| The goal of this work was to evaluate the effect of spray volume on the moisture of the stored grains of the corn and wheat. Two kg of each type of the grain were placed into the plastic bags and sprayed with the theoretical doses of 0, 1, 3, 5, 8, and 10 liters of water / ton of the grain. The grain moisture content was evaluated 24 h after the spray operation by the oven method. The increase in the grain moisture was quadratic and showed the same trend in both the corn and wheat. The grain moisture after spraying 10 L.t-1 showed little increase (0.8 %) as compared to the initial moisture content. Thus, the application of any spray volume as used in this study made no difference for a possible better uniformity in the distribution of insecticide... |

| The objectives of this study were to evaluate the residues of the insecticide carbosulfan and its carbofuran metabolites and 3-hydroxy-carbofuran in orange compartments (whole fruit, bagasse and juice) and comparison between the residual levels found in fruits with the maximum residue level and the safety interval established by the Brazilian legislation. Two field experiments were carried out, both with the following treatments: a-check; b-one application of 10 g of carbosulfan . 100 L-1 of water; c-one application with twice the rate applied in treatment b; d-four applications with the same rate applied in treatment b. Samples were taken at (-1), zero, 1, 3, 7, 14, 21 and 28 days after the last or unique application. The quantitative determinations were... |

| O objetivo do presente estudo foi avaliar a degradação/persistência do inseticida piretróide deltametrina em grãos de trigo e em seus produtos processados, a saber: farelo, farinha branca, farinha integral e pão. Os grãos foram tratados de modo a alcançar a concentração teórica de 0,35 mg kg-1 do piretróide. As amostras foram tomadas a zero, 15, 30, 60 e 90 dias após a aplicação. Houve tendência de concentração do piretróide no farelo de trigo e um menor acúmulo nas farinhas, sendo que após o processo de cozimento do pão observou-se perda do inseticida. |
