1. Weed Management and Herbicide Selectivity in Ornamental Plants
RESUMO: A área de floricultura e paisagismo exibe os mesmos problemas que as culturas agrícolas quando se trata do manejo de plantas daninhas. Nestes cultivos as plantas daninhas afetam o rendimento e a qualidade do produto colhido, destacando-se na produção de flores e no paisagismo o aspecto visual e a estética como os fatores mais importantes. Na flo

2. Competitive Ability of Canola Hybrids Resistant and Susceptible to Herbicides
RESUMO: Este trabalho objetivou comparar a habilidade competitiva de híbridos de canola, suscetível (convencional) ou com resistência aos herbicidas do grupo das triazinas ou das imidazolinonas, com o nabo. Os experimentos foram conduzidos em casa de vegetação, no delineamento inteiramente casualizado com quatro repetições. Foram utilizados os híbrid

3. Efficacy and selectivity of alternative herbicides to glyphosate on maize
ABSTRACT The aim was to evaluate the selectivity and weed control of herbicides atrazine, nicosulfuron, mesotrione and tembotrione, applied alone and associated, in post-emergence of maize. Were carried out two experiments, one in the field in a randomized complete block design with four replications and eleven treatments, the second in greenhouse in a compl

4. Differential Tolerance of Clones of Eucalyptus grandis Exposed to Drift of the Herbicides Carfentrazone-Ethyl and Glyphosate
RESUMO: A deriva dos herbicidas carfentrazone-ethyl e glyphosate pode afetar o crescimento inicial do eucalipto. Este trabalho objetivou avaliar o efeito da deriva de carfentrazone-ethyl e glyphosate sobre a fotossíntese, a morfoanatomia foliar e o crescimento inicial de dois clones de Eucalyptus grandis. Foram realizados dois ensaios em esquema fatorial 2

5. POTENTIAL DRIFT AND INJURY OF HERBICIDES SPRAYED IN A WIND TUNNEL
ABSTRACT The possibility of synthetic auxin applications in crops increases the risk of injury to sensitive plants. The aim of this study was to quantify the drift of herbicides sprayed in a wind tunnel and the injury in cotton plants. The experimental design was a completely randomized design with five treatments and four replications. The tested spray solu

6. Increased immunoglobulin production in silver catfish (Rhamdia quelen) exposed to agrichemicals
Fish vaccination has been increasingly exploited as a tool to control pathogen infection. The production of immunoglobulin following vaccination might be affected by several factors such as management procedures, water temperature, and the presence of xenobiotics. In the present study, we aimed to investigate the kinetics of immunoglobulin production in silv

7. Effect of soil interacting herbicides on soybean nodulation in Balcarce, Argentina.
Two trials were performed in Balcarce, Argentina (37 graus 45' LS; 58 graus 18' LW) during 1993-94, to assess the effect of eight herbicides applied individually or in tank mixtures, on nodule number, nodule dry weight, seed yield and N percent in seed in soybean Asgrow 3205, inoculated with Bradyrhizobium japonicum CB 1809. Individual herbicides and doses i

8. AvaliaÃÃo do impacto do uso de agrotÃxicos nos trabalhadores rurais dos MunicÃpios de Ribeiro GonÃalves, Baixa Grande do Ribeiro e UruÃuà â Piauà / Evaluation of the Impact of the use of Pesticides on Agricultural Laborersâ Health in the Cities of UruÃuÃ, Ribeiro GonÃalves and Baixa Grande do Ribeiro
The pesticides are some of the main risky factors for agricultural laborersâ health. In the state of PiauÃ, the agricultural expansion which was implemented in the cerrados through the growth of the soy crops in the 90âs was a relevant factor that increased the use of pesticides. The unbalanced usage of pesticides is often related to acute and chronic poi

9. IMIDAZOLINONE TOLERANT RICE: RED RICE CONTROL, HERBICIDE PERSISTENCE AND OUTCROSSING / ARROZ TOLERANTE A IMIDAZOLINONAS: CONTROLE DO ARROZ VERMELHO, PERSISTÊNCIA DE HERBICIDAS E FLUXO GÊNICO
Red rice (Oryza spp.) is one of the main limiting factors to rice (O. sativa L.) yield. After several decades searching for red rice control tools, it was developed imidazolinone tolerant rice, to selectively control red rice. To better understand this technology it were conducted two experiments in 2004/05, in Santa Maria, Rio Grande do Sul state, Brazil. T

10. ALTERNATIVAS DE CONTROLE QUÍMICO DO ARROZ-VERMELHO E PERSISTÊNCIA DOS HERBICIDAS (IMAZETHAPYR + MAZAPIC) E CLOMAZONE NA ÁGUA E NO SOLO / CHEMICAL RED RICE CONTROL AND PERSISTENCE OF (IMAZETHAPYR + IMAZAPIC) AND CLOMAZONE IN SOIL AND WATER
Weed infestation, mainly with red rice (Oryza spp.), is the most important factor limiting yield increase in paddy rice in Rio Grande do Sul state. Chemical red rice control is the most used tool in this area. But, its use can originate herbicide residue in water and soil that can cause carry-over to rotational crops and environmental contamination. To asses

11. Dominant mutations causing alterations in acetyl-coenzyme A carboxylase confer tolerance to cyclohexanedione and aryloxyphenoxypropionate herbicides in maize.
A partially dominant mutation exhibiting increased tolerance to cyclohexanedione and aryloxyphenoxypropionate herbicides was isolated by exposing susceptible maize (Zea mays) tissue cultures to increasingly inhibitory concentrations of sethoxydim (a cyclohexanedione). The selected tissue culture (S2) was greater than 40-fold more tolerant to sethoxydim and 2

12. Specific binding of a dichloroacetamide herbicide safener in maize at a site that also binds thiocarbamate and chloroacetanilide herbicides.
Dichloroacetamide safeners such as N,N-diallyl-2,2-dichloroacetamide and (R,S)-3-dichloroacetyl-2,2,5-trimethyl-1,3-oxazolidine protect maize (Zea mays) against injury from thiocarbamate and chloroacetanilide herbicides. Binding activity of tritium-labeled (R,S)-3-dichloroacetyl-2,2,5-trimethyl-1,3-oxazolidine (15 Ci/mmol; referred to as [3H]Saf) was charact
