A ferrugem asiática foi constatada na safra 2001/2002 nos Estados do Rio Grande do Sul, Paraná, Minas Gerais, São Paulo, Mato Grosso do Sul, Mato Grosso, Santa Catarina e Goiás. Na última safra 2002/2003, verificou-se a ocorrência da referida doença em parcelas de experimentos na Embrapa Cerrados, Planaltina, Distrito Federal. Ocorreu um nível de desfolha baixo em algumas parcelas, sendo que na maioria foi feito o controle com fungicida. observou-se, também, a presença da doença em lavouras de produção de semente básica na Fazenda Sucupira, do Serviço de Transferência de Tecnologia, no Riacho Fundo II, também no DF. Nesse local, em lavouras com a cultivar BRS Raimunda, e com a linhagem BRAS 97-0082, a doença ocorreu no estádio R5.3 e R5.2, respectivamente. Foi feita uma aplicação de fungicida nessa fase, sendo verificadas perdas de produtividade de aproximadamente 40% na cultivar BRS Raimunda e 20% na linhagem BRAS 97-0082. Constatou-se igualmente a ocorrência da ferrugem asiática em lavouras comer-ciais de sementes e grãos na região produtora do Distrito Federal.

Various studies have demonstrated the presence at high levels of pesticides and nitrate in soil, surface, and groundwater. Prior studies have identified a watershed area in Brazil with a high risk of soil, surface, and groundwater contamination by pesticides at the region of Riberao Preto, SP. Surface and groundwater were collected at the area during the period of October 1995 to November 1998. By means of gas chromatography-mass spectrometry (GC-MS) technique the herbicides tebuthiuron, diuron, simazine, atrazine, and ametryne, and nitrate were analyzed according to the protocols established in literature. The recovery obtained in the extraction procedure was higher than 95% for all herbicides except simazine for which the recovery was 85,6%. Due to the enrichment in the extraction procedure and the sensitive detection at two wavelengths it was possible to obtain a quantification limit of 0.02 ug/L for the herbicides studied. The method was linear over the range of 0.02 to 2.0 ug/L. Soil data showed a higher level of the herbicide tebuthiuron, at the levels of 59.6 ppb; than the other applied during all the months. The results have shown the hercicide tebuthiuron as the one with higher concentrations in groundwater and in January of 1996 the concentration found was 0.08 ug/L, close to the maximum allowed, 0.1 ug/L, but this fact was not consistent during the other months. No residue of the other herbicides was detected. In case of nitrates, with maximum level allowed of 10 mg/L, it was found the maximum of 0.9 mg/l, but in a shallow well inside the area. Commercial wells at the edge of the watershed showed low levels of nitrate, below the risk level, but with potential for dangerous contamination.
