Transparent model oils are commonly used to study the flow patterns and pressure gradient of crude oil-water flow in gathering pipes. However, there are many differences between the model oil and crude oils. The existing literatures focus on the flow pattern transition and pressure gradient calculation of model oils. This paper compares two most commonly used model oils (white mineral oil and silicon oil) with Xinjiang crude oil from the perspectives of rheological properties, oil-water interfacial tensions, emulsion photomicrographs and demulsification process. It indicates that both the white mineral oil and the crude oils are pseudo plastic fluids, while silicon oil is Newtonian fluid. The viscosity-temperature relationship of white mineral oil is similar to that of the diluted crude oil, while the silicon oil presents a less viscosity gradient with the increasing temperature. The oil-water interfacial tension can be used to evaluate the oil dispersing ability in the water phase, but not to evaluate the emulsion stability. According to the Turbiscan lab and the stability test, the model oil emulsion is less stable than that of crude oil, and easier to present water separation.

Studies on the chemical control of sucker growth on cigar tobacco showed that a mineral oil-water emulsion applied to the stub of the broken stem after the plant was decapitated and diethanolamine salt of maleic hydrazide sprayed on the leaves suppressed sucker growth significantly and increased the yield of the cured crop. Each chemical treatment resulted in a decrease in the percentage content of total alkaloids, nicotine, calcium, and total ash in the cured leaf but had no apparent influence on the content of total nitrogen, nornicotine, potassium, phosphorus, magnesium and chlorine.

Primeiramente, avaliou-se o espectro de gotas, empregando-se o delineamento inteiramente casualizado (DIC), em parcela subdividida, avaliando-se quatro soluções de aplicação (Parcelas): água; água + óleo mineral; água + glifosato; água + óleo mineral + glifosato e três modelos de pontas tipo leque(Subparcelas): simples (SL); duplo (DL) e duplo com indução de ar (DLI), com seis repetições. Determinou-se o diâmetro da mediana volumétrica; densidade de gotas; amplitude relativa e o potencial risco de deriva. Na etapa seguinte à deriva foi quantificada em túnel de vento, empregando o DIC em parcela sub subdividida, sendo avaliadas as quatro soluções de aplicação (Parcelas), os três modelos de pontas (Subparcelas), em duas velocidades de vento (Sub subparcelas): 1,0 e 2,0 m s-1, com quatro repetições. Independentemente da solução de aplicação, a ponta DL apresentou os maiores valores de deriva, seguida da SL e DLI, respectivamente. A solução de aplicação água + óleo mineral + glifosato, proporcionou os menores valores de deriva para todas pontas hidráulicas avaliadas. A interação do glifosato com o óleo mineral, aplicado com a ponta DLI, tem potencial para reduzir a deriva no campo.   Palavras-chave: tecnologia de aplicação, túnel de vento, espectro de gotas, redução de perdas, controle de qualidade.   Interactions between adjuvant and hydraulic nozzles in the control of glyphosate drift   ABSTRACT: The aim of this work was to analyze the interactions between adjuvant and the hydraulic nozzle in glyphosate drift control. Firstly, the droplet spectrum was evaluated using a completely randomized design (DIC) in a split plot, evaluating four application solutions (plots): water; water + mineral oil; water + glyphosate; water + mineral oil + glyphosate and three nozzle spray models (subplots): simple (SL); double (DL) and double with air induction (DLI), with six repetitions. The diameter of the volumetric median was determined; droplet density; relative amplitude and the potential risk of drift. In the following stage the drift was quantified in a wind tunnel, using the sub-subdivided DIC, being evaluated the four application solutions (parcels), the three nozzle spray models (subplots), in two wind speeds (sub-plots): 1.0 and 2.0 m s-1, with four repetitions. Regardless of the application solution, the DL tip presented the highest drift values, followed by SL and DLI, respectively. The application solution water + mineral oil + glyphosate, provided the lowest drift values ​​for all hydraulic tips evaluated. The interaction of glyphosate with mineral oil, applied with the DLI tip, has the potential to reduce drift in the field.   Keywords: application technology, wind tunnel, spectrum of drops, loss reduction, quality control.

The properties of two DDT suspensions of a new type, “Supona”-D and “Supona”-DB are described. These suspensions contain about 50 per cent. DDT or 39 per cent. DDT+ 13 per cent. technical BHC respectively in their concentrated forms, the active material being suspended in a complex colloidal oil-water system.Experiments were carried out with “Supona”-D and a DDT emulsion containing about 30 per cent. DDT dissolved in a mineral oil phase for the control of Glossina palpalis. Both products were applied in dilutions containing 5 per cent. DDT.Laboratory experiments with leaves of Camellia thea and Begonia sp. showed that the initial toxicity and stability in tropical sunlight of residues of “Supona”-D were somewhat less than those of the DDT emulsion. The resistance to rain, however, was better with residues of “Supona”-D.
