1. Bioassay for detection of transgenic soybean seeds tolerant to glyphosate.

Glyphosate is a systemic, nonselective, postemergence herbicide that inhibits growth of both weeds and crop plants. Once inside the plant, glyphosate interferes with biosynthesis of aromatic amino acids phenylalanine, tyrosine, and tryptophan, by inhibiting the activity of 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), a key enzyme of the shikimate pat

2. Performance of transgenic and conventional soybean plants subjected to bioassay for detection of glyphosate tolerant seeds

Abstract The adoption of genetically modified soybean cultivars is increasing annually around the world, which indicates the excellence of these genotypes. For soybean breeding, the use of such cultivars in a backcross program relies on the ability to detect the transgenic trait. The germination test in a moistened substrate with glyphosate is effective and

3. Spider mites associated to soybean in Rio Grande do Sul, Brazil.

The objective of this work was to study the occurrence and geographic distribution of phytophagous mites associated to soybean in Rio Grande do Sul, Brazil. Samplings were performed from January to May 2005 on genetically modified soybean (glyphosate-tolerant) crops, in 27 municipalities of six regions ?

This work has aimed to evaluate the quality of glyphosate-tolerant seeds of soybean genotypes of early, mid-, and late season, produced in adequate conditions. Experiments took place in two phases. Firstly, in a field one, with three variety competition trials; 6 glyphosate-tolerant genotypes of soybean were evaluated: early season (BR01-71210, BR02-64301, B

RESUMO A evolução de plantas daninhas resistentes e tolerantes ao glyphosate tem causado mudanças no manejo de plantas daninhas em todo o mundo. Herbicidas residuais são cruciais para o manejo dessas plantas daninhas, porém a taxa de adoção dessas ferramentas ainda é significativamente baixa no Brasil. Nesta pesquisa, Ipomoea triloba tolerante ao gly

7. Germinação, competitividade com a cultura da soja e resposta biológica a aplicações de glyphosate para plantas de trapoeraba (Commelina benghalensis L.) / Germination, competitiveness with the soybean crop and biologic response to glyphosate applications of Bengal dayflower plants (Commelina benghalensis L.)

In areas where the herbicide glyphosate is used frequently, populations of the weed Bengal dayflower (Commelina benghalensis) have been selected, due to the species tolerance to the action of that herbicide. This way, the use of alternative management is necessary, which are dependent upon deep knowledge on species biology; as well as, the efficient chemical

8. Nitrogenous nutrition in conventional and transgenic soybean under application of herbicide glyphosate / Nutrição nitrogenada (15N) em soja convencional e transgênica sob aplicação do herbicida glifosato

Glyphosate is the most used herbicide throughout the world in post-emergent applications of weed species, before sowing or emergence of the cultures. Many works have been performed to understand the way of action of this herbicide, but few with the purpose to study its effect on the microbial populations of the soil, as the Bradyrhizobium japonicum populatio

The Roundup Ready (RR) soybean facilitated weed management by allowing the use of glyphosate in all stages of crop development. But the continuous use of this herbicide can select resistant weed biotypes and tolerant species, suggesting the need of developing new management practices. Thus, the aim of this proposal was to evaluate the effectiveness of differ

Genetically modified soybean, tolerant to glyphosate, expanded its growing area in few years becoming the most sown in the country. The advantages of its use are many compared to the conventional soybean, which has led soybean farmers to prefer it. However, since some markets still prefer conventional soybean and its production occurs in smaller areas, there
