Resumo: | The objective of this work was to evaluate the efficiency of a new method, developed for predicting density and floristic composition of weed communities in field crops. Based on the use of solaria (100 mm transparent plastic tarps lying on the soil) to stimulate weed seedlings emergence, the method was tested in Tandil, Argentina, from 1998 to 2001. The system involved corn and sunflower in commercial no-till system. Major weeds in the experiments included Digitaria sanguinalis, Setaria verticillata and S. viridis, which accounted for 98% of the weed community in the three years of experiments since 1998. Large numbers of Tagetes minuta, Chenopodium album and Ammi majus were present in 2001. Comparison of weed communities under solaria with communities in field crops indicated that the method is useful for predicting the presence and density of some major weed species, at both high and low densities, of individuals in areas of 10 ha using only five solaria. Low density of weed species makes the method particularly useful to help deciding the time for herbicide applications to avoid soil contamination. |

O método é baseado no uso de solaria (plástico transparente de 100 mm sobre o solo), a fim de estimular o aparecimento de ervas daninhas, e foi testado em Tandil, Argentina, de 1998 a 2001. O sistema envolve milho e girassol, em cultivos comerciais em semeadura direta. As principais espécies experimentadas foram Digitaria sanguinalis, Setaria verticillata e S. viridis, que responderam por 98% da comunidade nos três anos de experiência. Números altos de Tagetes minuta, Chenopodium album e Ammi majus estavam presentes em 2001. A comparação de comunidades de ervas daninhas sob solaria com comunidades fora de solaria indicou que o método é útil para predizer a presença e a densidade de espécies com densidades altas e baixas de indivíduos em áreas de 10 ha com o uso apenas de cinco solaria. Espécies com baixas densidades tornam o método particularmente útil para ajudar a decidir o uso ou não de herbicidas para evitar a contaminação da terra.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCalviño, Pablo AntonioEyherabide, Juan José2006-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7153Pesquisa Agropecuaria Brasileira; v.41, n.3, mar. 2006; 409-413Pesquisa Agropecuária Brasileira; v.41, n.3, mar. 2006; 409-4131678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/7153/4198info:eu-repo/semantics/openAccess2014-06-10T18:55:01Zoai:ojs.seer.sct.embrapa.br:article/7153Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-06-10T18:55:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
