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 for the Soy-IPM. A recent survey made with official and private technical assistant professionals showed that biological control of velvetbean caterpillar is estimated to be used on 10% of Parana State soybean farms, whileuse of the mixture of sodium chloride plus insecticide to control soybeanstink bugs reaches almost 25% of the soybean area, in the same state. This last techiniques, developd by Embrapa, allows the reduction of the insecticide rate by 50%, with the same effects observed on the pests when the insecticides are applied at the full rate. For the control of stink bugs, Soy-IPM users applied once a season against 1.4 applications for non adopters. as for the control of the VBC non-users applied 1.8 sprayings/seasons against 0.6 sprayings for the Soy-IPM users. Endosulfan and monocrotophos represented 37% of the insecticide used to control VBC and 73,5 of the pesticides applied for stink bug control.

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. |
