| The impact of an ad valorem pesticide tax on cropping patterns and pesticide use was examined in the South Central Texas Crop Reporting District. Output supply equations were econometrically estimated and used in the simulation. A 25 percent tax on pesticide was estimated to have major impacts on cropping patterns and on pesticide use. Assuming other input and output prices were unaffected, the supply of one important crop would fall by more than half. Demand for some of the highly soluble and persistent pesticides, which present the greatest threat to groundwater quality, would also decrease substantially (some as much as 50 percent). |

| Pesticides have become a major farm production cost over the past 25 years. There are price and label differences for agricultural herbicides between the United States and Canada. Trade names are different in some cases, label restrictions vary, and weights and measures are different. The reasons for the price differences are unclear. Whether they are due to increased costs in labeling requirements, different levels of competition and use, or market segmentation is not determined. The largest total impact of using lower priced Canadian herbicide is on HRSW, followed by durum and corn. The largest per acre impact is for canola, corn, and HRSW. Herbicides with the largest total impact are Puma, followed by Roundup and Fargo. Net farm income for large,... |

| Using an augmented profit function framework designed to account for externalities related to chemical use in agriculture, this paper explains the chemical use choices of farmers in an urban fringe farming environment. It further estimates empirical logit models of reduced insecticide, fungicide, herbicide, and fertilizer usage. Results suggest that farmers who perceive their regulatory environment to be strict, who have experienced right-to-farm conflicts, and who have farms larger in size are more likely to reduce their chemical use over time, vis-à-vis other farmers. The results also suggest the importance of other farm structural and business climate factors in determining chemical use reduction choices. |

| Pesticides are an important farm input both in terms of cost and in terms of their impact on crop yields and quality. With freer trade in agricultural output, differences in cost of production, yield and quality can have a large effect on competitiveness. Thus there is an increased demand by farmers in Canada and the United States for harmonization of pesticide regulations, and in particular for the option to import registered pesticides for their own use. Under NAFTA the three national governments are moving to make pesticide regulation more uniform, but there are still significant differences in regulatory structure and these effectively preclude direct imports by farmers at this time. Moreover, while farmers believe they would as a group benefit from a... |

| The number of insecticide applications made by an apple grower to control an insect infestation is modeled as a geometric random variable. Insecticide efficacy, rate per application, month of treatment, and method of application all have significant impacts on the expected number of applications. The number of applications to control a given insect population is dependent on the probability of achieving successful control with a given application. Results suggest that northeastern growers have the highest and mid-Atlantic growers the lowest probability of controlling an infestation with a given application. Results also indicate that scales require the least and moths the most number of applications. Growers are not responsive to per unit insecticide... |

| Pesticides play an important role in agriculture, prevent loses by pests which destroy cultures and causes several damages to producers and to exporting countries of agriculture products. However, pesticides leave residues where they are used. A parameter used for residue quantification is known Maximum Residue Limit (MRL). This parameter is the most important, not only in terms of public health, but mainly international trade, causing many impacts that can represent, in some cases, barriers to trade between countries, especially when established values for a country differ from those established by international organizations. The present Article show how this parameter impacts agriculture products´ trade of developing countries, based on case study. |
