Cobertura e depósito de calda fitossanitária em plantas de café pulverizadas com equipamento original e adaptado para plantas altas

The objective of this study was to evaluate the coverage of spray droplets on coffee plants as well as their deposition using a sprayer with and without adaptation of an auxiliary branch for tall plants. The experiment was conducted following a randomized block design with six treatments and four replications to evaluate the percentage of coverage for the spraying liquids in water sensitive paper fixed at four quadrants and two heights (lower and upper) of the plants, and the spray deposit with metallic marker (MnSO4) on sheets in the same positions of the water sensitive paper in two spray volumes (450 and 750 L h(-1)). The experiment was conducted in October 2011 in the town of Patroc nio-MG, and the experimental plots consisted of 30 plants of Catua IAC-99, with approximately 12 years of age and average height of 3.50 meters. The experiments were conducted following a randomized block design with six treatments and four replications to evaluate the coverage and deposition, in two spray volumes (450 and 750 L ha(-1)). Leaves were collected in four positions and also at the top four in the lower canopy. The results of the evaluations were analysed statistically by F test and for comparison of means by Tukey test at 5% probability. The auxiliary branch installed at the rear of the equipment is the most suitable when compared to use of equipment without this feature or installed in the front of the equipment. Furthermore, the application volume of 450 L ha(-1) results in coverages and deposits of spraying liquids equivalents to volume of 750 L ha(-1), considered sufficient according to the parameters evaluated.

Equipamentos de pulverização associados a volumes de calda e avaliados por alvos artificiais em cafeeiro

The aim of this study was to evaluate the quality of spray droplet spectrum on coffee tree, by using different equipments and syrup volumes. The experiment was set up in a coffee farm, Acaiá variety, Campos Gerais city, MG, Brazil. The treatments were three syrup volumes (150, 300 and 600 L/ha). The lower volume was sprayed with the pneumatic sprayer Martignani, Whirlwind B612 Autonom-Trac mode, and the other volume rates using the conventional hydraulic sprayer to coffee tree. It was possible concludes that the spray volume can be reduced in applications on coffee tree using the pneumatic sprayer.

Economic Policies to Address the Environmental Consequences of Global Reuse

This paper summarizes a two-country model that solves for optimal tax rates to achieve efficiency in an economy with international trade in used consumer electronics. If only the developed nation can tax the disposal of e-waste, then the global Pareto Optimum can be obtained by either imposing an import tariff on used consumer electronics or subsidizing the return of e-waste for disposal in the developed country. The global Pareto Optimum can also be obtained by reducing the disposal tax in the developed country to a level below the external marginal cost of disposal should no other policy option be available.

Trade policy in a dynamic Heckscher-Ohlin model

The Import Substitution Process in Latin Amer ica was an attempt to enhance GDP growth and productivity by rising trade barriers upon capital-intensive products. Our main goal is to analyze how an increase in import tariff on a particular type of good affects the production choices and trade pattern of an economy. We develop an extension of the dynamic Heckscher-Ohlin model – a combination of a static two goods, two-factor Heckscher-Ohlin model and a two-sector growth model – allowing for import tariff. We then calibrate the closed economy model to the US. The results show that the economy will produce less of both consumption and investment goods under autarky for low and high levels of capital stock per worker. We also find that total GDP may be lower under free trade in comparison to autarky.
