1. Efficacy of Trichogrammatidae Species (Hymenoptera) Submitted to the Herbicide Glyphosate
RESUMO: Informações sobre herbicidas seletivos, incluindo o glyphosate, que não afetam organismos não alvo, como inimigos naturais, são importantes nos programas de manejo integrado de pragas na cultura do milho. O glyphosate, na dose de 13,94 L ha-1, foi avaliado em fêmeas de 10 espécies de Trichogrammatidae (Hymenoptera). Uma fêmea de cada espécie

2. To be or not to be a carcinogen; delving into the glyphosate classification controversy
The International Agency for Research on Cancer (IARC) placed the most widely used herbicide glyphosate (GLY) into the category 2A (probably carcinogenic to humans), a classification questioned by experts from academia and industry. This article critically appraised the epidemiological and experimental data that led the IARC working group (WG) to consider GL

3. Quick Test for Detecting Glyphosate-Resistant Ryegrass Seeds
RESUMO: A comercialização de sementes de azevém com a presença de biótipos resistentes promove a dispersão da resistência para áreas isentas do problema. Diante disso, o objetivo deste trabalho foi desenvolver teste rápido para diferenciação de sementes suscetíveis e resistentes ao herbicida glifosato, visando identificar lotes contaminados com s

4. Glyphosate-based herbicide affects biochemical parameters in Rhamdia quelen (Quoy & Gaimard, 1824 and) Leporinus obtusidens (Valenciennes, 1837)
Rhamdia quelen (jundiá) e Leporinus obtusidens (piava) foram expostos a formulação comercial Roundup(r), um herbicida a base de glifosato nas concentrações de 0,2 e 0,4 mg/L por 96h. Os efeitos do herbicida foram analisados na atividade da alanina aminotransferase (ALT), aspartato aminotransferase (AST) e glicose no plasma, glicose e proteína na camad

5. PARÂMETROS DE ESTRESSE OXIDATIVO E ESTUDO DE LESÕS HISTOPATOLÓGICAS EM JUNDIÁS (Rhamdia quelen) EXPOSTOS A AGROQUÍMICOS
Due to the proximity of crop and fish culture areas, some agrichemicals that could be harmful for fish could enter into fishponds by different ways, such as by leaching through rain. The contamination of the aquatic environment by pesticides is a problem of global importance because of its toxic effects on non-target organisms. These products may affect toxi

6. Nitrogen transformations in soil-plant system after herbicide application / Transformações do nitrogênio no sistema solo-planta após aplicação de herbicidas
Herbicide adoption might modify nitrogen dynamics in agroecossystems and, for consequence, nutrient availability for plants and microorganisms. These modifications may occur because of plant physiologic changes and/or due to herbicide effects on activity and composition of soil microbial community, which has important functions on system N modifications. In

7. Estudo Teórico de Mecanismos para a Etapa de Eliminação da Síntese do 5-Enolpiruvilchiquimato-3-Fosfato (EPSP) catalisada pela EPSP Sintase de Oryza sativa.
In the sixth step of the shikimate pathway, catalyzed by 5-enolpyruvylshikimate-3- phosphate synthase (EPSPS), phosphoenolpyruvyl (PEP) reacts with shikimate-3-phosphate (S3P) to produce 5-enolpyruvylshikimate-3-phosphate (EPSP) and inorganic phosphate. Because the shikimate pathway is absent in animals, but is essential for plants and microrganisms, EPSPS i

8. Technical the application of glyphosate to agricultural product certifications / Tecnologia de aplicação do glyphosate para certificação de produtos agrícolas
This study was carried out to define parameters for glyphosate application in controlling the Brachiaria decumbens grass, by using a centrifugal pulverization system to establish possible technical criteria that can be screened. The pulverization system was developed on such a way to provide uniform pulverization conditions, therefore turning possible the ob

9. Control de lecheron (Euphorbia dentata) con glifosato
Euphorbia dentata is an annual, spring-summer weed present in 85% of the agricultural land of the District of Azul, province of Buenos Aires, Argentina. Field studies were conducted during two years with the aim of (i) adjusting the dose and time of application that would achieve an efficient control of E. dentata with glyphosate and (ii) studying the use of

10. Glyphosate no controle de Brachiaria brizantha em áreas cultivadas com Tifton 85 (Cynodon spp.) / Glyphosate on Brachiaria brizantha control in areas cultivated with Tifton 85 (Cynodon spp.)
Brachiaria brizantha, a forage specie, is considered weed of difficult control when in pasture of Tifton 85 because, of its high capacity of interference and multiplication. Being important to search alternatives of controlling B. brizantha and the necessity to know real effects of glyphosate on Tifton 85 plants, three experiments were carried out in order t

11. Complexos metálicos com o herbicida glifosato: revisão
We present studies involving metallic ions and the herbicide glyphosate. The metallic complexes of Cu(II), Zn(II), Mn(II), Ni(II), Cd(II), Pb(II), Cr(III), Fe(III), Co(III), ammonium, sodium, Ag(I), alkaline earth metals and of some lanthanides ions are described. The complexes are discussed in terms of their synthesis, identification, stability and structur

12. Disposições de bicos para aplicação de herbicida em jato dirigido na cana-de-açucar (Saccharum spp)
This work reports a study developed to permit the use of non-selective herbicide in postemergence application on reinfcsted areas of sugarcane crops for weeds control. The research was developed in three stages. In the tirst ç)l1e,the available nozzles in the market which are indicated for minimum dritl applications were chosen. The sclected nozzles were: T
