Conteúdo:  During the early 1970s, a survey demonstratedthat insecticides were the exclusive soybean pest control method. An average of 6 applications/season were made, using very high toxic and enviromentaly hazardous insectides, and also at far higher rates than needed. To address this situation a Soybean Integrated Pest Management program (Soy-IPM) was designed, validated and implemented in Brasil, starting in 1975. The process represented an interaction between R & D instittutions (Universities, Research Institutes), Extension and Technicl Assistance Institutions (Former Embrater system, Cooperatives, Private offices, NGOs), leadede by Embrapa Soja. Early studies and implementation were set up simultaneously at Parana and Rio Grande do Sul states, followed by quick spreading to all over the Brazilian soybean cultivated region. The peak for IPM adoption (ca.70%) happened during the 1982/83 growing season, after intensive integrated efforts to expand the program. Nowadays, an adoption index of 40% was observed from the surveys made at the grower level. Financial accumulated returns for the last 25 years are estimated to vary from conservative US$750 million to in excess of US$ 4 billions, according to calculation methodology. The gross value of harvested Brazilian soybean for last season, at the farm level, was US$4,5 billions. The accumulated EMBRAPA's overall budget for the last 25 yr ranked bellow US$6billions, and these figures are very useful to establish the cos/benefit raio fo... Mostrar Tudo

Título:  Alternative approaches applied to inductively coupled plasma techniques: multi-flow and two-flow calibration.

Conteúdo:  Multi-flow calibration (MFC) is based on monitoring the analytical signal from a single calibration standard solution at several different nebulization gas flow rates (Q), which normalizes plasma conditions and minimizes matrix effects. In the present study, MFC was evaluated, for the first time, applied to inductively coupled plasma optical emission spectrometry (ICP OES) and inductively coupled plasma mass spectrometry (ICP-MS) to analyze different and complexmatrix samples. Al, As, Cd, Cr, Cu, Mn, Pb, and Zn were determined by ICP OES, while As, Cd, Co, Cu, Hg, Mo, Mn, Ni, Se, Sb, Pb, and V were determined by ICP-MS. MFC results were compared with those obtained using external standard calibration (EC) for both techniques and in all cases, MFC showed equal or superior accuracy (recoveries between 80-120%) compared to EC, and lower relative standard deviation (RSDs < 10%). Several tests were also performed using only two nebulization gas flows to build linear models for calibration (called two-flow calibration, TFC) and the accurate results (recoveries ranged from 80 to 110% for ICP OES and from 81 to 102% for ICP-MS) suggests that this strategy can be also applied, resulting in a method with high sample throughput.
