothesis of the research. The authors should cite recent
studies published in scientific journals, but the citation of classical
works is accepted. The authors should avoid the citation of summaries
and abstracts. In the last paragraph of the Introduction, the authors
must submit a scientific hypothesis and the objective of the study, the
same as the summary.
Material and Methods should present a description of the experimental
conditions and methods used so that there is enough information to repeat
the work. Formulas, expressions, or mathematical equations should be initiated
to the left of the page. Include references to statistical analysis and
report about the transformation of the data. Indication of statistical
significance should be as follows: p <0.01 or p> 0.05 ("p"
in lower case).
In Results and Discussion, the authors should present the research results
and discuss them in order to relate the variables examined to the objectives
of the study. The mere comparison of results with the data presented by
other authors did not characterize the discussion of them. The authors
should avoid excessive speculation and the data should not be presented
both in tables and figures.
There will be no extra chapter for Conclusions, but the authors may finish
the chapter "Results and Discussion" with a summarized conclusion.
Only the strictly necessary references for the understanding of the article
should be cited, we recommend around 25 references to articles and scientific
notes. The list of references should begin on a new page.
The author citations in the text should be in small caps, followed by
year of publication. For two authors, use "and". Having more
than two authors, cite the last name first, followed by et al. More than
one article of the same authors, in the same year, must be indicated with
small letters: Silva et al. (2008a, b). Personal communications, or unpublished
reports should be cited in footnotes. They should not appear in References.
The citation of papers published in scientific events should be avoided.
References are normalized according to the models bellow and should be
in alphabetical order and chronological order of the year; having two
or more authors, separate them by semicolons; the titles of journals should
be spelled out and include only the works cited in the text, tables and
/ or figures, as follows:

por Brachiaria decumbens e seus efeitos em plantas de eucalipto. Planta
Daninha, v.26, n.2, p.369-374, 2008
b)Books and book chapters
Should be avoided.
SENSEMAN, S. A. Herbicide handbook. 9. ed. Lawrence: Weed Science Society
of America, 2007. 458 p.
c)Dissertations and Theses
Should be avoided. Look forward referring only the articles published
in whole, in indexed publications. Only very recent thesis, whose articles
have not yet been published, should be cited.

glyphosate em biótipos da planta daninha Lolium multiflorum (Lam.).

Superior de Agricultura "Luiz de Queiroz", Universidade de São
Paulo, Piracicaba, 2008.
When absolutely necessary to the understanding of the work, tables and
figures should be shown in the text. The table or figure and its respective
caption should be self-explanatory. The titles of tables and figures should
be clear and complete and include the name (common or scientific) of the
species and the dependent variables. Figures should appear at the end
of the text. We considered figures: graphs, drawings, maps and photographs
used to illustrate the text. Authors should avoid colors in the figures,
except for photographs. For composite figures, each graph should be marked
with the inscription "(a, b, c...)" in lowercase.
Tables and figures should be placed after the listing of references. The
numbers in the tables should be aligned with the comma in the column.
Figures and tables must be accompanied by its caption, with the units
following the International System of Units and positioned at the top
of the columns in the tables. The magnitudes, in case of compound units,
should be separated by space and an indication of the denominators must
be rated in superscript. Examples: (µmol m-2 s-1), [mg (g MS)-1].
- Not to mention the lab, department, center or university where the research
- In the online submission of work, the names of the author and co-authors
must be entered into the System in the same order they appear in the final
work. Do not indicate the authorship of the work in the text of the manuscript.
- Failure to standards will require the return of work.
